Interest surrounding the investigation of autism spectrum disorder (ASD) has increased exponentially since it was initially described over a half-century ago. With this passage of time our conceptualization of the ASD diagnosis has undergone multiple changes. An increasing trend in research has been an emphasis on early identification and intervention. This trend has brought about the creation and adaptation of multiple measures designed to inform early ASD diagnosis. Recently, the ASD diagnostic category underwent significant revisions. In response to revisions, it is necessary to adapt preexisting measures to reflect these significant changes in order to maintain diagnostic accuracy. The Baby …

Prior research has demonstrated the utility of several preference-assessment methodologies to identify stimuli more likely to function as reinforcers for individuals with limited verbal repertoires. However, differing results have been obtained from studies evaluating the reinforcement effects of stimuli identified as high preference by one assessment method but low preference by another assessment method. The first focus of the project was to evaluate the reinforcing efficacy of edible and leisure items based on predictions from preference assessments. Results indicated that edible and leisure items approached frequently during a single-stimulus preference assessment but infrequently during a paired-stimulus preference assessment produced less …
