Find Balance!
Balance scientific research with real-world applications.
AGREE
example, a psychologist interviewed by Ted Koppel on Nightline
may have certain values concerning government’s responsibility
in caring for the homeless, parents’ responsibility in an adolescent’s use of cocaine, and the responsibility of an individual with
a psychological disorder who has committed mass murder.
Psychotherapists whom people consult about problems
may have certain personal values concerning self-esteem, marriage, sexual conduct, and other topics that influence the advice
they give. For example, one psychotherapist might perceive a
client’s sexual behavior as “sick,” whereas another might think
of it as an adaptive sexual variation.
Psychology professors have certain values about gender,
moral behavior, religion, child rearing, and how to get ahead in
life that might influence what they communicate in their lectures and how they respond to students’ questions. For example, one professor might perceive that a female’s assertive
behavior is too aggressive, whereas another might think of the
behavior as competent.
But wait a minute. Isn’t psychology supposed to be an objective science? As a science, psychology is dedicated to discovering facts about behavior and creating theories to explain
those facts. In this description, there is no mention of values.
The scientific approach requires only that psychology discover
the most dependable facts and generate the best theories possible (Kimble, 1989). In the pure world of science, there is no
place for values. Some critics, though, question whether a view
of science as value-free is realistic (Seligman, Olson, & Zanna,
1996). They argue that—although psychologists often strive to
2.0seek to discover facts about

behavior—in the court of life, which is psychology’s setting,
values and psychology are sometimes difficult to disentangle.
DISAGREE
1. Human beings are basically good.
2. By changing the environment,
you can change people’s behavior.
3. Intelligence is the most important
human trait.
4. People are too concerned about
themselves.
5. Physical attraction is important
in choosing a mate.
6. Women are becoming too
assertive.
7. Divorce is wrong.
8. Religion is not an appropriate
area of study for psychologists.
9. Money can bring happiness.
10. It is okay to cheat if you don’t
get caught.
The way you responded to these items provides insight into
your values. If you decide to become a psychologist, might your
views on these topics, as well as others, influence the area you
choose to research? Might psychologists’ values influence how
they respond in a media interview? Might clinical psychologists’ values affect the advice they give to clients? Might psychology professors’ values influence the topics they choose to
discuss in class and how they respond to students’ questions?
In some cases, researchers’ values might influence their
choice of research questions. A divorced woman might decide
to study the inadequate involvement and support of noncustodial fathers in their children’s lives rather than the increased
role of fathers in caring for children because of her soured relationship with her ex-husband. An Asian American might
choose to study the importance of conformity to a group’s goals
rather than an individual’s unique contributions to a project
because he or she believes that getting along with others in a
group is more important than an individual’s achievement.
When psychologists are called on as experts, they may make
statements and recommendations that are laden with values. For

You are in a large lecture hall. The instructor is speaking too softly and you know
other students are having trouble hearing what is being said.
You want to start a conversation at a gathering, but you don’t know anyone there.
You are sitting next to someone who is smoking, and the smoke bothers you.
You are talking to someone about something that is important to you, but he or she

You are speaking and someone interrupts you.
You receive an unjust criticism from someone.
In most circumstances, being assertive is the best strategy. However, there may
be some situations in which a different style of interaction is needed. Look at each situation again and determine if the assertive style is always the best strategy and
whether there is any circumstance in which one of the other styles might work best.

Industrial and Organizational Psychology Industrial and organizational psychology (I/O psychology) centers on the workplace, both on the workers and on
the organizations that employ them. I/O psychology is often partitioned into industrial psychology and organizational psychology. Industrial psychology involves personnel and human resource management. Industrial psychology is increasingly
referred to as personnel psychology. Organizational psychology examines the social
and group influences of the organization (Goldstein & Ford, 2002; Muchinsky,
2003).

that occurs through experience. Observational learning
is learning by watching what other people do. In associative learning, a connection is made between two events.
Conditioning is the process by which associative learning
occurs. In classical conditioning, organisms learn the association between two stimuli and, in operant conditioning, they learn the association between behavior and a
consequence.

