Research is equivocal on whether attention orienting is atypical in autism. This study investigated two types of attention orienting in autistic people and accounted for the potential confounders of alerting level, co-occurring symptoms of attention-deficit/hyperactivity disorder (ADHD) and anxiety, age, and sex. Twenty-seven autistic participants…

Past research has demonstrated a transformation of stimulus functions under similar conditions using gambling tasks and adults (e.g., Zlomke & Dixon, 2006), and the present study attempted to extend this research. Experimenters exposed 7 children (ages 7 to 10 years) to a simulated board game with concurrently available dice differing only by…

Errorless learning refers to a variety of discrimination learning techniques that eliminate or minimize responding to incorrect choices. This article describes experimental roots of errorless learning and applied errorless strategies. Specifically, previous research on stimulus fading, stimulus shaping, response prevention, delayed prompting,…

The present investigation was conducted to determine if stimulus overselectivity in 19 autistic children (5 to 12 years old) is changed as a function of repeated exposure to testing. (Author/SBH)

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)

Color and form preferences of kindergarten, first and third grade Ss were tested using standard two-dimensional geometric forms. (Author)

Experiment I was designed to demonstrate that young children fail to abstract the positive cue as the relevant stimulus event in a restricted concept-learning task. Sixteen kindergarten and 16 fourth grade subjects were trained to criterion on a Kendler-type task, whereupon each subject was presented a pair of new instances which contrasted only…
