Abstract:
Micro‐expression recognition is influenced by emotional contexts at the behavioral level. It is found that the recognition for micro‐expressions is poorer following a negative context compared to the recognition following a neutral context. However, it remains unclear whether the modulation takes place in the early or later stage of the processing of micro‐expressions as reflected in event‐related potentials ( ERP s). Using synthesized micro‐expressions in this study, we investigated how emotional context modulates the ERP components that are elicited by micro‐expressions. We observed that, compared to neutral contexts, negative and positive contexts elicited more positive amplitude trends for processing the subsequent target micro‐expressions, and more positive P 1 and N 170 effects were elicited by target micro‐expressions following negative and positive contexts compared to those following neutral contexts. Moreover, there were larger P 1 effects elicited by the target micro‐expressions when the context and target expressions were incongruent compared to when they were congruent. Our findings provide new ERP evidence to indicate that emotional contexts modulate micro‐expression processing, and that the modulation of emotional contexts takes place at the early stage of facial‐expression processing.
