RESUMO
The auditory gaze cueing effect (auditory-GCE) is a faster response to auditory targets at an eye-gaze cue location than at a non-cue location. Previous research has found that auditory-GCE can be influenced by the integration of both gaze direction and emotion conveyed through facial expressions. However, it is unclear whether the emotional information of auditory targets can be cross-modally integrated with gaze direction to affect auditory-GCE. Here, we set neutral faces with different gaze directions as cues and three emotional sounds (fearful, happy, and neutral) as targets to investigate how the emotion of sound target modulates the auditory-GCE. Moreover, we conducted a controlled experiment using arrow cues. The results show that the emotional content of sound targets influences the auditory-GCE but only for those induced by facial cues. Specifically, fearful sounds elicit a significantly larger auditory-GCE compared to happy and neutral sounds, indicating that the emotional content of auditory targets plays a modulating role in the auditory-GCE. Furthermore, this modulation appears to occur only at a higher level of social meaning, involving the integration of emotional information from a sound with social gaze direction, rather than at a lower level, which involves the integration of direction and auditory emotion.
RESUMO
Recent studies have found that face masks affect social cognition and behaviour in the context of the novel coronavirus (COVID-19) pandemic. The eyes, the only part of the face not covered by face masks, are an important spatial attention cue that can trigger social attention orienting. Here, we adopted a spatial gaze-cueing task to investigate whether face masks affect social attention orienting triggered by eye gaze cues. In Experiment 1, participants were asked to determine the orientation of a target line under two types of cues-masked and non-masked faces-and two stimulus onset asynchrony (SOA) conditions (300 ms and 1000 ms). The results showed that masked faces induced a smaller gaze-cueing effect (GCE) compared to non-masked faces at 300 ms SOA, while two face types induced similar GCEs at 1000 ms SOA. Experiment 2 used mouth-obscured faces and non-masked faces as cues and found that no significant difference in GCE between the two types at either 300 ms or 1000 ms SOA, indicating that the reduction of GCE caused by the masked face was due to the social meaning expressed by the mask rather than a physical effect of masking. The present study extends previous findings to support the idea that high-level social information affects the processing of eye gaze direction and provides evidence that face masks affect social cognition and behaviour in the context of COVID-19.
