Self-report measures of self-control reflect higher-level cognitive appraisals of behavioral control and lower-level innate temperamental traits associated with reactive processes. However, few studies have examined the extent to which different aspects of self-control relate to reactive processes. Using a large sample (<em>n</em> = 246), we investigated whether individual differences in six self-control trait measures were predictive of low-level processing indexed by the mismatch negativity (MMN) elicited from a passive auditory oddball task. Larger MMNs are associated with greater prediction error when the input stimulus conflicts with expectation. Self-control traits were measured by effortful control, perfectionism, impulsiveness, procrastination, perceived stress, and anxiety scales. We assumed personality traits develop around innate differences in reaction to environmental changes, resulting in differential adult expressions of self-control reflected in the six traits. All but perfectionism and perceived stress correlated with MMN amplitudes: Greater self-control associated with smaller MMNs; stronger negative traits associated with larger MMNs. When the correlated measures were entered into a backwards multiple regression on MMN amplitudes, procrastination and anxiety remained in the model as significant, relatively independent contributors. Procrastination may reflect a top-down modulation of underlying reactivity. Trait anxiety may reflect a basic temperament of greater reactivity to environmental change. Individuals with strong innate reactivity and weaker top-down processes may be hypervigilant to deviations from expectation, producing larger prediction errors and MMNs. Self-control failures may reflect reduced top-down control, when the balance in cortical activity favors reactive systems over the prefrontal cortex.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"214 ","pages":"Article 113202"},"PeriodicalIF":2.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144470200","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 present study aimed to explore how the experience of searching expectation-incongruent targets affects trial-by-trial visual search through expectation updating and cognitive control processing. Here, we analyzed event-related potentials (ERPs) related to behavioral results during the search tasks. The results revealed distinct cognitive control mechanisms under similar behavioral results in the context of different type of associations.

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 a laboratory-controlled setting, we examined individual differences in alertness alteration during overnight wakefulness—a more common form of sleep loss in real life—and explored the associated resting-state EEG spectral signatures. Forty-five participants remained awake from 22:00 to 06:00, during which they completed subjective ratings, a 10-min psychomotor vigilance task (PVT), and resting-state EEG recordings every 2 h. Based on the changes in overnight PVT performance, participants were grouped as vulnerable (<em>N</em> = 20) or resilient (N = 20). Vulnerable individuals exhibited larger variations in frontal theta power, whereas resilient individuals demonstrated relatively stable resting-state EEG activities during prolonged wakefulness. Furthermore, higher theta power in the parietal region was observed in vulnerable people before prolonged wakefulness, which might be a predictor of vulnerability to prolonged wakefulness. Future studies with larger and independent datasets are needed to validate these spectral indicators and clarify underlying mechanisms.</div></div>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":"214 ","pages":"Article 112602"},"PeriodicalIF":2.5,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144241729","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. The behavioral results revealed that the dyslexic readers were less accurate overall compared to the nonimpaired readers. In addition, the dyslexic readers had longer reaction times for the phonological, orthographic, and incongruent conditions compared to the nonimpaired readers. The N400 results showed that the dyslexic readers produced larger amplitude compared to the nonimpaired readers for the congruent (<em>p</em> = 0.021) and orthographic (<em>p</em> = 0.041) conditions. Moreover, the dyslexic readers had longer latency than the nonimpaired readers for the congruent (<em>p</em> = 0.012), orthographic (<em>p</em> = 0.015), and incongruent (<em>p</em> = 0.011) conditions.

To address the significance of HRV and socioeconomic status in adolescents in the Majority world, in the present study, we assessed resting-state HRV, socioeconomic status, and depression in adolescents from Nigeria. We also assessed their mood and perceived stress for four consecutive days. The results indicated that socioeconomic backgrounds were not significantly associated with self-report measures on mood, perceived stress, and depression.

During their hospital stay, they completed a test-retest event-related potentials (ERPs) Go-Nogo task, using neutral versus alcohol-related contexts. The first session (T0) took place approximately 4–7 days after admission, once withdrawal symptoms had subsided, and the second (T1) occurred just before discharge, around 15 days later.

The main result of this study was that an increase in the Nogo P3 component appeared to act as a protective factor against early relapse in detoxified AUD patients.
