Social commitment toward prospective memory tasks in cognitively impaired non-demented individuals

Prospective memory, which is the ability to remember to perform an intended action in the future, has been found to be diminished in cognitively impaired non-demented individuals (CIND). This study investigated whether providing CIND with a social motive would improve their prospective memory performance. Accordingly, CIND and controls were asked to perform a prospective memory task which includes one of the following three conditions: a reward (i.e., a candy bar), no feedback, or a social motive (i.e., that performing the prospective memory task would be a favor for the experimenter). The participants also rated their commitment to achieve the three prospective conditions. Results showed lower prospective memory in CIND than in controls. Unlike controls, CIND did not benefit from the social motive; however, both populations demonstrated commitment toward this condition relative to the “reward” or “control” conditions. Although social motivation did not ameliorate prospective memory, CIND seem to demonstrate commitment to perform prospective memory tasks that involve social benefits for others.
