Psychology • Scientific study of the behavior of individuals and their mental processes • Scientific method-(set of steps) • Behavior (adjustment to environment) • Individual • Mental process (human mind)
Goals • Describe-data, observations, analysis
Goals • Explain-find patterns, why? • Orgasmic: inner determinants of an organism • Dispositional: in human or animal occurrences of organismic variables • Situational or environmental variables: external influence
Goals • Predicting • Scientific vs. Causal • Scientific-relation of events • Casual-condition under change
Goals • Control • starting, stopping, maintaining, strengthening, weakening a behavior
History of Psychology • Socrates, Plato, Aristotle • mind controlled by person, not gods • Dualism (1600) • mind+body separate • Descartes-Mind controls body (1596-1650)
William Wundt (1879) • 1st experimental Psy. Lab • Structuralism • Study of the structure of mind + behavior • All human mental experience can be understood as a combination of simple elements or events • Rejections to structuralism • Reductionism-over simplified • Elemental-did not look at whole • Mentalistic-only verbal human
William James (1890) Functionalism -learned habits that enabled organism to adapt, function and survive in their environment
John Dewey (1920’s) • Founded the school of functionalism
Modern Psychological Approaches • Biological • Focus on genes, brain, nervous and endocrine systems to identify behaviors • Psychodynamic • Driven by powerful inner forces • Unconscious • Freud • Behaviorist • Measurable or observable behavior • Humanistic • People in inherently good, striving for maximum potential • Rogers, Maslow • Cognitive • Stresses human thought • Evolutionary • Mental abilities adapted over millions of years
Psychology • Scientific study of the behavior of individuals and their mental processes • Scientific method-(set of steps) • Behavior (adjustment to environment) • Individual • Mental process (human mind)
Scientific Method • Hypothesis • Test hypothesis • Organize and report on Data • Conclusion
Bias • Due to personal motives, expectations
Standardization • Uniform procedures in treating things in an experiment
Variable • Factor that varies in amount or kind
Independent vs. Dependent • Free to vary vs. acted upon (changes)
Confounding Variable • Stimulus other than the variable an experimenter explicitly introduces
Expectancy Effects • Experimenter manipulates the situation creating expected result.
Control Procedures • Double blind • Keep both assistants + participant unaware • Between Subject designs • Random assignment
Representative Sample • Cannot get everyone take small sample that represents population
Within-subjects design • Use subject as their own control
A-B-A Design • A-baseline • B-treatment • A-Return to Baseline
Correlation Methods • Figure which 2 variables, traits, or attributes are related • correlation coefficient (r) • 1.0 to –1.0
Reliability • Test produces similar scores each time
Validity • Test measures what it is intended to measure
Self Reported Measures • Observe and report one’s own behavior
Behavioral Measures • Overt actions + reactions that are observed + recorded not self reported
Case Study • Intensive study of one or a few
Ethics • Risk vs. Brains • Informed consent • Intentional Deception • Animals
