Cognitive effort: A neuroeconomic approach

Cognitive effort: A neuroeconomic approach.

Cognitive effort has been implicated in numerous theories regarding normal and aberrant behavior and the physiological response to engagement with demanding tasks. Yet, despite broad interest, no unifying, operational definition of cognitive effort itself has been proposed. Here, we argue that the most intuitive and epistemologically valuable treatment is in terms of effort-based decision-makin...

Measuring Beliefs and Rewards: a Neuroeconomic Approach.

The neurotransmitter dopamine is central to the emerging discipline of neuroeconomics; it is hypothesized to encode the difference between expected and realized rewards and thereby to mediate belief formation and choice. We develop the first formal test of this theory of dopaminergic function, based on a recent axiomatization by Caplin and Dean [2008A]. These tests are satisfied by neural activ...

Impairment of decision-making in multiple sclerosis: A neuroeconomic approach.

OBJECTIVE To assess the decision-making impairment in patients with multiple sclerosis (MS) and how they relate to other cognitive domains. METHODS We performed a cross-sectional analysis in 84 patients with MS, and 21 matched healthy controls using four tasks taken from behavioral economics: (1) risk preferences, (2) choice consistency, (3) delay of gratification, and (4) rate of learning. A...
