THERAPIST‐ AND SELF‐MONITORED DRO CONTINGENCIES AS A TREATMENT FOR THE SELF‐INJURIOUS SKIN PICKING OF A YOUNG MAN WITH ASPERGER SYNDROME

The use of differential reinforcement of other behavior (DRO) has decreased, at least partially due to the development of less effortful alternative behavioral interventions (e.g., noncontingent reinforcement; Vollmer, Iwata, Zarcone, Smith, & Mazaleski, 1993). The effort associated with DRO contingencies may be lessened by incorporating self‐monitoring components in which clients are responsible for the delivery of reinforcers for their own behavior. The current study evaluates the effectiveness of DRO in the treatment of self‐injury when implemented first by the therapist and subsequently by the client.     

The Use of Verb Information in Parsing: Different Statistical Analyses Lead to Contradictory Conclusions

The research investigated how comprehenders use verb information during syntactic parsing. Two reading experiments investigated the relationship between verb-specific variables and reading time. These experiments were close replications of prior work; however, two statistical techniques were used, rather than one. These were item-by-item correlations and participant-by-participant regression. In Experiment 1, reading time was measured using a self-paced moving window. In Experiment 2, eye movements were recorded during reading. The results of both experiments showed that the results of two types of statistical analyses support contradictory conclusions. The analyses involving participant-by-participant regression analyses provided no evidence for the early use of verb information in parsing and support syntax-first approaches to parsing. In contrast, the results of item-by-item correlation were consistent with the prior research, supporting the view that verb information can guide initial parsing decisions. Implications for theories of parsing are discussed.

Cognitive consequences of novelty and familiarity: How mere exposure influences level of construal

Two experiments examine whether frequency of exposure influences level of construal. Using subliminal presentation, participants were exposed to neutral, unknown letters 0, 5, 15, or 40 times, and a typical mere exposure effect was found on evaluation. However, we hypothesized and showed in Experiment 1 that novelty enhances Gestalt-like, global perception, whereas familiarity bolsters detail-oriented, local perception. Furthermore, in Experiment 2, we demonstrated that participants generated more abstract solutions for items presented less frequently. These results support a Construal level theory [Liberman, N., Trope, Y., & Stephan, E. (2007). Psychological distance. In E. T. Higgins & A. W. Kruglanski, Social psychology, handbook of basic principles. New York: Guilford Press.] contention that distance from direct experience is associated with high construal level and global processing. It seems that in order to prepare for novel events, people automatically engage in higher levels of construal. New information needs to be integrated into existing knowledge structures in order to be understood, and abstract categories and global processing may support the process of understanding.     

Logical information and epistemic space

Gaining information can be modelled as a narrowing of epistemic space. Intuitively, becoming informed that such-and-such is the case rules out certain scenarios or would-be possibilities. Chalmers’s account of epistemic space treats it as a space of a priori possibility and so has trouble in dealing with the information which we intuitively feel can be gained from logical inference. I propose a more inclusive notion of epistemic space, based on Priest’s notion of open worlds yet which contains only those epistemic scenarios which are not obviously impossible. Whether something is obvious is not always a determinate matter and so the resulting picture is of an epistemic space with fuzzy boundaries.     

The medium can influence the message: Print-based versus digital reading influences how people process different types of written information

While electronic reading devices are extremely popular, research is equivocal regarding their benefits for outcomes such as reader comprehension. Integrating literatures on reading medium comparisons and matching effects in persuasion, this research tested whether comprehension is maximized when the content of the material (e.g., whether it is traditional vs. modern) matches the medium (e.g., reading from a traditional book vs. digital e-reader). In Study 1, participants read a traditional- or modern-themed short story from either a book or an e-reader. Story comprehension was greater when participants read from the printed medium compared to the e-reader, an effect that was marginally moderated by story content, consistent with a matching effect. In Study 2, participants read a persuasive message that emphasized either a traditional versus modern solution to improving health in either a magazine format or on an iPad. Message comprehension was marginally greater among participants who read their message in a printed format. Participants’ interest in weight loss showed evidence of a matching effect – participants were more interested in losing weight when a modern solution to obesity article was presented on an iPad compared to a printed format. The results are applied to the study of reading and attitude change.     

