Additionally, staircase training increased the frontal P2 amplitude; accordingly, moderate constant stimulus training reduced the frontal P2 amplitude and increased the frontal N2 amplitude. Importantly, the change in frontal P2 amplitude was correlated with improved performance, indicating the involvement of cortices responsible for higher-order cognitive processes in VPL. Additionally, the difference in frontal P2 amplitude changes suggests the modulation of training methods (adaptive and consistent) on the role of attention in VPL.

This paper investigated the electroencephalography features of binocular color fusion and binocular color rivalry when watching stereoscopic three-dimensional (3D) displays. EEG experiments were conducted on a conventional 3D display platform. Eight subjects were involved to analyze differences in the event-related potential (ERP) and power spectrum when the brain perceived binocular color fusion and binocular color rivalry. Results show that: 1) the latencies of ERP components N1 and P2 of binocular color fusion were shorter than that of binocular color rivalry, 2) the amplitudes of the ERP components P2 and P3 of binocular color fusion were greater than that that of color rivalry, and 3) the left hemisphere was dominant for binocular color rivalry while the right hemisphere was greater involved in binocular color fusion. These results indicate that during the initial and mid-term cognitive processing, the brain response to binocular color fusion is faster than binocular color rivalry. Both binocular color fusion and rivalry involve visual post-processing, but binocular color fusion requires a greater allocation of neural resources. Power spectrum analysis revealed the cerebral lateralization in binocular color fusion and rivalry, it suggested that the way the brain processes this binocular input can have effects on its function.</div></div>","PeriodicalId":55331,"journal":{"name":"Brain and Cognition","volume":"184 ","pages":"Article 106268"},"PeriodicalIF":2.2,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142984781","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 current study randomly assigned participants to high (low) SES groups and asked them to complete the environmental donation task in the (non) observable contexts while the electroencephalogram was recorded. Behaviorally, this study revealed that the presence of others promoted environmental donations in the low-cost condition and the average donations and acceptance rates were influenced by costliness. The ERP results indicated that high-SES individuals exhibited more negative N2 in the observable condition than in the non-observable condition. At the later stage, social observation modulated the neural activity evoked by donation decision making, with high-SES individuals showing larger P3 and late positive potentials (LPP) in the observable (vs. non-observable) condition.

In this study, we investigated the neural basis of both communal enjoyment and individual anticipatory responses during short video viewing. Using functional MRI, we measured brain activity in participants as they watched 90 short videos and provided ratings of their reward expectations and experienced pleasure. By integrating intersubject correlation (ISC) and individual-specific analyses, we identified shared and unique neural activity patterns. Our findings reveal that synchronized activity within the default mode network (DMN) and reward-related regions underlies shared experiences of collective pleasure.

The ERP differential measuring how much attention was allocated to the targets vs. distractors increased significantly with SES, independently of age. To explain these findings, we integrate the ear to the ground hypothesis and the socioenvironmental epigenetic stress approach. According to the ear to the ground hypothesis, frequent and prolonged environmental uncertainty and hazard induce low-SES children to learn adaptive over-vigilance, attending disproportionately to stimuli that are currently irrelevant but may quickly become relevant and thus require an immediate survival response. Socioenvironmental epigenetic stress refers to the bidirectional interaction between a stress-inducing environment and the impact and expression of transgenerational gene selections in low-SES contexts. Because low-SES individuals are historically under and misrepresented in research, the proposed framework contributes to increase our understanding of how socioeconomic and environmental conditions may affect neurocognitive development.
