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…
Parallel Adaptation to Spatially Distinct Distortions
2020
Optical distortions as a visual disturbance are inherent in many optical devices such as spectacles or virtual reality headsets. In such devices, distortions vary spatially across the visual field. In progressive addition lenses, for example, the left and right regions of the lens skew the peripheral parts of the wearers visual field in opposing directions. The human visual system adapts to homogeneous distortions and the respective aftereffects are transferred to non-retinotopic locations. This study investigates simultaneous adaptation to two opposing distortions at different retinotopic locations. Two oppositely skewed natural image sequences were presented to 10 subjects as adaptation s…
Artificial faces predict gaze allocation in complex dynamic scenes
2019
Both low-level physical saliency and social information, as presented by human heads or bodies, are known to drive gaze behavior in free-viewing tasks. Researchers have previously made use of a great variety of face stimuli, ranging from photographs of real humans to schematic faces, frequently without systematically differentiating between the two. In the current study, we used a Generalized Linear Mixed Model (GLMM) approach to investigate to what extent schematic artificial faces can predict gaze when they are presented alone or in competition with real human faces. Relative differences in predictive power became apparent, while GLMMs suggest substantial effects for real and artificial f…
