Grusec Joan Grusec is Professor of Psychology at the University of Toronto, where she first learned of social-learning theory as an undergraduate. She found it exciting enough to trek off to Stanford University for graduate work with Albert Bandura, abandoning her plans to be a social worker or a historian. Since then, she has been an advocate, chronicler, and modifier of social-learning theory. Her early work with Bandura focused on imitation. Later she studied children’s prosocial behavior and parents’ discipline processes. She was interested in what makes parents effective in achieving their socialization goals and what makes some parents more effective than others. She found that parents’ effectiveness depended on the child’s age, the parent’s emotional state, and the cultural context. Grusec is a Fellow of the Canadian Psychological Association and the American Psychological Association and has been Associate Editor of the journal Developmental Psychology. She believes that developmental psychology is the most exciting area of psychology because it is the only one that brings together under one umbrella a concern with how biology and culture interact over the course of time to make us what we are.

Annual Review of Psychology, 62, 243–269. 3 Chapter 1 Introduction: Theories of Social Development Barbara Rogoff Barbara Rogoff, Professor of Psychology at the University of California, Santa Cruz, has been a major force in bringing attention to the role of culture in children’s development. Like many others in the field, she did not plan to be a psychologist. She started out to be a cartoonist and majored in art. Her cultural journey began when as a graduate student at Harvard she became involved in research in a Mayan town in Guatemala. After discovering that how these people thought and acted was closely related to their social experiences, she began a career examining how people learn, how other people help them learn, and how this varies in different cultural communities. Through her work in different cultures and in a wide array of settings from classrooms to Girl Scouts to school drama groups, she showed how cultural rules govern social development. In her book, Apprenticeship in Thinking, she demonstrated the value of Vygotsky’s theory as a way to understand how learning takes place in routine everyday social interactions with parents, siblings, and peers. For Rogoff, the pressing issue for the field of social development is how to foster children’s development in ways that respect the differences in the values and practices of their cultural communities. Rogoff has received many honors for her work. She is a Fellow of the American Psychological Society, the American Psychological Association, and the American Anthropological Association. She has served as a committee member on the Science of Learning for the U.S. National Academy of Sciences. She sends this message to students: “You are the generation that can make a real difference in how we understand and foster children’s development in the varying communities of the United States and the world. I hope you continue to think about these issues long after you finish reading this book.” Further Reading Rogoff, B. (2011). Developing destinies: A Mayan midwife and town. New York: Oxford University Press. 4 Chapter 1 Introduction: Theories of Social Development David Bjorklund David Bjorklund is Professor of Psychology at Florida Atlantic University. He has taught there for more than 30 years, since completing his Ph.D. work at the University of North Carolina. As an undergraduate, Bjorklund wanted to be a clinical child psychologist “saving the world by curing one neurotic child at a time.” However, the reality of working with delinquent youth during college made him realize that he was not cut out for a clinical career but was more suited to research. After a lengthy period doing research on children’s cognitive development, Bjorklund became an eloquent spokesman for the evolutionary theoretical perspective. His views are described in his book The Origins of Human Nature: Evolutionary Developmental Psychology, which was the first extended treatment of an evolutionary approach to development. Bjorklund believes that our unique intelligence is not technological ability but an ability to negotiate the social environment, to cooperate with others, and to understand their intentions and desires. The central question that concerns him is how human social intelligence evolved. He suggests that many social development issues can be better understood through an evolutionary lens. For example, although child abuse and young males’ aggression are no longer adaptive in modern environments, they may have been adaptive in our evolutionary past. Bjorklund hopes that in the future the field will embrace more biological ideas including not only evolution but also the effects of hormones and the central nervous system on social behavior. He has been widely recognized for his work, receiving the Alexander von Humboldt Research Award and invitations to be a visiting professor in Germany, Spain, and New Zealand. He is editor of the Journal of Experimental Child Psychology and served as a contributing editor to Parents Magazine. He advises undergraduates to do what works for him, “Write to see what you think.” Further Reading Bjorklund, D. F., & Pellegrini, A. D. (2011). Evolutionary perspectives on social development. In P.

