1.1 INTRODUCTION: What Is Psychology?

KEY THEME

Today, psychology is defined as the science of behavior and mental processes, a definition that reflects psychology’s origins and history.

KEY QUESTIONS

MYTH !lhtriangle! SCIENCE

Is it true that the field of psychology primarily focuses on treating people with psychological problems and disorders?

Psychology is formally defined as the scientific study of behavior and mental processes. But this definition is deceptively simple. As you’ll see in this chapter, the scope of contemporary psychology is very broad—ranging from the behavior of a single brain cell to the behavior of a crowd of people or even entire cultures.

Many people think that psychologists are primarily—or even exclusively—interested in studying and treating psychological disorders and problems. But as this chapter will also show, psychologists are just as interested in “normal,” everyday behavior and mental processes—such as learning and memory, emotion and thought, relationships and loneliness. And, psychologists seek ways to use the knowledge that they discover through scientific research to optimize human performance and potential in many different fields, from classrooms to offices to the military.

The four basic goals of psychology are to describe, predict, explain, and control or influence behavior and mental processes. To illustrate how these goals guide psychological research, think about our classroom discussion. Most people, like Jenna, have an intuitive understanding of what the word “stress” refers to. Psychologists, however, seek to go beyond intuitive or “common sense” understandings of human experience.

       Here’s how psychology’s goals might help guide research on stress:

Aristotle (384–322 bce) The first Western thinker to study psychological topics, Aristotle combined the logic of philosophy with empirical observation. His best-known psychological work, De Anima, is regarded as the first systematic treatise on psychology. Its topics included such basic psychological processes as the senses, perception, memory, thinking, and motivation. Aristotle’s writings on psychology anticipated topics and theories that would be central to scientific psychology centuries later.

  1. Describe: Trying to objectively describe the experience of stress, Dr. Garcia studies the sequence of emotional responses that occur during stressful experiences.

  2. Predict: Dr. Kiecolt investigates responses to different kinds of challenging events, hoping to be able to predict the kinds of events that are most likely to evoke a stress response.

  3. Explain: Seeking to explain why some people are more vulnerable to the effects of stress than others, Dr. Lazarus studies the different ways that people respond to natural disasters.

  4. Control or Influence: After studying the effectiveness of different coping strategies, Dr. Folkman helps people use those coping strategies to better control their reactions to stressful events.

How did psychology evolve into today’s diverse and rich science? We begin this introductory chapter by stepping backward in time to describe the early origins of psychology and its historical development. As you become familiar with how psychology began and developed, you’ll have a better appreciation for how it has come to encompass such diverse subjects. Indeed, the early history of psychology is the history of a field struggling to define itself as a separate and unique scientific discipline. The early psychologists debated such fundamental issues as:

These debates helped set the tone of the new science, define its scope, and set its limits. Over the past century, the shifting focus of these debates has influenced the topics studied and the research methods used.

Possible sample answer: Psychology is formally defined as the scientific study of behavior and mental processes. The four major goals of psychology are to describe experience and behavior, predict events that cause behavior, explain why behavior occurs, and to control/influence of behavior.

Psychology’s Origins: THE INFLUENCE OF PHILOSOPHY AND PHYSIOLOGY

The earliest origins of psychology can be traced back several centuries to the writings of the great philosophers. More than 2,000 years ago, the Greek philosopher Aristotle wrote extensively about topics like sleep, dreams, the senses, and memory. Many of Aristotle’s ideas remained influential until the beginnings of modern science in the seventeenth century (Kheriaty, 2007).

At that time, the French philosopher René Descartes (1596–1650) proposed a doctrine called interactive dualism—the idea that mind and body were separate entities that interact to produce sensations, emotions, and other conscious experiences. Today, psychologists continue to explore the relationship between mental activity and the brain.

Nature or Nurture? Both father and daughter are clearly enjoying the experience of drawing together. Is the child’s interest in art an expression of her natural tendencies, or is it the result of her father’s encouragement and teaching? Originally debated by philosophers hundreds of years ago, the relationship between heredity and environmental factors continues to interest psychologists today.

