Making choices boosts memory, even more so for the unchosen options

Abstract: The current research tested the effects of active choice on memory (i.e., the self-choice effect). Across 14 experiments (N = 1100) we found that memory for choice alternatives was improved by choosing versus being assigned information to remember. A subset of 3 experiments found a bigger self-choice effect for more difficult choices. And a subset of 6 experiments found that prior acts of self-control reduce the self-choice effect. These findings represent unbiased estimates of the self-choice effect (d = 0. 62), the magnitude of the self-choice effect for easy (d = 0.35) versus more difficult (d = 0.87) choices, and the effect of ego depletion on choice memory (d = 0.39). Discussion centers on the role of cognitive control.