Summarize the historical foundations of the study of social development. 3. Understand the critical questions of social development (biological and environmental influences; role children play in their own development; appropriate unit for studying social development; continuous and discontinuous development; role of the situation vs. the child; universality of social development; variation across historical eras; social development as related to other domains; importance of mothers vs. others; single vs. multiple pathways of development; influences on judgments of children’s social behavior). 4. Understand each of the theoretical perspectives presented in this chapter. 5. Describe the strengths and weaknesses of each theoretical perspective. 6. Explain why several complementary theories are needed for the study of social development. 6 Chapter 1 Introduction: Theories of Social Development Chapter Summary Social Development The field of social development includes descriptions of social behaviors, individual differences in social behavior, and changes in social behavior with age as well as explanations for these changes and differences. Social Development: A Brief History The scientific study of social development began with Darwin’s work in the 1800s. Subsequently, competing views were expressed in Watson’s behaviorally oriented theory, Freud’s biologically inspired theory, and Gesell’s maturational theory. Critical Questions about Social Development How do biological and environmental influences affect social development? Modern developmental psychologists recognize the importance of both biological and environmental influences and are concerned with discovering the ways in which these factors interact to produce developmental differences. What role do children play in their own development? Most developmental psychologists believe that children actively shape, control, and direct the course of their own development. What is the appropriate unit for studying social development? Although researchers have typically focused on individual children, they have increasingly recognized that other units such as dyads, triads, and social groups are also important. Is development continuous or discontinuous? Some theorists view social development as a continuous process whereby change takes place smoothly and gradually. Others see development as a series of qualitatively different stages or steps. The more closely we examine development, the more we see ebbs and flows in the acquisition of social skills. Is social behavior the result of the situation or the child? Most developmental psychologists stress the complementary roles of situational factors and child differences. Is social development universal across cultures? Most developmental psychologists agree that cultural contexts should be considered but believe that universal aspects of development such as emotions, language, and communication coexist with cultural variations. How does social development vary across historical eras? Both abrupt and gradual changes in society influence social development. Is social development related to other developmental domains? Social development influences and is influenced by emotional, cognitive, language, perceptual, and motor development. How important are mothers for children’s social development? Although mothers are clearly important in children’s social development, other people including fathers, siblings, grandparents, peers, teachers, and religious leaders also are important influences. Is there a single pathway for social development? Children may start out at a similar place but end up at very different points (multifinality), or they may follow different paths but end up at the same point (equifinality). What influences how we label children’s social behavior? Three sets of factors— characteristics of the child, the adult, and the context—influence social judgments and, in turn, how social behaviors are labeled. 7 Chapter 1 Introduction: Theories of Social Development Do developmental psychologists own social development? Scholars in a variety of fields including pediatrics, psychiatry, anthropology, economics, law, and history have made valuable contributions to the field of social development. Theoretical Perspectives on Social Development Theories help organize and integrate knowledge into a coherent account of how children develop and foster research by providing testable predictions about behavior. Historically, grand theories reflected attempts to account for all aspects of development. Modern theories tend to be more narrowly focused attempts to explain specific aspects of social development. Psychodynamic Perspective In Freud’s psychodynamic theory, basic biological drives motivate the child. Early experiences are essential for determining later behavior. Erikson expanded Freud’s theory to include social and cultural influences on development. His psychosocial theory is organized around a series of fundamental personal and social tasks that individuals must accomplish at each stage. Psychodynamic theories helped shape many concerns of modern social development, including the effects of early experience in the family and the psychological roots and importance of aggression, morality, gender roles, and attachment. However, the central claims of the theories are difficult to test empirically. Traditional Learning Perspective Traditional learning theories emphasize how new behaviors are acquired through a gradual and continuous process of learning. The theories had important applications and have been used in homes, schools, and clinics to reduce children’s behavior problems. Their lack of attention to developmental changes is a limitation. Cognitive Social Learning Theory Bandura focused attention on observational learning. The notions of reciprocal determinism and self-efficacy were important additions to this theoretical position. The lack of attention to developmental issues, the limited ecological validity of the findings, and the limited recognition of the roles of biology and culture are shortcomings of the theory. Social Information-Processing Theory This approach focuses on how children take in, use, and remember information to make decisions about social actions. The lack of developmental focus, the limited role allocated to emotion, and the heavy emphasis on deliberate decision making rather than automatic or habitual responding are limitations of this perspective. Cognitive Developmental Perspective In Piaget’s theory of development, children actively seek new experiences and from them construct mental structures. They assimilate new information into existing structures and accommodate structures when the information doesn’t fit. Piaget’s focus on stages has been questioned, and his lack of emphasis on emotions, culture, and social behavior make his theory of limited use in the field of social development. 