Abstract

Three experiments with the psychomotor vigilance task examined whether presenting content-free cues, feedback, and points would reduce lapses of sustained attention. In all three experiments, behavioral lapses of attention (particularly slow reaction times) were reduced with the motivation manipulations compared with control conditions, but self-reports of off-task thinking (e.g., mind-wandering) were unaffected. Pupillary responses (preparatory and phasic) also tended to be larger with the different manipulations compared to control conditions. Collectively, the results are consistent with attentional effort models, suggesting that sustained attention was improved and lapses of attention reduced owing to participants in the motivation conditions mobilizing more attentional effort than participants in the control conditions. These results are consistent with recent research, which suggests that the locus coeruleus norepinephrine system is associated with the mobilization of effort.

期刊介绍: Cognitive, Affective, & Behavioral Neuroscience (CABN) offers theoretical, review, and primary research articles on behavior and brain processes in humans. Coverage includes normal function as well as patients with injuries or processes that influence brain function: neurological disorders, including both healthy and disordered aging; and psychiatric disorders such as schizophrenia and depression. CABN is the leading vehicle for strongly psychologically motivated studies of brain–behavior relationships, through the presentation of papers that integrate psychological theory and the conduct and interpretation of the neuroscientific data. The range of topics includes perception, attention, memory, language, problem solving, reasoning, and decision-making; emotional processes, motivation, reward prediction, and affective states; and individual differences in relevant domains, including personality. Cognitive, Affective, & Behavioral Neuroscience is a publication of the Psychonomic Society.
