“…Notably, we also observed a very similar pattern of results at a fronto-central cluster of electrodes (see Fig 7D). Although these electrodes were selected based on a task-independent localizer procedure, aiming at identifying electrodes that were maximally sensitive to auditory stimuli, due to methodological constraints and anatomical characteristics of auditory cortex (Clements et al, 2023), it is unlikely that the observed power modulations reflect auditory oscillations. However, consistent with our results, modulations of fronto-central alpha power have been previously observed in a cross-modal matching paradigm.…”

Although real-life events are multisensory, how audio-visual objects are stored in working memory is an open question. At a perceptual level, evidence shows that both top-down and bottom-up attentional processes can play a role in multisensory interactions. To understand how attention and multisensory processes interact in working memory, we designed an audio-visual delayed match-to-sample task in which participants were presented with one or two audio-visual memory items, followed by an audio-visual probe. In three different blocks, participants were instructed to either (a) attend to the auditory features, (b) attend to the visual features, or (c) attend to both auditory and visual features. Participants were instructed to indicate whether the task-relevant features of the probe matched one of the task-relevant feature(s) or objects in working memory. Behavioral results showed interference from task-irrelevant features, suggesting bottom-up integration of audio-visual features and their automatic encoding into working memory, irrespective of their task relevance. Yet, ERP analyses revealed no evidence for active maintenance of these task-irrelevant features, while they clearly taxed greater attentional resources during recall. Notably, alpha oscillatory activity revealed that linking information between auditory and visual modalities required more attentional demands at retrieval. Overall, these results offer critical insights into how and at which processing stage multisensory interactions occur in working memory.

“…In this study, in the early stage of competition, when female participants competed with same gender opponents in the partner-absent condition, the Alpha frequency band in the IPL exhibited the highest interbrain synchronization. This may be because, at this stage, cognitive empathy has not yet been deeply processed, and the Alpha frequency band reflects only the results of participant visual processing when viewing the same stimulus ( Clements et al, 2023 ). In same gender dyads, both females can guess each other’s intentions given their shared gender and predict their competitors’ subsequent actions, thus reducing the alertness of participant females and their opponents ( Ravreby et al, 2022 ).…”

Competition is a common occurrence in life, but the influence of intimate relationships on people’s competitiveness remains unknown. Grounded in Darwin’s theory of sexual selection, this study utilized EEG hyperscanning technology to investigate the influence of the presence of romantic partners and the gender of competitors on the interbrain synchronization of female individuals during competitive contexts. The research results showed that in competitive interactions, there was a significant increase in Theta and Alpha frequency band activity between females and their competitors. Interbrain synchronization was strongest when their partners were not nearby and females competed with same gender competitors. The research results indicate that intimate companionship has an impact on the early alertness and late cognitive execution mechanisms of female individuals in competition, and due to intimate relationships, females pay more attention to same-gender competitors. This study demonstrates that the presence of intimate partners can affect a female’s competitive state and brain synchronization with opponents of different genders, improving the theoretical explanation of intimate relationships and competitive interactions.

“…In this study, in the early stage of stimulus presentation, when female individuals competed with samesex individuals without their partners, the alpha frequency band near the IPL had the highest degree of brain synchronization. This may be because, at this stage, empathy cognition has not yet been deeply processed, and the alpha frequency band only re ects the results of individual visual processing when viewing the same stimulus (Clements et al, 2023). As women, both sides of the competition can guess each other's intentions from a familiar perspective of their gender and predict their competitors' subsequent actions, thus reducing the alertness of individual women and their opponents (Ravreby et al, 2022).…”

Interbrain synchronization is considered the foundation of consciousness. When people jointly complete a social interaction, there is an inevitable overlap in their cognitive activities; brain synchronization is also considered a sign of individuals completing social interaction together. Based on Darwin's sexual selection theory, this study explored the influence of intimate relationship lover's companionship on female individual competitive interaction and peer brain coupling with competitors through EEG hyperscanning technology, using visual cue-target paradigm and taking inter-brain synchronized phase lock value (PLV) as a measurement index. The research results showed that in competitive interactions, there is a significant increase in theta and alpha frequency band activity between women and their competitors' brains. Brain synchronization is strongest when lovers are not around and women compete with same-sex competitors. In addition, there was a significant negative correlation between brain synchronization and behavioral DRT. The research results indicate that intimate companionship impacts the early alertness and late cognitive execution mechanisms of female individuals in competition. Women tend to focus on competitive tasks when their partner is not around. Moreover, due to intimate relationships, women in the romantic group pay less attention to opposite-sex competitors, while they pay more attention to same-sex competitors. This study demonstrates the impact of intimate relationship partner companionship status and opponent gender on individual female competition and improves the theoretical explanation of intimate relationships and competitive interaction.
