Mistuning of both streams has been associated with psychopathology in mental disorders, including hyperprecise prior beliefs and altered sensory representations. However, empirical research has typically focused on associations between self-report scales and objective physiology during rest or bodily perturbations, without manipulating or measuring descending. Therefore, we developed the novel Adjustment to Interoceptive Discrepancy (AID) paradigm, that builds and then violates interoceptive beliefs to measure expectations and adjustment of expectations over subsequent trials following an unexpected stimulus. We validated this paradigm in the nociceptive domain in a total of 57 university-aged participants. The AID paradigm successfully induced interoceptive discrepancy (<em>i.e.,</em> a difference between expectation and perception ratings) that was resolved as participants adjusted expectations appropriately across subsequent trials. This adjustment was more rapid for stimuli that were perceived as more <em>versus</em> less intense than expected. Notably, there were individual differences in the pattern of this adjustment, revealing different strategies in how individuals adjust to unexpected interoceptive sensations, although these were unrelated to interoceptive sensibility scores. Overall, the AID paradigm provides a useful method to assess interoception across expected <em>versus</em> unexpected stimuli, to probe interindividual differences of interoceptive predictions, and ultimately to enable research on the bidirectional processing of internal stimuli in mental health.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"195 ","pages":"Article 109001"},"PeriodicalIF":2.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143207218","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}

Specifically, meanness-related traits have been linked to deficits in brain reactivity and recognition of facial emotion. Recent meta-analytic work has provided preliminary evidence suggesting that N170 ERP amplitude reductions to fear faces might serve as a neurophysiological marker for meanness traits. However, most of these studies do not examine emotions other than fear, leaving open the question of whether meanness-related alterations in fear face processing might generalize to other facial expressions, nor the role of the other constructs of the triarchic model of psychopathy (i.e., boldness and disinhibition). The current study aimed to address these issues by measuring N170 amplitudes in a mixed-gender sample of 119 undergraduates while they passively viewed a broader range of emotional facial expressions (Anger, Fear, Happiness, and Neutral) alongside control (Scrambled) pictures. The specificity of this association to trait meanness compared to the other triarchic constructs was also assessed. Our results demonstrated meanness-related reductions in N170 amplitudes across all types of facial expressions, not just to fearful faces, even after controlling for the overlap with the other triarchic constructs. These findings highlight a general deficit in the structural encoding of facial features in high mean individuals, emphasizing the potential role of the N170 as a physiological tool for advancing our understanding of the mechanisms contributing to the aggressive, callous, and low-empathic characteristics of psychopathy.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"195 ","pages":"Article 108999"},"PeriodicalIF":2.7,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143207217","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 results showed that relative to curved-shape primes, V-shape primes significantly reduced the illusion strength when the primes were presented with relatively long duration (150 ms) regardless of their eccentricity (4° or 8° from screen center). However, when the primes were displayed with short duration (16.7 ms), significant threat-related modulation effect was only observed with central instead of peripheral presentation. Moreover, the modulation effect vanished with excitation of right dorsolateral prefrontal cortex via intermittent theta burst stimulation.

In Experiment 1 (web-based), younger and older participants read positive and negative target words in positive and negative contexts and rated the valence of the target words. Negative contexts biased the ratings more than positive ones, reflecting a negativity bias during offline valence evaluation in both age groups. In Experiment 2 (EEG), another group of participants read positive and negative target words in positive and negative contexts first, and then the same target words again, and made valence judgment on the target words. OAs showed a larger P2 (180–300 ms) difference before and after contexts for positive target words than younger adults (YAs). This suggests OAs’ early attention to positive features of words in contexts. YAs showed a larger late positive complex (LPC) difference for target words before and after negative contexts than before and after positive contexts, while older adults showed comparable LPC effects across all the conditions. This suggests that YAs use negative contexts to update the affective representation of a word, whereas OAs do so in both positive and negative contexts.

Typically, both external attention and internal attention are vulnerable to biases from intended goals and stimulus features. However, it is still unclear whether the temporal characteristics of the relationship between goal-directed and stimulus-driven external attention could be observed in internal attention. This study aimed to fill this gap by examining whether the lengths of time interval before a recalling probe influenced goal-directed and stimulus-driven internal attention. We manipulated the cue probe interval (CPI) before the probe in a working memory change detection task with a retrospective cue. In addition to behavioral performance, we also traced two electrophysiological signals of the event-related potential (ERP) components of N450 and P300 to represent goal-directed and stimulus-driven internal attention respectively. The results suggested that CPI modulated goal-directed attention with more pronounced N450 amplitudes when CPI was 2000 ms than those when CPI was 500 ms during the informative condition. Meanwhile, more pronounced P300 amplitudes were observed when CPI was 500 ms than those when CPI was 2000 ms for both the matching and nonmatching conditions. Such results lead to the conclusion that internal attention was goal-directed when CPI was as long as 2000 ms, whereas stimulus-driven when CPI is as short as 500 ms.

EEG results revealed a consistent pattern in which the amplitudes of both visual and auditory evoked components decreased following the training. Moreover, a training-specific effect was found for sensory integration, with the effect of audiovisual integration being modulated in the earlier stage of processing for the audiovisual training group.

Understanding how neurocognitive processes modulate attentional biases, such as prolonged attention (overresponding) to threats or avoidance, is crucial for explaining their effects on mental health during the pandemic.
