Deciding what to do: Observations from a psycho-motor laboratory, including the discovery of pre-crastination

Abstract

A great deal of research has concerned choices of goods or services with different values receivable at various times. Temporal discounting – the magnification of values that can be obtained sooner rather than later – has proven to be immensely important in this regard. In the present article, we shift the focus from the receipt of goods or services to the performance of tasks. We show that temporal discounting also applies to task choices. Pre-crastination, the phenomenon we point to, was discovered by Rosenbaum, Gong, and Potts (2014) and is the tendency to hasten tasks even at the expense of extra energy. Pre-crastination was discovered in a study of psycho-motor performance, where the focus was on biomechanical factors affecting task choices. In the present article, we review that research, showing how the tendency found in the initial experiments are in fact illustrative of a more general motor-control tendency to inhibit easy forms of movement for the sake of later performance goals. Such inhibitory control may also be the basis for pre-crastination, provided one assumes that pre-crastination keeps working memory as clear as possible. A wide range of behavioral choices fit under the rubric of pre-crastination, such as answering emails too soon, submitting articles before they are ready, judging others before they should be judged, convicting others to get cases over with, and, in the worst case, going to war prematurely. Lack of temperance in these choices may seem to arise from impulsivity, but we argue against that view. The desire to “clear the decks” to be prepared for new challenges is, we suggest, a more apt account of pre-crastination.
