We extended past observational learning research by incorporating stimuli already known to participants into training. We used a multiple-baseline design across three participants to determine the effects of discrimination training on the discrimination of consequences applied to modeled responses using both known and unknown pictures. During…

This study was a systematic replication and extension of Fisher, Kodak, and Moore (2007), in which a picture prompt embedded into a least-to-most prompting sequence facilitated acquisition of auditory-visual conditional discriminations. Participants were 4 children who had been diagnosed with autism; 2 had limited prior receptive skills, and 2 had…

Previous research indicates that pairing pictures with associated words when teaching sight-word reading may hinder acquisition (e.g., Didden, Prinsen, & Sigafoos, 2000; Singh & Solman, 1990; Solman & Singh, 1992). The purpose of the current study was to determine whether this phenomenon was due to a previously learned association between the…

We evaluated the influence of two different frequencies of data collection on skill acquisition and maintenance within behavioral treatment programs for children with autism spectrum disorders. Six children were taught multiple skills in up to four different behavioral programs. Half of the skills were measured continuously (i.e., trial by trial),…
