1
The Evolution of Psychology
Psychology- the study of the mind, thinking, and behavior. Psychologists strive to describe, explain, predict, and control behavior **For this power point the important text to copy is red**
2
History of Psychology: Aristotle, before 30 BC
Greek naturalist and philosopher who theorized about learning, memory, motivation, emotion, perception, and personality.
3
René Descartes: Originated the concept of Dualism, viewed mind and body as interactive machines. Stated that the mind could follow body and vice versa. Proposed the idea of both voluntary and involuntary behavior. Ruled out areas other than the brain for mental functioning.
4
John Locke: Knowledge should be acquired by careful observation. No innate ideas: all knowledge comes from experience or reflection. Mind is a blank slate written on by experience (tabula rasa).
5
Dorothea Dix She was shocked and horrified by the treatment of the mentally ill Became a social reformer Spent 40 years lobbying U.S. and Canadian legislators to establish state hospitals for the mentally ill Her efforts directly affected the building of 32 institutions in the United States.
6
Charles Darwin: s Studied the evolution of finches and expands his study to include humans. Opposed religious teachings of the time by suggesting that man was a common ancestor to lower species.
7
Psychology = Eclecticism
Method of utilizing diverse theories and schools of thought to explain human behavior Mosaic, no single approach can create the whole picture. Unlikely that psychology will ever have a one size fits all explanation of human bx
8
Birth of Psychology Wilhelm Wundt: “Father of Psychology”
1879: Leipzig, Germany. Intended to make psychology a reputable science. Many American psychologists eventually went on to study in Leipzig in the 1st Psych Lab
9
Wilhelm Wundt: Father of Psychology
Most of his experiments on sensation and perception. Did not think that high order mental processes could be studied experimentally. Trained in medicine and philosophy. Wrote many books about psychology, philosophy, ethics, and logic.

11
Wilhelm Wundt Wundt’s work led to the 1st school of thought in Psychology called STRUCTURALISM Structuralism - focused on breaking down mental processes into the most basic components. Researchers tried to understand the basic elements of consciousness using a method known as introspection.
12
Introspection Looking inward at one’s own mental processes.
TOOL used to by Structuralist Researchers tried to understand the basic elements of human consciousness using this method
13
E.B. Titchener Wundt’s student. Taught at Cornell University.
Structuralism: He furthered Wundt’s work and understanding of human thought process. Titchener coined term “Structuralism”
14
Margaret Floy Washburn
Student of Edward B. Titchener at the Sage School of Philosophy at Cornell University There she was the first graduate student recommended by Titchener to the Ph.D. program, and became the first woman to obtain her Ph.D. in Psychology in
15
Margaret Floy Washburn
Moved away from Titchener's structural psychology Openly critical of its structuralism later in career - and wrote a second book entitled Movement and Mental Imagery (1917) 1903, she was ranked among the top 50 psychologists in America (when women were excluded from many academic programs)
16
NEXT APPROACH to explain human thinking and behavior
17
William James: 1842-1910 Claimed brain and mind are
constantly changing: focused on function. Began another school of thought called Functionalism: the study of how a mental process operates
18
William James Author of 1st widely used Psych textbook ”Principles of Psychology” 1890 Taught 1st Psych course offered, ever! Expanded psychology to animal behavior.
19
Structuralism to Functionalism (Wundt & Titchener to James and more)
A shift in early schools of thought occurred in Psychology the difference between stopping a train to tear it apart to study its parts (structuralism), and looking at how the systems interact while it is running (functionalism).
20
Mary Whiton Calkins 1863-1930 Studied under William James at Harvard.
Admitted to Harvard as a "guest." Presented Doctoral thesis to Harvard faculty (Despite unanimous approval from the thesis committee) Harvard still refused to grant Calkins the degree she had earned because she was a ____________ ( fill in the blank)
21
Mary Whiton Calkins Is famous in Psychology because:
First woman president of the American Psychological Association Calkins wrote over a hundred professional papers of topics in psychology
22
G. Stanley Hall Functionalist First president of the APA & Founded APA
Established the first psychological lab in the U.S. in 1883 at Johns Hopkins University. Started the American Psychological Journal (1887) now called the American Journal of Psychology, the 1st professional psychological journal
23
WHAT IS THE APA?
24
American Psychological Association (APA)
Founded in 1892 *Largest scientific and professional organization representing psychology in the United States. *Establishes standards of ethics, conduct, education and achievement *Promoting proper research in psychology
25
American Psychological Association
More than 134,000 researchers, educators, clinicians, consultants and students as its members. Mission: is to advance the creation, communication and application of psychological knowledge to benefit society and improve people's lives.
