Pupillary responses to a cognitive effort task in schizophrenia

Effort-based decision making paradigms are increasingly utilized to gain insight into the nature of motivation deficits. Although these tasks are being used to assess effort and motivation in schizophrenia, little work has been done to confirm that effort-based decision making tasks validly manipulate effort. In the current study, we adapted the effort component a cognitive effort-based decision making task (the Deck Choice Effort Task) for use with pupillometric assessment. We sought to confirm with psychophysiology that cognitive effort is manipulated.
