Psych lecture 5 september 24 2015 scan pg. Dr. jung argues that increases in temperature cause increase in aggression.

His claim is inaccurate because the data was correlational. Does tv violence cause aggression: observation (compare what tv people watch and how aggressive they are) Between- groups design: independent group 1 watch violent show measure aggression (dependent, independent group 2 watch nonviolent show measure. Aggression (dependent: impendent group 3 no tv (control) measure aggression (dependent) Within group design: all violent shows measure aggression, all watch non violent shows measure aggression, potential order effect (order of experiments change results) need to counterbalance, measuring aggression. Internal validity: degree to which experiment supports causal conclusion. External validity: degree to which results can be generalized. Demand characteristics: cues in experiment convey hypothesis to participants, they help experimenter, geen and berkowitz (1967)
