Abstract Self-related information is crucial in our daily lives, which has led to the proposal that there a specific brain mechanism for processing it. Neuroimaging studies have consistently demonstrated default mode network (DMN) strongly associated with representation and of self-related information. However, precise relationship between DMN activity information, particularly terms neural oscillations, remains largely unknown. We electrically stimulated superior temporal fusiform areas, using stereo-electroencephalography investigate oscillations elicited auditory hallucinations. Twenty-two instances hallucinations were recorded categorized into other-related conditions. Comparing oscillatory power changes within hallucinations, we discovered are significantly stronger positive both alpha gamma bands compared To ensure validity findings, conducted controlled analyses factors familiarity clarity, revealed observed effects remain independent these factors. These results underscore significance functional role during shed light on perception activity.

Abstract From attentional prioritization to enhanced memory, self‐cues trigger a variety of effects within human cognition. Recent work suggests that self‐reference may also enhance working possibly via prioritization. However, there is no direct evidence memory capacity, or such boosts covary with individuals' function. Here, we provide the first capacity for self‐referential cues, independent processing. We adapted verbal complex span create ‘Self’ condition (featuring participant's own name), ‘Other’ non‐self‐name), and Control (with in 7–9‐year‐old children (Exp.1, N = 71) adults (Exp.2, 52).

Abstract Our everyday perceptual experiences are grounded in the integration of information within and across our senses. Due to this direct behavioural relevance, cross‐modal retains a certain degree contextual flexibility, even social relevance. However, how relevance modulates remains unclear.

Efficiently processing self-related information is critical for cognition, yet the earliest mechanisms enabling this self-prioritization remain unclear. By combining a temporal order judgement task with computational modelling based on Theory of Visual Attention (TVA), we show how mere, arbitrary associations self can fundamentally alter attentional selection sensory into short-term memory/awareness, by enhancing weights and capacity devoted to encoding socially loaded information. This in occurs automatically at early perceptual stages but reduces when active social decoding required. Importantly, benefits obtained from via self-relatedness physical salience were additive, suggesting that captured attention separate mechanisms. Furthermore, intra-individual correlations revealed an ‘obligatory’ effect, whereby overpowered contribution guiding selection. Together, our findings provide evidence influence during earlier, automatic section gateway perception, distinct later post-attentive stages.

A redundancy gain occurs when perceptually identical stimuli are presented together, resulting in quicker categorization of these paired than lone stimuli. Similar effects have been reported for within the same conceptual category, particularly if category is self-related. We recruited 528 individuals across three related studies to investigate whether, during perceptual and redundancy, such self-bias on foreground modulated by natural versus urban backgrounds. Here, we highlight our observations pertaining In first experiment, response options were randomised per trial. Results showed reaction time gains stimuli, but this advantage was not self/other categorization. However, slower times observed conceptually-related stimulus pairs influenced The second experiment replicated methods earlier comparable results Experiment 1: a unmodulated categorization, yet no gain/cost third categories substituted with arbitrary A/B categories: Once more, there gain. Notably, categorisation produced equivalent categorisation. Overall, findings challenge previous research facilitated early processing suggest that self-relatedness may exert unique effect beyond attentional preferences Our study motivates further understand effects.

Prioritizing immediate self (me, now) over distant (other, future) information is an essential social cognition for effectively guiding actions at hand. Building upon recent research on the nuanced nature of prioritization effects, we sought to explore whether such biases could be modulated by external rewards, thereby enhancing task saliency. Our results (N = 161) demonstrated that while effects response speed remained robust against performance contingent accuracy were susceptible modulation. Specifically, rewards amplified both self- (vs other) relevant and information. These findings suggest a potential overlap in processing mechanisms between temporal domains. study contributes novel evidence understanding highlighting their malleability factors. Future investigations should additional factors influencing these biases, shedding light functional roles prioritization.
