This book was released on 2016 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preference assessments have been proven to be an effective assessment that is often used to determine preferences for individuals with developmental disabilities. The multiple stimulus without replacement preference assessment was used with typically developing children. The current study compared assessors of the preference assessments: familiar and non-familiar. There were five participants exposed to a total of ten sessions. The researcher wanted to see if there was a consistency among the rank order of the items chosen across sessions with the familiar person administering the preference assessment. The researcher also wanted to see if the items chosen as reinforcers were different when the familiar person was the assessor compared to the non-familiar person. The results of the current did not support the hypothesis due to the variability between the rank orders of the items chosen and the assessors. There are several limitations that may have contributed to the findings that were discussed such as not using a reinforcer assessment to confirm the validity of the reinforcing value of the selected item.

This book was released on 2017 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preference assessments have been proven to be an effective assessment tool used to identify preferences for individuals with developmental disabilities. There are 4 methods of preference assessments: single-stimulus preference assessment, paired-stimulus preference assessment, multiple stimulus with replacement preference assessment, and multiple stimulus without replacement preference assessment. The current study used the multiple-stimulus without replacement preference assessment to compare identified stimuli across 2 different environments. There were 12 participants exposed to a total of 10 sessions, 5 at home and 5 at school. The research tested for consistency among participant preference of the items chosen across sessions in both locations. The results of the current study were inconclusive; some participants had the same preference across environments and other participants did not have a clear preference in either environment. There were several limitations that may have contributed to the findings. Some of the limitations include the participants’ wide range of abilities and disabilities in the scope of their autism. Other limitations include the inability to insure the participants were not over exposed or satiated on the edible items used. Also, some participants did not have a clear preference for items.

This book was released on 2020 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiple-stimulus without replacement preference assessments (MSWO) have been well-documented in the literature as evidence-based methods of identifying possible reinforcers to occasion desired behavior (e.g., task completion) for individuals with and without disabilities. Stimuli included in the MSWO are typically chosen through structured interviews, arbitrary experimenter selection, observation, informal interview with caregivers or teachers, or self-report. Based on systematic review on preference assessments with adolescents with autism or developmental disabilities, stimuli for the MSWO are primarily selected based on informal report by relevant stakeholders, or inclusion procedures are not specified. Only two out of thirty studies used student self-report of preferences to identify stimuli for inclusion. While MSWOs are efficacious, the methods by which the initial stimuli are selected for an MSWO array are highly variable or not described in the extant literature, limiting the effectiveness of interventions.This study sought to elucidate a standard for stimulus inclusion methods for adolescents with autism and other developmental disabilities. Using a single-case multi-element design, four adolescent boys with autism completed MSWOs based on the various methods of identifying stimuli for the array. Reinforcer assessments were conducted to verify the most effective stimulus inclusion procedure. The identified highest preferred stimuli were delivered contingent on completion of each participant's individualized academic work. Task performance was compared using percentage of differentiation. A social validity measure was administered to stakeholders.Results indicated that for all four participants, informants endorsed vastly different stimuli for inclusion in MSWOs. When comparing these stimuli, however, there was no differentiation in the reinforcer assessment for time to task completion. One participant engaged in rates of noncompliance that differentiated between informants and the control condition. Therefore, no uniform standard for stimulus selection was identified. Acceptability data indicate that all participants were satisfied with the preference assessment procedures and found that making choices was important for the adolescents. These results suggest that it is incumbent upon those who work with adolescents on the spectrum to gather report from multiple informants to ascertain an appropriate range of possible reinforcers. Factors contributing to the efficacy of various stimulus inclusion methods are discussed.

This book was released on 2016 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This experiment evaluated the differential effects of three Multiple Stimulus With Replacement preference assessment variations on the motivation of four participants with developmental disabilities to respond to a mastered task. No discernible difference was demonstrated between the Five Pre-Session Choices condition and the Five Within-Session Choices conditions, suggesting that the timing of choice opportunities did not affect motivation, demonstrated through lack of differentiation in a multi-element experimental design for the dependent variables of Latency to Task Initiation, Total Task Duration, Percentage Correct Responding, or No-Responses. Subsequently, a One Pre-Session Choice condition was initiated to evaluate the efficacy of a preference assessment method with lower practitioner response effort. The introduction of this condition also resulted in undifferentiated data. Implications and future research are discussed.