8 Chapter 1 Introduction: Theories of Social Development Social Cognitive Domain Theory This perspective focuses on how children learn to make social judgments about their world. According to this approach, children’s social judgments are domain specific. Vygotsky’s Sociocultural Theory This theory focuses on the contributions of social and cultural factors to children’s development. Children grow and change as a function of their own efforts and the guidance of more skilled others. The theory does not describe how interactions change over the course of development. Systems Perspective According to systems theories, other elements or members of the system influence an individual’s behaviors. Bronfenbrenner’s ecological systems theory stresses the importance of relations between the child and environmental systems, such as the family, school, community, and culture. Development involves the interplay between the child and the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Lack of developmental focus as well as limited information about the processes that govern cross-level linkages are limitations of this theory. Biological Perspective Ethologists observe behaviors in natural settings and study patterns of behaviors across human and infrahuman species and across human societies and cultures. The theory is largely descriptive. Evolutionary psychology asserts that social behaviors reflect survival needs and processes of human evolution. It focused attention on parental investment as a way to ensure intergenerational continuity of genes and on the adaptive value of immaturity. A recent application of evolutionary developmental theory is “life history theory,” which suggests that the schedule of key events over the life course is influenced by natural selection to produce the largest possible number of surviving offspring and thus maximize the successful passing on of the organism’s genes. These key events include the age of sexual maturity and first reproduction, the number of offspring produced, and the level of parental investment in children. The approach has limited relevance for addressing issues associated with rapid changes. Many explanations are post hoc. Behavior genetics addresses the relative contributions of heredity and environment to social development and the interdependence between environmental conditions and whether and when genes are expressed in behavior. The particular genes or clusters of genes that account for social outcomes are still poorly understood, and the way in which the environment is measured is often very general. Life Span Theory This theory emphasizes development over the entire life course. Changes can be traced to normative age–graded events including entry into school, nonnormative events such as divorce, and historical or cohort-related events such as the Great Depression or the Vietnam War. The impact of this perspective is limited by the fact that much of the theorizing has involved older adults. 9 Chapter 1 Introduction: Theories of Social Development Variety of Theoretical Perspectives Social development can be approached from a variety of perspectives and it is often helpful to draw on several theories to explain children’s development. 10 Chapter 1 Introduction: Theories of Social Development Key Terms GLOSSARY TERMS age cohort People who were born in the same time period and share historical experiences. accommodation Modifying an existing schema to fit a new experience. assimilation Applying an existing schema to a new experience. chronosystem The time-based dimension that can alter the operation of all other systems in Bronfenbrenner’s model, from microsystem through macrosystem. classical conditioning A type of learning in which a new stimulus is repeatedly presented with a familiar stimulus until an individual learns to respond to the new stimulus in the same way as the familiar stimulus. cognitive social learning theory A theory that stresses the importance of observation and imitation in the acquisition of new behaviors, with learning mediated by cognitive processes. critical period A specific time in an organism’s development during which external factors have a unique and irreversible impact. desensitization Classical conditioning therapy used to overcome phobias and fears through exposure to increasingly intense versions of the feared stimulus. domain specificity Processes of development are different for different types of behavior, for example, moral judgments, manners, and peer relationships. drive-reduction theory A version of learning theory suggesting that the association of stimulus and response in classical and operant conditioning results in learning only if it is accompanied by reduction of basic primary drives such as hunger and thirst. ecological theory A theory stressing the influences of environmental systems and the relations between the systems on development. ego In Freud’s theory, the rational component of the personality, which tries to satisfy needs through appropriate, socially acceptable behavior. egocentric Tending to view the world from one’s own perspective and to have difficulty seeing things from another’s viewpoint.

