Psychology
the scientific study of behavior and mental processes which began with philosophers' thinking about thinking, and continuing as the biological/physiological study of the human mind and body.
Structuralism
early school of thought promoted by Wundt and Titchener; used introspection to reveal the STRUCTURE of the human mind
Functionalism
early school of thought promoted by James and influenced by Darwin; explored how mental and behavioral processes FUNCTION- how they enable the organism to adapt, survive, and flourish
Charles Darwin
English natural scientist who formulated a theory of evolution by natural selection (1809-1882)
Sigmund Freud
Austrian neurologist who originated psychoanalysis (1856-1939); Said that human behavior is irrational; behavior is the outcome of conflict between the id (irrational unconscious driven by sexual, aggressive, and pleasure-seeking desires) and ego (rationalizing conscious, what one can do) and superego (ingrained moral values, what one should do).
William James
founder of functionalism; studied how humans use perception to function in our environment
Ivan Pavlov
Russian physiologist who observed conditioned salivary responses in dogs (1849-1936)
Jean Piaget
Four stage theory of cognitive development: 1. sensorimotor, 2. preoperational, 3. concrete operational, and 4. formal operational. He said that the two basic processes work in tandem to achieve cognitive growth-assimilation and accomodation
Carl Rogers
1902-1987; Field: humanistic; Contributions: founded person-centered therapy, theory that emphasizes the unique quality of humans especially their freedom and potential for personal growth, unconditional positive regard, fully functioning person
B. F. Skinner
behaviorism; pioneer in operant conditioning; behavior is based on an organism's reinforcement history; worked with pigeons
Margaret Floy Washburn
Was the first female PhD in psychology. Memory tip: She "washed the burn" of the other early female psychologist who did not earn a PhD (but would probably should have).
John B. Watson
behaviorism; emphasis on external behaviors of people and their reactions on a given situation; famous for Little Albert study in which baby was taught to fear a white rat
Wilhelm Wundt
german physiologist who founded psychology as a formal science; opened first psychology research laboratory in 1879
Gestalt Psychology
a psychological approach that emphasizes that we often perceive the whole rather than the sum of the parts
Edward Bradford Titchener
Structuralist psychologist whose efforts included introspection. This field of psychology failed due to the difficulties in practice, such as a variety of responses by participants.
Mary Calkins
First female president of the APA. Was refused the ability to receive a PhD from Harvard.
Dorothea Dix
A reformer and pioneer in the movement to treat the insane as mentally ill, beginning in the 1820's, she was responsible for improving conditions in jails, poorhouses and insane asylums throughout the U.S. and Canada. She succeeded in persuading many states to assume responsibility for the care of the mentally ill. She served as the Superintendant of Nurses for the Union Army during the Civil War.

positive psychology
the scientific study of optimal human functioning; aims to discover and promote strengths and virtues that enable individuals and communities to thrive
descriptive research methods
Scientific procedures that involve systematically observing behavior in order to describe the relationship among behaviors and events. Can not explain behavior. May show show correlation but not causation.
case study
a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles
naturalistic observation
a descriptive technique of observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation
Hawthorne Effect (Observation Bias)
the behavior of study participants is altered simply because they recognize that they are being studied
survey
a descriptive technique for obtaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group
random sampling
The key technique employed by survey researchers, which operates on the principle that everyone should have an equal probability of being selected for the sample.
interview
A descriptive method in which data is collected via a face-to-face, over the phone, or virtual conversation with researchers and participants
experimental method
A method of investigation used to demonstrate cause-and-effect relationships by purposely manipulating one factor thought to produce change in another factor.

cross-sectional study
a study in which people of different ages are compared with one another
operational definition
a carefully worded statement of the exact procedures used in a research study

dependent variable
The outcome factor; the variable that may change in response to manipulations of the independent variable.
confounding variable
a factor other than the independent variable that might produce an effect in an experiment
control variable
A variable that is kept constant during a controlled experiment.
control group
In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment.
experimental group
In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable.
random assignment
assigning participants to experimental and control conditions by chance, thus minimizing preexisting differences between those assigned to the different groups
placebo effect
experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent.
expectancy effects
the effect that the expectations of others can have on one's self-perception and behavior
placebo effect
experimental results caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent.
Single-blind procedure
research design in which participants don't know whether they are in the experimental or control group
double-blind procedure
an experimental procedure in which both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo. Commonly used in drug-evaluation studies.
statistically significant
an observed effect so large that it would rarely occur by chance
random assignment
assigning participants to experimental and control conditions by chance, thus minimizing preexisting differences between those assigned to the different groups
random selection
A way of ensuring that a sample of people is representative of a population by giving everyone in the population an equal chance of being selected for the sample
validity
the extent to which a test measures or predicts what it is supposed to
Reliability
the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternate forms of the test, or on retesting
Correlation

correlation coefficient
a statistical measure of the extent to which two factors vary together, and thus of how well either factor predicts the other (+ or -)
positive correlation
A correlation where as one variable increases, the other also increases, or as one decreases so does the other. Both variables move in the same direction.
negative correlation
the relationship between two variables in which one variable increases as the other variable decreases
no correlation
there does not appear to be a relationship between two sets of data
