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}

This price ending effect is thought to be driven primarily by two factors: the left-digit effect which occurs when a small price drop changes the leftmost digit, and the image effect which stems from the symbolic association of a particular price ending with low prices or sales. Our study aimed to investigate the neural basis of these irrational effects on perceived cheapness using functional magnetic resonance imaging (fMRI). We used five price values in Yen (197, 198, 201, 202, 206; Japanese consumers tend to perceive prices ending in the number 8 as cheap) for fMRI experiment. Participants were asked to rate the price value of a product. The “left-digit effect” was observed based on the deactivation in brain regions associated with visuospatial processing including the left lingual gyrus and posterior middle temporal gyrus, and the right dorsal posterior precuneus and anterior precuneus. From these regions, the degree of deactivation in the right dorsal posterior precuneus was negatively correlated with the irrational perception of cheapness. Furthermore, this region showed negative functional connectivity with the dorsal striatal regions. No regions were found with “the image effect”. Our results suggested that a decrease in activity in the regions associated with visuospatial processing suggests that changes in the leftmost digits alter the level of visuospatial attention towards the price, leading to an underestimation of the payment amount. This reduced attention might activate the dorsal striatum driving unconscious purchasing.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"197 ","pages":"Article 109030"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143868577","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}

Specifically, we explored the relationship between depressive mood and heart rate (HR) patterns, hypothesizing that individuals prone to depressive mood might experience altered arousal during quarantine. We conducted similar analyses for blood pressure (BP) as well. Our findings revealed that, on average, HR increased during quarantine. Notably, individuals reporting higher depressive mood levels exhibited lower initial HR but experienced a sharper increase throughout the quarantine period. In contrast, no significant linear or quadratic changes were observed in systolic blood pressure (SBP). However, initial analyses did identify significant linear changes in diastolic blood pressure (DBP) and mean arterial pressure (MAP). These changes in DBP and MAP were not influenced by depressive mood and lost significance in sensitivity analyses that accounted for infection-related factors, health behaviors, and socio-demographic variables. Interestingly, HR trajectories remained significant in sensitivity analyses but lost significance when self-reported symptoms were included. Self-reported symptoms partially mediated the relationship between depressive mood and HR increases, suggesting that individuals with higher depressive tendencies also reported more infection-related symptoms, contributing to increased HR.

Uniquely, the present project focused on survivors of the Cambodian genocide and the subsequent two generations to determine whether brain alterations are observable approximately five decades after the traumatic event and in subsequent generations from the same society. Using portable electroencephalography (EEG), we used four experimental tasks—two targeting non-affective processing (i.e., sensory gating, oddball) and two targeting affective processing (i.e., emotion recognition, threat processing). Results indicated that although the rate of PTSD symptoms was similar across generations, the affective reaction to threat for the LPP and FMθ was primarily observed or intensified in the directly affected generation (i.e., G0), regardless of the presence of PTSD. We also observed that G0 exhibited reduced attenuation over standard tones in the oddball task for the N100 and a reduced sensory gating effect on the auditory P200. The present study underscores that affective and non-affective alterations might still be present decades after a trauma, but are not necessarily observable in subsequent generations.
