Background Variation in EEG‐derived delta–beta coupling has recently emerged as a potential neural marker of emotion regulation, providing novel and noninvasive method for assessing risk factor anxiety. However, our understanding been limited to group‐level comparisons, which provide information about an individual’s dynamics. Methods The present study used multilevel modeling map second‐by‐second patterns between delta beta power. Specifically, we examined how inter‐ intraindividual changed function social anxiety symptoms temperamental behavioral inhibition (BI). Results We found that stronger were both associated with In contrast, the high‐BI group showed weaker relative non‐BI group, pattern did not emerge when analyzing continuous scores BI. Conclusions characterizing across sample, illustrate utility examining processes levels analysis relation psychopathology create assessments functioning risk.