Download or read book Examination of Choice Overload During Stimulus Preference Assessments written by Jeffrey R. Miller and published by . This book was released on 2012 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Choice overload is characterized by individuals experiencing a decrease in preference strength and satisfaction (Chemey, 2003) in conjunction with increases in disappointment and regret regarding a chosen option (Schwartz, 2000). Choice overload has been examined in a variety of situations, however choice overload has not been examined with individuals with developmental disabilities or during stimulus preference assessments. While extensive research has been conducted regarding stimulus preference assessments, no research has been conducted evaluating the most effective number of items to use during preference assessments. The purpose of the present study was to compare using six and 18 item arrays during a multiple stimulus without replacement preference assessment, to evaluate the accuracy of both procedures with a reinforcer assessment, and to evaluate the behavior of participants for characteristics of choice overload during the preference and reinforcer assessments. The results of the present study suggest that the results between the six and 18 item preference assessments are strongly consistent; however the six item assessments overestimated the reinforcer efficacy of numerous items in comparison to the 18 item preference assessment. The results also suggest that two participants displayed characteristics associated with choice overload and that a certain level of cognitive functioning may be required for choice overload to occur.

Book excerpt: "The results of a function-based multiple stimuli without replacement (MSWO) assessment and a paired-choice assessment (PC) were compared to determine whether the same stimuli options were identified. The two assessment procedures were conducted in a school setting with three participants who engaged in frequent problem behavior. An Assistant Behavior Analyst (BCaBA) served as the therapist for all phases of the assessments. Both the PC and MSWO assessment procedures identified the same stimuli option for all three participants. Strengths and limitations of the study are discussed as well as suggestions for future research."--Abstract.

Download or read book Evaluation of the Rate of Challenging Behavior Maintained by Different Reinforcers Across Three Preference Assessments written by Soyeon Kang and published by . This book was released on 2011 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preference is commonly incorporated into educational interventions for individuals with developmental disabilities. Preference assessments have a solid research base indicating that they are more reliable tools for finding preference than the subjective opinions of parents and teachers. As evidence-based practices have been emphasized, the preference assessment has been a regular component of interventions and instructional programs for the population. Along with the utility, research regarding the assessment and relevant variables has also increased. However, many questions still exist and wait for more inquiry. One of the practical issues is the occurrence of challenging behaviors of individuals with disabilities during preference assessments. Highly occurring challenging behavior during an assessment may interrupt the procedure and lead to inaccurate results about the individual's preference. That may ultimately affect the effectiveness of the intervention or instructional program. Using a procedure that does not evoke challenging behavior is necessary for accurate results as well as ethically responsible. Therefore this study examined the relation between functions of challenging behavior and three commonly used preference assessment procedures: Paired-Stimulus (PS), Multiple-Stimulus without Replacement (MSWO), and Free-Operant (FO). This study had two phases: Functional analyses and preference assessments. First, functional analyses were conducted to identify the function of challenging behaviors. The participants were nine children with developmental disabilities whose functional analysis results indicated their challenging behavior was maintained by access to tangible items (5), attention (2), and escape (2) reinforcers. After identifying the behaviors' functions, preference assessments were implemented to compare the rates of the challenging behaviors. Each preference assessment format was conducted 5 times, in a random order for each participant. The results of the study demonstrate that the occurrence of challenging behavior with different functions was different depending on procedure formats. This suggests that there would be a relation between functions of challenging behavior and preference assessment formats. In other words, depending on the function of challenging behavior, the assessment procedure may act as a trigger evoking the challenging behavior. This study discussed practical guidance to prevent challenging behavior during preference assessments.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Three children with mental retardation and/or autism participated in a study evaluating the reinforcing effectiveness of moderate- and low-preference stimuli. Nine full array Multiple-Stimulus Without Replacement (MSWO) preference assessments were conducted assessing tangible and edible stimuli. The items categorized as moderate- and low-preference using the Ciccone, Graff, and Ahearn (2005) point weighting scoring method were reassessed. The items ranked high-, moderate-, and low-preference from the assessments were then evaluated during the reinforcer assessments. An alternating treatments design was implemented and data were compared to baseline using an A-B design. Two participants' responding increased as the low-, moderate-, and high-preference reinforcement contingencies were implemented. For one participant, the moderate- and high-preference stimuli produced responding at 100%. One participant had minimal responding relative to baseline across all three stimuli. This study extends previous research by demonstrating the MSWO is an effective and efficient technique to identify reinforcers.

