PSY 105 Lecture Notes - Lecture 8: Ego Depletion, Psy, Dependent And Independent Variables
Document Summary
Between subjects: focuses on the differences between individuals on a given variable/process participants are assigned to one treatment condition each. Within-subjects: focuses on differences between multiple measurements of a variable within the person; every person gets all of the same measurements as the other participants. Mixed: combines measurement of both between and within person levels. Uses anova (stats test) to examine differences between groups. Uses anova or multiple linear regression to examine effects. One idea is that self-control (e. g. , resisting a temptation) uses energy, so people will be depleted for other tasks (ego- depletion) Purpose of the study: understand the costs of self-control on personal energy.
