Social Ecological Model www.AssignmentPoint.com www.AssignmentPoint.com Socio-ecological models were developed to further the understanding of the dynamic interrelations among various personal and environmental factors. Socioecological models were introduced to urban studies by sociologists associated with the Chicago School after the First World War as a reaction to the narrow scope of most research conducted by developmental psychologists. These models bridge the gap between behavioral theories that focus on small settings and anthropological theories that analyze larger settings. Introduced as a conceptual model in the 1970s, formalized as a theory in the 1980s, and continually revised by Bronfenbrenner until his death in 2005, Urie Bronfenbrenner's Ecological Framework for Human Development applies socioecological models to human development. In his initial theory, Bronfenbrenner postulated that in order to understand human development, the entire ecological system in which growth occurs needs to be taken into account. In subsequent revisions, Bronfenbrenner acknowledged the relevance of biological and genetic aspects of the person in human development. From systems thinking to socioecological models A system can be defined as a comparatively bounded structure consisting of interacting, interrelated, or interdependent elements that form a whole. Systems thinking argues that the only way to fully understand something or an occurrence is to understand the parts in relation to the whole. Thus, systems thinking, which is the process of understanding how things influence one another within a whole, is central to ecological models. Generally, a system is a community situated within an environment. Examples of systems are health systems, education systems, food systems, and economic systems. www.AssignmentPoint.com Drawing from natural ecosystems which are defined as the network of interactions among organisms and between organisms and their environment, social ecology is a framework or set of theoretical principles for understanding the dynamic interrelations among various personal and environmental factors. Social ecology pays explicit attention to the social, institutional, and cultural contexts of people-environment relations. This perspective emphasizes the multiple dimensions (example: physical environment, social and cultural environment, personal attributes), multiple levels (example: individuals, groups, organizations), and complexity of human situations (example: cumulative impact of events over time). Social ecology also incorporates concepts such as interdependence and homeostasis from systems theory to characterize reciprocal and dynamic person-environment transactions. Individuals are key agents in ecological systems. From an ecological perspective, the individual is both a postulate (a basic entity whose existence is taken for granted) and a unit of measurement. As a postulate, an individual has several characteristics. First he requires access to an environment, upon which he/she is dependent for knowledge. Second, he is interdependent with other humans; that is, is always part of a population and cannot exist otherwise. Third, he is time bound, or has a finite life cycle. Fourth, he has an innate tendency to preserve and expand life. Fifth, he has capacity for behavioral variability. Social ecological models are thus applicable to the processes and conditions that govern the lifelong course of human development in the actual environment in which human beings live. Urie Bronfenbrenner's Ecological Framework for Human Development is considered to be the most recognized and utilized social ecological model (as applied to human development). Ecological systems theory www.AssignmentPoint.com considers a child's development within the context of the systems of relationship that form his or her environment. Bronfenbrenner's ecological framework for human development Bronfenbrenner's ecological framework for human development was first introduced in the 1970s as a conceptual model and became a theoretical model in the 1980s. Two distinct phases of the theory can be identified. Bronfenbrenner[8] stated that "it is useful to distinguish two periods: the first ending with the publication of the Ecology of Human Development (1979), and the second characterized by a series of papers that called the original model into question." Bronfenbrenner's initial theory illustrated the importance of place to aspects of the context, and in the revision, he engaged in self-criticism for discounting the role a person plays in his or her own development while focusing too much on the context. Although revised, altered, and extended, the heart of Bronfenbrenner's theory remains the ecological-stressing personcontext interrelatedness. Ecological systems theory In his original theory, Bronfenbrenner postulated that in order to understand human development, the entire ecological system in which growth occurs needs to be taken into account. This system is composed of five socially organized subsystems that support and guide human development. Each system depends on the contextual nature of the person's life and offers an evergrowing diversity of options and sources of growth. Furthermore, within and between each system are bi-directional influences. These bi-directional influences imply that www.AssignmentPoint.com relationships have impact in two directions, both away from the individual and towards the individual. Because we potentially have access to these subsystems we are able to have more social knowledge, an increased set of possibilities for learning problem solving, and access to new dimensions of self-exploration. Microsystem The microsystem is the layer closest to the child and contains the structures with which the child has direct contact. The microsystem encompasses the relationships and interactions a child has with his or her immediate surroundings such as family, school, neighborhood, or childcare environments. At the microsystem level, bi-directional influences are strongest and have the greatest impact on the child. However, interactions at outer levels can still impact the inner structures. This core environment stands as the child's venue for initially learning about the world. As the child's most intimate learning setting, it offers him or her a reference point for the world. The microsystem may provide the nurturing centerpiece for the child or become a haunting set of memories. The real power in this initial set of interrelations with family for the child is what they experience in terms of developing trust and mutuality with their significant people. The family is the child's early microsystem for learning how to live. The caring relations between child and parents (or other caregivers) can help to influence a healthy personality. For example, the attachment behaviors of parents offer children their first trust-building experience. Mesosystem www.AssignmentPoint.com The mesosystem moves us beyond the dyad or two-party relation. Mesosystems connect two or more systems in which child, parent and family live. Mesosystems provide the connection between the structures of the child's microsystem. For example, the connection between the child's teacher and his parents, between his church and his neighborhood, each represent mesosystems. Exosystem The exosystem defines the larger social system in which the child does not directly function. The structures in this layer impact the child's development by interacting with some structure in his/her microsystem. Parent workplace schedules or community-based family resources are examples. The child may not be directly involved at this level, but they do feel the positive or negative force involved with the interaction with their own system. The main exosystems that indirectly influence youth through their family include: school and peers, parents' workplace, family social networks and neighborhood community contexts, local politics and industry. Exosystems can be empowering (example: a high quality child-care program that benefits the entire family) or they can be degrading (example: excessive stress at work impacts the entire family). Furthermore, absence from a system makes it no less powerful in a life. For example, many children realise the stress of their parent's workplaces without ever physically being in these places. Macrosystem The macrosystem is composed of cultural values, customs and laws. It refers to the overall patterns of ideology and organization that characterize a given society or social group. Macrosystems can be used to describe the cultural or www.AssignmentPoint.com social context of various societal groups such as social classes, ethnic groups, or religious affiliates. This layer is the outermost layer in the child's environment. The effects of larger principles defined by the macrosystem have a cascading influence throughout the interactions of all other layers. The macrosystem influences what, how, when and where we carry out our relations. For example, a program like Women, Infants, and Children (WIC) may positively impact a young mother through health care, vitamins, and other educational resources. It may empower her life so that she, in turn, is more affective and caring with her newborn. In this example, without an umbrella of beliefs, services, and support for families, children and their parents are open to great harm and deterioration. In a sense, the macrosytem that surrounds us helps us to hold together the many threads of our lives. Chronosystem The chronosystem encompasses the dimension of time as it relates to a child's environment. Elements within this system can be either external, such as the timing of a parent's death, or internal, such as the physiological changes that occur with the aging of a child. Family dynamics need to be framed in the historical context as they occur within each system. Specifically, the powerful influence that historical influences in the macrosystem have on how families can respond to different stressors. Bronfenbrenner suggests that, in many cases, families respond to different stressors within the societal parameters existent in their lives. www.AssignmentPoint.com
