While IAcc measures the correspondence between recorded and perceived heartbeats, IS means the confidence in interoceptive perceptions during the task. The present study investigated if brain activity during the heartbeat tracking task is associated with IAcc as well as IS. Specifically, we were interested if task-related power (TRP) in the alpha band (8-12 Hz), known to indicate task-specific cognitive functions such as semantic, attentional, and sensory processes, is associated with IAcc and IS, respectively. In a sample of 30 participants, we found relatively higher TRP in the alpha band over left temporal and parietal areas (vs. right) during the interoception task. Furthermore, we observed a negative association between TRP in the alpha band and IS. Lower TRP in the alpha band might indicate that more pronounced cognitive and sensory processes are linked to higher IS. Furthermore, we found a positive effect for IAcc (independent from IS), which might indicate that more internal attention during the interoception task is beneficial for IAcc. We further discuss the findings in the context of methodological issues of the heartbeat tracking task. Taken together, the pattern of findings favors the investigation of task-related IS (i.e., confidence ratings) in combination with IAcc to gain a better access to interoceptive processes and to improve our understanding of the neural underpinnings of (cardiac) interoception.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70051"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11962349/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research using laboratory models of fear learning offers valuable insights on etiology. In this study, the influence of genetic and environmental etiology of baseline startle response and fear learning was examined, focusing on fear acquisition and generalization processes using the fear conditioning paradigm measuring fear-potentiated startle (FPS) in a sample of adolescents and young adult twins (15-20 years old). Participants (N = 794) completed fear acquisition and generalization training that consisted of quasi-randomly presented rings of gradually increasing size. The extreme sizes served as conditioned danger cues (CS+) paired with electric shock as the unconditioned stimulus and conditioned safety cues (CS-), with rings of intermediary size serving as generalization stimuli. As an index of fear learning, FPS was measured using the magnitude of eyeblink startle reflex to a sound probe. Twin model estimates indicated that both pre-acquisition startle (startle probe responses to stimuli prior to conditioning) and FPS (startle probe responses after conditioning during acquisition and generalization) exhibited modest to moderate heritability (26%-43%), aligning with previous studies on FPS. We also observed that the genetic influences on FPS were highly correlated with pre-acquisition startle, indicating minimal genetic innovation on FPS. This finding implies that fear responses might be regulated, from a genetic perspective, by general startle response as opposed to specific fear-learning-related factors. We discuss the resulting implications for measurement of biomarkers for fear and anxiety disorders.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70052"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11968083/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143765066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anxiety sensitivity (AS) and intolerance of uncertainty (IU) are cognitive factors in GAD vulnerability that may be activated by negative stimuli, thereby explaining why the LPP and GAD symptoms are related. We examined whether AS and IU explain the association of the LPP with GAD symptoms. Eighty-seven (77% women) young adults viewed 60 negative and 60 neutral images. The LPP was examined using both frequentist and Bayesian approaches. This revealed unique indirect effects of the LPP on GAD symptoms through AS and IU. Neither indirect effect was stronger, and the indirect effects were present regardless of using frequentist or Bayesian analyses or quantifying the LPP using residual-based scores or difference scores. The indirect effects predicted not only GAD symptoms but social anxiety and depression as well, consistent with the role of AS and IU in transdiagnostic vulnerability. The findings support AS and IU as links that explain how attention to negative stimuli is related not only to GAD symptoms but to other internalizing symptoms as well.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70044"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143773112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sleep disturbance and reduced heart rate variability (HRV) have been typically observed in adolescents with MDD. This study aimed to develop an automatic classification model based on nocturnal HRV features to identify adolescent MDD. Sixty-three subjects, including depressed adolescents and healthy controls, participated in the study and completed a three-night sleep electrocardiogram (ECG) monitoring, yielding 160 overnight RR interval time series and 7520 5-min short-term segments for analysis. Nineteen HRV features were extracted from the time domain, frequency domain, and nonlinear dynamics. The Bayesian-optimized random forest (BO-RF) algorithm was applied as the classifier, with performance evaluated using ten-fold cross-validation. The impact of data accumulation on the reliability of identification using short-term data and the importance of features were also examined. The BO-RF classifier based on long-term features achieved a noteworthy predictive accuracy of 80.6%, and the performance of the classifier using short-term data showed a significant improvement when more segment outcomes from the same night were included, ultimately achieving an accuracy of 75.0%. The Poincaré plot-derived features, especially heart rate asymmetry (HRA) features such as C1d, significantly contributed to distinguishing depressed adolescents from healthy subjects. Nocturnal HRV features can effectively differentiate adolescents with MDD from healthy controls. This study provides a promising diagnostic approach for adolescent MDD, with the potential to be integrated into wearable devices for broader application.