Document Summary

How do neurons (cid:862)work(cid:863): observation, problem: correlation, experiment, between-groups design- easiest to set up, within- groups design- all subjects exposed to all conditions. Self-report- look at scales- how someone feels. Verbal attack- look at people talking to one another and how they feel aggressive (yell, use of words) Threats to validity: internal validity- degree to which experiment supports causal conclusion. More important external validity- degree to which results can be generalized. Demand characteristics: cues in experiment convey hypothesis to participants the(cid:455) (cid:862)help(cid:863) e(cid:454)peri(cid:373)e(cid:374)ter. Geen and berkowitz- if someone was ready to be aggressive, and they saw a weapon, they would become more aggressive because a weapon resembles aggression experimenter expectancy: Intons-peterson- people came into lab and look at a map. There were two conditions, imagery (imagine this) and perception (look at this) condition.
