Attentional and electrophysiological associations with executive function ability in young autistic children

Difficulties in executive functioning (EF) have been consistently reported in autistic individuals, but less is known about the attentional and neural mechanisms driving these difficulties. We explored the associations between EF abilities and sustained attention, measured with eye-tracking, and spontaneous measures of EEG spectral power density in 176 2-8 year-old autistic children with a wide range of cognitive abilities. EF was measured using the Behavior Rating Inventory of Executive Function (BRIEF). We found that EF abilities were positively associated with look durations while watching complex, audiovisual stimuli involving social content and dyadic speech. We also found that EF was negatively associated with scalp-wide theta power and positively associated with frontal beta and gamma power. These results shed light on attentional and neural associations with EF abilities and underscore the role of frontal brain activity for EF in autism.
