The trait emotional intelligence (EI), as lower personality trait, influences one's information processing ability. However, under stress situation, the depth of processing is different due to different pressure influences. The current study paid attention to how the trait EI affects memory bias and attentional bias under stress situation. Experiment 1 was designed to examine how the trait EI affects memory bias under stress situation. The design was 2 (group type: pressure group, control group) × 2 (trait EI type: high, low) randomized block design. Firstly, all the participants filled in the positive and negative affect scale (PANAS) to measure their the emotional state and the short form of questionnaire of trait of emotional intelligence to distinguish who has the high or low emotional intelligence; then, in the pressure condition, participants were induced stress through China Civil Service examination, while participants in the control condition were under general experimental material. After that, all participants performed autobiographical recall tasks (including content of memories, potency and potency evaluation). Experiment 2 was designed to examine how the trait EI affects attention bias under stress situation; the design and procedure was similar to Experiment 1, except for that a modified dot probe paradigm was used to measure the attentional bias. The results showed that under pressure situation, high trait emotional intelligence individuals bias toward processing positive memory and attention positive vocabulary, while low trait emotional intelligence individuals bias toward processing negative valence memory and attention negative vocabulary; but under control situation, both high and low trait emotional intelligence individuals did not have such memory or attention bias. These results of two experiments illustrated that trait EI has moderating effect and can buffer the influence of stress on information processing. The current study sheds light on how the trait emotional intelligence adjusts the pressure of information processing.
