Theses and Dissertations

The literature shows equivocal results regarding the efficiency of TI, but there is limited literature indicating the effects on level of problem behavior. The current study extended the literature on TI by comparing the efficacy and efficiency of varying TI ratios implemented in early intervention practices with children with ASD and related disorders on acquisition and levels problem behavior. The four ratios of mastered …
