It has been recently proposed that theta band oscillations (~4-8 Hz) in the frontal midline regions are a key mechanism of endogenous selective attention. The current electroencephalography study investigated theta oscillatory dynamics using an inter-sensory cueing paradigm in which a symbolic cue indicated, on a trial-by-trial basis, the modality (visual or auditory) of the upcoming discrimination task. Time-frequency analyses were used to quantify phase- (evoked) and non-phase-locked (induced) fronto-central theta activity during preparatory attentional states. In a sample of 20 young adult participants, we found that those who relied on the cues to selectively attend to the sensory modality of the discrimination task performed more efficiently (i.e., faster and with greater accuracy) and presented greater non-phase-locked fronto-central theta power 200-400 ms post-cue onset. Moreover, greater non-phase-locked theta oscillations were associated with better behavioral performance. Secondary analyses on alpha oscillations revealed concomitant brain activity to theta with a pronounced decrease in alpha power in fronto-central regions, without significant effect on task performance. These findings suggest that increased non-phase-locked fronto-central theta oscillations are a neuronal correlate of preparatory attentional control and that the interplay of theta-alpha rhythms differentially contributes to attentional and perceptual aspects.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70055"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11980533/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143812167","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}

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.</p>","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.

IBI changes from cycle to cycle. Periods with longer IBI are associated with higher sensitivity to external sensory stimuli (exteroception). Warning cues induce a state of attentive anticipation characterized by an increase in IBI (anticipatory cardiac deceleration) and faster reaction times. Aging reduces the increase in IBI induced by warning cues and response speed. However, it is unclear which mechanism, if any, connects IBI with reaction time. The heartbeat-evoked potential (HEP) is a cortical response evoked by the heartbeat, modulated by attention and associated with sensitivity to external sensory stimuli. HEP might be affected by IBI and mediate the association between cardiac output and cortical processing. We investigated if the HEP was affected by warning cues as well as spontaneous fluctuations in IBI. To explore the impact of age-related changes in cardiac responses, we included young and older people (N = 33/29; 26/23 women; mean age 23/61 years). We analyzed the electroencephalograms and electrocardiograms simultaneously acquired during auditory cued simple reaction time and go/no-go tasks. The warning cue did not induce significant changes in the HEP. Yet, fluctuations in IBI (not locked with the warning cue) affected the HEP, and HEP amplitude was associated with average reaction time in the older group. However, on a trial-by-trial basis, reaction time was independent from IBI fluctuations. In conclusion, we found no evidence that the HEP mediates the effect of attention orienting on reaction time.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70057"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144041869","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}

In addition, higher-order sensory areas might be involved in bridging a temporal gap between stimulus and feedback by reactivating the representation of the feedback-predicting stimulus during feedback processing. We hypothesized that the feedback-locked N170, an occipito-temporal event-related potential (ERP) component linked to higher-order visual processing, is more pronounced when delayed feedback is provided for choices between visual compared to auditory stimuli. 35 subjects completed a probabilistic feedback learning task with immediate (1 s) and delayed (7 s) monetary feedback for choices between visual or auditory stimuli. Participants successfully learned to choose the more rewarding stimuli irrespective of stimulus modality. For the N170 amplitude over the right hemisphere, we found an interaction between feedback timing and the modality of the chosen stimulus. Only for delayed feedback, the N170 was more pronounced for choices between visual than auditory stimuli. Moreover, in this condition, the N170 amplitude particularly reflected the reward prediction error (PE), with larger amplitudes for positive PEs and lower amplitudes for negative PEs. This suggests that the N170 reflects feedback-locked reactivations in higher-order visual areas mediated by the reward PE. While these effects need to be studied further, we discuss the N170 as a counterpart to the feedback-related negativity (FRN) regarding interacting influences of feedback valence, feedback timing, and PE.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70050"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11998638/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144042568","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}
