Abstract Background Men and women show differences in sensitivity to reward and punishment, which may impact behavior in health and disease. However, the neural bases of these sex differences remain under-investigated. Here, by combining functional magnetic resonance imaging (fMRI) and a variant of the Monetary Incentive Delay Task (MIDT), we examined sex differences in the neural responses to wins and losses and how individual reward and punishment sensitivity modulates these regional activities. Methods Thirty-sex men and 27 women participated in the fMRI study. We assessed sensitivity to punishment (SP) and sensitivity to reward (SR) with the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). In the MIDT, participants pressed a button to collect reward ($1, 1¢, or nil), with the reaction time window titrated across trials so participants achieved a success rate of approximately 67%. We processed the Imaging data with published routines and evaluated the results with a corrected threshold. Results Women showed higher SP score than men and men showed higher SR score than women. Men relative to women showed higher response to the receipt of dollar or cent reward in bilateral orbitofrontal and visual cortex. Men as compared to women also showed higher response to dollar loss in bilateral orbitofrontal cortex. Further, in whole-brain regressions, women relative to men demonstrated more significant modulation by SP in the neural responses to wins and larger wins, and the sex differences were confirmed by slope tests. Conclusions Together, men showed higher SR and neural sensitivity to both wins, large or small, and losses than women. Individual differences in SP were associated with diminished neural responses to wins and larger wins in women only. These findings highlight how men and women may differ in reward-related brain activations in the MIDT and add to the imaging literature of sex differences in cognitive and affective functions.

Abstract Background Men and women show differences in sensitivity to reward and punishment, which may impact behavior in health and disease. However, the neural bases of these sex differences remain under-investigated. Here, by combining functional magnetic resonance imaging (fMRI) and a Monetary Incentive Delay Task (MIDT), we examined sex differences in the neural responses to monetary wins and losses and how these regional activities vary with individual reward and punishment sensitivity. Methods Sixty-three healthy adults (27 women) participated in the fMRI study with a 3-Tesla scanner. Sensitivity to punishment (SP) and sensitivity to reward (SR) were assessed with the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). In the MIDT, participants pressed a button to collect either $1, 1¢, or nil, with the reaction time window titrated across trials to achieve ~67% success. Imaging data were processed with published routines and evaluated with a corrected threshold. Results The results showed higher SP score in women vs. men and higher SR score in men vs. women. Compared to women, men also showed higher response to the receipt of dollar or cent reward in the medial prefrontal cortex, in the area of the supplementary motor cortex. Regional responses to loss did not show sex differences. Further, in a whole-brain regression, activation of the caudate head during 1¢ loss was correlated positively with SR score in men but not in women, and the sex difference was confirmed by a slope test. Conclusions Together, men showed higher SR and neural sensitivity to the receipt of reward, big or small, than women. Individual differences in SR could be reflected by caudate response to a small loss in men. These findings highlight how men and women may differ in reward-related brain activations in the MIDT and add to the imaging literature of sex differences in cognitive and affective functions.

Sensitivity To Punishment

RationaleGray's theory of personality distinguishes two personality dimensions: Behavioral Activation System (BAS) and Behavioral Inhibition System (BIS). This construct has been widely used in the field of addictions and the study of impulsivity. BIS and BAS can be measured using the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). This questionnaire has been carried out in cross-sectional studies related to alcohol misuse, eating disorders, pathological gambling and cannabis misuse.ObjectivesTo study Sensitivity to Reward and Sensitivity to Punishment as factors that could predict the development of Alcohol Dependence.Methods380 subjects completed the SPSRQ at the beginning of the study and were followed-up for 4 years. At this point, participants completed a protocol that assessed drinking-related variables and drinking patterns. Statistic was performed using regression analysis.ResultsLow scores obtained in the Reward Sensitivity Subscale was a significant predictor for developing an Alcohol Use Disorder (AUD). High scores obtained in the Punishment Sensitivity Subscale were not significantly related to the subsequent development of an AUD.ConclusionsLow scores obtained in the Reward Sensitivity Subscale predict a higher risk for the development of Alcohol Dependence. This could be due to more difficulties that these individuals exhibit, despite the negative consequences, when they have to inhibit their seeking behavior and intake of alcohol.

Postprandial Energy Expenditure

Structural differences in dietary fatty acids modify their rate of oxidation and effect on satiety, endpoints that may influence the development of obesity. This study tests the hypothesis that meals containing fat sources with elevated unsaturated fats will result in greater postprandial energy expenditure, fat oxidation, and satiety than meals containing fats with greater saturation. In a randomized, 5-way crossover design, healthy men and women (n = 23; age: 25.7 ± 6.6 years; BMI: 27.7 ± 3.8 kg/m2) consumed liquid meals containing 30 g of fat from heavy cream (HC), olive oil (OO), sunflower oil (SFO), flaxseed oil (FSO), and fish oil (FO). Energy expenditure and diet-induced thermogenesis (DIT) were determined by metabolic rate over a 240 min postprandial period. Serum concentrations of ghrelin, glucose, insulin, and triacylglycerol (TAG) were assessed. DIT induced by SFO was 5% lower than HC and FO (p = 0.04). Energy expenditure and substrate oxidation did not differ between fat sources. Postprandial TAG concentrations were significantly affected by fat source (p = 0.0001). Varying fat sources by the degree of saturation and PUFA type modified DIT but not satiety responses in normal to obese adult men and women.

Image Variables

The purpose of this study was to explore body image correlates of voluntary consumption of physique-salient media. A secondary aim was to assess changes in affect following media consumption. Young adult men (n = 47; mean age = 20.2 years) and women (n = 87; mean age = 19.5 years) were discretely exposed to images of same-sex models with idealized- and average-physiques while completing an irrelevant computer task. Voluntary gaze at the images was covertly recorded via hidden cameras. Participants also completed measures of affect before and after the computer task. Measures of body-related envy, body appreciation, and self-perceptions of attractiveness, thinness, and physical strength were completed. Men and women did not differ in how often nor for how long they looked at the images overall, but body image variables were differentially associated with their voluntary gaze behaviors. For men, higher body-related envy and lower body appreciation were correlated with more looks at the average-physique model. Although women reported higher body-related envy than men, envy and body appreciation were not significant correlates of gaze behaviors for women. Both men and women experienced a general affective decrease over time, but only for men was the change in negative affect associated with their time spent looking at the ideal-physique image. Overall, these findings suggest that body-related envy and body appreciation influence how men choose to consume physique-salient media, and that media consumption may have negative consequences for post-exposure affect. Body image factors appear to be more strongly associated with behavior in men, perhaps because men are generally less often exposed to physique-salient media and, in particular, to average-physique images.
