Yet, they can also lead to inflexibility, preventing individuals from adapting to environmental changes. Since it has been difficult to examine habit formation in humans with traditional outcome devaluation paradigms, we applied a motor sequence learning task (MSLT) to study this process. Thirty-one participants (16 female, 28.4 ± 5.3 years old) completed the MSLT on two consecutive days. They implicitly learned to execute a 12-item motor sequence using four fingers, each corresponding to one of four distinct visual stimulus locations. Test blocks introduced sequence deviations by intermittently omitting one item of the sequence. We measured whether participants were able to flexibly adapt their behavior or would incorrectly execute the omitted response - a so-called action slip. Action slips serve as an indicator of automatization or behavioral inflexibility. Findings indicate that prolonged training led to faster response times and lower error rates in learning compared to random blocks, suggesting successful sequence learning and the emergence of automatic behaviors. Action slips increased with extensive training, demonstrating the shift towards automatic and inflexible responding, indicative of habit formation. The results highlight the utility of the MSLT in studying habit formation in humans and emphasize the role of extensive training, motor skills, and automaticity. The task offers a promising framework for investigating the neural and cognitive mechanisms underlying habitual behavior, providing new insights into the balance between habitual and goal-directed control.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144049403","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}

The fusiform face area (FFA) (Kanwisher et al., The Journal of Neuroscience: The Official Journal of the Society for Neuroscience, 17, 4302-4311, 1997) in the inferior temporal lobe is defined by its face selectivity, and the CT of the FFA correlates with the ability to make difficult visual decisions (Bi et al., Current Biology, 24, 222-227, 2014; McGugin et al., Journal of Cognitive Neuroscience, 28, 282-294, 2016, Journal of Cognitive Neuroscience, 32, 1316-1329, 2020). In McGugin et al. Journal of Cognitive Neuroscience, 32, 1316-1329, (2020), individuals with better face recognition had relatively thinner FFAs, whereas those with better car recognition had thicker FFAs. This opposite correlation effect (OCE) for faces and cars was pronounced when we look selectively at the deepest laminar subdivision of the FFA. The OCE is thought to arise because car and face recognition abilities are fine-tuned by experience during different developmental periods. Given autism's impact on face recognition development, we predicted the OCE would not appear in autistic individuals. Our results replicate the OCE in total FFA thickness and in deep layers in neurotypical adults. Importantly, we find a significant reduction of these effects in adults with autism. This supports the idea that the OCE observed in neurotypical adults has a developmental basis. The abnormal OCE in autism is specific to the right FFA, suggesting that group differences depend on local specialization of the FFA, which did not occur in autistic individuals.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057240","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}

Autonomic arousal is thought to modulate these processes, influencing both the readiness and execution phases of actions. This study explores the effects of motor imagery-based mental training on reactive inhibitory control and its correlation with autonomic activity. In Experiment 1, 20 healthy participants completed a stop-signal task to enable the evaluation of motor response performance. The results showed that mental training led to significant improvements in overall response speed and stop-signal reaction time, indicating enhanced reactive inhibition, particularly during the diastolic phase. This suggests an interaction between training effects and the cardiac cycle. In Experiment 2, 20 healthy participants performed an alertness task with two foreperiods (650 ms and 710 ms) to enable the assessment of response timing with different preparatory intervals. Mental training significantly improved response timing during the longer foreperiod, and this enhancement correlated with increased parasympathetic activity. Similarly, an improvement in the suppression of premature responses was observed during the shorter foreperiod, although it did not reach statistical significance after correction. A significant reduction in omission rates in trials without foreperiods was also found. These findings suggest an association between mental training, temporal preparation, and autonomic modulation. However, further research is needed to determine the nature of this relationship and its underlying mechanisms.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144057239","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}