Divide the class into smaller discussion groups to consider the following questions: How does one's theoretical view of development affect the kinds of behaviors one notices? What behaviors would be observed by Freud, Erikson, Piaget, Skinner, Bandura, Vygotsky, etc. if they were observing children on the playground over the course of one day? What additional information (if any) would each theorist like to have beyond the observed behaviors? Ask each group to nominate someone to write down the results of the discussion. Allow some time for discussion and then ask the groups to report and generate discussion. 2. Choose a few of the critical questions about social development and divide the class into smaller discussion groups. Each group should be divided into two smaller groups so that within each small group students can debate their assigned critical question. For example, one group will debate whether development is continuous or discontinuous. A second group will debate whether social behavior is the result of the situation or the child. Students should use information from their textbook to support their arguments. Then, reconvene the class and ask the groups to present their ideas and allow the class as a whole to weigh in on each debate. 3. The purpose of this activity is to have students apply the critical questions about social development to their own experiences. Ask students to imagine themselves when they were age 3. Then ask them to compare that 3 year old child to the way they are today. Ask them to give examples of the ways they are different in terms of their social behavior and the ways they might be the same. Then, ask them to think about what may have contributed to the changes or the similarities over time. Help the students to determine how their answers reflect nature vs. nurture, person vs. situation, cultural, and historical influences of development. 4. Using Student Handout 1-3, break the students into 4 smaller groups. Have each group work on one of the critical questions and have them determine where each theory falls with regard to that question and provide explanations for their answers. Have each group report back to the whole class. 14 Chapter 1 Introduction: Theories of Social Development Research Paper Topics 1. Watch the film NOVA: Secret of the Wild Child (1997), a documentary about Genie, the 13year-old girl who was rescued from her home by social workers after a decade with virtually no human contact. Apply what is learned in the film to the concepts of sensitive and critical period. Review at least three studies involving human and/or animal research that demonstrate the concepts of critical or sensitive periods (e.g., human infant attachment, imprinting). 2. Discuss the social dyad as a unit of study and how it is measured (see research on parentchild reminiscing by Robyn Fivush, Catherine Haden as examples). 3. Evaluate the usefulness of Vygotsky’s sociocultural perspective for understanding social development by a review of recent work inspired by this theory. 4. Review research that examines the role of self-concept or perception in peer acceptance or rejection as an illustration of the notion of reciprocal determinism. 5. Discuss continuous versus discontinuous models of development in view of recent evidence that there is an ebb and flow in the process of acquiring social behavior. 6. Describe and critique an evolutionary account of social development. 7. Is a life span perspective on social development with its focus on adult development a useful one for understanding social development? 8. What aspects of Freudian theory have left their imprint on contemporary studies of social development? 9. Describe and illustrate (by specific studies) the ecological systems theory of Bronfenbrenner. 10. Explain the importance of including historical change and culture in our studies of social development by providing research examples that examine these factors. 15 Chapter 1 Introduction: Theories of Social Development Articles, Chapters, Books to Supplement Textbook Overviews Bjorklund, D. F., & Pellegrini, A. D. (2011). Evolutionary perspectives on social development In P. K. Smith & C. H. Hart (Eds.), Wiley-Blackwell handbook of childhood social development (2nd ed.). Oxford, UK: Wiley-Blackwell. Spells out implications of the evolutionary viewpoint for social development. Evolutionary developmental psychology involves the expression of evolved, epigenetic programs, as described by the developmental systems approach, over the course of ontogeny. There have been different selection pressures on organisms at different times in ontogeny, and some characteristics of infants and children were selected in evolution to serve an adaptive function at that time in their life history rather than to prepare individuals for later adulthood. Examples of such adaptive functions of immaturity are provided from infancy, play, and cognitive development. Most evolved psychological mechanisms are proposed to be domain specific in nature and have been identified for various aspects of children's cognitive and social development, most notably for the acquisition of language and for theory of mind. Differences in the quality and quantity of parental investment affect children's development and influence their subsequent reproductive and childcare strategies. Some sex differences observed in childhood, particularly as expressed during play, are seen as antecedents and preparations for adult sex differences. Because evolved mechanisms were adaptive to ancestral environments, they are not always adaptive for contemporary people, and this mismatch of evolved mechanisms with modern environments is seen in children's maladjustment to some aspects of formal schooling. They argue that an evolutionary perspective can be valuable for developing a better understanding of human ontogeny in contemporary society and that a developmental perspective is important for a better understanding of evolutionary psychology. Bronfenbrenner, U., & Morris, P. A. (2006). The bioecological model of human development. In R. M. Lerner & W. Damon (Eds.), Handbook of child psychology (6th edition), Volume 1: Theoretical models of human development (pp 793-828). Hoboken, NJ: Wiley. Provides a thorough presentation of the ecological model of human development. The bioecological model is an evolving theoretical system for the scientific study of human development over time. The model presented in this chapter represents major theoretical innovations from the 1983 chapter in both form and content. The new model is not a paradigm shift, but rather represents a transition from a focus on the environment to a focus on proximal processes as engines of development. They begin with the defining properties of the model, which involves four principal components (process, person, context, and time), and the dynamic, interactive relationships among them. They then turn to the research designs required for testing the model. In doing so, they not only present the next stage in the evolution of an ecological theory of human development, but also document the requirements for conducting developmental research in the discovery mode. They conclude with a look to the future—and what the bioecological model means for the future development of our species. Cairns, R. B., & Cairns, B. D. (2006).