What is classical conditioning?
It is a nice spring day. A father takes his baby out for a walk. The baby reaches over
to touch a pink flower and is stung by the bumblebee sitting on the petals. The next
day, the baby’s mother brings home some pink flowers. She removes a flower from
the arrangement and takes it over for her baby to smell. The baby cries loudly as
soon as she sees the pink flower. The baby’s panic at the sight of the pink flower
illustrates the learning process of classical conditioning, in which a neutral stimulus (the flower) becomes associated with a meaningful stimulus (the pain of a bee
sting) and acquires the capacity to elicit a similar response (fear).
Pavlov’s Studies
In the early 1900s, the Russian physiologist Ivan Pavlov was interested in the way the
body digests food. In his experiments, he routinely placed meat powder in a dog’s mouth,
causing the dog to salivate. Pavlov noticed that the meat powder was not the only stimulus that caused the dog to salivate. The dog salivated in response to a number of stimuli associated with the food, such as the sight of the food dish, the sight of the individual
who brought the food into the room, and the sound of the door closing when the food
arrived. Pavlov recognized that the dog’s association of these sights and sounds with the
food was an important type of learning, which came to be called classical conditioning.
Pavlov (the white-bearded gentleman in
the center) is shown demonstrating the
nature of classical conditioning to students at the Military Medical Academy in
Russia.

Apply Your Knowledge
1. One common association that people have is called a conditioned taste aversion, which occurs when you eat or drink
something and then get sick. A conditioned taste aversion is
most likely to occur when the food or drink is something
that is relatively unfamiliar. Suppose that you have acquired
a conditioned taste aversion to tequila. Identify what the unconditioned stimulus, unconditioned response, conditioned
stimulus, and conditioned response are in this example.
2. Positive and negative reinforcement are often difficult concepts to understand. On the following website, examples
and a practice exercise may help you figure out the distinction more easily:

becomes associated with a meaningful stimulus and
comes to elicit a similar response. Pavlov discovered that
an organism learns the association between an unconditioned stimulus (UCS) and a conditioned stimulus (CS).
The UCS automatically produces the unconditioned response (UCR). After conditioning (CS-UCS pairing), the
CS elicits the conditioned response (CR) by itself. Acquisition in classical conditioning is the initial linking of
stimuli and responses, which involves a neutral stimulus
being associated with the UCS so that the CS comes to
elicit the CR. Two important aspects of acquisition are
contiguity and contingency/predictability. Generalization in classical conditioning is the tendency of a new
stimulus that is similar to the original conditioned stimulus to elicit a response that is similar to the conditioned
response. Discrimination in classical conditioning is the
process of learning to respond to certain stimuli and not
to others. Extinction in classical conditioning is the
weakening of the CR in the absence of the UCS. Spontaneous recovery is the recurrence of a CR after a time delay without further conditioning.
• In humans, classical conditioning has been applied to explaining and eliminating fears. Counterconditioning, a
classical conditioning procedure for weakening the CR
by associating the fear-provoking stimulus with a new
response that is incompatible with the fear, has been successful in eliminating fears. Classical conditioning also
can explain pleasant emotions. Some of the behaviors

bility of the behavior’s occurrence. B. F. Skinner described
the behavior of the organism as operant: The behavior
operates on the environment, and the environment in
turn operates on the organism. Whereas classical conditioning involves respondent behavior, operant conditioning involves operant behavior. In most instances,
operant conditioning is better at explaining voluntary
behavior than classical conditioning is.
Thorndike’s law of effect states that behaviors followed
by positive outcomes are strengthened, whereas behaviors followed by negative outcomes are weakened.
Thorndike’s view that the organism’s behavior is due to
a connection between a stimulus and a response is called
S-R theory.
Skinner believed that the mechanisms of learning are
the same for all species. This led him to study lower animals extensively in the hope that the basic mechanisms
of learning could be more easily understood in organisms simpler than humans. Like Skinner, contemporary
behaviorists study organisms under precisely controlled
conditions so that the connection between the operant
behavior and the specific consequences can be examined
in minute detail.
Shaping is the process of rewarding approximations of
desired behavior in order to shorten the learning process.
Principles of reinforcement include the distinction between positive reinforcement (the frequency of a behavior
increases because it is followed by a rewarding stimulus)
and negative reinforcement (the frequency of behavior
increases because it is followed by the removal of an
aversive, or unpleasant, stimulus). Positive reinforcement
can be classified as primary reinforcement (using reinforcers that are innately satisfying) and secondary reinforcement (using reinforcers that acquire positive value
through experience). Reinforcement can also be continuous (a behavior is reinforced every time) or partial (a
behavior is reinforced only a portion of the time). Schedules of reinforcement—fixed-ratio, variable-ratio, fixedinterval, and variable-interval—are timetables that
determine when a behavior will be reinforced. Operant
conditioning involves generalization (giving the same response to similar stimuli), discrimination (responding to
stimuli that signal that a behavior will or will not be reinforced), and extinction (a decreasing tendency to
perform a previously reinforced behavior when reinforcement is stopped). Punishment is a consequence that
decreases the likelihood a behavior will occur. Punishment, through which a behavior is weakened, is different from negative reinforcement, through which a
behavior is strengthened. In positive punishment, a
behavior decreases when it is followed by an unpleasant
stimulus. In negative punishment, a behavior decreases
when a positive stimulus is removed from it. Time-out is

