However, this process is exaggerated in persons with anxiety disorders, leading to overgeneralization of learned threat associations, hyperreactive fight-or-flight responses, and persistent avoidance. Patients with social anxiety disorder (SAD) exhibit impaired conditioned threat discrimination particularly with respect to social stimuli, such as faces. The present study examined the relationship between social anxiety and generalization of visuocortical and pupil dilation responses to a series of facial morphs, one of which was always paired with a noxious sound. Steady-state visual evoked potentials (ssVEPs; N = 65) exhibited greater fit to a model of generalization, whereas pupil dilation responses (N = 62) exhibited worse CS + discrimination as a function of social anxiety. These results contribute to a growing body of work suggesting that SAD dysregulates the ability of autonomic responses to specifically target social threat. The finding of widened visuocortical tuning in SAD implicates a role of the visual system in driving attentional biases in anxiety disorders, including greater visual processing of safety signals similar to threat cues.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1895-1909"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147655430","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}

We investigated how these responses generalise across different sensory modalities by using transitions between regular and random sequences of visual dots and auditory tones. In Experiment 1, we investigated sequences of visual dots and found that (a) transitions from a regular sequence to a random sequence induced pupil dilations, (b) transitions from one regular sequence to another regular sequence also induced pupil dilations, and (c) transitions from a random sequence to a regular sequence did not reliably induce them. In Experiment 2, we replicated these findings, confirming their reliability and thereby generalizing the literature from the auditory to the visual modality. In Experiment 3, we directly compared pupil dilations in visual and auditory modalities. We observed strong cross-modal similarity in pupil sizes, particularly for transitions between regular and random sequences. We also decomposed the pupil size time series to approximate phasic pupil dilation events. While the patterns of dilation events were quite similar, differences between modalities in dilation size (but not in rates) occurred during transitions from one regular to another regular sequence. Overall, our findings suggest that pupil-linked arousal reflects inference of statistical structure and its violations, exhibiting substantial (albeit not perfect) similarity across modalities.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1684-1705"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13385247/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147634669","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}

However, evidence is inconsistent, and these models do not account for individual differences or differentiate between adaptive and maladaptive risk-taking. More recent theories seek to address these limitations; yet most evidence relies on self-report rather than neural measures of control and reward systems. This study explores cross-sectional and longitudinal relationships between cognitive control and adaptive and maladaptive risk-taking in 15-35-year-olds assessed 2 to 4 years apart (n = 73). Cognitive control was assessed with behavioural and EEG (i.e., switch positivity) measures derived from a cued-trials task-switching paradigm. Risk Adjustment (i.e., adaptive risk-taking) and Impulsivity (i.e. maladaptive risk-taking) were measured using the Cambridge Gambling Task and Information Sampling Task, respectively. Linear mixed-effects models were used to examine relationships between these measures, how they change over time, and the impact of age. Cognitive control and Impulsivity peaked in young adulthood. Risk Adjustment increased slightly over time, but not significantly, and not significantly differ by age. An increase Switch Positivity amplitude from Time 1 to Time 2 was associated with a decrease in Impulsivity, regardless of age. Initial cognitive control did not predict changes in Risk Adjustment or Impulsivity. These findings support models that emphasise individual variability in cognitive control as more accurate predictors of impulsive behaviour than age alone. They also highlight the need for consistent definitions of constructs, such as cognitive control, impulsivity, and risk-taking, across different measurement levels.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1630-1650"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13384997/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147461002","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}

Across two experiments, we examined the balance of proactive and reactive control in the AX-CPT under several negative affect and punishment manipulations. In Experiment 1, we compared cognitive control performance between two task phases: an Affect phase, in which emotionally evocative images were used to induce either Fear, Anger, or Neutral affect; and a Punishment phase, in which the threat of receiving mild electric shocks was either performance-contingent, or noncontingent. In Experiment 2, we examined cognitive control under uncertain, noncontingent punishment, and whether effects of such punishment varied by individual differences in trait anxiety and intolerance of uncertainty. Across both experiments, we observed that threat of punishment was associated with increased proactive control and that this effect was heightened when punishment was performance-contingent. In contrast, punishment uncertainty did not appear to modulate cognitive control outcomes at the group level. However, exploratory analyses suggested that punishment uncertainty might interact with individual variability in trait anxiety, intolerance of uncertainty, and threat-related physiological arousal responses to shape control outcomes. Together, our findings support an account in which punishment motivation might facilitate increased proactive control, similar to prior observations with reward motivation. In contrast, the relationship between negative affect and cognitive control outcomes may be more complex, and vary both with task contextual factors and individual differences in response to threat.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1504-1537"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147318989","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}

In N400-based SMEs, for example, items later remembered elicit less negative N400 amplitudes at encoding compared to items later forgotten. These effects have traditionally been interpreted as reflecting idiosyncratic neural states during encoding-in the case of the N400, states related to semantic activation-that influence episodic encoding success. However, recent work on memorability, a stable, item-level property indicating the population-level likelihood that an image will be remembered, has shown that high (compared to low) memorability images elicit less negative N400 amplitudes, suggesting that memorability is linked to more targeted semantic mapping. This raises the question of whether encoding-related effects are more tied to intrinsic stimulus properties or in-the-moment encoding variability. The present study examined both factors in tandem: ERPs were recorded while participants viewed images varying in memorability and were later classified by recognition outcome (hit vs. miss). Analyses revealed that N400 amplitudes were significantly predicted by memorability scores even when controlling for subsequent memory performance. Memorability also predicted Late Positive Complex SMEs. These findings suggest that neural activity traditionally associated with later memory success may capture item-level properties rather than transient encoding states. Consequently, memorability appears to be a key driver of differences in memory performance, challenging interpretations of SMEs as purely state-dependent and highlighting the importance of considering intrinsic stimulus characteristics when evaluating effects correlated with memory success.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1651-1665"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13385014/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147787624","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}

