Abstract

Individuals' perception of task difficulty (sense of effort) is thought to reflect resource requirements. As task complexity increases, more resources are allocated to a task, and greater effort is experienced. We investigated resource allocation in subjects with brain damage by examining sense of effort during a lexical decision task. Although non-brain-damaged subjects demonstrate strong relationships among task complexity, reaction time, and effort (Clark & Robin, 1994), consistent relationships were not always observed for subjects with CVA or TBI. These data suggest that subjects with brain damage may not be sensitive to task complexity and may require external cues to effectively allocate resources.