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70049"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Together they suggest that self-regulatory effort and positive social experiences may lead to short-term increases in RSA, which in turn are related to adaptive emotional, social, and physical functioning. However, the extant literature on adult social interactions does not clearly support this premise. To study the connections between dyadic social interactions and phasic changes in RSA, the current research examined 356 dyads (712 adults between 18 and 36 years; 50% males, 50% females) across three studies in which participants engaged in face-to-face social interactions in a laboratory setting. Relationship type and conversation context varied across studies, and high-frequency power was used to estimate RSA across resting baseline, anticipatory periods, and conversation tasks. Analyses indicated that anticipation of and engagement in dyadic social interactions were associated with an increase in RSA from a resting baseline. The mean estimated effect size for anticipation was r = 0.50, and the mean estimated effect size for conversation was r = 0.34. Associations were robust across relationship types, including strangers and romantic couples, conversation context, including topic and valence, and across speaking and listening roles. The present research provides consistent evidence for increased RSA in anticipation of and during in-person social interactions among adults, prompting the need for further investigation into potential underlying mechanisms.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70043"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11946932/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this multimodal assessment, the relationship between amygdala structure and function was investigated in mood and anxiety patients to determine their covariation and their relationship to trauma magnitude. Overall, amygdala volume and functional emotional reactivity were unrelated, with smaller volumes and reduced emotional reactivity each independently predicting trauma magnitude for women, and mediation analysis did not support a hypothesis that the relationship between reduced functional activity and trauma severity depends on amygdala volume. Structural and functional differences were instead separately related to different facets of trauma experience, highlighting the need for longitudinal and multimodal analyses to further elucidate the relationship between brain structure, function, and psychopathology.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70027"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11921970/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used the reading version of the flankers task in which participants had to classify foveal target words as either being a noun or an adjective. In Experiment 1, targets were flanked by either syntactically congruent or incongruent words (e.g., noun noun noun vs. adjective noun adjective), or were embedded in a sequence of words that was either grammatical or ungrammatical (e.g., adjective noun verb vs. verb noun adjective). Experiment 2 employed the same stimuli as the latter condition, with participants now tasked to judge the word sequence as being grammatically correct or not. Results showed a significant reduction in N400 amplitude for both the syntactically congruent and syntactically grammatical conditions in Experiment 1, and for syntactic grammaticality when making sentence judgments in Experiment 2. In the second experiment, a syntactically grammatical word sequence could be reliably decoded starting around 500 ms post-stimulus onset. These results indicate that skilled readers can extract and process syntactic information from multiple words in a short timeframe and that syntactic categories retrieved from individual words (i.e., parts-of-speech) are rapidly integrated into a sentence-level representation.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70019"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The location of spatial attention can be deployed without overt movements (covertly). Spatial dynamics of covert attention are exceptionally difficult to measure due to the hidden nature of covert attention. One way to implicitly index covert attention is via the pupillary light response (PLR), as the strength of PLR is modulated by where attention is allocated. However, this method has so far necessitated simplistic stimuli and targeted only one driver of covert attention per experiment. Here we report a novel pupillometric method that allows tracking multiple effects on covert attention with highly complex stimuli. Participants watched movie clips while either passively viewing or top-down shifting covert attention to targets on the left, right, or both sides of the visual field. Using a recent toolbox (Open-DPSM), we evaluated whether luminance changes in regions presumably receiving more attention contribute more strongly to the pupillary responses-and thereby reveal covert attention. Three established effects of covert attention on pupil responses were found: (1) a bottom-up effect suggesting more attention drawn to more dynamic regions, (2) a top-down effect suggesting more attention towards the instructed direction, and (3) an overall tendency to attend to the left side (i.e. pseudoneglect). Beyond the successful validation of our method, these drivers of covert attention did not modulate each other's effects, indicating independent contributions of bottom-up, top-down, and pseudoneglect to covert attention in stimuli as dynamic as the present. We further explain how to use Open-DPSM to track covert attention in a brief tutorial.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70036"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11920946/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143658286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ERPs were recorded while participants (N = 80) categorized the gender of faces expressing fear, anger, happiness, and no emotion. Participants then viewed each face again and rated them on arousal and valence using 1-9 Likert scales. For each participant, ratings of each unique face were linked back to corresponding ERP trials. ERPs were analyzed at all time points and electrodes using hierarchical mass univariate statistics. Three different ANOVA models were employed: the original emotion model, and models with valence or arousal ratings as trial-level regressors. Results from models with ratings highly overlapped with the original model, although they were more temporally restricted. The N170 component was the most impacted by arousal and valence ratings, with four out of six emotion contrasts revealing significant valence or arousal interactions. Emotion effects on the P2 component were mostly unrelated to ratings. On the EPN component, only two contrasts related to both arousal and valence ratings. Thus, ERP emotion effects are related to participants' perceived arousal and valence of the stimuli, although this association depends on the contrast analyzed. These findings, their limitations, and generalizability are discussed in reference to existing theories and literature.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70045"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11926668/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