A 16 Chapter 1 Introduction: Theories of Social Development comprehensive summary and historical view of the field of developmental psychology. This chapter provides a synthesis of the historical foundations of developmental psychology. The roots of the developmental approach are traced from nineteenth-century concepts in psychology and allied disciplines (e.g., biology, developmental psychobiology, developmental psychopathology, ethology, and philosophy) to current perspectives of a holistic science of development. The genesis and contributions of major developmental theories are examined in relation to both their contemporary and historical contexts. James Mark Baldwin's pioneering developmental approaches bridging the study of social institutions (i.e., sociology) and individual functioning (i.e., psychology) are highlighted. Additional foundations of an integrative developmental science are explored in relation to the social applications of psychology. Collins, W. A. (2011).

Oxford, UK: Wiley-Blackwell. A historical perspective and a contemporary overview of the main issues that have concerned social development researchers and theorists over the past century. The chapter is organized around the division of the first century of social development into three periods: emergence (roughly 1890–1919), the middle period of institutionalization and expansion (1920– 1946), and the modern era (from 1947 to the present). These broad divisions reveal striking variations in the degree to which systematic theoretical perspectives influenced the dominant questions and methods of social development research. http://media.johnwiley.com.au/product_data/excerpt/93/14051967/1405196793-46.pdf Charlesworth, W. R. (1992). Darwin and developmental psychology: Past and present. Developmental Psychology, 28, 5–16. A look at the contributions made by Darwin to previous and current conceptions of developmental psychology. Addresses the historical question of what influence Darwin has had on the emergence of developmental psychology as a scientific discipline. Suggestions for possible synergistic connections between modern evolutionary theory and developmental psychology are offered. Darwin's distinctive contributions to evolutionary theory appear to have had less influence on developmental psychology than traditionally believed. Possible reasons for this include developmentalists' commitment to meliorism, conceptual issues characterizing differences between ontogenetic and phylogenetic change, and methodological differences in studying proximate and ultimate factors. It is suggested that developmentalists use evolutionary theory as a heuristic for structuring new research into human development. In return, evolutionary biologists can have hypotheses concerning the impact of phylogeny on human ontogeny tested by those best qualified to test them. Chen, X ., Chung,J., Lechcier-Kimel, R.

Lewis, M. D. (2000). The promise of dynamic systems approaches for an integrated account of human development. Child Development, 71, 36–43. Describes the dynamic systems perspective and helps to explain how development proceeds using principles of selforganization. After decades of theoretical fragmentation and insularity, a converging explanatory framework based on general scientific principles is an important goal for developmental psychology. Dynamic systems approaches may provide such a framework, using principles of self-organization to explain how novel forms emerge without predetermination and become increasingly complex with development. New trends in traditional theoretical families emphasize systemic, emergent processes, and these can now be explicated with principles of self-organization that apply to all natural systems. Self-organization thus provides a single explanation for the multiple facets of development, integrating diverse developmental viewpoints within a larger scientific perspective. Miller, P. H. (2009).

Journal of Abnormal Child Psychology, 36, 693-709. Demonstration of the transactional nature of development. Although much has been written about the utility of applying transactional models to the study of parenting practices, relatively few researchers have used such an approach to examine how children influence maternal wellbeing throughout their development. Using a sample of males from predominantly low-income families, the current study explored reciprocal relations between boys’ overt disruptive behavior (boys’ ages 5 to 10 years) and maternal depressive symptoms. The authors then examined this model with youthreported antisocial behaviors (ASB) and maternal depressive symptoms when the boys were older, ages 10 to 15. In middle childhood, evidence was found for both maternal and child effects from boys’ ages 5 to 6 using both maternal and alternative caregiver report of child aggressive behavior. In the early adolescence model, consistent maternal effects were found, and child effects were evident during the transition to adolescence (boys’ ages 11 to 12). The findings are discussed in reference to reciprocal models of child development and prevention efforts to reduce both maternal depression and the prevalence of child antisocial behavior.

