Module 1

Positive Psychology

Psychology's first hundred years focused on understanding and treating troubles, such as abuse and anxiety, depression and disease, prejudice and poverty. Much of today's psychology continues the exploration of such challenges. Without slighting the need to repair damage and cure disease, Martin Seligman and others (2002, 2005, 2011) have called for more research on human flourishing. These psychologists call their approach positive psychology. They believe that happiness is a by-product of a pleasant, engaged, and meaningful life. Thus, positive psychology uses scientific methods to explore the building of a "good life" that engages our skills, and a "meaningful life" that points beyond ourselves.

The Retrieval Practice questions

will challenge you to retrieve what you have learned, and thus better remember it. The end-of-section Review includes the collected Learning Objective Questions and key terms for self-testing. Complete Chapter Reviews can be found in Appendix C. Additional self-test questions in a variety of formats appear together, organized by section, at the end of each chapter, with answers appearing in Appendix D. Survey, question, read . . . Four additional study tips may further boost your learning: Distribute your study time. One of psychology's oldest findings is that spaced practice promotes better retention than massed practice. You'll remember material better if you space your time over several study periods—perhaps one hour a day, six days a week—rather than cram it into one long study blitz. For example, rather than trying to read an entire chapter in a single sitting, read just one main section and then turn to something else. Interleaving your study of psychology with your study of other subjects boosts long-term retention and protects against overconfidence (Kornell & Bjork, 2008; Taylor & Rohrer, 2010). Spacing your study sessions requires a disciplined approach to managing your time. (Richard O. Straub explains time management in a helpful preface at the beginning of this text.) Learn to think critically. Whether you are reading or in class, note people's assumptions and values. What perspective or bias underlies an argument? Evaluate evidence. Is it anecdotal? Or is it based on informative experiments? Assess conclusions. Are there alternative explanations? Process class information actively. Listen for the main ideas and sub-ideas of a lecture. Write them down. Ask questions during and after class. In class, as in your private study, process the information actively and you will understand and retain it better. As psychologist William James urged a century ago, "No reception without reaction, no impression without . . . expression." Make the information your own. Take notes in your own words. (Handwritten notes typically engage more active processing into your own words, and thus better memory, than does verbatim note-taking on laptops [Mueller & Oppenheimer, 2014]). Relate what you read to what you already know. Tell someone else about it. (As any teacher will confirm, to teach is to remember.) Overlearn. Psychology tells us that overlearning improves retention. We are prone to overestimating how much we know. You may understand a chapter as you read it, but that feeling of familiarity can be deceptively comforting. Using the Retrieval Practice questions as well as LaunchPad's varied opportunities, devote extra study time to testing your knowledge and exploring psychology. Memory experts Elizabeth Bjork and Robert Bjork (2011) offer the bottom line for how to improve your retention and your grades: Spend less time on the input side and more time on the output side, such as summarizing what you have read from memory or getting together with friends and asking each other questions. Any activities that involve testing yourself—that is, activities that require you to retrieve or generate information, rather than just representing information to yourself— will make your learning both more durable and flexible. (p. 63)

FUNCTIONALISM

Hoping to assemble the mind's structure from simple elements was rather like trying to understand a car by examining its disconnected parts. Philosopher - psychologist William James thought it would be more fruitful to consider the evolved functions of our thoughts and feelings. Smelling is what the nose does; thinking is what the brain does. But why do the nose and brain do these things? Under the influence of evolutionary theorist Charles Darwin, James assumed that thinking, like smelling, developed because it was adaptive—it contributed to our ancestors' survival. Consciousness serves a function. It enables us to consider our past, adjust to our present, and plan our future. James encouraged explorations of the functions of emotions, memories, willpower, habits, and moment - to - moment streams of consciousness. James' writings moved the publisher Henry Holt to offer James a contract for a textbook of the new science of psychology. James agreed and began work in 1878, with an apology for requesting two years to finish his writing. The text proved an unexpected chore and actually took him 12 years. (Why am I not surprised?) More than a century later, people still read the resulting Principles of Psychology (1890) and marvel at the brilliance and elegance with which James introduced psychology to the educated public.

