AP Psychology EXAM Flashcards
What perspective?
- depression is caused by a chemical imbalance in the brain, hereditary factors or damaged brain structures
biological perspective
What perspective?
- depression is caused by hidden unconscious conflicts buried deep in the past
psychoanalytic/psychodynamic
Who created the psychoanalytic/psychodynamic perspective?
Sigmund Freud
What perspective?
- a person does depressive behaviors because they learned that it can gain some sort of reward (pity-attention) or they’re imitating someone in their life that modeled this kind of behavior when faced with similar situations
behavioral perspective
Who created the behavioral perspective?
John B. Watson
What perspective?
- one becomes depressed by constantly thinking depressing thoughts, having a negative, pessimistic outlook on life
cognitive perspective
What perspective?
- depression is caused by poverty, poor economic opportunity, alienation, low status
socialcultural perspective
Who created the socialcultural perspective?
Lev Vygotsky
What perspective?
- depression is caused by one not being able to live up to your potential; one feels stifled, kept down, alienated
humanistic perspective
What is the tendency of people to overestimate their ability or predict an outcome that couldn’t have been predicted?
hindsight bias
What type of research method describes behaviors?
descriptive
What type of research method explores relationships between 2 factors?
correlational
What type of research method seeks to prove causation?
experimental
What research method (descriptive)?
- study individual or small group
- focus on unique situations
Strength – helps highlight need for more research
Weakness – highly subjective, not representative of all
case study
What research method (descriptive)?
- polls, consists of questions, random sample
- aims to estimate from a representative sample attitudes/behaviors of whole population
Strength: Data from tons of people
Weakness: lacks depth, wording effect
survey
What research method (descriptive)?
- watching organism in natural habitat
- observer effect
Strength: they do not know they are observed, no interference
Weakness: doesn’t explain behavior
naturalistic observation
What research method (descriptive)?
- study behavior as subject ages
- twins are great for this study
Strength: observation & correlation used, more than one observation done
Weakness: Expensive, takes long time, subject can leave anytime
longitudinal
What research method (descriptive)?
- study how behavior/thoughts vary across different age groups
Strength: Provide data on entire population, can take minimal time to conduct
Weakness: Must control for difference other than age, volunteer bias
cross-sectional
What research method?
- you study something you can’t ethically make someone do, also these studies are conducted after the fact - no random sample
- ‘Quasi-experiment’ (you can’t manipulate the IV)
- Ex. Impact of obesity on financial success, alcoholism on divorce
ex post facto
What type of research?
- measuring the relationship between two factors
- use surveys, naturalistic observations
- correlation does not equal causation
correlational
What is a correlation coefficient?
A statistical measure of the extent to which two factors relate to one another
- range is from -1 to +1
- range gets weaker the closer you get to zero
What is a confounding variable?
prove that A causes B
