“…Results of this study extend previous research (Ciccone et al, 2015;Hanley et al, 2003;Kenzer et al, 2013) by demonstrating participants often selected unreplenished items but they also selected replenished items if (a) historically preferred items were unavailable and (b) the replenished items were matched to multiple sensory properties of the unreplenished items. These results suggest the importance of including a variety of items in preference assessments for people who demonstrate restricted interests.…”

“…These results suggest the importance of including a variety of items in preference assessments for people who demonstrate restricted interests. This study also extends the work of Kenzer et al (2013) by assessing preferences for unfamiliar items that were replenished frequently (i.e., after a maximum of four selections). Participants in the current study were assesed on at total of 20 to 39 replenished items.…”

“…A minimum of two sessions were conducted per visit up to 5 days per week. Each session included a one-trial choice per pool (three trials total), followed by a one-trial prompted exposure per item (three exposure trials per session), one concurrent-chain worksheet trial (Kenzer et al, 2013), and a reinforceraccess period.…”

Restricted Interests and Autism: Further Assessment of Preferences for a Variety of Leisure Items

Researchers have yet to identify the conditions under which people diagnosed with autism spectrum disorder demonstrate restricted interests; it is possible that the impression of restricted interests is strengthened when a limited variety of items are included in a client's preference assessments. This study will extend past research on preferences of children with autism by (a) examining participants' preferences for unreplenished (familiar) play or leisure items versus items that are replenished frequently, (b) assessing if participants who prefer replenished items select items with properties that are matched or unmatched to their most preferred unreplenished item, and (c) assessing if participants who show an exclusive preference for unreplenished items will select replenished items during response-restriction and enhanced-replenished pool manipulations. Participants were four adolescents with autism and a caregiver-reported history of restricted interests. One participant selected both unreplenished (familiar) items and replenished (novel) items without further manipulations. The remaining three participants only selected replenished-matched leisure items after additional manipulations. Results are discussed in terms of the ethical and practical importance of assessing a range of potential reinforcers, particularly with clients who demonstrate restricted interests.

“…PR schedules have been used for decades in basic research to gauge relative reinforcer effectiveness and have been used increasingly in applied settings as a means to determine the potency of reinforcers for children with ASD and other developmental disabilities (e.g. DeLeon et al, 2009, 2011; Francisco et al, 2008; Glover et al, 2008; Kenzer et al, 2013; Tiger et al, 2010). The procedure yields a break point (BP) as a measure of reinforcer efficacy , defined as the extent to which an individual will work to gain access a stimulus.…”

One of the key diagnostic criteria for autism spectrum disorder includes impairments in social interactions. This study compared the extent to which boys with high-functioning autism and typically developing boys “value” engaging in activities with a parent or alone. Two different assessments that can empirically determine the relative reinforcing value of social and non-social stimuli were employed: paired-choice preference assessments and progressive-ratio schedules. There were no significant differences between boys with high-functioning autism and typically developing boys on either measure. Moreover, there was a strong correspondence in performance across these two measures for participants in each group. These results suggest that the relative reinforcing value of engaging in activities with a primary caregiver is not diminished for children with autism spectrum disorder.

Randomization Tests for Single Case Designs with Rapidly Alternating Conditions: An Analysis of p-Values from Published Experiments

Two common barriers to applying statistical tests to single-case experiments are that single-case data often violate the assumptions of parametric tests and that random assignment is inconsistent with the logic of single-case design. However, in the case of randomization tests applied to single-case experiments with rapidly alternating conditions, neither the statistical assumptions nor the logic of the designs are violated. To examine the utility of randomization tests for single-case data, we collected a sample of published articles including alternating treatments or multielement designs with random or semi-random condition sequences. We extracted data from graphs and used randomization tests to estimate the probability of obtaining results at least as extreme as the results in the experiment by chance alone (i.e., p-value). We compared the distribution of p-values from experimental comparisons that did and did not indicate a functional relation based on visual analysis and evaluated agreement between visual and statistical analysis at several levels of α. Results showed different means, shapes, and spreads for the p-value distributions and substantial agreement between visual and statistical analysis when α = .05, with lower agreement when α was adjusted to preserve family-wise error at .05. Questions remain, however, on the appropriate application and interpretation of randomization tests for single-case designs. Keywords Visual analysis. Statistical analysis. Randomization test. Alternating treatments design. Multielement design. p-value To date, visual analysis has been the standard and accepted method for interpreting results of experimental single-case designs (Kratochwill, Levin, Horner, & Swoboda,
