This study examined bidirectional interactions between emotional language and inhibitory processes, revealing that setting an inhibition state modulates the processing of negatively charged emotional stimuli. The results suggest a mutual facilitation between inhibitory control and negative valence, supporting recent integrative theories of cognition-emotion interactions.
There is abundant literature demonstrating that processing emotional stimuli modulates inhibitory control processes. However, the reverse effects, namely, how cognitive inhibition influences the processing of emotional stimuli, have been considerably neglected. This ERP study tries to fill this gap by studying the bidirectional interactions between emotional language and inhibitory processes. To this end, participants read emotional sentences, embedded in a cue-based Go-NoGo task. In Experiment 1, the critical emotional adjective preceded the Go-NoGo visual cue. The ERPs showed a significant reduction in the inhibition-related N2 component in NoGo trials when they were preceded by negative adjectives, compared to positive or neutral adjectives, indicating a priming-like effect on inhibitory control. Consistently, the estimated source of this interaction was the dorsomedial PFC, a region associated with inhibitory and control processes. In Experiment 2, the Go-NoGo cue preceded the emotional adjective, and the ERPs showed a sustained, broadly distributed LPP-like positivity for NoGo negative trials, relative to all the other conditions. In this case, the presetting of an inhibition state modulated the processing of negatively charged words. Together, the two experiments suggest a mutual facilitation between inhibitory control and negative valence, supporting thereby recent integrative theories of cognition-emotion interactions.
