EV0578 E-PosterNeuroscience and ImagingCross-sectional experimental EEG study (between-group comparison) # Accelerated preattentive detection of pitch deviations in individuals with high social anxiety supports enhanced sensory monitoring of social rank cues ACCELERATED PRE-ATTENTIVE DETECTION OF PITCH DEVIATIONS IN INDIVIDUALS WITH ELEVATED SOCIAL ANXIETY SUPPORTS ENHANCED SENSORY MONITORING OF SOCIAL RANK INDICATORS Presenter: Xiaochen Zhang Country: China Institution: Shanghai Mental Health Center, Shanghai Jiao Tong University Individuals with high social anxiety detect voice pitch deviations significantly earlier and with a stronger mismatch negativity response in the right hemisphere. The study aimed to test whether individuals with high social anxiety show heightened sensitivity in monitoring cues related to social status, particularly voice pitch; the hypothesis was that high social anxiety would manifest as larger mismatch negativity (MMN) amplitudes and shorter MMN latencies. The sample comprised 60 young adults aged 18–30 years (30 women); participants were classified into high and low social anxiety groups according to a predefined criterion derived from the Liebowitz Social Anxiety Scale (LSAS). While participants watched a silent film, four passive auditory oddball conditions—neutral voice, angry voice, neutral tone, and angry tone—were presented during 32-channel EEG recording; stimuli lasted 200 milliseconds, the standard-to-deviant ratio was 6:1, and deviant stimuli were approximately 40 Hz lower in pitch than standard stimuli. MMN was obtained by subtracting responses to matched standard stimuli from responses to deviant stimuli. The high social anxiety group showed a significantly shorter MMN peak latency than the low anxiety group (p < 0.05); the scalp distribution of MMN followed a typical frontocentral pattern, with a more pronounced negative field in the high anxiety group. Although no significant between-group differences were found in the left hemisphere in any time window, the high social anxiety group exhibited stronger MMN amplitudes in the right hemisphere during the 75–100, 100–125, and 125–150 millisecond windows after Bonferroni correction (p < 0.05). In the mediation analysis, the indirect effect of social anxiety on self-esteem through sensitivity to pitch deviation detection was positive (indirect effect = 0.0797, 95% CI [0.0026, 0.1917]), whereas its direct effect was negative (direct effect = -0.549, 95% CI [-4.8202, -0.1974]), as was the total effect (total effect = -0.470, 95% CI [-4.3397, -1.4695]). The authors suggest that enhanced pitch deviation detection may function as a preattentive radar for potential threats to social status and may help individuals avoid negative evaluation or loss of status.