Psychological Science Develops P-2

How did psychology continue to develop from the 1920s through today? Behaviorism In the field's early days, many psychologists shared with the English essayist C. S. Lewis the view that "there is one thing, and only one in the whole universe which we know more about than we could learn from external observation." That one thing, Lewis said, is ourselves. "We have, so to speak, inside information" (1960, pp. 18-19). Wundt and Titchener focused on inner sensations, images, and feelings. James also engaged in introspective examination of the stream of consciousness and of emotion. For these and other early pioneers, psychology was defined as "the science of mental life." That definition continued until the 1920s, when the first of two provocative American psychologists appeared on the scene. John B. Watson, and later B. F. Skinner, dismissed introspection and redefined psychology as "the scientific study of observable behavior." After all, they said, science is rooted in observation: What you cannot observe and measure, you cannot scientifically study. You cannot observe a sensation, a feeling, or a thought, but you can observe and record people's behavior as they respond to and learn in different situations. Many agreed, and the behaviorists became one of two major forces in psychology well into the 1960s.

Contemporary Psychology P-3

How has our understanding of biology and experience, culture and gender, and human flourishing shaped contemporary psychology? The young sscience of psychology developed from the more established fields of philosophy and biology. Wundt was both a philosopher and a physiologist. James was an American philosopher. Freud was an Austrian physician. Ivan Pavlov, who pioneered the study of learning, was a Russian physiologist. Jean Piaget, the last century's most influential observer of children, was a Swiss biologist. These "Magellans of the mind," as Morton Hunt (1993) has called them, illustrate psychology's origins in many disciplines and many countries. Like those pioneers, today's psychologists are citizens of many lands. The International Union of Psychological Science has 182 member nations, from Albania to Zimbabwe. In China, the first university psychology department began in 1978; by 2008 there were nearly 200 (Han, 2008; Tversky, 2008). Moreover, thanks to international publications, joint meetings, and the Internet, collaboration and communication now cross borders. Psychology is growing and it is globalizing. The story of psychology—the subject of this book—continues to develop in many places, at many levels, with interests ranging from the study of nerve cell activity to the study of international conflicts

Cognitive Revolution

In the 1960s, the cognitive revolution led the field back to its early interest in mental processes, such as the importance of how our mind processes and retains information. Cognitive psychology scientifically explores the ways we perceive, process, and remember information. The cognitive approach has given us new ways to understand ourselves and to treat disorders such as depression. Cognitive neuroscience was birthed by the marriage of cognitive psychology (the science of mind) and neuroscience (the science of brain). This interdisciplinary field studies the brain activity underlying mental activity.

Freudian Psychology

The other major force was Freudian psychology, which emphasized the ways our unconscious thought processes and our emotional responses to childhood experiences affect our behavior. (In chapters to come, we'll look more closely at Sigmund Freud's teachings, including his theory of personality, and his views on unconscious sexual conflicts and the mind's defenses against its own wishes and impulses.)

Evolutionary Psychology and Behavior Genetics

Are our human traits present at birth, or do they develop through experience? This has been psychology's biggest and most persistent issue. But the debate over the nature- nurture issue is ancient. The Greek philosopher Plato (428-348 b.c.e.) assumed that we inherit character and intelligence and that certain ideas are inborn. Aristotle (384-322 b.c.e.) countered that there is nothing in the mind that does not first come in from the external world through the senses. In the 1600s, European philosophers rekindled the debate. John Locke argued that the mind is a blank slate on which experience writes. René Descartes disagreed, believing that some ideas are innate. Descartes' views gained support from a curious naturalist two centuries later. In 1831, an indifferent student but ardent collector of beetles, mollusks, and shells set sail on a historic round-the-world journey. The 22-year-old voyager, Charles Darwin, pondered the incredible species variation he encountered, including tortoises on one island that differed from those on nearby islands. Darwin's 1859 On the Origin of Species explained this diversity by proposing the evolutionary process of natural selection: From among chance variations, nature selects traits that best enable an organism to survive and reproduce in a particular environment. Darwin's principle of natural selection—what philosopher Daniel Dennett (1996) has called "the single best idea anyone has ever had"—is still with us 150+ years later as biology's organizing principle. Evolution also has become an important principle for twenty-firstcentury psychology. This would surely have pleased Darwin, who believed his theory explained not only animal structures (such as a polar bear's white coat) but also animal behaviors (such as the emotional expressions associated with human lust and rage). The nature -nurture issue recurs throughout this text as today's psychologists explore the relative contributions of biology and experience. They ask, for example, how are we humans alike because of our common biology and evolutionary history? Charles That's the focus of evolutionary psychology. And how are we diverse because of our differing genes and environments? That's the focus of behavior genetics. Are gender differences biologically predisposed or socially constructed? Is children's grammar mostly innate or formed by experience? How are intelligence and personality differences influenced by heredity and by environment? Are sexual behaviors more "pushed" by inner biology or "pulled" by external incentives? Should we treat psychological disorders—depression, for example—as disorders of the brain, disorders of thought, or both? Such debates continue. Yet over and over again we will see that in contemporary science the nature - nurture tension dissolves: Nurture works on what nature endows. Our species is biologically endowed with an enormous capacity to learn and adapt. Moreover, every psychological event (every thought, every emotion) is simultaneously a biological event. Thus, depression can be both a brain disorder and a thought disorder

