Food seeking and avoidance are powerful drivers of decision-making in healthy clinical populations. The urge to eat engages primary reward systems the brain, thought bias preference for energy-dense or high-calorie food more likely sate hunger. This process is however interrupted eating disorders where avoided. It nevertheless unclear how innate learned biases may interact with general processing predict learning decisions. We developed a novel paradigm investigate whether high- low-calorie alter large sample participants typical (‘TE’) disordered (‘DE’) behavior. Importantly, characteristics (high- vs. low-calorie) were completely incidental task goal maximizing monetary reward. An arousal manipulation involving win loss, examined heightened arousal, influence goal-directed behavior, enhances impact on learning. Consistent prior notions food-relevant biases, TE group better (i.e., made correct choices) when foods rewarding while DE rewarding. boosted this group-dependent bias. Fitting behavior reinforcement models enabled us identify distinct cognitive components underlying effect. Specifically, food-related was best explained accounting differences initial values rates (for positive prediction errors) foods. In other words, eaters showed their pre-experimental type food, respectively), as well extent which they from outcomes associated that preference. These findings provide mechanistic account reward-based choice, especially under arousal. Our results suggest interventions altering should target habit-directed mechanisms help mitigate maladaptive

Food addiction (FA) is characterized by behavioral changes related to the consumption of palatable foods, marked dependence, impulsivity, and compulsion. Children adolescents are more vulnerable FA owing their significant ultra-processed foods. This review aims investigate differences in dietary intake pediatric populations with without FA. We conducted a systematic literature review. PubMed, ScienceDirect, PsycINFO databases were searched up July 2023. Potentially eligible studies independently checked two researchers. The methodological quality included was assessed using Joanna Briggs Institute Critical Appraisal Checklist for analytical cross-sectional studies. Of 4868 articles identified, six included. All had high quality. High calories fat observed children A diet analysis showed that such as sugary drinks, sweets, chips, Given these findings, we concluded childhood may be associated higher energy and, consequently, macronutrients. Few have examined relationship between food childhood, required.

Food seeking and avoidance engage primary reward systems to drive behavior. It is nevertheless unclear whether innate or learned food biases interact with general processing interfere goal-directed choice. To this end, we recruited a large non-clinical sample of females high eating-disorder symptoms ('HED') matched low ('LED') complete reward-learning task where the calorie content stimuli was incidental goal maximizing monetary reward. We find replicate low-calorie bias in HED high-calorie LED, reflecting strength pre-experimental food-reward associations. An emotional arousal manipulation shifts group-dependent across individual differences, interoceptive awareness predicting change. Reinforcement-learning models further identify distinct cognitive components supporting these group-specific biases. Our results highlight influence reinforcement-based mechanisms eliciting potentially maladaptive Disordered eating can disrupt rewarding value food. Here, authors show female that disorder symptoms, arousal, modulate goal-irrelevant during reinforcement learning.

Abstract The orexin (also known as hypocretin) system, consisting of neuropeptides orexin‐A and orexin‐B, was discovered over 25 years ago immediately identified a central regulator sleep wakefulness. These peptides interact with two G‐protein coupled receptors, 1 (OX ) 2 receptors which are capable coupling to all heterotrimeric subfamilies, but primarily transduce increases in calcium signalling. Orexin neurons regulated by variety transmitter systems environmental stimuli that signal reward availability, including food drug related cues. also activated anticipation, stress, cues predicting motivationally relevant information, those drugs abuse, engage neuromodulatory systems, dopamine the ventral tegmental area (VTA) respond these signals. As such, have been characterized motivational activators coordinate range functions, feeding arousal, allow individual critical for survival. This review focuses on role orexins appetitive motivation highlights pathologies inappropriately high levels motivated arousal (overeating, anxiety substance use disorders) versus is impaired (depression).