Chapter 7 Learning
Classical conditioning also can be involved in immune system functioning, which
is important for producing antibodies to ward off disease and illness, such as AIDS
and the flu. Robert Ader and Nicholas Cohen (Ader, 2000; Ader & Cohen, 1975,
2000) have conducted a number of studies that reveal that classical conditioning can
produce immunosuppression (a decrease in the production of antibodies). The initial
discovery of this link between classical conditioning and immunosuppression came
as a surprise. In the course of studying Pavlovian conditioning, Ader (1974) was
examining how long a conditioned response would last in some laboratory rats. A
conditioned stimulus (saccharin solution) was paired with an unconditioned stimulus, a drug called Cytoxan, which induces nausea. Afterward, while giving the rats
saccharin-laced water without the accompanying Cytoxan, Ader watched to see how
long it would take the rats to forget the association between the two.
Unexpectedly, in the second month of the study, the rats developed a disease and
began to die off. In analyzing the unforeseen result, Ader checked out the properties
of the nausea-inducing drug he had used. He discovered that one of its side effects
was immunosuppression. Thus it turned out that the rats had been classically conditioned to associate sweet water not only with nausea but also with the shutdown of
the immune system. The sweet water apparently had become a CS for immunosuppression. Researchers have found that conditioned immune responses also may occur
in humans (Ader, 2000; Voudouris, Peck, & Coleman, 1985).

Applying Classical Conditioning: Consumer Psychology Consumer psychology is
the study of how consumers think, feel, reason, and select between different alternatives, such as brands and products. Many contemporary advertisers use classical
conditioning in some way (Perner, 2001). Consider this sequence:
• Beautiful woman (UCS) → emotional arousal (UCR) in males
• Beautiful woman (UCS) paired with an automobile (not yet a CS) many times
• Automobile (CS) → emotional arousal (CR)
In-Psych Plus
Recent research has shown that, if the conditioned stimulus is encountered outside of ads, it doesn’t predict the UCS (Bettman, 2001). Thus classical conditioning
may work best for infrequently encountered products and cases in which the UCS is
associated with only one brand. Also, classical conditioning usually works best when
the CS precedes the UCS in ads.
Not all commercials involve classical conditioning. Some just give information
about the product. The next time you watch TV, observe which ads rely on classical
conditioning. To review the elements of classical conditioning and its applications to
human learning, go to the interactivity “Classical Conditioning 2.”