STRUCTURALISM

As physicists and chemists discerned the structure of matter, so Edward Bradford Titchener aimed to discover the mind's structure. He engaged people in self - reflective introspection (looking inward), training them to report elements of their experience as they looked at a rose, listened to a metronome, smelled a scent, or tasted a substance. What were their immediate sensations, their images, their feelings? And how did these relate to one another? Alas, introspection proved somewhat unreliable. It required smart, verbal people, and its results varied from person to person and experience to experience. As introspection waned, so did structuralism.

Humanistic Psychology

As the behaviorists had rejected the early 1900's definition of psychology, two other groups rejected the behaviorist definition in the 1960s. The first, the humanistic psychologists, led by Carl Rogers and Abraham Maslow, found both Freudian psychology and behaviorism too limiting. Rather than focusing on the meaning of early childhood memories or the learning of conditioned responses, the humanistic psychologists drew attention to ways that current environmental influences can nurture or limit our growth potential, and to the importance of having our needs for love and acceptance satisfied.

Improve Your Retention—and Your Grades P-6 How can psychological principles help you learn and remember?

Do you, like most students, assume that the way to cement your new learning is to reread? What helps even more—and what this book therefore encourages—is repeated self-testing and rehearsal of previously studied material. Memory researchers Henry Roediger and Jeffrey Karpicke (2006) call this phenomenon the testing effect. (It is also sometimes called the retrieval practice effect or test-enhanced learning.) They note that "testing is a powerful means of improving learning, not just assessing it." In one of their studies, students recalled the meaning of 40 previously learned Swahili words much better if tested repeatedly than if they spent the same time restudying the words (Karpicke & Roediger, 2008). As you will see in Chapter 8, to master information you must actively process it. Your mind is not like your stomach, something to be filled passively; it is more like a muscle that grows stronger with exercise. Countless experiments reveal that people learn and remember best when they put material in their own words, rehearse it, and then retrieve and review it again.

Psychology's Three Main Levels of Analysis P-4 What are psychology's levels of analysis and related perspectives?

Each of us is a complex system that is part of a larger social system. But each of us is also composed of smaller systems, such as our nervous system and body organs, which are composed of still smaller systems—cells, molecules, and atoms. These tiered systems suggest different levels of analysis, which offer complementary outlooks. It's like explaining horrific school shootings. Is it because the shooters have brain disorders or genetic tendencies that cause them to be violent? Because they have been rewarded for violent behavior? Because we live in a gun-promoting society that accepts violence? Such perspectives are complementary because "everything is related to everything else" (Brewer, 1996). Together, different levels of analysis form an integrated bio psychosocial approach, which considers the influences of biological, psychological, and social-cultural factors (FIGURE 1). Each level provides a valuable playing card in psychology's explanatory deck. It's a vantage point for looking at a behavior or mental process, yet each by itself is incomplete. Like different academic disciplines, psychology's varied perspectives ask different questions and have their own limits. One perspective may stress the biological, psychological, or social-cultural level more than another, but the different perspectives described in TABLE1 on the next page complement one another. Consider, for example, how they shed light on anger: •Someone working from a neuroscience perspective might study brain circuits that cause us to be red in the face and "hot under the collar." •Someone working from the evolutionary perspective might analyze how anger facilitated the survival of our ancestors' genes. • Someone working from the behavior genetics perspective might study how heredity and experience influence our individual differences in temperament. Someone working from the psychodynamic perspective might view an outburst as an outlet for unconscious hostility. •Someone working from the behavioral perspective might attempt to determine which external stimuli trigger angry responses or aggressive acts. • Someone working from the cognitive perspective might study how our interpretation of a situation affects our anger and how our anger affects our thinking. • Someone working from the social - cultural perspective might explore how expressions of anger vary across cultural contexts. The point to remember: Like two-dimensional views of a three-dimensional object, each of psychology's perspectives is helpful. But each by itself fails to reveal the whole picture.

