Extinction of over-selected stimuli causes emergence of under-selected cues in higher-functioning children with autistic spectrum disorders . Two experiments examined whether over-selectivity is the product of a post-acquisition performance deficit , rather than an attention problem . In both experiments , children with Autistic Spectrum Disorder were presented with a trial-and-error discrimination task using two , two-element stimuli and over-selected in both studies . After behavioral control by the previously over-selected stimulus was extinguished , behavioral control by the previously under-selected cue emerged without direct training . However , this effect was only found in higher-functioning children , and not with more severely impaired children . These findings suggest that over-selectivity is not simply due to a failure to attend to all of the stimuli presented . They also suggest that extinction of over-selected stimuli may be a fruitful line of intervention for clinical intervention for some individuals .
