THE IMPACT OF COGNITIVE LOAD ON THE AVAILABILITY
OF COGNITIVE RESOURCES: THE WARM-UP EFFECT


Abstract. The follow-up effects of cognitive effort on availability of mental energy were
examined. One major prediction was assumed: performing a cognitive task results in
temporary subsequent depletion of cognitive resources ("cognitive depletion"). 72 partici-
pants took part in the experiment. Subjects' attentional abilities were measured to
control initial differences between groups. The cognitive load was manipulated between
subjects by using an attentional task (difficult, easy and control). As a measure of the
cognitive resources' availability (immediately following the cognitive load manipulation)
a random interval generation task was applied. Performance of the subsequent task was
better (more random generation of time intervals) after the difficult and easy
attentional task than after the control version. Further analyses showed that subjects,
who performed the attentional task worse, improved the random interval generation
over time. The results are inconsistent with the predicted cognitive depletion effect, and
they suggest an alternative cognitive warm-up effect.