Philosophers also laid the groundwork for another issue that would become central to psychology, the nature–nurture issue. For centuries, philosophers debated which was more important: the inborn nature of the individual or the environmental influences that nurture the individual. This debate was sometimes framed as nature versus nurture. Today, however, psychologists understand that “nature” and “nuture” are impossible to completely disentangle (Sameroff, 2010). So, while some psychologists do investigate the relative influences of heredity versus environmental factors on behavior, today’s researchers also focus on studying the dynamic interaction between environmental factors and genetic heritage (Meaney, 2010; Szyf, 2013).

Such philosophical discussions influenced the topics that would be considered in psychology. But the early philosophers could advance the understanding of human behavior only to a certain point. Their methods were limited to intuition, observation, and logic.

The eventual emergence of psychology as a science hinged on advances in other sciences, particularly physiology. Physiology is a branch of biology that studies the functions and parts of living organisms, including humans. In the 1600s, physiologists were becoming interested in the human brain and its relation to behavior. By the early 1700s, it was discovered that damage to one side of the brain produced a loss of function in the opposite side of the body. By the early 1800s, the idea that different brain areas were related to different behavioral functions was being vigorously debated. Collectively, the early scientific discoveries made by physiologists were establishing the foundation for an idea that was to prove critical to the emergence of psychology—namely, that scientific methods could be applied to answering questions about behavior and mental processes.

Possible sample answer: For centuries, philosophers debated which was more important: the inborn nature of the individual or the environmental influences that nurture the individual. Today, some psychologists still study the influences of heredity vs. environment on behavior. However, most psychologists now study the interaction between heredity and the environment and how both are involved in behavior as it is impossible to study one without the examining the influence of the other.

Wilhelm Wundt: THE FOUNDER OF PSYCHOLOGY

Wilhelm Wundt (1832–1920) German physiologist Wilhelm Wundt is generally credited as being the founder of psychology as an experimental science. In 1879, he established the first psychology research laboratory. By the early 1900s, Wundt’s research had expanded to include such topics as cultural psychology and developmental psychology (Wong, 2009).
Bettmann/Corbis

By the second half of the 1800s, the stage had been set for the emergence of psychology as a distinct scientific discipline. The leading proponent of this idea was a German physiologist named Wilhelm Wundt (Gentile & Miller, 2009). Wundt used scientific methods to study fundamental psychological processes, such as mental reaction times in response to visual or auditory stimuli. For example, Wundt tried to measure precisely how long it took a person to consciously detect the sight and sound of a bell being struck.

A major turning point in psychology occurred in 1874, when Wundt outlined the connections between physiology and psychology in his landmark text, Principles of Physiological Psychology (Diamond, 2001). He also promoted his belief that psychology should be established as a separate scientific discipline that would use experimental methods to study mental processes. A few years later, in 1879, Wundt realized that goal when he opened the first psychology research laboratory at the University of Leipzig. Many regard this event as marking the formal beginning of psychology as an experimental science (Kohls & Benedikter, 2010).

Wundt defined psychology as the study of consciousness and emphasized the use of experimental methods to study and measure consciousness. Until he died in 1920, Wundt exerted a strong influence on the development of psychology as a science (Wong, 2009). Two hundred students from around the world traveled to Leipzig to earn doctorates in experimental psychology under Wundt’s direction. Over the years, some 17,000 students attended Wundt’s afternoon lectures on general psychology, which often included demonstrations of devices he had developed to measure mental processes (Blumenthal, 1998).

Edward B. Titchener: STRUCTURALISM

Edward B. Titchener (1867–1927) In contrast to the psychology programs at both Harvard and Columbia Universities at the time, Edward Titchener welcomed women into his graduate program at Cornell. In fact, more women completed their psychology doctorates under Titchener’s direction than under any other male psychologist of his generation (Evans, 1991).

One of Wundt’s most devoted students was a young Englishman named Edward B. Titchener. After earning his doctorate in Wundt’s laboratory, Titchener began teaching at Cornell University in New York. There he established a psychology laboratory that ultimately spanned 26 rooms.

