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.

Whether or not self-face and self-voice are processed more accurately than others' remains inconclusive. Most previous studies asked participants to judge the presented stimulus as their own others', compared response accuracy discuss self-advantage. However, it is possible that responded correctly in "other" trials by identifying but rather rejecting "self." The present study employed an identity-irrelevant discrimination task, which detected odd among three sequentially stimuli. We measured thresholds for self, friend, stranger conditions. In Experiment 1 (face), self friends' faces were lower those strangers' faces. This suggests may be perceived special unique, facial representation become accurate due increased familiarity through repetitive exposure. Whereas, 2 (voice), did differ between conditions, suggesting sensitivity changes same regardless of identity. Overall, we found no evidence self-advantage identification accuracy, observed a familiarity-advantage face processing null difference voice processing.

Self-cues such as one's own name or face attract attention, reflecting a bias for stimuli connected to self be prioritized in cognition. Recent evidence suggests that even external voices can elicit this self-prioritization effect; voice-label matching task, assigned the Self-identity label 'you' elicited faster responses than those 'friend' 'stranger' (Payne et al., Br. J. Psychology, 112, 585-610). However, it is not clear whether Self are over participants' voices. We explore issue two experiments. In Exp 1 (N = 35), task comprising three confirmed reaction time and accuracy improved when an voice cue rather Friend Stranger. 2 90), one of cues was replaced with recording participant's voice. Reaction showed consistent advantage own-voice, identity. These findings show effects if associated Self, but they above individuals' This has implications production technology, suggesting own-voice imitation may beneficial.

Abstract Recently, it has been proposed that self-relevance of a stimulus enhances executive control and reduces the impact distractors on current task performance. The present study aimed to test whether binding between distractor response is influenced by self-relevance, too. We assumed targets’ should increase processes therefore reduce influence In distractor–response-binding (DRB) task, which measures strength stimuli responses, we varied target relevance so participants responded targets either were or not self-relevant. Our design made possible measure DRB effects for both conditions separately. diminished if self-relevant compared when they not. These results expand our understanding cognitive purely perceptual (Sui & Humphreys, 2012, Journal Experimental Psychology: Human Perception Performance, 38 [5], 1105–1117), but also found in higher-order such as control. Moreover, whereas different paradigms advantages are 2015a, Trends Cognitive Sciences , 19 [12], 719–728; Humphreys Sui, 2016, Neuroscience, 7 [1/4], 5–17), this identifies an important boundary condition, distractor–response reduced self-relevance.

As a social species, humans live in complexly bounded groups. In order to navigate these networks, rely on set of social-cognitive processes, including working memory. Here, we designed novel network memory task study for versus non-social information across 241 participants (18-65 years) tightly controlled, preregistered study. We show that demonstrate advantage social, relative non-social, information. also observed self-relevant positivity bias, but an 'other' negativity bias. These findings are interpreted the context evolutionary need belong one's group, identify risks safety and appropriately track status within complex relationships.

The preferential processing of self-related information is thought to be driven by its high level familiarity. However, some behavioral studies have shown that people may exhibit a preference for initially unfamiliar stimuli been associated with themselves arbitrarily. One the key questions needs addressed concerns role early attention in prioritization newly acquired self. Another question whether both highly familiar as well new referring subjectively significant person (i.e. close-other) benefits from attentional processing. We aimed tackle investigating neural mechanisms involved extremely stimuli, like one's own face or close-other, (abstract shapes) were linked each person. used dot-probe paradigm allowed us investigate stages prioritization.
