Such tasks require one hand to act as a manipulator and the other hand as a stabiliser, and choosing the hand to perform each role is termed hand role selection. The dominant and non-dominant hand are usually spontaneously assigned as the manipulator and stabiliser, respectively. Both handedness and age are known to affect coordination during bimanual tasks, but their influence on spontaneous hand role selection across a range of tasks is unknown. This study investigated the effects of handedness and age on spontaneous hand role selection during routine bimanual tasks. Fifty healthy adults (mean age = 53, range 19 - 85 years) performed seven bimanual tasks with five repeats each. Participants were naïve to the study's purpose to avoid any influence on their hand role selection. Handedness was determined using the 10-item Edinburgh Handedness Inventory. Hand role selection in each trial was noted to calculate a Preference score out of 35 for each participant. Overall, participants had a strong preference to consistently use their dominant hand as a manipulator across all tasks. Preference to use the dominant hand as a manipulator was task-dependent and correlated positively with handedness, but it did not correlate with age. These results show the degree of handedness, but not age, affects consistency of hand role selection across a range of bimanual task, and that preference to use the dominant hand as a manipulator varies between tasks.","PeriodicalId":12268,"journal":{"name":"Experimental Brain Research","volume":"244 6","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13121369/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While altered neural responses are documented in overweight and obese individuals, less is known about the full BMI spectrum, particularly in underweight adults. This study examined behavioral and neural correlates of reactive inhibition across four BMI groups (underweight, normal-weight, overweight, obese) in 87 young adults (Mage = 22.82, SD = 4.18). Participants performed a Go/NoGo task in neutral and food-related contexts while EEG was recorded. Analyses focused on N2d and P3d components. No behavioral differences emerged between groups. However, P3d amplitudes (but not N2d) showed significant BMI-related modulation (F(3,83) = 2.76, p = 0.047), driven by larger amplitudes in overweight participants compared to underweight and normal-weight individuals. Curve estimation analysis revealed a significant quadratic relationship between BMI and P3d amplitude (R2 = 0.073, p = 0.041), which provided a superior fit compared to the linear model (R2 = 0.061, p = 0.021). Elevated BMI is associated with increased neural recruitment during inhibition, suggesting a compensatory mechanism to maintain behavioral performance. The quadratic pattern suggests that this compensatory efficiency reaches a plateau or begins to stabilize beyond the overweight range. These findings highlight the importance of indexing neural inhibitory markers to identify cognitive vulnerabilities in weight regulation.","PeriodicalId":12268,"journal":{"name":"Experimental Brain Research","volume":"244 5","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147697972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