Titchener shared many of Wundt’s ideas about the nature of psychology. Eventually, however, Titchener developed his own approach, which he called structuralism. Structuralism became the first major school of thought in psychology. Structuralism held that even our most complex conscious experiences could be broken down into elemental structures, or component parts, of sensations and feelings. To identify these structures of conscious thought, Titchener trained subjects in a procedure called introspection. The subjects would view a simple stimulus, such as a book, and then try to reconstruct their sensations and feelings immediately after viewing it. (In psychology, a stimulus is anything perceptible to the senses, such as a sight, sound, smell, touch, or taste.) They might first report on the colors they saw, then the smells, and so on, in the attempt to create a total description of their conscious experience (Titchener, 1896).

structuralism

Early school of psychology that emphasized studying the most basic components, or structures, of conscious experiences.

In addition to being distinguished as the first school of thought in early psychology, Titchener’s structuralism holds the dubious distinction of being the first school to disappear. With Titchener’s death in 1927, structuralism as an influential school of thought in psychology essentially ended. But even before Titchener’s death, structuralism was often criticized for relying too heavily on the method of introspection.

As noted by Wundt and other scientists, introspection had significant limitations. First, introspection was an unreliable method of investigation. Different subjects often provided very different introspective reports about the same stimulus. Even subjects well trained in introspection varied in their responses to the same stimulus from trial to trial.

Second, introspection could not be used to study children or animals. Third, complex topics, such as learning, development, mental disorders, and personality, could not be investigated using introspection. In the end, the methods and goals of structuralism were simply too limited to accommodate the rapidly expanding interests of the field of psychology.

William James: FUNCTIONALISM

William James (1842–1910) Harvard professor William James was instrumental in establishing psychology in the United States. In 1890, James published a highly influential text, Principles of Psychology. James’s ideas became the basis of another early school of psychology, called functionalism, which stressed studying the adaptive and practical functions of human behavior.
Bettmann/Corbis
Charles Darwin (1809–1882) Naturalist Charles Darwin had a profound influence on the early development of psychology. Darwin was not the first scientist to propose that complex organisms evolved from simpler species (Caton, 2007). However, Darwin’s book, On the Origin of Species, published in 1859, gathered evidence from many different scientific fields to present a compelling account of evolution through the mechanism of natural selection. Darwin’s ideas have had a lasting impact on scientific thought (Dickins, 2011; Pagel, 2009).

By the time Titchener arrived at Cornell University, psychology was already well established in the United States. The main proponent of American psychology was one of Harvard’s most outstanding teachers—William James. James had become intrigued by the emerging science of psychology after reading one of Wundt’s articles. But there were other influences on the development of James’s thinking.

Like many other scientists and philosophers of his generation, James was fascinated by the idea that different species had evolved over time (Menand, 2001). Many nineteenth-century scientists in England, France, and the United States were evolutionists—that is, they believed that species had not been created once and for all but had changed over time (Caton, 2007).

In the 1850s, British philosopher Herbert Spencer had published several works arguing that modern species, including humans, were the result of gradual evolutionary change. In 1859, Charles Darwin’s groundbreaking work, On the Origin of Species, was published. James and his fellow thinkers actively debated the notion of evolution, which came to have a profound influence on James’s ideas (Richardson, 2006). Like Darwin, James stressed the importance of adaptation to environmental challenges.

In the early 1870s, James began teaching a physiology and anatomy class at Harvard University. An intense, enthusiastic teacher, James was prone to changing the subject matter of his classes as his own interests changed (B. Ross, 1991). By the late 1870s, James was teaching classes devoted exclusively to the topic of psychology.

At about the same time, James began writing a comprehensive textbook of psychology, a task that would take him more than a decade. James’s Principles of Psychology was finally published in 1890. Despite its length of more than 1,400 pages, Principles of Psychology quickly became the leading psychology textbook. In it, James discussed such diverse topics as brain function, habit, memory, sensation, perception, and emotion. James’s views had an enormous impact on the development of psychology in the United States.

James’s ideas became the basis for a new school of psychology, called functionalism. Functionalism stressed the importance of how behavior functions to allow people and animals to adapt to their environments. Unlike structuralists, functionalists did not limit their methods to introspection. They expanded the scope of psychological research to include direct observation of living creatures in natural settings. They also examined how psychology could be applied to areas like education, child rearing, and the work environment.

functionalism

Early school of psychology that emphasized studying the purpose, or function, of behavior and mental experiences.

