To address this gap, our study investigated the relationship between grit and physiological responses, focusing on resting-state heart rate variability (HRV)-a physiological marker of well-being and adaptability. Additionally, we examined whether this relationship was unique to grit and not explained by other related psychological constructs (i.e., conscientiousness and self-control).

Dual-task studies have shown that walking, in particular, may impact performance during cognitive tasks. However, the existing literature shows inconsistent results; changes in performance have been reported to be sometimes ameliorative, sometimes neutral, and at other times detrimental to both cognitive and motor functions. The present study aims to investigate the effects of walking on the motor and cognitive brain processes that underlie task anticipation during a visual discrimination cognitive task. For this purpose, event-related potentials were recorded under two conditions: static standing and walking on the treadmill while participants executed a cognitive task. The presence of optic flow was also controlled to assess its effect on realistic walking. The results show that walking enhanced both motor and cognitive preparation processes, improving response speed and accuracy. This effect may suggest that walking during the execution of a visuomotor cognitive task may not interfere with task preparation and even result in increased cortical activation in prefrontal and premotor areas, thereby improving cognitive performance. Furthermore, the presence of optic flow was found to enhance motor preparation and reduce response time, supporting the efficacy of more realistic walking conditions. However, the presence of a flow field also reduced cognitive preparation and accuracy, likely due to the increased cognitive load associated with concurrent visual information. These findings support the \"multiple resources theory,\" which posits that during dual tasks that do not interfere with each other, the brain can optimize cortical integration and enhance both cognitive and motor resources.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70063"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144031087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted two independent experiments (N<sub>1</sub> = 37, N<sub>2</sub> = 34) with a learning phase and a recall phase 7 days later.

As an out-of-sample generalization test, experiment 2 confirmed the result for HPR during learning (g = 0.78) and recall (g = 0.55), as well as for PSR during recall (g = 0.41).

A direct and conceptual replication of Meyer et al. (2013, Psychophysiology) was conducted in 182 participants to assess the internal consistency of ERN from flanker, go/no-go, and Stroop tasks as a function of increasing trials. Analyses were extended to include error positivity (Pe) and difference scores (ΔERN, ΔPe), and generalizability theory and multilevel models were used to statistically compare internal consistency across tasks. Overall, data supported the internal consistency of results across three tasks in a healthy undergraduate sample, with values ranging from 0.70 to 0.97 when examining all data. However, estimates were in part outside the confidence intervals of the original study, and ERN scores showed lower internal consistency than previously reported for a flanker task and higher internal consistency than previously reported for a Stroop task. Pe score internal consistency was similar across tasks when examining the average number of error trials. These findings underscore the importance of examining reliability in each study rather than relying on universal trial cutoffs. Overall, a flanker task may be better suited for studies of ERN due to the higher internal consistency of ERN scores when including data from all error trials. However, exclusively using a single task is discouraged because understanding the functional significance of ERN and Pe requires considering task-specific nuances and the varying contributions of cognitive processes, such as cognitive control or response inhibition.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 4","pages":"e70042"},"PeriodicalIF":2.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143981148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been recently proposed that theta band oscillations (~4-8 Hz) in the frontal midline regions are a key mechanism of endogenous selective attention.

Time-frequency analyses were used to quantify phase- (evoked) and non-phase-locked (induced) fronto-central theta activity during preparatory attentional states. In a sample of 20 young adult participants, we found that those who relied on the cues to selectively attend to the sensory modality of the discrimination task performed more efficiently (i.e., faster and with greater accuracy) and presented greater non-phase-locked fronto-central theta power 200-400 ms post-cue onset. Moreover, greater non-phase-locked theta oscillations were associated with better behavioral performance. Secondary analyses on alpha oscillations revealed concomitant brain activity to theta with a pronounced decrease in alpha power in fronto-central regions, without significant effect on task performance.

As an index of fear learning, FPS was measured using the magnitude of eyeblink startle reflex to a sound probe. Twin model estimates indicated that both pre-acquisition startle (startle probe responses to stimuli prior to conditioning) and FPS (startle probe responses after conditioning during acquisition and generalization) exhibited modest to moderate heritability (26%-43%), aligning with previous studies on FPS. We also observed that the genetic influences on FPS were highly correlated with pre-acquisition startle, indicating minimal genetic innovation on FPS.
