Recognizing Biological Motion and Emotions from Point-Light Displays in Autism Spectrum Disorders
One of the main characteristics of Autism Spectrum Disorder (ASD) are problems with social interaction and communication. Here, we explored ASD-related alterations in 'reading' body language of other humans. Accuracy and reaction times were assessed from two observational tasks involving the recognition of 'biological motion' and 'emotions' from point-light displays (PLDs). Eye movements were r...
متن کاملDepth perception from point-light biological motion displays.
Humans have a clear impression of facing in depth for point-light biological motion. However, this has not been measured systematically nor is it known on which cues humans rely for their judgment. In the present study subjects judged the facing orientation-in-depth of point-light displays. The displays represented natural walking and modified versions in which the time sequence was reversed, a...
متن کاملIQ predicts biological motion perception in autism spectrum disorders.
Biological motion is easily perceived by neurotypical observers when encoded in point-light displays. Some but not all relevant research shows significant deficits in biological motion perception among those with ASD, especially with respect to emotional displays. We tested adults with and without ASD on the perception of masked biological motion and the perception of direction from coherent an...
متن کاملPerception of biological motion in autism spectrum disorders.
In individuals with autism or autism-spectrum-disorder (ASD), conflicting results have been reported regarding the processing of biological motion tasks. As biological motion perception and recognition might be related to impaired imitation, gross motor skills and autism specific psychopathology in individuals with ASD, we performed a functional MRI study on biological motion perception in a sa...
متن کاملSensitivity to motion features in point light displays of biological motion.
Psychophysical experiments are described that measure the sensitivity to motion features in point light displays of biological motion. Three motion features were investigated: the relative motion of the thighs, the relative motion of the thigh and leg, and the velocity profile of the leg. The perceptual threshold for discriminating a change in each motion feature was compared in upright and inv...
