Abstract

Associating intentions to events that cue future behaviors is a central aspect of human cognition. There is limited understanding of the neural dynamics supporting recognition of intention-related events, with little known about how pre-event brain state varies as a function of intention specificity. Prior to recognized events (that cued planned behavior) occurring during an unrelated activity, we found increased steady-state visual evoked potential (ssVEP) and intrinsic gamma synchronization for ill- compared to well-specified events, as measured by EEG. Enhanced fronto-temporo-parietal ssVEP synchrony emerged preceding ill compared to well-specified events, and the degree of synchrony predicted the completion of ill-specified intentions but predicted failure to complete well-specified intentions. Distinct executive processing and neural states are therefore optimal for anticipating and fulfilling future intentions varying in event specificity.
