The cone of direct gaze (CoDG) refers to the range within which an observer perceives a gaze as looking directly at them. Previous research has demonstrated that self-relevant exteroceptive cues can widen the CoDG. However, the effect of self-relevant interoceptive information on the CoDG remains unknown. This study investigated the contribution of cardiac afferent signals and vagal tone to the perception of gaze from others. We used a modified gaze discrimination task to synchronize face stimuli with various gaze directions to specific phases of the cardiac cycle. Results revealed that participants with higher heart rate variability (HRV) exhibited a wider CoDG during cardiac systole (when cardiac signals are maximally represented in the brain). However, no effect was observed during cardiac diastole (when cardiac signals are quiescent). Moreover, this effect was independent of individual differences in anxiety levels and autistic traits. These findings are evidence that individuals with greater cardiac vagal control are more sensitive to cardiac afferent signals during systole, which leads to a stronger self-directed perception of others' gaze under transient and ambiguous gaze perception conditions. Our findings highlight the self-referential role of cardiac interoceptive signals in gaze perception and expand our knowledge of interoceptive influences on social judgment.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"212 ","pages":"Article 112564"},"PeriodicalIF":2.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent insights into the facilitatory role of parasympathetic arousal for threat coping have raised the question whether individual differences in sympathetic versus parasympathetic dominance during threat learning may shed light on the complex relationship with anxiety vulnerability versus resilience. We applied an established differential-cue delay threat conditioning paradigm in 78 neurotypical individuals and assessed parasympathetic responses (threat-induced bradycardia), as well as sympathetic responses (threat-induced tachycardia and increased skin conductance responses-SCR). We found evidence that patterns of threat-induced bradycardia as well as tachycardia are present during associative learning. Threat bradycardia was linked to weaker initial conditioned SCRs (mainly driven by responses to the CS+), a finding that may be relevant for current common practice in the field of threat learning: namely participants with weak differential skin conductance responses - who according to frequently applied ‘SCR non-learner’ criteria are often considered non-learners and sometimes even excluded from analyses - were in fact showing successful learning in terms of parasympathetic arousal. Additionally, the <em>presence</em> of threat bradycardia as well as the <em>magnitude</em> of overall conditioned heart rate responses were linked to relatively lower trait anxiety.

An objective, simple method is needed. Dual-tasking, combined with brain function measurements, may provide sufficient cognitive cost to differentiate between healthy and cognitively impaired populations. It was hypothesized that low complexity (entropy) of brain activity is associated with cognitive impairment, and that dual-tasking would better differentiate between healthy and cognitively impaired groups over resting. Eighty-three participants were recruited: healthy young adults (HY; MoCA = 27.82 ± 1.63, age = 21.13 ± 2.36), cognitively normal older adults (CN; MoCA = 26.59 ± 1.92, age = 75.89 ± 6.93), and mild cognitively impaired/early-stage Alzheimer's disease older adults (MCI/AD; MoCA =18.96 ± 5.69, age = 78.62 ± 8.54). Functional near-infrared spectroscopy (fNIRS) measured brain activity during a rest and dual-task involving flexion and serial subtraction. The area under the curve (AUC) of multiple scale entropy outcomes was averaged by functional brain regions: dorsolateral prefrontal cortex (dlPFC), anterior prefrontal cortex (aPFC), front eye fields, motor, visuomotor, and primary sensory. During dual-tasking, the average AUC values across all fNIRS channels were 75.02 ± 12.51, 61.44 ± 14.60 and 42.26 ± 22.89 for HY, CN, and MCI/AD groups, respectively. During dual-tasking, differences between AUC values of CN and MCI/AD groups were significant for the average across all channels, primary sensory, aPFC, and dlPFC regions (<em>p</em> &lt; 0.05). During rest, only the average across all channels was significantly different between CN and MCI/AD groups (<em>p</em> = 0.02).

Some articles emphasized the link between the aforementioned processes and learning outcomes. The following psychophysiological correlates of processes underlying learning interaction were indicated. Inter-brain synchronization in the prefrontal cortex and temporal-parietal area is associated with the social component of learning interactions and positively correlates with learning outcomes. Students’ engagement is accompanied by a decrease in electroencephalography occipital alpha rhythm, indicating heightened attention. Experienced teachers tend to focus their gaze on students while balancing gaze between learners and content facilitates students’ attention. Students’ gaze allocation toward learning-related areas indicates attention and engagement, which varies with instructional strategies. Heart rate and electrodermal activity positively correlate with learners’ engagement, increasing during active educational strategies and decreasing throughout the lesson.
