Document Summary

Biological foundations: more research design, the neuron, action potential. Research methods: observation, survey, case study, correlation, experiments, between groups design (more costly, but more effective, within groups design. Group 1 watches a violent show and then measure aggression with that group. Group 2 watches non-violent show and then measure aggression. Aggression = dependent variable because it never changes. Violent show = independent variable because it is being manipulated. Group 3 could be a control group to see how people act before called no treatment control . Example: all subjects exposed to all conditions. All watch violent show -> measure aggression. Potential order effect needs to be counterbalanced. Measuring aggression: self-report, verbal attack, physical attack shock test; able to shock the person who attacked you from low shock to high shock. If there is a weapon present in the room, people become more aggressive by just seeing a weapon: experimenter expectancy, experiments conveys hypothesis to participants.