Both the structuralists and the functionalists thought that psychology should focus on the study of conscious experiences. But the functionalists had very different ideas about the nature of consciousness and how it should be studied. Rather than trying to identify the essential structures of consciousness at a given moment, James saw consciousness as an ongoing stream of mental activity that shifts and changes.

Like structuralism, functionalism no longer exists as a distinct school of thought in contemporary psychology. Nevertheless, functionalism’s twin themes of the importance of the adaptive role of behavior and the application of psychology to enhance human behavior continue to be evident in modern psychology.

WILLIAM JAMES AND HIS STUDENTS

G. Stanley Hall (1844–1924) G. Stanley Hall helped organize psychology in the United States. Among his many achievements was the establishment of the first psychology research laboratory in the United States. Hall also founded the American Psychological Association.
Corbis
Mary Whiton Calkins (1863–1930) Under the direction of William James, Mary Whiton Calkins completed all the requirements for a Ph.D. in psychology. Calkins had a distinguished professional career. She established a psychology laboratory at Wellesley College and became the first woman president of the American Psychological Association.

Like Wundt, James profoundly influenced psychology through his students, many of whom became prominent American psychologists. Two of James’s most notable students were G. Stanley Hall and Mary Whiton Calkins.

In 1878, G. Stanley Hall received the first Ph.D. in psychology awarded in the United States. Hall founded the first psychology research laboratory in the United States at Johns Hopkins University in 1883. He also began publishing the American Journal of Psychology, the first U.S. journal devoted to psychology. Most important, in 1892, Hall founded the American Psychological Association and was elected its first president (Anderson, 2012). Today, the American Psychological Association (APA) is the world’s largest professional organization of psychologists, with approximately 150,000 members.

In 1890, Mary Whiton Calkins was assigned the task of teaching experimental psychology at a new women’s college—Wellesley College. Calkins studied with James at nearby Harvard University. She completed all the requirements for a Ph.D. in psychology. However, Harvard refused to grant her the Ph.D. degree because she was a woman and at the time Harvard was not a coeducational institution (Pickren & Rutherford, 2010).

Although never awarded the degree she had earned, Calkins made several notable contributions to psychology. She conducted research in many areas, including dreams, memory, and personality. In 1891, she established a psychology laboratory at Wellesley College. At the turn of the twentieth century, she wrote a well-received textbook, titled Introduction to Psychology. In 1905, Calkins was elected president of the American Psychological Association—the first woman, but not the last, to hold that position.

Just for the record, the first American woman to earn an official Ph.D. in psychology was Margaret Floy Washburn. Washburn was Edward Titchener’s first doctoral student at Cornell University. She strongly advocated the scientific study of the mental processes of different animal species. In 1908, she published an influential text, titled The Animal Mind. Her book summarized research on sensation, perception, learning, and other “inner experiences” of different animal species. In 1921, Washburn became the second woman elected president of the American Psychological Association (Viney & Burlingame-Lee, 2003).

Finally, one of G. Stanley Hall’s notable students was Francis C. Sumner. Sumner was the first African American to receive a Ph.D. in psychology, awarded by Clark University in 1920. After teaching at several southern universities, Sumner moved to Howard University in Washington, D.C. At Howard he published papers on a wide variety of topics and chaired a psychology department that produced more African American psychologists than all other American colleges and universities combined (Guthrie, 2000, 2004). One of Sumner’s most famous students was Kenneth Bancroft Clark. Clark’s research on the negative effects of discrimination was instrumental in the U.S. Supreme Court’s 1954 decision to end segregation in schools (Jackson, 2006). In 1970, Clark became the first African American president of the American Psychological Association (Belgrave & Allison, 2010).

Francis C. Sumner (1895–1954) Francis Sumner studied under G. Stanley Hall at Clark University. In 1920, he became the first African American to earn a Ph.D. in psychology. Sumner later joined Howard University in Washington, D.C., and helped create a strong psychology program that led the country in training African American psychologists (Belgrave & Allison, 2010).
Margaret Floy Washburn (1871–1939) After becoming the first American woman to earn an official Ph.D. in psychology, Washburn went on to a distinguished career. Despite the discrimination against women that was widespread in higher education during the early twentieth century, Washburn made many contributions to psychology. She was the second woman to be elected president of the American Psychological Association.