Available in PDF, EPUB and Kindle. Book excerpt: Previous researchers have found that individuals with intellectual and developmental disabilities tend to prefer edible over leisure stimuli and that leisure stimuli generally function as less effective reinforcers than edible stimuli, regardless of the preference patterns observed during a combined-class multiple-stimulus without replacement (MSWO) assessment. However, researchers have often arbitrarily selected items to include in these preference assessments and have not investigated this phenomenon with typically developing children. In Study 1, we evaluated the preference for leisure and edible stimuli in a combined-class MSWO assessment with 15 typically developing children. Five of 15 participants preferred edible stimuli over leisure stimuli, 3 of 15 participants preferred leisure stimuli over edible stimuli, and the remaining seven of 15 participants did not prefer one stimulus class over another. In Study 2, we compared the reinforcer potency of displaced stimuli and the stimuli that displaced them with 7 of 8 participants who showed displacement of one stimulus class over the other. Four of 7 participants allocated more responding to the free-operant task associated with the top-ranked stimulus identified in the combined-class MSWO, while 3 of 7 participants showed no differences in responding to the free-operant task regardless of ranking of the reinforcer delivered.

Available in PDF, EPUB and Kindle. Book excerpt: The identification of preferred and reinforcing stimuli has long been a focus of behavior analysts in applied settings. Research has primarily focused on different methodologies for assessing whether stimuli are preferred and there has been additional research on identifying under what conditions those stimuli will function as reinforcers. Recently, research has begun to examine responses and reinforcers from a behavioral economic perspective. The present study compared responding in a situation where the price of one item was increased, but the price of alternative items remained the same, to a situation where the price of all available items increased. Multiple stimulus with replacement (MS) preference assessment methodology was used and price was altered by increasing the distance of the stimuli from the participant. During the first assessment, the item chosen most frequently in the first session was systematically moved 6 - 24 inches beyond the other items during subsequent sessions. During the second assessment, all items were systematically moved 6 - 24 inches beyond the starting point in front of the participant during subsequent sessions. Results for the first assessment indicated that for four of the five participants, consumption of the target item decreased as a function of increased price for that item. Results for the second assessment indicated that at high costs, clear preference for one item was observed for three of the five participants. Taken collectively, these results suggest that response effort is a variable that should be taken into consideration when evaluating effective treatments for individuals with disabilities. Preference and reinforcer effectiveness may shift as individuals are presented with tasks that require increased response effort in terms of reaching or moving about their environment.

Available in PDF, EPUB and Kindle. Book excerpt: This study replicated the response-restriction free-operant procedures of Hanley et al. (2003) and expanded their study by comparing the results to that of a paired choice and multiple stimulus without replacement preference assessments. I also compared the results to a modified version of the Hanley et al. procedures. A statistical analysis was conducted with the hierarchies identified from each assessment using the Spearman Rank order to measure the correlation within and across participants. Finally, I analyzed the results of 32 free operant preference assessments to identify at what point preference was identifiable.

Available in PDF, EPUB and Kindle. Book excerpt: Preference assessments are effective assessments that can be used to determine preferences for individuals with developmental disabilities. The two preference assessment methods are: approach-based and engagement-based. Engagement-based preference assessments are shorter in duration and associated with fewer problem behaviors when compared to approach-based assessments. The two types of engagement-based preference assessments are single-stimulus and multiple-stimulus engagement preference assessments. The current study compared outcomes of the single-stimulus engagement (SSE) and multiple-stimulus engagement (MSE) preference assessment methods to determine reinforcing value of the items identified during both assessments and occurrences of problem behavior. The results of the preference assessments also demonstrated that the MSE preference assessment was associated with lower occurrences of problem behavior in comparison to the SSE preference assessment. Also, the reinforcer assessments demonstrated that items never engaged with during the MSE preference assessment did act as moderately effective reinforcers for all four participants. The items engaged with at moderate to high levels during the SSE preference assessment did not act as effective reinforcers for two out of the four participants when tested for reinforcing value. There are several limitations that may have contributed to the findings that are discussed..

Download or read book Production and Elimination of Position biased Responding in Stimulus Preference Assessments written by Danika Renee Zias and published by . This book was released on 2015 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Position-biased responding is important to eliminate in stimulus preference assessments because it can lead to invalid assessment outcomes. Past research has demonstrated that manipulating reinforcer quality and magnitude may be effective in eliminating side bias in preference assessments. The purpose of Experiment 1 was to investigate other practitioner-friendly solutions to eliminate bias with children with developmental disabilities. Due to the inability to recruit a participant who met our inclusion criteria, the procedures were not evaluated. Experiments 2 and 3 were conducted to evaluate the effects of effort manipulation on production of positional bias and methods to eliminate bias with four typically developing preschoolers using a translational preparation. The results of these studies suggested that positional bias was produced when effort for making selections to one side of an array was high, and a quality training procedure was effective in eliminating this bias. However, treatment effects did not generalize when quality training was removed.
