# Contextual cues shape facial emotion recognition: a combined behavioral and ERP study

## TL;DR

This study shows how contextual cues influence facial emotion recognition, using both behavior and brain activity measurements.

## Contribution

The study reveals how contextual congruency and emotional valence modulate facial emotion recognition through multi-stage processing.

## Key findings

- Participants responded faster and made fewer errors in congruent trials compared to incongruent ones.
- Incongruent cues elicited a larger P1 component, indicating increased early attentional resources.
- Negative stimuli elicited a larger P3 component than neutral ones, highlighting emotional valence in cognitive processing.

## Abstract

Being able to recognize the emotions in others is fundamental to social interaction, yet the precise temporal dynamics by which the brain integrates contextual cues with facial expressions remain unclear. This study used behavioral measures and event-related potentials (ERPs) to investigate how contextual congruency and emotional valence modulate facial emotion recognition in a neurotypical population.

Participants viewed emotional faces preceded by either congruent or incongruent bimodal cues, combining vocalizations and visual images.

Behaviorally, participants responded faster and made fewer errors during congruent trials than in incongruent trials, indicating that context facilitates emotional processing. At the neural level, incongruent cues elicited a significantly larger P1 component, suggesting that the brain allocates increased early attentional resources to conflicting stimuli. Furthermore, the P3 component was significantly larger for negative stimuli compared to neutral ones, highlighting the role of emotional valence in later stages of cognitive processing.

Together, these findings support a multi-stage model of emotional integration, where contextual incongruency impacts processing from early perceptual encoding to later cognitive evaluation. By integrating behavioral and neural evidence, this study clarifies the temporal course of contextual integration in multisensory emotion perception and provides new insights with implications for clinical and applied research.
