THE WARMING UP OF ATTENTION: THE INFLUENCE OF COGNITIVE EFFORT ON SIMPLE AND COMPLEX COGNITIVE TASKS


According to the metaphor of mental energy, cognitive resources are strictly limited. Thus, cognitive effort should result in a temporary depletion of available energy. Existing evidence however has proved an opposite cognitive warm-up effect which is characterized by an increase in the availability of cognitive resources as a function of the previous mental effort. The goal of current research is to replicate the discovered phenomenon by using two different measures of available resources. Cognitive effort manipulation (control, moderate and intensive version of DIVA attentional task) followed the selective attention test used to control initial, between-subjects differences in attentional skills and preceded dependent measure which consisted of simple (experiment 1) or complex (experiment 2) cognitive tasks. It was hypothesized that the effect of mobilization of cognitive resources should depend on the insensitivity of cognitive effort manipulation and the complexity of the measure of cognitive resources. Thus, it was expected that cognitive warm-up effect would be stronger after the intensive cognitive effort manipulation and would be revealed by the measure consisting of complex, rather than simple cognitive task. Conducted experiments provided further evidence for cognitive warm-up effect in line with expectations. Alternative explanations of the phenomenon are discussed in terms of the cognitive resources integration, arousal and implicit learning.
