Conditional Discrimination in the Intraverbal Relation: A Review and Recommendations for Future Research

Conditional discrimination is inherent in the intraverbal relation when one verbal stimulus alters the evocative effect of another verbal stimulus and they collectively evoke an intraverbal response. Rarely in research on conditional discriminations have both conditional and discriminative stimuli been vocal verbal and rarely have the responses been topography-based. Making conditional discriminations in intraverbal behavior is a repertoire that is often delayed in children with autism and other developmental disabilities. Reviewed in this paper is research on teaching intraverbal behavior, auditory conditional discriminations, and restricted stimulus control. The purpose of these reviews is to identify the extent to which previous researchers examined conditional discriminations in the intraverbal relation and to recommend directions for research in this area.

MATRIX TRAINING OF PRELITERACY SKILLS WITH PRESCHOOLERS WITH AUTISM

Matrix training is a generative approach to instruction in which words are arranged in a matrix so that some multiword phrases are taught and others emerge without direct teaching. We taught 4 preschoolers with autism to follow instructions to perform action-picture combinations (e.g., circle the pepper, underline the deer). Each matrix contained 6 actions on 1 axis and 6 pictures on the other axis. We used most-to-least prompting to train the instructions along the diagonal of each matrix and probed the untrained combinations. For 2 participants, untrained responding emerged after the minimum amount of training. The other 2 participants required further training before untrained combinations emerged. At the end of the study, 3 of the 4 participants performed the trained actions with previously known pictures, letters, and numbers. This study demonstrated that matrix training is an efficient approach to teaching language and literacy skills to children with autism.

A Comprehensive Inclusion Program for Kindergarten Children with Autism Spectrum Disorder.

To date, reports of empirically validated comprehensive intervention programs for children with autism spectrum disorder (ASD) have been limited to preschool-age children. We examined the effects of a model inclusive kindergarten program for children with ASD. Forty-one children received instruction in an inclusive kindergarten program with their peers for 28 hrs a week. A comparison group (n = 21) received an eclectic intervention in public, general education, kindergarten classrooms. Examiners administered standardized tests of cognitive, language, and adaptive behavior skills to children in both groups at the beginning and end of the school year. There were no differences in test scores between the two groups at baseline. Following intervention, the model program group had higher mean standard scores in all skill domains. The differences were statistically significant for all domains except adaptive behavior and spoken language. These findings are consistent with reports of success for inclusive programs for preschool children with ASD.
