The neurobiological underpinnings of this ability are largely unspecified. This review combines insights from reinforcement learning, predictive coding, and the function of dopamine and norepinephrine to explore the viability of an effortful and error-driven system of adaptation during speech perception. Iteration, internal monitoring, error generation, and prediction are shared across multiple models of adaptation, leading to the possibility of a common mechanism. In search of this mechanism, I consider the role of error signaling within a domain-general account of perceptual adaptation. Drawing heavily from work in the neurobiology of reinforcement learning and effort, I theorize that adaptation during speech perception may be mediated by reward prediction errors wherein successful comprehension may act as its own reward. However, reward prediction error alone is likely insufficient to capture the full dynamics of rapid adaptation. I further propose that the system also leverages norepinephrine signaling to push the listener into an arousal state that allows for rapid perceptual fine-tuning. Ultimately, I argue that complementary, and parallel, error signals originating from multiple subcortical nuclei may direct effortful adaptation during challenges to speech perception.</p>","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiences of ostracism increase vulnerability to psychopathology. Emotion regulation, supported by executive functions, may buffer these effects. However, prior research has mainly examined how ostracism impacts executive functioning, not the reverse. This study tested whether individual differences in inhibitory control, a key component of executive function, modulate neural and psychological responses to ostracism. Forty-two college students (age: 20.6 ± 2.0) completed multi-echo fMRI scanning, first performing a color-word Stroop task followed by the Cyberball task. Greater Stroop interference correlated with heightened activation in presupplementary motor area (pSMA) and dorsolateral prefrontal cortex (dlPFC). Using these signals as covariates in Cyberball analyses, we found that greater inhibitory inefficiency in pSMA coincided with reduced recruitment of the fronto-striatal regions implicated in emotion regulation and social monitoring, including dlPFC, dorsomedial PFC, and caudate nucleus, during ostracism. Notably, we modeled Cyberball by ball-tossing events, allowing us to see that within the Inclusion Block, individuals with inefficient inhibitory control in pSMA, elicited greater activation in these regions while watching others toss to each other vs. including the participant. This association was reversed in the Ostracism Block, where exclusion was explicit and sustained. This pattern suggests that inefficient inhibitory control may correlate with over-engagement of regulatory and social-monitoring systems in response to ambiguous cues of exclusion, followed by disengagement during actual ostracism. These neural patterns were associated with greater self-reported distress, suggesting that inhibitory inefficiency may increase vulnerability to the emotional consequences of social exclusion.</p>","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145226285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This linguistic manipulation allowed us to examine comprehension under conditions when shallow processing and deeper processing yield conflicting meaning representations, which previous work has shown often engages revision and updating processes upon detection of the conflict. A different pattern of event-related potential responses was elicited when the same participants encountered implausible thematic roles during reading after receiving Sham compared with PFC-targeted tDCS. Specifically, N400 effects were found after Sham tDCS, whereas robust P600 effects were found after PFC-targeted tDCS (and to a significantly lesser extent, after Active Control tDCS). This suggests that while readers tended to treat implausible thematic roles as semantic anomalies after Sham tDCS, those same readers were more likely to detect conflict and engage in revision and updating in response to implausible thematic roles when in a state of heightened PFC stimulation.

Participants performed a reinforcement learning task in which the trade-off between using social and nonsocial information affected task performance and the associated monetary reward.

This did not affect the preference for one information source and the risk taken to obtain a high reward. Furthermore, midfrontal theta power was negatively linked to levels of psychopathic traits, aligning with indications that theta is involved in volatility tracking of social information. Importantly, we consider that the task design may reflect reduced sensitivity to secondary, rather than specifically social information.

Depending on the stimulation, we discovered that the cognitive appraisal significantly influenced rumination, positive and negative affect specifically in stress recovery. More precisely, as expected, individuals who perceived greater control experienced a faster recovery of stress-reactive ruminative thinking following sTBS and lower rumination following the stressor. We found lower increases and faster recovery of negative affect in all stimulation conditions and faster decreases in positive affect after the TSST following cTBS and iTBS, suggesting beneficial effects of both stimulation conditions. Concerning the assessed physiological variables, namely heart rate, heart rate variability, and salivary cortisol, we did not observe any impact of appraisal. These findings suggest that the effect of secondary appraisal on psychological variables depends on the type of stimulation, and while it may be linked to increased DLPFC activity, further research is needed to clarify the neurostimulation mechanisms involved.</p>","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1400-1418"},"PeriodicalIF":2.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12464076/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144477729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
