The role of attentional biases to appetitive stimuli in childhood overweight
2018
Overweight during childhood constitutes a high-risk factor for adult obesity. An abnormal attention to food stimuli (i.e., a bias) has been suggested as an underlying mechanism to the onset and/or maintenance of obesity. Previous literature supports the existence of a biased attention toward food stimuli in adults with obesity. However, it is unknown whether this attentional bias occurs in high-risk children for adult obesity. We aimed to examine attentional biases to food at different stages of attention processing in overweight children. A dot-probe task was applied to 25 children with overweight and 25 healthy-weight children (8-12 years old). Attentional preference to or avoidance of pl…
Modulation of attention by socio-emotional scenes in children with autism spectrum disorder
2017
Background: Abnormal attentional processes to socially relevant information may underlie social impairment in Autism Spectrum Disorder (ASD). To examine how these processes are modulated by the emotional salience of the stimuli, we studied the attentional biases to social scenes (happy, sad, and threatening) in ASD children. Method: An emotional dot-probe task was applied to children (from 6 to 12 years old) with Autism Spectrum Disorder without additional language and/or intellectual impairments (ASD; n=25) and age/sex-matched controls (n=25). Results: ASD children showed an attentional bias toward threatening scenes while typically developing children tended to direct their attention towa…
