The purpose of the present study is to assess the relationship between individual differences in resilience (emotional regulation) and EEG power spectra and EEG connectivity. The study included 20 healthy participants, ranging in ages between 18 to 60 years, who consented to having their EEG recorded before and after two psychological stressors (Serial 7’s and the Stroop test) were applied. Each subject participated in one standard, safe, non-invasive 10 minute ‘eyes open’ EEG recording from sensors pasted on the scalp while sitting quietly. Subsequently, additional 5-minute EEG recordings were taken before and after the application of the two stressors. EEG analysis was conducted by an Analysis of Variance (ANOVA).
The results of the study did not detect a significant association between hemispherical alpha or beta in participants reporting low or high resiliency. Several limitations in this study limit the interpretation of these findings, , including: (1) a small sample size; (2) adequacy and intensity of the stressor being applied; (3) timing of post EEG assessment; and (4) the use of standard alpha band instead of individual peak alpha frequency.
Future research would benefit from including a wider range of participants and ensuring there are enough individuals who classify as low or high resiliency.