Development and Psychopathology, 21, 889-912. Illustration of multifinality, resiliency, and multiple paths of development among maltreated children. This study investigated the longitudinal impact of maltreatment parameters on personality processes and maladjustment and prospective relationships between personality trajectory classes and subsequent maladjustment outcomes. The sample involved maltreated (n = 249) and nonmaltreated (n = 200) children followed longitudinally between ages 6 and 10. 19 Chapter 1 Introduction: Theories of Social Development Growth mixture modeling indicated multifinality in personality development depending on the risk status (i.e., maltreated vs. nonmaltreated). Two trajectory classes of ego resiliency were identified for maltreated children: those who showed a declining trajectory exhibited greater maladjustment. In contrast, three trajectory classes of ego control were identified for nonmaltreated children; the subgroups showing increases in ego undercontrol or dramatic changes from high ego undercontrol to high ego overcontrol exhibited poor adjustment. Experiencing multiple maltreatment subtypes and physical/sexual abuse were related to higher levels of ego undercontrol and externalizing symptomatology, whereas early onset of maltreatment was associated with the low and decreasing trajectory of ego resiliency and higher levels of internalizing symptomatology. The findings suggest that ego resiliency and ego control, personality processes related to self-regulation, may be important factors in identifying distinct pathways to later personality disorders as well as pathways to resilient functioning.

Social Psychology of Education, 11, 229-241. Demonstration of how context can influence perceptions and labeling of children’s behavior. This study investigated whether preservice teachers’ attitudes surrounding school grade labels influenced interpretations and recall of children’s classroom behavior using the automatic attitude activation model (Fazio, In R. M. Sorrentino & E. T. Higgins (Eds.), Handbook of motivation and cognition: Foundations of social behavior, 1986) as a theoretical framework. Participants were randomly assigned to one of three conditions: The expectation of viewing a video of children in schools labeled as “A,” “F,” or “typical” as a result of the school’s aggregated student performance on standardized tests. Results indicated that participants who believed that they were viewing a video of an “F” classroom recalled more negative and fewer positive behaviors compared to the “typical” classroom. Likewise, there was a trend for participants to recall more negative and fewer positive behaviors when viewing a video of an “F” compared to an “A” school. Therefore, negative attitudes about a school label of “F” biased preservice teachers’ perceptions and memories of children’s classroom behaviors. Phillips, L., & Cameron, C. A. (2012). Investigating the multimodality of children and youth. International Journal of Child, Youth and Family Studies, 2 & 3, 284–299. This article illustrates various ways of empirically testing transactional (Sameroff) and biosocial (Bronfenbrenner) models of development. Capturing lived childhoods without decontextualizing their meaning and still providing information needed by policy-makers and practitioners is a pressing challenge for contemporary researchers. In this paper the authors provide information to open up such a dialogue via a range of tools they have utilized when investigating well-being. They interrogate biosocio-ecological approaches to human development to provide relatively holistic pictures of the lived experience of childhood. They utilize various methods within this approach to determine what they transactionally facilitate at each level. At the biopsychological level, for example, controlled, psychologically valid, psychosocial stress procedures expose hormonal responses, yielding valuable information about individual differences in physiological stress reactivity. At the level of the psychological self within a social ecology, they systematically observe children and youth in naturalistic, environmental transactions with the aid of visual methods such as Day in the Life filming, and invite the children and their parents and youth to share their reflections on their 20 Chapter 1 Introduction: Theories of Social Development lived context via focused discussions and interviews. In this paper they discuss new ways of integrating research findings by suggesting Sameroff’s (2010) unified theory as an interpretive framework for research within the field of child and youth care. 21 Chapter 1 Introduction: Theories of Social Development Movies for Instructors Introduction: The Developing Person: Theories of Development (2003, Insight Media, 30 min.).

