abstract: This study compared a stimulus fading (SF) procedure with a constant time delay (CTD) procedure for identification of consonant-vowel-consonant (CVC) nonsense words for a participant with autism. An alternating treatments design was utilized through a computer-based format. Receptive identification of target words was evaluated using a computer format and the researcher conducted a generalization probe for expressive identification evaluation. Neither treatment condition resulted in consistent gains on the receptive identification measure. Both treatment conditions resulted in gains on the expressive identification assessment. The SF treatment condition was more efficient due to 1) accuracy in identifying all of the SF target words in fewer sessions than the CTD target words and 2) incidental learning that occurred as a result of exposure to additional SF words as distracter choices and in receptive identification assessments. Implications are discussed. / Dissertation/Thesis / Ph.D. Special Education 2011

Targeted interventions support students who are at-risk for developing more severe problem behaviors. These interventions are implemented similarly across a group of students, and thus serve as an efficient and cost effective method of behavior support. Check in Check out (CICO) is a targeted group intervention that has a growing research base supporting its efficacy (Crone & Horner, 2003; Todd, Campbell, Meyer, & Horner, 2008). Although there is a growing research base, no studies have examined maintenance of reductions in problem behavior upon fading. The present study examines (1) if a functional relation exists between CICO and reductions in problem behavior, and (2) which components of CICO can be successfully faded with reductions in problem behavior maintaining. In addition, this study examines if teacher attention varies across phases of the study, and predicts successful fading procedures. A reversal design was used to evaluate the efficacy of CICO and subsequent fading phases in four elementary school aged boys. Results indicated that CICO was functionally related to reductions in classroom problem behavior in all four participants. In addition, a functional relation was established with CICO and increases in academic achievement in three participants. Fading procedures were mildly successful, with only some intervention components being removed with reductions in problem behavior maintaining. The amount of adult attention did not vary across study phases, however adult attention became less dependent on problem behavior during the CICO and first fading phase. Clinical and conceptual implications, as well as future research will be discussed. / Adviser: Cynthia Anderson

De-worming is an important and well-researched part of equine husbandry. However, the de-worming process has been problematic as horses often display avoidance behavior toward the oral administration of the paste. The current study was designed to investigate a force-free method to teach equines to voluntary ingest five novel target stimuli including de-wormer. This method was based on a fading procedure. Participants were initially presented with a highly preferred food stimulus. Over the course of the study, the target stimuli were blended into the highly preferred food stimulus at increasingly higher ratios. By the end of the procedure, only the target stimuli were presented. Four horses participated in the study. After treatment, three of the four horses voluntarily ingested all five target stimuli. The fourth horse voluntarily ingested two novel stimuli and the other three novel stimuli if blended with three quarters of an ounce of pellets. Overall, the procedure was successful and provides a non-aversive alternative to existing de-worming strategies.

Many clients with developmental and/or intellectual disabilities (ID/DD) do not tolerate routine medical or dental procedures and may require intrusive interventions, including restraint of various types (i.e. chemical, mechanical, physical, etc.) during appointments. Graduated exposure, or stimulus fading, along with reinforcement for compliance, have been shown to increase cooperation and tolerance in some clients; however, many do not respond to these types of interventions. Nine participants diagnosed with ID/DD recieved compliance/tolerance training for routine medical or dental procedures. Results of these interventions were evaluated in the context of several potential indices of readiness, such as medical diagnoses, level of disability, and presence of challenging behavior, among others. Several of the variables appeared to be correlated with program responsiveness; however, a larger sample will be necessary to draw definitive conclusions. Client characteristics and past assessments (anecdotals, preference assessments, terminal probes, and survey data) were evaluated. The analytical framework developed for this analysis may be useful to future researchers and clinicians as a model for assessing readiness for tolerance training programs.
