Participants were initially asked to remember the task-relevant feature of one (low load), two (medium load), or four (high load) items, while ignoring their task-irrelevant features. Participants were required to make responses to the target in the subsequent search task, while being presented with distractors that include either task-irrelevant or task-relevant features. No features matched with studied items in the neutral trials. The items' color was manipulated as a task-relevant feature in Experiment 1, while their shape was designated as a task-irrelevant feature. Conversely, the items' shape was manipulated as a task-relevant feature in Experiment 2, and their color was designated as task-irrelevant. The event-related potentials evoked by the visual search task were also examined. The results showed that, in both experiments, 1) The response time showed no differences between task-irrelevant trials and neutral trials among different load conditions, suggesting that the task-irrelevant distractors may not slow down the target searching. 2) The magnitude of the target-elicited N2pc was similar between the neutral and the task-irrelevant trials among different load conditions, indicating that the task-irrelevant distractor received no attention and had no effect on the target processing. The results indicated that the task-irrelevant features were suppressed or completely disregarded.</p>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":" ","pages":"109049"},"PeriodicalIF":2.7,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144086786","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 2 studies using standardized images and sounds, and varied 30-s audio clips, in trials with higher self-reported disgust and sadness there was a consistent relationship with pupil dilation. Disgust was most often the strongest predictor of pupil dilation. This effect emerged ∼2 s after stimulus onset and remained present throughout stimulus presentation. Happiness had a weaker effect on pupil dilation and fear was associated with a late pupillary response. Anger was associated with pupil constriction, but only in Study 2. The present approach finds the most consistent relationship between pupil dilation and self-rated disgust and sadness, compared to other negative emotions.

The relationship between tactile deterioration and cognitive decline may be attributed to neurodegenerative aging processes involving neuronal plasticity and synaptic density alterations, affecting both sensory and cognitive systems. Consequently, loss of tactile information could serve as an early indicator of cognitive decline, enabling timely interventions to delay the onset of dementia.

This misalignment leads to sleep deprivation and has been identified as a risk factor for poor academic performance. Understanding the relationship between social jetlag and inhibitory control is crucial, since academic achievement relies on inhibitory control, the ability to maintain and pursue a goal while inhibiting goal-irrelevant information. In this event-related potential study, we examined the impact of social jetlag on inhibitory control across three domains of distraction: Self-generated information, perceived environment, and habits. Each distraction domain was assessed using a well-established cognitive task: n-back, flanker, and global-local task, respectively. We assessed the relationship between social jetlag, task performance, and neural activity in young male adults who self-identified as evening chronotypes. Results provide evidence for an association between social jetlag and early conflict monitoring (N2 component), but not later inhibition monitoring (P3 component). Specifically, increased N2 amplitudes at the non-optimal time of day were found in the absence of behavioral differences. Future studies need to confirm whether this finding reflects compensatory neural mechanisms to maintain stable performance despite increased sleep pressure. Highlighting the multifaceted nature of inhibitory control, the relationship between social jetlag and inhibitory control varied by distraction domain, with associations in the n-back task and the congruent global-local task condition, but not the flanker task.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"198 ","pages":"Article 109042"},"PeriodicalIF":2.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143917619","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}

However, whether excessive consumption of visual sexual stimuli fits classic models of addiction and involves reinforcement-based learning remains controversial. To address this question, the present study focused on the interplay of individual differences in trait sexual desire (specifically, the drive to engage in solitary sexuality) with stimulus modality in appetitive Pavlovian conditioning. 62 heterosexual participants (final sample, 36 women) underwent two sessions of differential conditioning, spaced one week apart. During one learning session, neutral cues were reinforced (50 %) by presentation of visual sexual stimuli, while auditory sexual stimuli served as unconditioned stimuli during the other session. Indexing both sexual arousal and appetitive learning, pupil dilation (as well as startle modulation) was used to track the acquisition of conditioned responses. Results revealed that solitary sexuality was associated with blunted differential pupillary responses to cues predicting visual (yet not auditory) sexual stimuli and less sensitization across trials, presumably reflecting reduced anticipatory arousal (consistent with self-report findings) and/or altered processing of uncertainty. At the same time, both enhanced startle habituation and valence ratings suggest that the preference for erotica was unaffected in individuals high in solitary sexuality. Fitted computational models provide additional evidence for a link to divergent learning trajectories. Taken together, our findings underscore the special nature of visual sexual stimuli (compared to auditory sexual stimuli) and support the view that excessive consumption may reflect a dispositional reward deficiency that drives individuals to seek out more intense stimulation.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"198 ","pages":"Article 109046"},"PeriodicalIF":2.7,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143937789","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}

Individual differences in brain, heart, and brain-heart responses to threat may provide biological markers for threat-related personality traits and psychopathology. However, to serve as psychophysiological markers the observed phenomena need to be replicable and individual differences in these phenomena must be reliably assessed and be temporally stable. To address this issue, N = 60 participants of our previous study completed the same auditory oddball paradigm with threat of shock vs. safe contexts 6 months after the initial study. With regard to replicability, all experimental effects that were observed during the first time were also significant 6-months later. With regard to reliability, amplitudes of original ERP waveforms, evoked HP changes and one CECT component showed substantial split-half and test-retest correlations. Moreover, difference scores (threat minus safe) for the P2 and N1 also showed substantial split-half (.55 <r <.72) and test-retest correlations (.41 <r <.67) indicating that individual differences in brain responses to threat vs. safety can be reliably assessed and show moderate stability.