Possible sample answer: Two early schools of thought in psychology—structuralism and functionalism—focused on introspection, examining mental processes by having people “look within.” Edward Titchener founded structuralim which focused on finding the "structure" or component parts of sensations and feelings. William James founded functionalism which focused on studying the purpose or function of behavior and mental processes. James, who was influenced by Darwin's theories,saw consciousness as an ongoing stream of mental activity that shifts and changes.

Sigmund Freud: PSYCHOANALYSIS

Sigmund Freud (1856–1939) In 1909, Freud (front left) and several other psychoanalysts were invited by G. Stanley Hall (front center) to participate in Clark University’s twentieth-anniversary celebration in Worcester, Massachusetts (Hogan, 2003). Freud delivered five lectures on psychoanalysis. Listening in the audience was William James, who later wrote to a friend that Freud struck him as “a man obsessed with fixed ideas” (Rosenzweig, 1997). Carl Jung (front right), who later developed his own theory of personality, also attended this historic conference.

MYTH !lhtriangle! SCIENCE

Is it true that Sigmund Freud was the first psychologist?

Wundt, James, and other early psychologists emphasized the study of conscious experiences. But at the turn of the twentieth century, new approaches challenged the principles of both structuralism and functionalism.

In Vienna, Austria, a physician named Sigmund Freud was developing an intriguing theory of personality based on uncovering causes of behavior that were unconscious, or hidden from the person’s conscious awareness. Freud’s school of thought, called psychoanalysis, emphasized the role of unconscious conflicts in determining behavior and personality. Freud himself was a neurologist, not a psychologist. Nevertheless, psychoanalysis had a strong influence on psychological thinking in the early part of the century.

psychoanalysis

Personality theory and form of psychotherapy that emphasizes the role of unconscious factors in personality and behavior.

Freud’s psychoanalytic theory of personality and behavior was based largely on his work with his patients and on insights derived from self-analysis. Freud believed that human behavior was motivated by unconscious conflicts that were almost always sexual or aggressive in nature. Past experiences, especially childhood experiences, were thought to be critical in the formation of adult personality and behavior. According to Freud (1904), glimpses of these unconscious impulses are revealed in everyday life in dreams, memory blocks, slips of the tongue, and spontaneous humor. Freud believed that when unconscious conflicts became extreme, psychological disorders could result.

Freud’s psychoanalytic theory of personality also provided the basis for a distinct form of psychotherapy. Many of the fundamental ideas of psychoanalysis continue to influence psychologists and other professionals in the mental health field. We’ll explore Freud’s theory in more depth in Chapter 11 on personality and Chapter 15 on psychotherapy.

John B. Watson: BEHAVIORISM

The course of psychology changed dramatically in the early 1900s when another approach, called behaviorism, emerged as a dominating force. Behaviorism rejected the emphasis on consciousness promoted by structuralism and functionalism. It also flatly rejected Freudian notions about unconscious influences, claiming that such ideas were unscientific and impossible to test. Instead, behaviorism contended that psychology should focus its scientific investigations strictly on overt behavior—observable behaviors that could be objectively measured and verified.

behaviorism

School of psychology and theoretical viewpoint that emphasizes the study of observable behaviors, especially as they pertain to the process of learning.

Three Key Scientists in the Development of Behaviorism Building on the pioneering research of Russian physiologist Ivan Pavlov, American psychologist John B. Watson founded the school of behaviorism. Behaviorism advocated that psychology should study observable behaviors, not mental processes. Following Watson, B. F. Skinner continued to champion the ideas of behaviorism. Skinner became one of the most influential psychologists of the twentieth century. Like Watson, he strongly advocated the study of observable behaviors rather than mental processes.

Behaviorism is another example of the influence of physiology on psychology. Behaviorism grew out of the pioneering work of a Russian physiologist named Ivan Pavlov. Pavlov demonstrated that dogs could learn to associate a neutral stimulus, such as the sound of a bell, with an automatic behavior, such as reflexively salivating to food. Once an association between the sound of the bell and the food was formed, the sound of the bell alone would trigger the salivation reflex in the dog. Pavlov enthusiastically believed he had discovered the mechanism by which all behaviors were learned.

