PSYB04H3 Chapter Notes - Chapter 9: General Linear Model, Thirteenth Grade, Regression Testing
Document Summary
In all three techniques, as in all association studies, the variables are measured that is, none are manipulated. Establishing temporal precedence with longitudinal designs: a longitudinal design can provide evidence for temporal precedence by measuring the same variables in the same people at several points in time. Longitudinal research is used in developmental psychology to study changes in a trait or an ability as a person gets older. Such a pattern indicates that tv preferences lead to aggression over time: the study could have shown the opposite results that aggression at time. 1 was correlated with tv preferences at time 2, but that tv preferences at time 1 were not correlated with aggression at time 2. Such a pattern (cid:449)ould ha(cid:448)e i(cid:374)di(cid:272)ated that the (cid:272)hildre(cid:374)"s aggressi(cid:448)e traits (cid:272)a(cid:373)e first, leading to preferences for violent tv later: a study might show that both correlations are significant.