Drawing on studies exploring how mood affects information processing, we propose a mechanistic theory of belief updating in depression. First, we show how depressive beliefs are formed in environments where negative stimuli are weighted more heavily. Second, we demonstrate how depressed individuals often hold rigid negative metacognitive priors that inhibit belief updating. Third, we clarify how negative beliefs can be generated internally through repetitive, self-focused cognitive patterns. Finally, we critically examine the limitations of current experimental paradigms used to assess belief updating, highlighting methodological constraints and potential confounds. Based on these insights, we outline future research directions to refine experimental designs and improve our understanding of mood-congruent belief updating in depression.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144055652","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}

Neurobiological characteristics can influence reactivity to social cues (e.g., perceived liking or rejection) and suicide risk. These effects are exacerbated during adolescence-a developmental period of heightened sensitivity to social contexts. In this cross-sectional study of youth at varying psychiatric risk, we examined whether neural reactivity to social cues moderated the link between sexual minority status and suicidal ideation (SI) and whether sexual orientation victimization experiences further influenced these effects. Seventy-five youth (aged 14-22 years; 52% SMY, 48% heterosexual) reported depression, SI, and victimization, and completed a functional magnetic resonance imaging task involving viewing of unfamiliar face stimuli and receipt of social cues in rewarding and ambiguous contexts. Regions-of-interest analyses examined task-related neural reactivity in neural social regions. Moderation analyses were conducted using linear regressions. Sexual minority youth reported more severe depression, victimization, and SI (p < .05). Left temporoparietal junction (TPJ) activation to social cues, regardless of the degree of valence and certainty, moderated the link between sexual minority status and SI, where SMY (vs. non-SMY) with dampened left TPJ activity had higher SI. Exploratory analyses indicated that these associations were not further influenced by victimization. Results indicate enhanced suicide risk in SMY with altered social processing in the TPJ-a key region of neural social systems-across contexts, regardless of victimization history. Findings suggest that individual differences in neural reactivity to social cues are critical for understanding SMY suicide risk and have potentially important clinical implications.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144054213","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}

Impaired affective decision-making on risk-taking tasks has been reported in individuals with dementia, but the neural correlates of such deficits, and whether they relate to neuropsychiatric symptoms, such as disinhibition and apathy, have not been directly examined.Methods: Forty-one behavioural-variant frontotemporal dementia (bvFTD), 28 Alzheimer's disease (AD) patients and 42 healthy controls completed the Balloon Analogue Risk Task (BART), which assessed their ability to weigh risks versus rewards to maximise monetary earnings. Informant-reported measures of disinhibition and apathy were completed. All participants underwent structural magnetic resonance imaging brain scans.Results: While bvFTD and AD patients showed some impairments on the BART relative to controls, a high degree of variability was observed within patient groups. Poorer BART performance was associated with bilateral medial prefrontal and orbitofrontal cortex atrophy. A hierarchical cluster analysis revealed four groups of patients, with distinct patterns of BART performance, varying levels of disinhibition and apathy, and divergent patterns of brain atrophy. The group that showed the worst performance on the BART (i.e., collected the least money and popped the most balloons) showed the greatest disinhibition and orbitofrontal cortex atrophy.Conclusions: Our findings highlight the heterogeneous nature of affective decision-making deficits in dementia and uncover important links between BART performance, symptoms of disinhibition and apathy, and orbitofrontal cortex atrophy. Greater understanding of these symptom profiles and underlying neurocognitive mechanisms may help to inform potential management strategies for impaired affective decision-making in dementia.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144020181","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}

To address this issue, we assessed the effect of bi-hemispheric prefrontal tDCS in 76 healthy adults with a cross-over, double-blind, sham-controlled design. Half of the participants received the anodal stimulation over the right dlPFC and the cathodal stimulation over the left dlPFC (right anodal/left cathodal; Experiment 1), whereas the other half received the anodal stimulation over the left dlPFC and the cathodal stimulation over the right dlPFC (right cathodal/left anodal; Experiment 2). During tDCS, participants underwent the Point Subtraction Aggression Paradigm. All participants were also given self-report questionnaires measuring individual levels of aggression, impulsivity, and empathy to test whether these constructs were associated with the neuromodulation of aggressive responses at the Point Subtraction Aggression Paradigm. Results show a significant increase in aggressive reactions to provocation during right anodal/left cathodal prefrontal tDCS only within males, highlighting a sex-specific effect of the prefrontal neuromodulation that is also associated with individual levels of aggression. These findings provide a new insight into the brain mechanisms that regulate aggressiveness, their sex differences, and their association with dispositional aggressive tendencies.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144054793","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}