First Women in Psychology

James' legacy stems partly from his Harvard mentoring and his writing. In 1890, over the objections of Harvard's president, he admitted Mary Whiton Calkins into his graduate seminar (Scarborough & Furumoto, 1987). (In those years women lacked even the right to vote.) When Calkins joined, the other students (all men) dropped out. So James tutored her alone. Later, she finished all of Harvard's Ph.D. requirements, outscoring all the male students on the qualifying exams. Alas, Harvard denied her the degree she had earned, offering her instead a degree from Radcliffe College, its undergraduate "sister" school for women. Calkins resisted the unequal treatment and refused the degree. She nevertheless went on to become a distinguished memory researcher and the American Psychological Association's (APA's) first female president in 1905. The honor of being the first female psychology Ph.D. later fell to Margaret Floy Washburn, who also wrote an influential book, The Animal Mind, and became the second female APA president in 1921. But Washburn's gender barred doors for her, too. Although her thesis was the first foreign study Wundt published in his psychology journal, she could not join the all-male organization of experimental psychologists founded by Titchener, her own graduate adviser (Johnson, 1997). (What a different world from the recent past—1996 to 2014—when women were 10 of the 19 elected presidents of the science - oriented Association for Psychological Science. In the United States, Canada, and Europe, most psychology doctorates are now earned by women.)

Psychology's Subfields P-5 What are psychology's main subfields?

Picturing a chemist at work, you may envision a white - coated scientist surrounded by test tubes and high - tech equipment. Picture a psychologist at work and you would be right to envision • a white - coated scientist probing a rat's brain. • an intelligence researcher measuring how quickly an infant shows boredom by looking away from a familiar picture. •an executive evaluating a new "healthy life styles" training program for employees. •someone at a computer analyzing data on whether adopted teens' temperaments more closely resemble those of their adoptive parents or their biological parents. a therapist listening carefully to a depressed client's thoughts. •a traveler visiting another culture and collecting data on variations in human values and behaviors. •a teacher or writer sharing the joy of psychology with others. The cluster of subfields we call psychology is a meeting ground for different disciplines. "Psychology is a hub scientific discipline," said Association for Psychological Science president John Cacioppo (2007). Thus, it's a perfect home for those with wide ranging interests. In its diverse activities, from biological experimentation to cultural comparisons, the tribe of psychology is united by a common quest: describing and explaining behavior and the mind underlying it. Some psychologists conduct basic research that builds psychology's knowledge base. We will meet a wide variety of such researchers, including biological psychologists exploring the links between brain and mind; developmental psychologists studying our changing abilities from womb to tomb; cognitive psychologists experimenting with how we perceive, think, and solve problems; personality psychologists investigating our persistent traits; and social psychologists exploring how we view and affect one another.

Improve Your Retention—and Your Grades P-6 How can psychological principles help you learn and remember? II

The SQ3R study method incorporates these principles (McDaniel et al., 2009; Robinson, 1970). SQ3R is an acronym for its five steps: Survey, Question, Read, Retrieve,2 Review. To study a chapter, first survey, taking a bird's-eye view. Scan the headings, and notice how the chapter is organized. Before you read each main section, try to answer its numbered Learning Objective Question (for this section: "How can psychological principles help you learn and remember?"). Roediger and Bridgid Finn (2009) have found that "trying and failing to retrieve the answer is actually helpful to learning." Those who test their understanding before reading, and discover what they don't yet know, will learn and remember better. Then read, actively searching for the answer to the question. At each sitting, read only as much of the chapter (usually a single main section) as you can absorb without tiring. Read actively and critically. Ask questions. Take notes. Make the ideas your own: How does what you've read relate to your own life? Does it support or challenge your assumptions? How convincing is the evidence? Having read a section, retrieve its main ideas. "Active retrieval promotes meaningful learning," says Karpicke (2012). So test yourself. This will not only help you figure out what you know, the testing itself will help you learn and retain the information more effectively. Even better, test yourself repeatedly. To facilitate this, we offer periodic Retrieval Practice opportunities throughout each chapter (see, for example, the questions in this chapter). After answering these questions for yourself, you can check the answers provided, and reread as needed. Finally, review: Read over any notes you have taken, again with an eye on the chapter's organization, and quickly review the whole chapter. Write or say what a concept is before rereading to check your understanding. Survey, question, read, retrieve, review. I have organized this book's chapters to facilitate your use of the SQ3R study system. Each chapter begins with an outline that aids your survey. Headings and Learning Objective Questions suggest issues and concepts you should consider as you read. The material is organized into sections of " readable length.