Darwin: The documentary film The Genius of Charles Darwin* (2008) includes segments on Darwin’s life and discoveries and an attempt to convince a group of school children that evolution explains the world better than religion. The movie Creation* (2009) focuses on 22 Chapter 1 Introduction: Theories of Social Development Darwin’s personal life during the time he was writing On the Origin of Species and reveals the struggles he went through balancing his religious faith with his science. Ethological theory: is illustrated in the short documentary Konrad Lorenz: Science of Animal Behavior* (1975). Lorenz’s work is also the basis for the movie Fly Away Home* (1996) in which a young girl becomes the “mother” to a flock of geese and has to teach them how to migrate south for the winter. How social development is influenced by environmental factors: NOVA: Secret of the Wild Child* (1997) is a documentary about Genie, the 13-year-old girl who was rescued from her home by social workers after a decade with virtually no human contact. How social development varies across neighborhoods and historical eras: Where Do the Children Play?* (2002) shows how children’s experiences depend on where and when they are born. The film opens by examining differences between growing up today and childhood as it was lived 50 years ago and examines how restrictive patterns of sprawl, congestion, and suburban development affect children’s development. How children’s experiences (and social development) differ in different cultures: Families of the World* (1997–2000), a documentary series illustrating cultural differences and similarities among children from Mexico, Japan, India, Egypt, China, Russia, France, the United States, and several other nations. Each film records two children performing their daily activities. Babies* (2010) is a visually stunning film that chronicles the lives of four infants—in Mongolia, Namibia, San Francisco, and Tokyo—from first breath to first steps. * Movies that are included in the “At the Movies” section in the Student Guide are marked with an asterisk. 23 Chapter 1 Introduction: Theories of Social Development Student Handout 1-1 Chapter Summary Social Development The field of social development includes descriptions of social behaviors, individual differences in social behavior, and changes in social behavior with age as well as explanations for these changes and differences. Social Development: A Brief History The scientific study of social development began with Darwin’s work in the 1800s. Subsequently, competing views were expressed in Watson’s behaviorally oriented theory, Freud’s biologically inspired theory, and Gesell’s maturational theory. Critical Questions about Social Development How do biological and environmental influences affect social development? Modern developmental psychologists recognize the importance of both biological and environmental influences and are concerned with discovering the ways in which these factors interact to produce developmental differences. What role do children play in their own development? Most developmental psychologists believe that children actively shape, control, and direct the course of their own development. What is the appropriate unit for studying social development? Although researchers have typically focused on individual children, they have increasingly recognized that other units such as dyads, triads, and social groups are also important. Is development continuous or discontinuous? Some theorists view social development as a continuous process whereby change takes place smoothly and gradually. Others see development as a series of qualitatively different stages or steps. The more closely we examine development, the more we see ebbs and flows in the acquisition of social skills. Is social behavior the result of the situation or the child? Most developmental psychologists stress the complementary roles of situational factors and child differences. Is social development universal across cultures? Most developmental psychologists agree that cultural contexts should be considered but believe that universal aspects of development such as emotions, language, and communication coexist with cultural variations. How does social development vary across historical eras? Both abrupt and gradual changes in society influence social development. Is social development related to other developmental domains? Social development influences and is influenced by emotional, cognitive, language, perceptual, and motor development. How important are mothers for children’s social development? Although mothers are clearly important in children’s social development, other people including fathers, siblings, grandparents, peers, teachers, and religious leaders also are important influences. Is there a single pathway for social development? Children may start out at a similar place but end up at very different points (multifinality), or they may follow different paths but end up at the same point (equifinality). 24 Chapter 1 Introduction: Theories of Social Development What influences how we label children’s social behavior? Three sets of factors— characteristics of the child, the adult, and the context—influence social judgments and, in turn, how social behaviors are labeled. Do developmental psychologists own social development? Scholars in a variety of fields including pediatrics, psychiatry, anthropology, economics, law, and history have made valuable contributions to the field of social development. Theoretical Perspectives on Social Development Theories help organize and integrate knowledge into a coherent account of how children develop and foster research by providing testable predictions about behavior. Historically, grand theories reflected attempts to account for all aspects of development. Modern theories tend to be more narrowly focused attempts to explain specific aspects of social development. Psychodynamic Perspective In Freud’s psychodynamic theory, basic biological drives motivate the child. Early experiences are essential for determining later behavior. Erikson expanded Freud’s theory to include social and cultural influences on development. His psychosocial theory is organized around a series of fundamental personal and social tasks that individuals must accomplish at each stage. Psychodynamic theories helped shape many concerns of modern social development, including the effects of early experience in the family and the psychological roots and importance of aggression, morality, gender roles, and attachment. However, the central claims of the theories are difficult to test empirically. Traditional Learning Perspective Traditional learning