Abstract

Behavioral ecologists and economists emphasize that potential costs, as well as rewards, influence decision making. Although neuroscientists assume that frontal areas are central to decision making, the evidence is contradictory and the critical region remains unclear. Here it is shown that frontal lobe contributions to cost-benefit decision making can be understood by positing the existence of two independent systems that make decisions about delay and effort costs. Anterior cingulate cortex lesions affected how much effort rats decided to invest for rewards. Orbitofrontal cortical lesions affected how long rats decided to wait for rewards. The pattern of disruption suggested the deficit could be related to impaired associative learning. Impairments of the two systems may underlie apathetic and impulsive choice patterns in neurological and psychiatric illnesses. Although the existence of two systems is not predicted by economic accounts of decision making, our results suggest that delay and effort may exert distinct influences on decision making.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ACC is required for monitoring and prediction of an action-outcome relationship by representing reward-related information such as reward value and cost of action.

    “The ACC is required for monitoring and prediction of an action-outcome relationship30,31, by representing various reward-related information, such as reward value and cost of action32–34.”
  • Rats with orbitofrontal cortex lesions show a similar bias toward immediate rewards.

    “Similar results are seen in rats with lesions of the OFC (Mobini et al., 2002; Rudebeck et al., 2006).”

  • Orbitofrontal cortex moderates impulsive choice and represents subjective value during decision-making.

    “The OFC is thought to moderate impulsive choice (Mobini et al., 2002; Rudebeck et al., 2006), and to represent subjective value during decision-making (Izquierdo et al., 2004; Padoa-Schioppa and Assad, 2006; Roesch and Olson, 2004; Schoenbaum and Roesch, 2005).”

    From Impulsivity, frontal lobes and risk for addiction (2009) · cites this paper as Rudebeck et al., 2006

  • dACC/dmPFC neurons signal the net value of rewards associated with effort.

    “In addition, single-unit studies have shown that dACC/dmPFC neurons signal the net value of rewards associated with effort, and the necessity of this region in cost–benefit valuation has been demonstrated by lesion studies that report that inactivation of medial prefrontal cortex impairs an animal’s ability to overcome effort costs [15, 16, 25, 48, 55].”
  • Controlling the temporal parameters of both the cognitive and physical effort tasks eliminated delay discounting as an explanation of choice behaviour.

    “Third, by controlling the temporal parameters of both the cognitive and physical effort tasks, it was possible to eliminate delay discounting as an explanation of choice behaviour [5, 47, 48].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
