A study from Texas indicates that Neurologically Typical persons make robust judgments about persons with Autism Spectrum Disorders from seeing or hearing them speak. These judgments take only a few seconds to make; they also suggest that persons with ASDs are less approachable, more awkward, less likely to start a conversation, more likely to spend time alone, and less likely to get along well with others than their NT peers. Many of these findings are significant at the 0.001 level--there is less than one chance in a thousand that these findings could be due to chance alone.
