The structure of the central executive: Computational and empirical explorations
|Date/Time:||Wednesday 18 January 2012, 4.15pm|
Executive functions are sometimes viewed as control processes that regulate cognition when it is necessary to inhibit a prepotent response or shift task sets. At other times they are viewed as higher level cognitive faculties such as "planning" or "monitoring" which somehow modulate lower level systems. In this talk I will attempt to reconcile these views by presenting two converging lines of work: exploratory findings from computational modeling of executive task performance (for a random generation task and the WCST); and results of recent experimental studies that attempt to fractionate executive functions using a dual task paradigm. Together, this work points towards a novel cognitive architecture in which specific executive functions play central roles, interacting in the generation of complex behaviour.