Negative reinforcer magnitude manipulations for treating escape-maintained problem behavior

The purpose of the current study was to evaluate the effects of different magnitudes of escape for compliance relative to the magnitudes of escape for problem behavior in a concurrent-schedule arrangement. Three individuals who exhibited escape-maintained problem behavior participated. A large differential magnitude condition (240-s escape for compliance, 10-s escape for problem behavior) was compared to equal (30-s escape for compliance and problem behavior) and moderate differential magnitude (90-s escape for compliance, 10-s escape for problem behavior) conditions. The authors also evaluated the impact of correcting for reinforcer access time (i.e., time on escape intervals) on intervention interpretation. For all participants, problem behavior decreased during only the large differential magnitude condition, and including reinforcer access time in the overall session time did not affect interpretation of treatment outcomes. Providing larger escape magnitudes for compliance relative to problem behavior may facilitate treatment involving concurrent-reinforcement schedules for escape-maintained problem behavior.     

Differential reinforcement-of-low-rate procedures: A systematic replication with students with autism spectrum disorder

Becraft, Borrero, Davis, Mendres-Smith, and Castillo (2018) studied the effects of two different types of DRL schedules (full session and spaced responding) under 2 sets of stimulus conditions (with and without signals). Reduced rates of responding maintained under both types of DRL schedules, when signals were included. The present study represents a replication of procedures by Becraft et al. involving learners with autism spectrum disorder (ASD). The results replicated those of Becraft et al. in that responding in both full-session and spaced-responding DRL schedules was low, but not eliminated. These results provide preliminary evidence to suggest that children with ASD are responsive to signals in DRL arrangements, which may set the stage for evaluation of signaled DRL arrangements for socially significant response forms.     

Differential negative reinforcement of other behavior to increase compliance with wearing an anti-strip suit

Using a changing-criterion design, we replicated and extended a study (Cook, Rapp, & Schulze, 2015) on differential negative reinforcement of other behavior (DNRO). More specifically, educational assistants implemented DNRO to teach a 12-year-old boy with autism spectrum disorder to comply with wearing an anti-strip suit to prevent inappropriate fecal behavior in a school setting. The duration for which the participant wore the suit systematically increased from 2 s at the start of treatment to the entire duration of the school day at the termination of the study. Moreover, these effects were generalized to a new school with novel staff and persisted for more than a year. These findings replicate prior research on DNRO and further support the use of the intervention to increase compliance with wearing protective items, or medical devices, in practical settings.     

Further analysis of modifications to the three-step guided compliance procedure to enhance compliance among children with autism

Three-step guided compliance (vocal prompt, vocal plus model prompt, vocal prompt plus physical guidance) is a commonly used procedure to increase compliance among children with intellectual disabilities. Previous research has suggested that under some conditions, slight modifications to the three-step procedure may enhance its effectiveness. These modifications include omitting the model prompt and decreasing the interprompt interval. In the current study, we evaluated another modification to the procedure: the delivery of a high-preference item contingent upon compliance with the first vocal prompt (i.e., differential reinforcement). For 2 participants with autism, compliance remained low when we implemented differential reinforcement and the guided compliance procedure in isolation. However, compliance improved when we combined differential reinforcement and the three-step guided procedure, suggesting that for at least some children, the combination of contingent access to a high-preference item and the guided compliance procedure is more effective than either intervention alone.     

The Mediating Role of Information Search in the Relationship Between Prejudice and Voting Behavior

Evidence on the extent to which prejudice serves as a barrier to black and Latino candidates for office is mixed. Some research has found that black and Latino candidates are disadvantaged in terms of their chances of winning election and that they are evaluated differently by voters, while other findings suggest that this may not be the case. This article examines the effects of racial prejudice on candidate evaluation and voting behavior. It uses a unique experimental design to test for direct effects of prejudice on candidate evaluation and voting behavior, as well as indirect effects of prejudice on these variables via the information that subjects seek out. I find that subjects higher in symbolic racism are less likely to vote “correctly” when their preferences most closely align with a black or Latino candidate and that they rate minority candidates more negatively than their white counterparts. I also find that subjects high in prejudice search for less information about minority candidates and that this less robust information search mediates the relationship between prejudice and candidate evaluation and vote measures. Results also suggest that increased information search may mitigate the effects of prejudice on correct voting.