Psychology's Subfields P-5 What are psychology's main subfields? II

These and other psychologists also may conduct applied research, tackling practical problems. Industrial-organizational psychologists, for example, use psychology's concepts and methods in the workplace to help organizations and companies select and train employees, boost morale and productivity, design products, and implement systems. Although most psychology textbooks focus on psychological science, psychology is also a helping profession devoted to such practical issues as how to have a happy marriage, how to overcome anxiety or depression, and how to raise thriving children. As a science, psychology at its best bases such interventions on evidence of effectiveness. Counseling psychologists help people to cope with challenges and crises (including academic, vocational, and marital issues) and to improve their personal and social functioning. Clinical psychologists assess and treat people with mental, emotional, and behavior disorders. Both counseling and clinical psychologists administer and interpret tests, provide counseling and therapy, and sometimes conduct basic and applied research. By contrast, psychiatrists, who also may provide psychotherapy, are medical doctors licensed to prescribe drugs and otherwise treat physical causes of psychological disorders. Rather than seeking to change people to fit their environment, community psychologists work to create social and physical environments that are healthy for all (Bradshaw et al., 2009; Trickett, 2009). For example, if school bullying is a problem, some psychologists will seek to change the bullies. Knowing that many students struggle with the transition from elementary to middle school, they might train individual kids how to cope. Community psychologists instead seek ways to adapt the school experience to early adolescent needs. To prevent bullying, they might study how the school and neighborhood foster bullying and how to increase bystander intervention (Polanin et al., 2012). With perspectives ranging from the biological to the social, and with settings from the laboratory to the clinic, psychology relates to many fields. Psychologists teach in medical schools, law schools, and theological seminaries, and they work in hospitals, factories, and corporate offices. They engage in interdisciplinary studies, such as psychohistory (the psychological analysis of historical characters), psycholinguistics (the study of language and thinking), and psychoceramics (the study of crackpots).1 Psychology also influences modern culture. Knowledge transforms us. Learning about the solar system and the germ theory of disease alters the way people think and act. Learning about psychology's findings also changes people: They less often judge psychological disorders as moral failings, treatable by punishment and ostracism

Psychology's Subfields P-5 What are psychology's main subfields? III

They less often regard and treat women as men's mental inferiors. They less often view and raise children as ignorant, willful beasts in need of taming. "In each case," noted Morton Hunt (1990, p. 206), "knowledge has modified attitudes, and, through them, behavior." Once aware of psychology's well - researched ideas—about how body and mind connect, how a child's mind grows, how we construct our perceptions, how we remember (and misremember) our experiences, how people across the world differ (and are alike)—your mind may never again be quite the same. But bear in mind psychology's limits. Don't expect it to answer the ultimate questions, such as those posed by Russian novelist Leo Tolstoy (1904): "Why should I live? Why should I do anything? Is there in life any purpose which the inevitable death that awaits me does not undo and destroy?" Although many of life's significant questions are beyond psychology, some very important ones are illuminated by even a first psychology course. Through painstaking research, psychologists have gained insights into brain and mind, dreams and memories, depression and joy. Even the unanswered questions can renew our sense of mystery about things we do not yet understand. Moreover, your study of psychology can help teach you how to ask and answer important questions—how to think critically as you evaluate competing ideas and claims. Psychology deepens our appreciation for how we humans perceive, think, feel, and act. By so doing it can indeed enrich our lives and enlarge our vision. Through this book we hope to help guide you toward that end. As educator Charles Eliot said a century ago:

Modern Definition of Psychology

To encompass psychology's concern with observable behavior and with inner thoughts and feelings, today we define psychology as the science of behavior and mental processes. Let's unpack this definition. Behavior is anything an organism does—any action we can observe and record. Yelling, smiling, blinking, sweating, talking, and questionnaire marking are all observable behaviors. Mental processes are the internal, subjective experiences we infer from behavior—sensations, perceptions, dreams, thoughts, beliefs, and feelings. The key word in psychology's definition is science. Psychology is less a set of findings than a way of asking and answering questions. Our aim, then, is not merely to report results but also to show you how psychologists play their game. You will see how researchers evaluate conflicting opinions and ideas. And you will learn how all of us, whether scientists or simply curious people, can think smarter when experiencing and explaining the events of our lives

