Document Summary

Example: researcher a (social cognitive theory) vs researcher b (catharsis theory) Rewrite researcher a"s conclusion tv violence is related to aggression **not increases: causation vs correlation: if there could be another explanation, it"s probably a correlation. Issues with researcher b: small sample groups randomly distributed. In researcher b"s project, the conclusion is more accurate because there aren"t any outlying factors. Correction to researcher b"s project for these participants, under these lab conditions, tv violence decreases aggression: causal, but specific to the conditions. Experimental research (researcher b): tests causal connections, manipulative variables (separate people into groups and give different. Independent variable (iv): the one that is manipulated by the researcher: the cause in a cause and effect relationship, researcher b: amount of violence. Dependent variable (dv): variable affected/changed by the iv: the effect of the outcome, researcher b: the amount of aggression. Example: greater physical attractiveness will create impressions of greater friendliness.