In the United States, a young, dynamic psychologist named John B. Watson shared Pavlov’s enthusiasm. Watson (1913) championed behaviorism as a new school of psychology. Structuralism was still an influential perspective, but Watson strongly objected to both its method of introspection and its focus on conscious mental processes. As Watson (1924) wrote in his classic book, Behaviorism:

Behaviorism, on the contrary, holds that the subject matter of human psychology is the behavior of the human being. Behaviorism claims that consciousness is neither a definite nor a usable concept. The behaviorist, who has been trained always as an experimentalist, holds, further, that belief in the existence of consciousness goes back to the ancient days of superstition and magic.

The influence of behaviorism on American psychology was enormous. The goal of the behaviorists was to discover the fundamental principles of learning—how behavior is acquired and modified in response to environmental influences. For the most part, the behaviorists studied animal behavior under carefully controlled laboratory conditions.

Although Watson left academic psychology in the early 1920s, behaviorism was later championed by an equally forceful proponent—the famous American psychologist B. F. Skinner. Like Watson, Skinner believed that psychology should restrict itself to studying outwardly observable behaviors that could be measured and verified. In compelling experimental demonstrations, Skinner systematically used reinforcement or punishment to shape the behaviorc of rats and pigeons.

Between Watson and Skinner, behaviorism dominated American psychology for almost half a century. During that time, the study of conscious experiences was largely ignored as a topic in psychology (Baars, 2005). In Chapter 5, on learning, we’ll look at the lives and contributions of Pavlov, Watson, and Skinner in greater detail.

Possible sample answer: Psychoanalysis is a personality theory and form of psychotherapy that emphasizes the role of unconscious factors in personality and behavior. Behaviorism emphasizes the study of observable behaviors, especially as they pertain to the process of learning. Behaviorists take an objective approach to psychology focusing on behaviors that can be measured and verified.

Carl Rogers: HUMANISTIC PSYCHOLOGY

Two Leaders in the Development of Humanistic Psychology Carl Rogers and Abraham Maslow were key figures in establishing humanistic psychology. Humanistic psychology emphasized the importance of self-determination, creativity, and human potential (Serlin, 2012). The ideas of Carl Rogers have been particularly influential in modern psychotherapy. Abraham Maslow’s theory of motivation emphasized the importance of psychological growth.

For several decades, behaviorism and psychoanalysis were the perspectives that most influenced the thinking of American psychologists. In the 1950s, a new school of thought emerged, called humanistic psychology. Because humanistic psychology was distinctly different from both psychoanalysis and behaviorism, it was sometimes referred to as the “third force” in American psychology (Waterman, 2013; Watson & others, 2011).

humanistic psychology

School of psychology and theoretical viewpoint that emphasizes each person’s unique potential for psychological growth and self-direction.

Humanistic psychology was largely founded by American psychologist Carl Rogers (Elliott & Farber, 2010). Like Freud, Rogers was influenced by his experiences with his psychotherapy clients. However, rather than emphasizing unconscious conflicts, Rogers emphasized the conscious experiences of his clients, including each person’s unique potential for psychological growth and self-direction. In contrast to the behaviorists, who saw human behavior as being shaped and maintained by external causes, Rogers emphasized self-determination, free will, and the importance of choice in human behavior (Elliott & Farber, 2010; Kirschenbaum & Jourdan, 2005).

Abraham Maslow was another advocate of humanistic psychology. Maslow developed a theory of motivation that emphasized psychological growth, which we’ll discuss in Chapter 8. Like psychoanalysis, humanistic psychology included not only influential theories of personality but also a form of psychotherapy, which we’ll discuss in later chapters.

By briefly stepping backward in time, you’ve seen how the debates among the key thinkers in psychology’s history shaped the development of psychology as a whole. Each of the schools that we’ve described had an impact on the topics and methods of psychological research. As you’ll see throughout this textbook, that impact has been a lasting one. In the next sections, we’ll touch on some of the more recent developments in psychology’s evolution. We’ll also explore the diversity that characterizes contemporary psychology.