Cross-Cultural and Gender Psychology

What can we learn about people in general from psychological studies done in one time and place—often with people from what Joseph Henrich, Steven Heine, and Ara Norenzayan (2010) call the WEIRD cultures (Western, Educated, Industrialized, Rich, and Democratic)? As we will see time and again, culture—shared ideas and behaviors that one generation passes on to the next—matters. Our culture shapes our behavior. It influences our standards of promptness and frankness, our attitudes toward premarital sex and varying body shapes, our tendency to be casual or formal, our willingness to make eye contact, our conversational distance, and much, much more. Being aware of such differences, we can restrain our assumptions that others will think and act as we do. It is also true, however, that our shared biological heritage unites us as a universal human family. The same underlying processes guide people everywhere: • People diagnosed with specific learning disorder (formerly called dyslexia) exhibit the same brain malfunction whether they are Italian, French, or British (Paulesu et al., 2001). • Variation in languages may impede communication across cultures. Yet all languages share deep principles of grammar, and people from opposite hemispheres can communicate with a smile or a frown. • People in different cultures vary in feelings of loneliness. But across cultures, loneliness is magnified by shyness, low self-esteem, and being unmarried (Jones et al., 1985; Rokach et al., 2002). We are each in certain respects like all others, like some others, and like no other. Studying people of all races and cultures helps us discern our similarities and our differences, our human kinship and our diversity. You will see throughout this book that gender matters, too. Researchers report gender differences in what we dream, in how we express and detect emotions, and in our risk for alcohol use disorder, depression, and eating disorders. Gender differences fascinate us, and studying them is potentially beneficial. For example, many researchers have observed that women carry on conversations more readily to build relationships, while men talk more to give information and advice (Tannen, 2001). Knowing this difference can help us prevent conflicts and misunderstandings in everyday relationships. But again, psychologically as well as biologically, women and men are overwhelmingly similar. Whether female or male, we learn to walk at about the same age. We experience the same sensations of light and sound. We feel the same pangs of hunger, desire, and fear. We exhibit similar overall intelligence and well - being. The point to remember: Even when specific attitudes and behaviors vary by gender or across cultures, as they often do, the underlying causes are much the same.

Psychological Science Is Born P-1

What were some important milestones in psychology's early development? To be human is to be curious about ourselves and the world around us. Before 300 b.c.e., the Greek naturalist and philosopher Aristotle theorized about learning and memory, motivation and emotion, perception and personality. Today we chuckle at some of his guesses, like his suggestion that a meal makes us sleepy by causing gas and heat to collect around the source of our personality, the heart. But credit Aristotle with asking the right questions. Psychology's First Laboratory Philosophers' thinking about thinking continued until the birth of psychology as we know it, on a December day in 1879, in a small, third-floor room at Germany's University of Leipzig. There, two young men were helping an austere, middle - aged professor, Wilhelm Wundt, create an experimental apparatus. Their machine measured the time lag between people's hearing a ball hit a platform and their pressing a telegraph key (Hunt, 1993). Curiously, people responded in about one - tenth of a second when asked to press the key as soon as the sound occurred—and in about two - tenths of a second when asked to press the key as soon as they were consciously aware of perceiving the sound. (To be aware of one's awareness takes a little longer.) Wundt was seeking to measure "atoms of the mind"—the fastest and simplest mental processes. So began the first psychological laboratory, staffed by Wundt and by psychology's first graduate students. Structuralism and Functionalism Before long, this new science of psychology became organized into different branches, or schools of thought, each promoted by pioneering thinkers. Two early schools were structuralism and functionalism.

applied research

scientific study that aims to solve practical problems. counseling psychology a branch of psychology that assists people with problems in living (often related to school, work, or marriage) and in achieving greater well-being. clinical psychology a branch of psychology that studies, assesses, and treats people with psychological disorders. psychiatry a branch of medicine dealing with psychological disorders; practiced by physicians who sometimes provide medical (for example, drug) treatments as well as psychological therapy. community psychology a branch of psychology that studies how people interact with their social environments and how social institutions affect individuals and groups.
