Experimental Manipulation of Psychological Control Scenarios: Implications for Exercise and Memory Research

This is the authors' abstract. We don't add key points for this paper.

The purpose of this experiment was to evaluate the extent to which variations in control activities influence memory function, as well as to investigate the participants’ memory expectations for the various conditions. A within-subject, counterbalanced experimental design was employed. Across four visits, participants engaged in four tasks, including an acute exercise session, and three cognitive-engagement control tasks of varying degrees of cognitive engagement and valence, namely reading neutral text, looking at a video, and puzzle completion. Participants’ perceived expectations for how each condition would improve their memory performance was also assessed. We observed no differences in objective cognitive performance or outcome expectations across the three evaluated control tasks, and thus, future studies may wish to employ either of these control tasks, which should not compromise making comparisons across studies.
