It has been shown that a salient arousing image in the background of a cognitive task consumes processing resources from the superimposed task, producing a deleterious effect on performance. On the other hand, experiments designed to change the focus of attention during the processing of emotional stimuli have shown a reduction of the emotional response, indicating an attentional competition between significant stimuli simultaneously presented. This research aimed to describe the competition between the performance on a cognitive task presented in a reduced space of the image (1.2 %) and the processing of emotional images displayed at the background using EEG and Eye Tracking. Results showed that the superimposition of the task had an early attractor effect, evidenced by an above-chance decoding accuracy (about 180 ms since the image onset) and an enhancement in the N1 component. This engagement in the task reduced the processing of the images as evidenced by a decrease in the LPP amplitudes, an enhancement in the a-ERD and a greater dwell-time over the task. Additional analysis showed that the unpleasant pictures were visually explored and emotionally processed after participants responded to the task. In conclusion, the present study supports the competition model of selective attention, highlighting the dominance of top-down control in shaping perceptual and cognitive processing.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"214 ","pages":"Article 113221"},"PeriodicalIF":2.5,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144631818","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}

The fatigue group completed a difficult task, while the control group watched a documentary, before both groups performed the same difficult subsequent task. Subjective fatigue, performance, and cardiovascular responses were assessed. Participants in the fatigue group reported significantly higher levels of subjective fatigue and lower effort intensity during the subsequent task compared to the control group, as evidenced by reduced PEP and HR reactivity. Despite these differences, performance on the subsequent task did not differ between groups. These findings suggest that a prior difficult task can increase the perceived difficulty of subsequent tasks. When the subsequent task is also difficult, the effort required may be viewed as no longer worthwhile, leading to reduced effort investment.

To address this issue, participants from two large independent samples (<em>N</em>₁ = 479, <em>N</em>₂ = 445) were recruited to undergo resting-state functional magnetic resonance imaging (fMRI) and complete questionnaires measuring PFTP and procrastination.

After giving consent, the participants were administered a semi-structured interview that included the Mini International Neuropsychiatric Interview (MINI) to determine cannabis use disorder (CUD) status. If a participant met the criteria for CUD, they were instructed to wear a Garmin smartwatch for three consecutive days. The Garmin smartwatch collected interbeat intervals via photoplethysmographic measurement. Participants were also instructed to complete a survey each time they smoked cannabis, a survey that asked for the start and stop times for each cannabis smoking session. Employing mixed ANOVA and Multilevel models, results suggest a significant difference in HRV levels before and after self-reported cannabis smoking. Specifically, both time and frequency domain HRV metrics are significantly lower than levels prior to smoking cannabis. Further, we see a significant increase in average heart rate from before to after cannabis smoking.

This study utilized FPVS to investigate neural responses to facial expressions in individuals with elevated anxiety-related characteristics (e.g., prior diagnosis or elevated symptom scores) and those without. EEG responses were recorded while participants viewed sequences of neutral faces interspersed with emotional oddball expressions (angry, fearful, happy, and sad). Results revealed robust neural discrimination responses to all facial expressions. Participants with anxiety-related characteristics showed significantly greater summed baseline-corrected amplitudes (BCA) at occipital electrodes in response to angry and sad oddball faces compared to the low-anxiety group. This was accompanied by reduced top-down interactions. Although, dimensional anxiety scores were generally low, suggesting results may reflect residual or trait-level differences rather than acute symptomatology, these findings provide preliminary evidence that FPVS may be sensitive to enduring differences in emotion processing associated with anxiety vulnerability.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"214 ","pages":"Article 113212"},"PeriodicalIF":2.5,"publicationDate":"2025-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144571789","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}

Twenty-seven nonimpaired (13 men, 20–31 years) and 25 dyslexic (11 men, 20–32 years) readers were presented with sentences that included four possible endings: a congruent ending in which the last word was semantically related to the sentence, an incongruent ending with no semantic relationship, a homophone which was based on a congruent word, and an orthographically similar word to a congruent word. The participants were asked to decide if the sentence-final word was semantically related to the sentence. Response accuracy, reaction times, and both amplitude and peak latency of the N400 were investigated. The N400 component has been reported as a brain measure that reflects the integration of phonological and orthographic processes into meaning during word reading.