26
NEXT APPROACH
27
Psychodynamic Approach
All behavior is meaningful One’s personality is heavily influenced by the unconscious part of personality Childhood affects adulthood personality
28
Psychodynamic started with Freud
Sigmund Freud, Studied neurology & became a private physician. Became convinced that patients difficulties were due to mental rather than physical problems and that talking it out can ease symptoms Proposed that problems that dated back to childhood.
29
Siggy Freud Psychoanalysis: Freud’s therapy method for treating people with emotional problems Focus on unconscious mind, childhood, dream interpretation and free association, talk therapy His book Interpretation of Dreams, Sold 600 copies in 8 years; today millions are sold every year Freud’s contributions to psychology = talking about problems via counseling sessions
30
Psychoanalytic Theory
3 parts to our Personality: Id: Wants/Desires, Basic primal instincts. “Pleasure Principle”, below our awareness Nearly all of our unconscious impulses are sexual and aggressive in nature. Ego: “Reality Principle” Superego: Conscious mind.“Do the right thing.”
32
Psychoanalytic Theory, more to come in future chapters
Freud’s Psychosexual Stages of Development: Oral (Birth - 1 yr.) Anal (potty training years 2-3) Phallic (3-5 yrs) Latency (puberty) Genital (teen to adult = YOU are here)
33
Psychoanalytic Theory
Freud stated that people are “cesspools of hidden desires.” Unresolved Conflicts: If these occur in childhood, this will cause fixations in later life or use of defense mechanisms
34
More Freud A fixation is a persistent focus on an earlier psychosexual stage Until this conflict is resolved, the individual will remain "stuck" in this stage. For example, a person who is fixated at the oral stage may seek oral stimulation through smoking, drinking, chewing on things or eating.
35
Defense Mechanisms - Freud
Defense mechanisms were created to shield the ego from the conflict of the id and superego (he defined many) Displacement involves taking one’s feelings on a subject out on another, unrelated subject that is less threatening. Rather than argue with your boss, you go home and argues with a sibling.
36
Psychoanalytic Theory: Criticisms
Does not focus on observable behavior Cannot be scientifically proven or disproven Too dark & negative view of human behavior Ignores political and social explanations of people’s problems.
37
Like Freud: “Neo-Freudians”
“Neo-Freudians” – psychologists who agreed with the basis of Freud's psychoanalytic theory, but changed and adapted the theory to incorporate their own beliefs, ideas and theories. Freud proposed a number of ideas that were highly controversial, but also attracted a number of followers.
38
Neo-Freudians & Psychodynamic Approach
Focuses on perceptions, memories & thinking in our unconscious Started with Carl Jung in 1914, breaking from Freud
39
Carl Jung Jung worked with psychiatric patients at the University of Zürich asylum Worked with Freud Jung’s theories revolved around the unconscious mind Eventually, Jung rejected Freud's emphasis on sex as the sole source of behavior motivation
40
Carl Jung Human psyche exists in three parts: the ego (the conscious mind), the personal unconscious and the collective unconscious. collective unconscious was a reservoir of all the experience and knowledge of the human species
41
Alfred Adler 1870 -1937 Austrian, like Freud
Became president of Vienna Psychoanalytic Society Worked with Freud Departed from Freud due in part to his disagreements with aspects of Freud's theories. Played a key role in the development of psychoanalysis with Freud
42
Alfred Adler Believed that every person has a sense of inferiority From childhood people work toward overcoming this inferiority – resulting in self esteem issues Believed that the need to overcome inferiority was the motivating force behind human behaviors, emotions, and thoughts
43
Alfred Adler Broke from Freud and his work with psychoanalysis to begin = “Individual Psychology” Conducted research on effects of birth order on our personality development
44
Adler & Birth Order
45
NEXT APPROACH
46
Behavioral Approach All behavior is observable and measurable Abandoned mentalism for behaviorism All Behavior result of learning
47
Behaviorism-1906 Ivan Pavlov, 1849-1936.
Begins behaviorism Russian experimenter who showed automatic/involuntary behavior in learned responses to specific stimuli in the environment. “Pavlov’s Dogs” Identified“Classical Conditioning.”
48
Behaviorism John Watson, 1913.
Psychology can never be as objective as chemistry or biology. Consciousness is not that easy. “I can take a child and make him into anything, a beggar, a doctor, a thief.”
