We conducted a multiverse analysis where 16 models were used to test a multiverse of relationships between ERP indices of inhibitory control and caloric or carbohydrate intake while controlling for age, biological sex, weight, and body mass index (BMI).

Food intake was recorded using the online Automated Self-Administered 24-hour Dietary Assessment Tool. Results generally found no significant relationship between ERP measures and calorie or carbohydrate intake. Biological males, heavier individuals, and those with higher BMIs tended to consume more food. Inhibitory control, as measured by the N2 and P3 ERP components during a high-calorie go/no-go task, does not consistently relate to food intake in the current multiverse analysis.

Therefore, PAC is theoretically well-suited for ADHD research. However, the differences in PAC characteristics among children with ADHD subtypes have not yet been thoroughly investigated. This study recorded resting-state electroencephalographic (rsEEG) from 19 healthy controls (HCs), 33 children with predominantly inattentive type (ADHD-I), and 39 with combined type (ADHD-C). We examined intra- and inter-channel PAC differences across different spatial scales and further analyzed PAC-based brain network properties. The results showed that both ADHD subtypes had stronger α-γ PAC than HCs, with ADHD-C exceeding ADHD-I. ADHD-I showed mainly intrahemispheric changes, while ADHD-C involved the left hemisphere and occipital regions. In the α-β band, PAC was significantly higher in ADHD-C than in ADHD-I, mostly in the left brain. ADHD-I also showed increased inter-channel δ-β PAC compared to HCs, with widespread distribution. These findings suggest the presence of compensatory hyperactivation mechanisms in ADHD, particularly in the ADHD-C subtype. Further brain network analysis supported the “delayed maturation theory” of ADHD and indicated that ADHD-C may represent a shift from a typical small-world network architecture to a more regular network organization. Finally, the (Support Vector Machine) SVM classification results further validated the discriminative power of these features in differentiating HCs from ADHD subtypes. Overall, these findings indicate significant differences in PAC strength and brain network topology among ADHD subtypes, suggesting their potential as biomarkers for distinguishing HCs from ADHD subtypes.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"215 ","pages":"Article 113222"},"PeriodicalIF":2.5,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144676631","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}

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.
