Abstract

Failures of self-regulation are common, leading to many of the most vexing problems facing contemporary society, from overeating and obesity to impulsive sexual behavior and STDs. One reason that people may be prone to engaging in unwanted behaviors is heightened sensitivity to cues related to those behaviors; people may overeat because of hyperresponsiveness to food cues, addicts may relapse following exposure to their drug of choice, and some people might engage in impulsive sexual activity because they are easily aroused by erotic stimuli. An open question is the extent to which individual differences in neural cue reactivity relate to actual behavioral outcomes. Here we show that individual differences in human reward-related brain activity in the nucleus accumbens to food and sexual images predict subsequent weight gain and sexual activity 6 months later. These findings suggest that heightened reward responsivity in the brain to food and sexual cues is associated with indulgence in overeating and sexual activity, respectively, and provide evidence for a common neural mechanism associated with appetitive behaviors.

  • The reaction of the nucleus accumbens to erotic images was predictive of subsequent sexual activity, while the reaction to food cues predicted future obesity.

    “Demos et al. (2012) found that the reaction of the nucleus accumbens to erotic images was predictive of subsequent sexual activity, while the reaction to food cues predicted future obesity.”

    From A motivation model of sex addiction – Relevance to the controversy over the concept (2022) · cites this paper as Demos et al., 2012

    The Abstract reports that nucleus accumbens responses to sexual images predicted sexual activity six months later. Results > Predicting Weight Change reports that responses to food images predicted an increase in BMI, not future obesity; the claim overstates that outcome. (LLM, conf=0.90)

  • Both NAc and vmPFC have been shown to be important predictors of changes in appetitive and self-regulatory behaviors in the real world.

    “both regions have been shown to be important predictors of changes in appetitive and self-regulatory behaviors in the real world [45],[80],[81]”

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.