49
John. B. Watson Baby Albert experiment
Hypothesis- humans learn emotions through classical conditoining Used classical conditioning to teach baby to fear objects (like a white rat)
50
BABY ALBERT by Watson
51
Behaviorism B.F. Skinner, 1950’s.
Dismissed importance of inherited traits and instincts about human behavior Believed that all behavior is a result of rewards and punishments in the past. Any undesired behavior can be modified via reinforcement & punishment
52
SKINNER BOX
53
Another form of a SKINNER BOX
54
B.F. Skinner Used the famous “Skinner Box” as the center of his research Used rats and pigeons studied how we learn, he called it OPERANT conditioning
55

57
NEXT APPROACH
58
Social Learning Theory
Stresses the importance of unique experiences in family, school, community, etc. According to this viewpoint, we learn behaviors through observing and mimicking the behavior of others.
59
Albert Bandura born 1925 Famous Bobo Doll Experiment
We behave because we imitate modeled behavior His criticisms of behaviorists: All behavior cannot be explained by rewards and punishments. Treats people like robots as if they have no free-will.
60
NEXT APPROACH
61
Humanistic Theory (1950-60s)
Strongly disagreed with both Behaviorists and psychoanalysts Stress the importance of people’s feelings and free will Believe humans are naturally positive and seek personal growth People have the ability to heal themselves
63
Humanistic Theory Abraham Maslow: Hierarchy of Needs: People’s struggle is to be the best they possibly can, known as self-actualization. Carl Rogers: Former minister; believed all people strive for perfection; some interrupted by a bad environment.
64
Humanistic Theory Criticisms:
Believes all people are good, when plenty of evidence supports otherwise That people have the ability to heal themselves when there are some biological explanations for mental illness Too vague, more of a philosophy for life than a psychology
65
Next Approach
66
“Biopsych” = Biological Approach
Seeks to understand the nervous system. Believe all human actions & feelings associated with the nervous system Like faulty neurotransmitters causing schizophrenic symptoms, or other mental illness Anatomy & physiology explains human thinking & behavior
67
Biological Approach Many founding Psychologists expected psychology to rest almost solely on Anatomy and Biology. How bodily events interact with events in the external environment to produce perceptions, memory and behavior.
68
Biopsychology Roger Sperry won Nobel-Prize for his Split-Brain research. Weber, Fechner, Helmholtz’s work on complex chemical and biological processes related to sensation and perception (chapter in AP)
69
Contralaterality
70
Biopsychology (Neurobiology)
Criticisms: Ignores mental processes Explains too little of human behavior Rejects environmental influences
71
Next Approach
72
Cognitive Theory Thinking = Cognition
How mental thoughts affect behavior Studies how we attend, perceive, think, remember, solve problems & arrive at beliefs Know what’s going on in people’s heads first, then applies it to their behavior. If Structuralists came back to life (Hall, Titchener, Wundt) they would fit in here!
73
For Example: Cognitivists consider how human memory works to promote learning, like how info transfers from short-term memory and long-term memory Study the physiological processes of sorting and encoding information and events
74
Jean Piaget 1896-1980 Stages of Cognitive Development:
Researched children’s cognitive development Consist if 4 stages Inferred mental processes from observable behavior Children must accomplish mental tasks to prove they advanced to next stage
75
Gestalt Psychology part of cognitive approach
Gestalt Psychology: means “pattern” or “configuration.” Studies how people interpret sensory information in order to acquire knowledge. “The whole is larger than the sum of its parts”
76
Gestalt Psychology School of thought that looks at the human mind and behavior as a whole Started with Max Wertheimer, Gestalt psychology formed partially as a response to the structuralism (Wundt)

NEXT APPROACH
88
Sociocultural Psychology
Examines how cultural and political (religious) experience effect our behavior and thinking Like Gender influences of behavior.
89
Sociocultural Psychology
Stresses the importance of social norms and culture. Proposes that children learn behavior through problem-solving interactions with other children and adults. Through these interactions, they learn the values and norms of their society.
90
Sociocultural Psychology
It is NOT intrapsychic: within the mind or self affecting behavior & thoughts like other approaches It is the outside world affecting our behavior and thoughts
91
Sociocultural Psychology
Criticisms: Makes broad generalizations about ethnic groups and cultures Downplays genetic influences on personality development
92
NEXT APPROACH
93
Evolutionary Approach
Human thinking and behavior are products of natural selection Started with ideas of Charles Darwin Evolutionary psychology postulates the mind and behavior is shaped by pressure to survive and reproduce
94
That is all your approaches
