Results indicated that, for all but one of eight autistic children, visual discriminations were acquired significantly faster, with fewer errors, when the S+ stimulus was faded first. These findings are related to the literature on the effects of stimulus novelty on selection and learning. (Author/RH)

Compared the performance of children with and without autism in object-based positive and negative priming tasks within a visual search procedure. Found object-based positive and negative priming effects in both groups, with no group differences in the magnitude of the effects. Compared to typically developing children, children with autism were…

Fifteen autistic and 15 normal Ss were trained to respond to a card containing two visual cues. The children were further tested on the single cues in order to assess whether one or both stimuli had acquired control over their responding. (Editor/RK)

Examined were the effects of number of stimuli and of two different stimulus modalities on the discrimination learning of 17 autistic children (mean age 57 months). Discrimination training was carried out in three groups with varied light and sound stimuli. Among findings was that mental age was negatively correlated with trials to criterion and…