It extends prior research on deception about attitudes by addressing individual life plans as a more specific and immediate determinant of future behavior. By examining deception about individually planned behaviors, the present study establishes a link to previous forensic research focusing on deception concerning (criminal) behavior. Participants (N = 114) indicated whether they planned certain behaviors. Stimuli were selected individually for each participant. Participants responded more slowly and less accurately for deceptive than truthful responses. Medial frontal negativities (MFNs) were enlarged for deceptive compared to truthful responses, revealing greater response conflicts during lying. Decreased pre-response positivities (PRP) and late positive components (LPCs) for deceptive responses suggested that lies were accompanied by strategic monitoring and were cognitively more demanding, respectively. For all ERP components, the difference between deceptive and truthful responses was greater for planned than for unplanned behavior, revealing that lying about planned behavior was cognitively more challenging. Practice, i.e., repeating the task, did not affect the difference in ERPs between deceptive and truthful responses, indicating that deception did not become less cognitively demanding. The patterns of MFN and LPCs were stable across individual differences in Machiavellianism. The MFN, PRP, and LPC components appear to be promising markers of the additional executive processes involved in lying about individual future life plans. These findings provide a foundation for investigating ERP components during deception also regarding other nonforensic, everyday topics.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1577-1596"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13385121/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147482277","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}

While our previous transcranial magnetic stimulation (TMS) study provided causal evidence indicating that social exclusion significantly impacts the perception of crowd facial expressions, the neural correlates underlying this effect across distinct event-related potential (ERP) components remain poorly understood. To address this issue, the present study used ERPs to extend our neurophysiological insights into this phenomenon. Participants' brain activity was recorded while they performed an emotion discrimination task, viewing happy or disgust crowd faces (Experiment 1) or single faces (Experiment 2) following experiences of social inclusion or exclusion through a Cyberball game. Results from Experiment 1 indicated that social exclusion enhanced neural responses to both happy and disgust crowd faces, evidenced by larger mean amplitudes of the N170 and late positive potential (LPP) components. This neural enhancement was also correlated with greater need threat, as higher levels of need threat were associated with larger neural responses to emotional crowd faces. In contrast, Experiment 2 found no exclusion-related neural effects when participants viewed single faces. These neural results may reconcile the social reconnection hypothesis with the rejection sensitivity model by demonstrating that social exclusion increases responsiveness to socially affective information extracted from groups. In everyday social interactions, this increased responsiveness could influence how people read and evaluate emotional signals in crowds, ultimately affecting social judgment and adaptive behavior.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1851-1866"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147693520","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 aim of the present study was to investigate electrophysiological differences between low CR (LCR) and high CR (HCR) at rest and during the performance of two cognitive control tasks with different difficulty level. Thus, 67 older adults performed an experimental session consisting of two spatial stimulus-response compatibility (SRC) tasks (i.e., the Simon task, and the more demanding spatial Stroop task), and a resting state during an electroencephalogram (EEG) recording. Cognitive control was better in the HCR than in the LCR group, as revealed by higher accuracy in the HCR compared to the LCR group in incongruent conditions of the tasks. Moreover, event-related brain potentials (ERPs) showed earlier latencies (P300) in HCR than LCR and time/frequency analysis showed higher alpha activity in HCR than LCR during the performance of the tasks, while no differences were observed at rest within any of the analyzed frequency bands. Higher P300 frontalization was observed in LCR than HCR in the more difficult task but it was not related to frontalization within a specific frequency band. Overall, results showed that electrophysiological differences between high and low CR depend on the cognitive state, with greater CR-related differences emerging at increased task demands.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1556-1576"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145991569","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}

Conversely, participants driven by conformity motivation showed increased learning signals in regions related to norm compliance when the group norm became clearer, including the mid-cingulate cortex, superior frontal gyrus, and right anterior insular.

Such post-loss risk adjustment is shaped by self-control (SC) and achievement motivation (AM), yet whether and how these two traits interact to influence this adjustment remains unknown, as well as its underlying neural correlates. To address this question, we recruited two independent samples (discovery: N1 = 425; replication: N2 = 182) to ask them undergo the resting-state fMRI scanning, finish the psychological measurements, and Balloon Analogue Risk Task (BART) used to measure post-loss risk adjustment (Kloss). The behavior results showed a significant interaction effect between SC and AM: higher SC predicted greater post-loss risk reduction (lower Kloss), but only among individuals with low AM, indicating that achievement motivation moderates how self-control shapes adaptive reactions to loss. At the neural level, converging voxel-based morphometry and rsFC results revealed an interaction effect between SC and AM in the left putamen along with functional connectivity (FC) between the left putamen and the anterior cingulate cortex (ACC). Moreover, a moderated mediation analysis demonstrated that the left putamen-ACC FC mediated the relationship between SC and Kloss exclusively in low-AM individuals. These effects replicated in the independent sample, underscoring the robustness of the behavior results and the identified function pathway. Collectively, these findings highlight a putamen-ACC circuit through which self-control and achievement motivation jointly influence adaptive post-loss risk adjustment. The results provide novel evidence that SC and AM shape risk-taking behavior through through mechanisms associated with monitoring and processing of conflict signals.","PeriodicalId":50672,"journal":{"name":"Cognitive Affective & Behavioral Neuroscience","volume":" ","pages":"1492-1503"},"PeriodicalIF":3.6,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147522814","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}
