Abstract

Abstract This investigation assessed the physiological stress response through heart rate variability (HRV) during the Implicit Association Test (IAT) with 49 participants. Each participant completed the Big-Five Inventory and a Gender questionnaire before undergoing the IAT, during which HRV was continuously monitored. The analysis revealed no significant differences in HRV between the congruent and incongruent trials of the IAT, indicating that the IAT did not induce measurable physiological stress differences between these conditions. Additionally, neither neuroticism nor conscientiousness significantly influenced HRV outcomes. Furthermore, the study observed nonsignificant correlations between HRV and Self-Assessment Manikin (SAM) scores, challenging the assumed relationship between physiological and perceived stress. These findings suggest that the IAT, as utilized in this study, may not be as effective in inducing a robust stress response compared to more conventional stressors. This highlights a need for further research with a more diverse participant pool and alternative stress induction methods to better understand the dynamics of stress responses in psychological testing. Keywords: Implicit Association Test, heart rate variability, stress response, physiological stress, neuroticism, conscientiousness, personality traits.
