1 History and Approaches of Psychology

2 Psychology: The scientific study of behavior and mental processes
Roots of Psychology Psychology: The scientific study of behavior and mental processes Let’s break down the definition: Behavior: Anything that you do that can be observed Mental Processes: Internal experiences such as thoughts, feelings, sensations, and perceptions

3 Scientific psychology has four basic goals:
to describe, explain, predict, and change behavior and mental processes

4 Psychology as a Science
Psychology was not considered an area of scientific study until the 1870’s when the ideas philosophy and physiology were combined

5 Wilhelm Wundt Founder of scientific psychology
1879: set up first formal research laboratory in Germany 1881: established first psychological journal Focused studies on consciousness awareness of immediate experience Wundt is known as a voluntarist because he was interested in volitional behavior.

6 G. Stanley Hall Wundt’s student
Founded American Psychological Association (APA) Started America’s first research laboratory at John’s Hopkins University Began the first journal of psychology in America APA Website

7 EARLY APPROACHES: Structuralism
Established by Edward Titchener (student of Wundt) Task of psychology = analyze consciousness into its basic elements; study how elements are related Focus on sensations (vision, hearing, touch), feelings, images, and perception Investigations based on introspection by trained subjects Introspection = systematic self-observation of one’s own conscious experience

8 Early approaches: Functionalism
Created by William James Psychology should investigate the purpose of consciousness – how and why the mind functions Looked at overt behavior Applied Darwin’s theory of natural selection to humans inheritable characteristics that give humans with a competitive advantage are more likely to be passed on Developed into behaviorism and applied psychology

9 William James Main goal = explain human behavior
1890: Wrote first psychology textbook Principles of Psychology Argued consciousness is a flow of thoughts (stream of conscious)

10 MODERN APPROACHES

11 MODERN APPROACHES Psychoanalytic Behavioral Humanistic Cognitive
Biological Socio-Cultural Evolutionary Posters: Name of perspective Key people Buzz words /key concepts Illustration representing perspective Quote Advantages & disadvantages

12 PSYCHOANALYTIC THEORY
Sigmund Freud: viewed person as being pushed and pulled by unconscious wants & desires (sexual & aggressive in nature) Repression of wants & desires led to mental disorders later in life Developed psychoanalytic theory

13 People aren’t the masters of their own minds
PSYCHOANALTIC THEORY: Explains personality, motivation, and mental disorders by focusing on unconscious determinants of behavior People aren’t the masters of their own minds Emphasizes role of conflict in our lives and early childhood experiences Because we can’t accept certain thoughts in our conscious, they find their expression in dreams, slips of the tongue that appear as accidents and even jokes “Freudian Slips” Cause of disorders: Unconscious, unresolved repressed issues from past Treatment technique Psychoanalysis: Free association, dream analysis, TAT test View on personality: Id, ego, superego, psychosexual stages View on motivation: We strive to satisfy our id impulses but we must meet demands of society (super ego)

14 PSYCHOANALTIC THEORY Cause of disorders: Unconscious, unresolved repressed issues from past Treatment technique Psychoanalysis, dream analysis View on personality: Id, ego, superego, psychosexual stages View on motivation: We strive to satisfy our id impulses but we must meet demands of society (super ego)

16 Ego Superego Id

17 Psychoanalysis: Pros and Cons
Impact of childhood on development Many ideas still used in mainstream psychology Cons: No focus on observable behavior Can’t be scientifically proven Ignores other explanations Doesn’t look at changing behavior, just underlying causes

18 Believe behavior is governed by the environment
BEHAVIORAL: emphasizes observable behavior rather than the role of the consciousness. Believe behavior is governed by the environment John B. Watson (1913): Father of Behaviorism - observe & measure behavior. Known for “Little Albert” study Ivan Pavlov: Classical Conditioning - Involuntary behavior = Associative Learning in dogs through saliva responses after hearing a bell. View of cause of disorders: We are reinforced for maladaptive behaviors. Treatment technique : Change maladaptive behaviors through reinforcements. Systematic desensitization, token economy, aversion therapy View on personality : Our personality traits arise from reinforcement/ punishment View on motivation : We’re driven by extrinsic and intrinsic motivators. B. F. Skinner: Operant Conditioning. Voluntary behavior and learning due to consequences (reinforcement & punishment). Controlled by rewards = NO FREE WILL

19 BEHAVIORAL THERAPY View of cause of disorders: We are reinforced for maladaptive behaviors Treatment technique: Change maladaptive behaviors through reinforcements. Systematic desensitization, token economy, aversion therapy View on personality: Our personality traits arise from reinforcement/ punishment View on motivation: We’re driven by extrinsic and intrinsic motivators

20 Behaviorist Theory: Criticisms
Excludes behaviors that can’t be seen Not all behaviors can be explained through rewards and punishments Doesn’t acknowledge free will

