  1. PSYCHOLOGY • What is Psychology? • Psychology is a word deriving from Greek roots: • Psyche – “soul” or “mind,” Logos – “word” • Psychology is the systematic study of behavior and experience

  2. The Goals of Psychologists • Psychologists engage in the study of psychology in order to understand, explain, predict and control behavior • What are the major philosophical issues that are relevant to this study? • Why we do what we do (causes of behavior). • Relationship of brain activity and the “mind” (Mind-Brain Problem). • Role of heredity and environment.

  3. The Major Philosophical Issues • Free will versus determinism – are the causes of behavior knowable, and is behavior predictable? • Free will is the belief that behavior is caused by an individual’s independent decision-making • What does independent mean? • Determinism is the assumption that everything that happens has a cause or determinant in the observable world. • We can isolate specific determinants of behavior.

  4. Major Philosophical Issues • Which perspective holds that behavior is fully predictable? • A determinist assumes everything that happens has a cause that can be known • A believer in free will assumes that even with complete information regarding causes and conditions, predictions regarding human behavior can never be fully accurate • How many of you believe you have free will?

  5. Major Philosophical Issues • The mind-brain problem: - How is experience related to the organ system called the brain? • Thoughts versus Brain activity • Dualism is the belief that the mind is separate from the brain but somehow controls the brain and through it also the rest of the body • Monism is the view that conscious experience is generated by and therefore is inseparable from the brain

  6. Major Philosophical Issues • The mind-brain problem • Data from brain imaging research such as PET (positron emission tomography) suggests that brain activity and mental activity are two aspects of the same thing • Yet the question is far from resolved

  7. Major Philosophical Issues • The nature-nurture issue • How do differences in behavior relate to differences in heredity and environment? • Some scientists assume the larger proportion of differences in potential and behavior are due to the influence of genes • Others assume that most differences are a result of aspects of the environment such as culture, expectations, and resources • This issue arises in virtually every field of psychology, and knowledge gained through research seldom provides a simple answer

  8. What Psychologists Do • Psychology is an academic, non-medical discipline that includes many branches and specialties • The educational requirements can vary, but generally involve study beyond the bachelor’s degree • A master’s degree, or a Ph.D./Psy.D. (doctor of psychology) are common terminal degrees in the discipline

  9. Figure 1.2 More than one-third of psychologists work in academic settings. The remainder find positions in a variety of settings (based on the data of Chamberlain, 2000).

  10. What Psychologists Do • There are many specialties in the broad science of psychology. Psychologists practice within their chosen specialty in 3 main areas: • Teaching and research • Service providers to individuals • Service providers to organizations

  11. What Psychologists Do • Teaching and research • Most teaching psychologists work in colleges and universities • Most psychologists who teach also engage in research and writing • Some psychologists are employed in full-time research positions

  12. What Psychologists Do • Major categories of psychological research: Biological psychology or neuroscience • A bio-psychologist tries to explain behavior in terms of biological factors, such as anatomy, electrical and chemical activities in the nervous system, and the effects of drugs, hormones, genetics and evolutionary pressures • Sample question: How do drug abuse, brain damage, and exposures to environmental toxins change nervous system functioning (and by extension, behavior)?

  13. What Psychologists Do • Major categories of psychological research: Evolutionary psychology • An evolutionary psychologist tries to explain behavior in terms of natural selection pressures promoting behaviors that lead to success in reproduction and survival. • Sample questions: What forces led to selection for human language abilities? What specific advantages in survival over other animals did language give early humans in the ancestral environment?

  14. What Psychologists Do • Major categories of psychological research: Learning and motivation • A psychologist who studies and does research in this area is interested in how behavior depends on outcomes of past behaviors and on current motivations • Sample question: Do frequent or consistent rewards for desired behaviors produce better learning than less frequent or less predictable rewards?

  15. What Psychologists Do • Major categories of psychological research: Cognitive psychology • A cognitive psychologist studies the processes of thinking and acquiring knowledge. • Sample question: What do “experts” in a field know or do that sets them apart from other people?

  16. What Psychologists Do • Major categories of psychological research: Developmental psychology • A developmental psychologist studies the behavioral capacities typical of different ages and how behavior changes with age. • Sample questions: What do people do or know as adults that they do not know as children? Why did this change occur? Was the change due to biological changes, increased experience, or a combination of these?

  17. What Psychologists Do • Major categories of psychological research: Social psychology • A social psychologist studies how an individual influences and is influenced by other people • Sample question: To what degree do the demands and expectations of authority figures influence our behavior? How strong is the human tendency to conform? 

  18. Concept Check • Which area of psychology research is concerned with whether or not punishment is an effective means of eliminating undesirable behaviors? • Learning and motivation • Which would ask if people will obey an authority figure even when that leader is demanding behavior that might be classified as immoral or wrong? • Social

  19. Concept Check • Which psychologist wants to know when language learning occurs most rapidly in children? • Developmental psychologist • Which psychologist would do research to determine how memories are stored in the brain? • Biological psychologist (Cognitive Neuroscientist) • Which psychologist would do research to determine how retention and recall of information in a college-level psychology course can be enhanced? • Cognitive psychologist

  20. What Psychologists Do • Service providers to individuals • There are many types of psychotherapists, professionals with training in psychology who specialize in helping people with psychological problem. Psychotherapists are trained in a variety of disciplines.

  46. Psychology Then and Now • The early era and the roots of psychology • The first psychological laboratory was established by William Wundt, Leipzig, Germany in 1879 • William Wundt was trained as a physician and did research on the workings of the senses. • Although other psychology experiments had been done, this was the first laboratory devoted exclusively to the activities of psychological research.

  47. Psychology Then and Now • The early era and the roots of psychology • Wundt’s fundamental question was: What are the components of experience, or mind? • He presented his subjects with a wide variety of stimuli, and asked them to look within themselves, to introspect. He tried to measure the changes in their experiences as the stimuli changes.

  48. Psychology Then and Now • The early era and the roots of psychology • Wundt and his students did experiments in a wide range of areas related to psychology, and they wrote prolifically about their findings. • Most importantly, Wundt demonstrated that it was possible to perform meaningful experiments in the science of psychology.

  49. Psychology Then and Now • The early era and the roots of psychology • Edward Titchener was a student of Wundt who immigrated to the United States in 1892. • He developed the approach he called structuralism. • In structuralism, the researcher attempts to describe the structures that compose the mind, its sensations, feelings and images.

  50. Psychology Then and Now • The early era and the roots of psychology • Titchener presented a stimulus to his subjects and asked them to analyze its separate features • After Titchener’s death in 1927, his research methods were abandoned • There was no feasible way to check the accuracy of his subjects’ observations • As psychology evolved through the 20th century, psychological researchers became more interested in describing and analyzing readily observable behaviors