Preface
Since I started teaching psychology in 1967, my motivation
and love for introducing students to this relevant science have
not wavered. This commitment to relevance and to science
not only has been a foundation of my teaching, but it is also
the heart of this book. In this edition, I’ve kept the theme of
psychology as a relevant science and, in line with current
trends in the discipline, increased the emphasis on the biological aspects of psychology and on the positive changes psychology can help us achieve in our lives. These themes,
together with a stronger focus on the key ideas in psychology,
are the main features of this update of Psychology.
New! Media Integration
References to video clips and interactivities, all drawn from
various McGraw-Hill media resources and chosen for their
interest and relevancy to the main content, appear within
the main text. The In-Psych Plus CD-ROM marginal icon provides an additional, visual reference to the media. Each
video and interactivity that is mentioned in the text appears
on the In-Psych Plus CD-ROM, which is packaged free with
the text. In addition, pedagogy, activities, test questions, and
other features have been created to complement these
video clips and reinforce students’ grasp of the key concepts
they illustrate. These materials are found on the In-Psych
Plus CD-ROM, in the Study Guide, in the Instructor’s
Course Planner, and in the Test Item Files.
Psychology: The Relevant Science
Many students come into the introductory psychology
class asking why they should study psychology when their
major is physics or computer science or French. To a psychologist, the answer is obvious: It will help you to understand yourself and others better. Psychology is relevant to
almost every aspect of daily life. What psychologists have
learned from memory research, for example, can be used
to study more effectively, no matter what the subject is.
Principles of learning can be applied to change undesirable
behavior in children. Knowledge of sensation and perception can be used to more effectively design computers. Research on stress, coping, and health can help people to live
fuller, happier lives.
Writing the preface for Psychology, I am convinced that
the science of psychology is more relevant today than
ever. After September 11, 2001, psychologists and psychiatrists were called on to counsel not only people whose
lives were directly affected by the attacks on the World
Trade Center and the Pentagon but also students, teachers,
parents, and others who were struggling to understand, as
we were, what could trigger such hostility and violence
toward Americans. Psychology teaches us about the roots
of aggression and the influence of groups on individual
behavior. It also suggests strategies for handling stress,
whatever the source. Nothing is more relevant to contemporary life.
In addition to relevance, this edition continues to
stress the scientific nature of the discipline. A hallmark of
the book has always been its focus on research, the foundation of all sciences. Here the latest research findings are
discussed, along with the classic studies that established
psychology as an objective science. There are more than
900 citations from the twenty-first century, including
many from 2002 through 2004. Also, numerous new
graphs show students how scientific data can be presented
visually.
Neuroscience and Biological
Influences on Behavior
The growing emphasis on neuroscience and genetics as the
means to understand the effects of biology on behavior is
also reflected in this edition. Evolutionary psychology, another area of increasing interest, receives increased attention as well. Knowing that students often have difficulty
understanding why it is important to learn biology in a
course on psychology, I’ve taken particular care to present
these topics in a psychological context and to underscore the complex relationship between biology, environment, and behavior wherever appropriate. Neuroscientist
Lawrence Cauller provided outstanding guidance for incorporating stronger biological neuroscience content in
this edition.
Positive Psychology
Currently, there is a movement in psychology to focus attention on the positive contributions psychology can make
to everyday life. Proponents of positive psychology, notably
Mihaly Csikszentmihalyi, share the belief that for much of
xvii
spy7fmpgi_xxv.qxd 3/26/04 11:29 AM Page xviii impos03 303:mhspy7u:spy7fm:layouts:
xviii
Preface
the twentieth century the discipline concentrated on the
negative aspects of life and that it’s time to emphasize the
positive side of psychology. Positive psychology offers all of
us the opportunity to take control of our lives and find balance. For this edition, I have revised many of the chapteropening vignettes and examples in the text to highlight
positive outcomes and, with Csikszentmihalyi’s expert guidance, have incorporated material on positive psychology
throughout the book.
Focus on Key Ideas
The most significant instructional challenge facing introductory psychology teachers today is ensuring that students
master the core content of the course. For students overwhelmed by information from lectures, textbooks, the Internet, and other media, it is more difficult than ever to find
the main ideas in their courses. To address these challenges
and help students achieve the best possible outcome, I have
developed a learning system for this edition that emphasizes
basic concepts and ideas, encourages review, and promotes
critical thinking. This system frames the presentation in the
text and the supplements, providing a truly integrated package that reinforces learning and gives instructors the tools
they need to assess students’ grasp of core concepts and
ideas.
The learning system has several components, all centered on three to six key ideas per chapter. These ideas are
encapsulated in learning goals, which correspond with the
chapter’s main headings, as shown at the opening of each
chapter. The learning goals reappear at several places in the
chapter: as a question at the beginning of a new topic, in a
guided review at the end of the section, and again in a summary at the end of the chapter. Content maps of the section
and subsection headings accompany the learning goal question at the beginning of each major section. Together with a
complete chapter map at the end of the chapter, the section
maps provide a visual guide to the core concepts that support the learning goals.
To encourage students to apply what they’ve learned,
and increase the likelihood that they will remember the material, the learning system includes critical thinking questions keyed to the learning goals in the “Review and
Sharpen Your Thinking” sections. Additionally, “What do
you think?” exercises accompany each of the new Critical
Controversy boxes and at least three critical thinking exercises follow the review section at the end of each chapter in
a section titled“Apply Your Knowledge.” For students who
have access to the Web, the end-of-chapter exercises include
at least one Web-based activity.
Incorporating the learning goals and maps in the student supplements reinforces the lessons from the text and
eliminates the confusion many students have about how to
use the supplements to boost their performance in the
course.
Changes in Coverage
Instructors who have used previous editions of this text will
find much in the seventh edition that’s different and much
that hasn’t changed. In addition to increased emphasis on
neuroscience, genetics, evolutionary psychology, and positive psychology, the seventh edition contains increased coverage of diversity, controversies, and careers in psychology.
This material is presented where appropriate throughout
the book.
The table of contents and chapter sequence remain the
same as in the sixth edition, except that human development
now falls closer to the beginning of the book (chapter 4). With
this change, instructors can cover a topic of high student
interest early in the course, while the principles of genetics
(chapter 3) are still fresh in students’ minds, and later
incorporate the material in their discussions of learning,
cognition, and language.
Although the number of chapters and their topics are
unchanged, the substance and presentation in each chapter
have been revised thoroughly. Some of the detail that is less
relevant today than it once was has been pruned to make
room for cutting-edge research and some of the presentation was reconceptualized to focus on the key ideas reflected
in the learning goals. Although there isn’t enough space
here to list all of the changes in this edition, here are the
highlights:
CHAPTER 1
