Background and aims: Understanding the emotional state of others is fundamental to effective social interaction and the development of empathy. Critical information is conveyed via the eyes, and reduced attention to the eyes is associated with poorer emotion recognition and empathic deficits in individuals with disorders affecting social cognition such as autism or some types of conduct problems. Deliberately redirecting attention to the eyes may be a way of improving behaviour. However, the effects of directing attention on brain activity during emotional processing has not been studied previously. Our aim was to determine whether manipulation of visual attention in youths affects their eye gaze patterns and brain responses to expression of emotions in others.
Method: Eighteen typically developing male youths aged 8-16 performed an implicit facial emotion processing task while viewing different facial expressions (fearful, neutral, happy), presented in three separate blocks under three different instructions: undirected, eye-gaze and mouth-gaze. Eye tracking (dwell time) and functional-MRI data were acquired concurrently as measures of visual attention and brain response, respectively.
Results: Eye tracking indicated that the youths attended more to the eyes than the mouth in the undirected condition. Redirecting attention to the eyes and mouth significantly increased attention to these areas. Compared to undirected, directing attention to the fearful eyes also produced a greater increase in attention than neutral eyes. Attention directed to eyes elicited greater brain activity in frontal regions than undirected attention.
Conclusions: The undirected eye gaze patterns indicate natural orienting to eyes in healthy youths, which can be effectively altered with instruction. Directing attention to fearful eyes engaged attention relatively longer than neutral, consistent with the threat value of fearful faces. These data also demonstrate that manipulation of visual attention modulates activity in frontal regions, perhaps reflecting greater engagement of executive function due to attentional demands. Understanding attentional manipulation effects in a healthy sample will inform ongoing work addressing potentially perturbed response patterns in a conduct problem cohort.
