The Perception of Available Resources Influences the After-Effect of Cognitive Control on Cognitive Performance and Pain

Abstract

Abstract. In two experiments, we investigated the impact of perceived available cognitive resources using a sequential-task paradigm. First, participants worked on an easy or difficult cognitive task. Then, they received a cue suggesting that their cognitive resources were still optimal or they did not receive any information on their resources. Subsequently, they worked on a second difficult cognitive task (Experiment 1) or received painful electrical stimulations (Experiment 2). We predicted that the cue on optimal resources would neutralize the effect of the first difficult task on subsequent cognitive performance and pain. Overall, results supported our predictions. We interpret these findings as showing an important role of perceived available resources in the after-effect induced by the sequential-task paradigm.