21 Nature vs. Nurture Controversy
Nature: Certain elementary ideas are innate to the human mind; not gained through experience Men are born, not made Nurture: Anything we know we have learned through experience Men are made, not born

22 HUMANISM: emphasizes the unique qualities of humans, especially their their potential for personal growth Thought other approaches were “dehumanizing” and suggested people weren’t masters of their own destinies People have a basic need to continue to evolve and fulfill their potential; many psychological disturbances are due to thwarting these needs Abraham Maslow: Hierarchy of Needs - each level of needs must be satisfied before one moves onto the next. Self Actualization- strive to be the best one can. View of cause of disorders: Barriers to self actualization. Ideal self and actual self not in congruence Treatment technique: Client-centered therapy. Self-help, group therapy View on personality : CR said our ideal self must be in congruence with our actual self. View on motivation : Maslow’s hierarchy of needs says basic needs should be met before higher needs Carl Rogers: Focused on the feelings of the client. Unconditional positive regard Fostered a therapeutic approach to therapy. Fully functioning: personal growth, free will, self-determination

23 HUMANISM View of cause of disorders: Barriers to self actualization. Ideal self and actual self not in congruence Treatment technique: Client-centered therapy. Self-help, group therapy View on personality : Our ideal self must be in congruence with our actual self View on motivation : Maslow’s hierarchy of needs says basic needs should be met before higher needs

24 Thoughts impact behavior. “People act because they think.”
COGNITIVE: refers to mental activity including thinking, remembering, problem solving, decision making, learning & using language. Thoughts impact behavior. “People act because they think.” Emphasizes the importance of receiving, storing, and processing information View of cause of disorders : Irrational thoughts lead to anxiety and depression Treatment technique RET, Beck's Cognitive Behavioral Therapy View on personality Based on how we think and perceive the world. View on motivation Based on goals, reducing cognitive dissonance Jean Piaget: identified 4 stages of cognitive development in children

25 COGNITIVE View of cause of disorders : Irrational thoughts lead to anxiety and depression Treatment technique RET, Beck's Cognitive Behavioral Therapy View on personality Based on how we think and perceive the world. View on motivation Based on goals, reducing cognitive dissonance

26 BIOLOGICAL: behavior can be explained in terms of brain structures and biochemical processes that allow organisms to behave. View of cause of disorders Imbalance of neurotransmitters, genetics, hormones, brain structure Treatment technique Drugs and surgery View on personality Genetics, neurotransmitters hormones View on motivation Genetics, neurotransmitters hormones

27 BIOLOGICAL APPROACH View of cause of disorders Imbalance of neurotransmitters, genetics, hormones, brain structure Treatment technique Drugs and surgery View on personality Genetics, neurotransmitters hormones View on motivation Genetics, neurotransmitters hormones

28 SOCIO-CULTURAL APPROACH: Examines the cultural differences in an attempt to understand, predict, and control behavior As time progressed more people were traveling and visiting other cultures Psychologists soon recognized the difference in cultural gestures, body language, and spoken language, etc Lev Vygotsky: those we interact with are responsible for the development of higher order functions. View of cause of disorders Often we mimic our parents or friends’ depression and anxiety. Treatment technique Group therapy View on personality Social Cognitive Theory of Personality View on motivation Compliance and Conformity Language and Color

29 SOCIO-CULTURAL APPROACH
View of cause of disorders: Often we mimic our parents or friends’ depression and anxiety. Treatment technique: Group therapy View on personality: Social Cognitive Theory of Personality View on motivation: Compliance and Conformity

30 Modern extension of functionalism
EVOLUTIONARY: Examines behavioral processes in terms of their adaptive value for members over the course of many generations Modern extension of functionalism Charles Darwin’s theory of evolution by natural selection. Those organisms best suited to their environments will flourish & pass on genes more successfully than those with poorer adaptations. View of cause of disorders Anxiety was a defense mechanism in wild Treatment technique NA View on personality Extroverts maintain social networks View on motivation Instinct and drive theories Criticisms: Untestable Speculative accounts for obvious behavioral phenomena

31 EVOLUTIONARY APPROACH
View of cause of disorders: Anxiety was a defense mechanism in wild Treatment technique: NA View on personality: Extroverts maintain social networks View on motivation: Instinct and drive theories

32 PROMINENCE OF THEORIES
16 14 Cognitive 12 Behavioral 10 Flagship Articles with Keywords (%) 8 Neuroscience 6 4 2 Psychoanalytic Psychoanalysis developed before behaviorism and behaviorism developed before cognitive psychology. The evidence provided on this graph suggests that behaviorism gave way in terms of quantity of published research several decades ago. The graph may not be so helpful when determining psychoanalysis’ impact on the field because psychoanalysts are less likely to be scientists. 1950 1955 1960 1965 1970 1975 1980 1985 1990 1995 2000 2005 Year Intro to Psych Crash Course
