When little attention was needed to execute the transport task (Experiment 1), precrastination occurred. Also, participants in Experiment 1 who were given an addi- tional cognitive task (memory load) had a higher probability of precrastinating when the far object was at a greater distance than did participants not given the added cognitive task. This outcome suggests that there was a tradeoff between cognitive and physical effort such that increased physical effort was favored when more cognitive effort was required. Moreover, when the transport task was more attention demanding (Experiment 2), precrastination was essentially eliminated. Had precrastination occurred in this case, it would have great- ly increased cognitive effort. Therefore, the results of the sec- ond experiment, taken together with the findings of the first, suggest that physical behavior is structured to reduce cogni- tive effort.
