AP Psych Unit 1
Ethics in Psychological Research
Protects participants' rights, welfare, and dignity.
Nature vs. Nurture
Debate on the influence of heredity (nature) vs. environment (nurture) on individuals.
Generalizability of Experimental Results
Results may not apply to all humans due to individual and cultural differences.
Scientific Method in Psychology
Systematic approach to studying human behavior and mental processes, with limitations.
Biopsychosocial Approach
Integrates biological, psychological, and social factors to explain human behavior.
Impact of Nature and Nurture
Both significantly influence development and shape personality and behavior.
Ethical Principle in Experimentation
"Do no harm" emphasizes that ends do not justify the means; consent and welfare are paramount.
Psychology Fields

Applied Research: Using research to solve problems
Observation: Watching subjects in their natural environment.
Hypothesis: Testable prediction about the relationship between variables.
Replication: Repeating a study to confirm results.
Variables
Independent Variables: Manipulated factors in an experiment.
Dependent Variables: Measured outcomes affected by independent variables.
Extraneous Variables: Uncontrolled variables that may affect results.
Study Designs
Case Study: In-depth analysis of an individual or group.
Cross-Sectional Studies: Observing different subjects at one point in time.
Longitudinal Studies: Observing the same subjects over a long period.
Statistics
Mean: Average of a data set.