theories emphasize how new behaviors are acquired through a gradual and continuous process of learning. The theories had important applications and have been used in homes, schools, and clinics to reduce children’s behavior problems. Their lack of attention to developmental changes is a limitation. Cognitive Social Learning Theory Bandura focused attention on observational learning. The notions of reciprocal determinism and self-efficacy were important additions to this theoretical position. The lack of attention to developmental issues, the limited ecological validity of the findings, and the limited recognition of the roles of biology and culture are shortcomings of the theory. Social Information-Processing Theory This approach focuses on how children take in, use, and remember information to make decisions about social actions. The lack of developmental focus, the limited role allocated to emotion, and the heavy emphasis on deliberate decision making rather than automatic or habitual responding are limitations of this perspective. Cognitive Developmental Perspective In Piaget’s theory of development, children actively seek new experiences and from them construct mental structures. They assimilate new information into existing structures and accommodate structures when the information doesn’t fit. Piaget’s focus on stages has been 25 Chapter 1 Introduction: Theories of Social Development questioned, and his lack of emphasis on emotions, culture, and social behavior make his theory of limited use in the field of social development. Social Cognitive Domain Theory This perspective focuses on how children learn to make social judgments about their world. According to this approach, children’s social judgments are domain specific. Vygotsky’s Sociocultural Theory This theory focuses on the contributions of social and cultural factors to children’s development. Children grow and change as a function of their own efforts and the guidance of more skilled others. The theory does not describe how interactions change over the course of development. Systems Perspective According to systems theories, other elements or members of the system influence an individual’s behaviors. Bronfenbrenner’s ecological systems theory stresses the importance of relations between the child and environmental systems, such as the family, school, community, and culture. Development involves the interplay between the child and the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Lack of developmental focus as well as limited information about the processes that govern cross-level linkages are limitations of this theory. Biological Perspective Ethologists observe behaviors in natural settings and study patterns of behaviors across human and infrahuman species and across human societies and cultures. The theory is largely descriptive. Evolutionary psychology asserts that social behaviors reflect survival needs and processes of human evolution. It focused attention on parental investment as a way to ensure intergenerational continuity of genes and on the adaptive value of immaturity. A recent application of evolutionary developmental theory is “life history theory,” which suggests that the schedule of key events over the life course is influenced by natural selection to produce the largest possible number of surviving offspring and thus maximize the successful passing on of the organism’s genes. These key events include the age of sexual maturity and first reproduction, the number of offspring produced, and the level of parental investment in children. The approach has limited relevance for addressing issues associated with rapid changes. Many explanations are post hoc. Behavior genetics addresses the relative contributions of heredity and environment to social development and the interdependence between environmental conditions and whether and when genes are expressed in behavior. The particular genes or clusters of genes that account for social outcomes are still poorly understood, and the way in which the environment is measured is often very general. Life Span Theory This theory emphasizes development over the entire life course. Changes can be traced to normative age–graded events including entry into school, nonnormative events such as 26 Chapter 1 Introduction: Theories of Social Development divorce, and historical or cohort-related events such as the Great Depression or the Vietnam War. The impact of this perspective is limited by the fact that much of the theorizing has involved older adults. Variety of Theoretical Perspectives Social development can be approached from a variety of perspectives and it is often helpful to draw on several theories to explain children’s development. 27 Chapter 1 Introduction: Theories of Social Development Student Handout 1-2 Key Terms GLOSSARY TERMS age cohort People who were born in the same time period and share historical experiences. accommodation Modifying an existing schema to fit a new experience. assimilation Applying an existing schema to a new experience. chronosystem The time-based dimension that can alter the operation of all other systems in Bronfenbrenner’s model, from microsystem through macrosystem. classical conditioning A type of learning in which a new stimulus is repeatedly presented with a familiar stimulus until an individual learns to respond to the new stimulus in the same way as the familiar stimulus. cognitive social learning theory A theory that stresses the importance of observation and imitation in the acquisition of new behaviors, with learning mediated by cognitive processes. critical period A specific time in an organism’s development during which external factors have a unique and irreversible impact. desensitization Classical conditioning therapy used to overcome phobias and fears through exposure to increasingly intense versions of the feared stimulus. domain specificity Processes of development are different for different types of behavior, for example, moral judgments, manners, and peer relationships. drive reduction theory A version of learning theory suggesting that the association of stimulus and response in classical and operant conditioning results in learning only if it is accompanied by reduction of basic primary drives such as hunger and thirst. ecological theory A theory stressing the influences of environmental systems and the relations between the systems on development. ego In Freud’s theory, the rational component of the personality, which tries to satisfy needs through appropriate, socially acceptable behaviors. egocentric Tending to view the world from one’s own perspective and to have difficulty seeing things from another’s viewpoint.