While virtual reality (VR) is used to approximate real-life features in experimental settings, this approach fundamentally hinges on whether the distinct modalities are processed in a similar way. To examine which stages of early visual processing depend on modality-specific characteristics, our study compares the electrophysiological responses to 2D (PC), VR, and real-life (RL) objects. To this end, participants passively explored abstract objects in one of these modalities followed by active exploration in a delayed matching-to-sample-task. Our results indicate that all modalities fundamentally yield comparable visual processes. Remarkably, our RL setup evoked the P1-N1-P2 complex corresponding to the well-established ERP morphology. However, the magnitude of the ERP response during real-life visual processing was more comparable to the response to VR than to PC. Indicating effects of stereoscopy on the earliest processing stages, the P1 differentiated only between PC and RL, and the N1 differentiated PC from both other conditions. In contrast, the P2 distinguished VR from both other conditions, which potentially indicated stereoscopic visual fatigue. Complementary analysis of the alpha-band response revealed higher attentional demands in response to PC and VR compared with RL, ruling out that the ERP-based results are exclusively driven by attentional effects. Whereas comparable fundamental processes are likely occurring under all modalities, our study advises the use of VR if the processes' magnitude is of relevance, emphasizing its value to approximate real-life visual processing.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143812778","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}

Thus, we 1) explored neural underpinnings of individual choice, affective ratings, aggregate outcomes, 2) examined how the above-mentioned measures predict individual and aggregate choices on mobile games, and 3) tested the moderation effect of IS by comparing the differences in how these measures perform in prediction models between subgroups of IS. Neuroimaging results showed that individual choice associated with NAcc activity, aggregate download rate tracked by regions in salience network, and revenue additionally tracked by regions in motor tendency and attention regulation. Affective ratings and AIns activity predicted individual download choice; mPFC activity forecasted aggregate download rate, and positive arousal forecasted aggregate revenue. As hypothesized, the high IS group displayed coherent correlations between affective ratings, individual choice, and neural measures. More importantly, at the aggregate level, mPFC activity (integrative component), forecasted aggregate download rate above and beyond ratings and individual choice in the high IS group, with this prediction significantly stronger compared with the low IS group.

However, there is currently no direct evidence to suggest that pre-choice activity influences value-based decisions that require self-control. We examined the impact of fluctuations in pre-choice activity in key regions of the reward system on self-control in food choice. In the functional magnetic resonance imaging (fMRI) scanner, 49 participants made 120 food choices that required self-control in high and low working memory load conditions. The task was designed to ensure that participants were cognitively engaged and not thinking about upcoming choices. We defined self-control success as choosing a food item that was healthier over one that was tastier. The brain regions of interest (ROIs) were the ventral tegmental area (VTA), putamen, nucleus accumbens (NAc), and caudate nucleus. For each participant and condition, we calculated the mean activity in the 3-s interval preceding the presentation of food stimuli in successful and failed self-control trials. These activities were then used as predictors of self-control success in a fixed-effects logistic regression model. The results indicate that increased pre-choice VTA activity was linked to a higher probability of self-control success in a subsequent food-choice task within the low-load condition, but not in the high-load condition. We posit that pre-choice fluctuations in VTA activity change the reference point for immediate (taste) reward evaluation, which may explain our finding. This suggests that the neural context of decisions may be a key factor influencing human behavior.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"387-401"},"PeriodicalIF":2.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11906498/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142394952","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}
