Correlation approach

examine relationship btw 2 variables. DO NOT manipulate. correlation DOES NOT imply causation.

illusory correlation

relating two variables when they are not related. CORRELATION DOES NOT IMPLY CAUSATION. ex child forms belief that all teachers are nice, when meets a teacher she will automatically trust that person.

negative correlation

- #'s (-1 being perfect) inverse relationship

Characteristics of Naturalistic Observation

1. Non interference: passive observer, no experimental manipulation. 2. Get a "big picture" of a subject- identify patterns. advantages when little is known about a subject. generate new ideas about possible relationships. 3. Study behavior as it unfolds over a period of time or as it occurs at a given time 4. No info about causality, analysis descriptive, not explanatory, does not tell why something occurs.

positive correlation

+ #'s (1 being perfect). as the value of one variable increases so does the other. 2 variables co- vary same direction

Correlation Designs

describe relationship btw 2 or more things (variables). no experimental manipulation- no causation. spawn testable ideas ex. what is the influence of depression on the amount of food consumed in a meal?

Case Study

detailed account of relevant events of one persons life. can study rare events empirically. External Validity e.g. neutral basis of memory loss ex. Kim Peek "trainman"

To Conceal or not Conceal?

people react different when know they are being observed, behavior changes. extreme external validity (+), low internal validity (-). follow behavior as it unfolds over time (+). Qualitative subject judgements (-) ex. gender differences in carrying objects
