Reinforcement Delay Fading During Differential Reinforcement of Communication: The Effects of Signals on Response Maintenance

Signals during delays to reinforcement may lessen reductions in responding that typically occur when there is a delay between a response and its reinforcer. Sparse applied research has been devoted to understanding the conditions under which responding may be maintained when delays to reinforcement are introduced. We evaluated the extent to which providing signals during delay fading affected responding in the context of differential reinforcement of communication responses. Three individuals were exposed to gradually increasing signaled and unsignaled reinforcement delays in multiple‐schedule and/or withdrawal designs. Results for 2 of 3 participants suggested that (a) the presence of signals facilitated response maintenance under delayed reinforcement and (b) coordinated basic and applied research may advance both conceptual understanding and clinical outcomes of delayed reinforcement.     

Further evaluation of response interruption and redirection as treatment for stereotypy

The effects of 2 forms of response interruption and redirection (RIRD)-motor RIRD and vocal RIRD-were examined with 4 boys with autism to evaluate further the effects of this intervention and its potential underlying mechanisms. In Experiment 1, the effects of motor RIRD and vocal RIRD on vocal stereotypy and appropriate vocalizations were compared for 2 participants. In Experiment 2, the effects of both RIRD procedures on both vocal and motor stereotypy and appropriate vocalizations were compared with 2 additional participants. Results suggested that RIRD was effective regardless of the procedural variation or topography of stereotypy and that vocal RIRD functioned as a punisher. This mechanism was further explored with 1 participant by manipulating the schedule of RIRD in Experiment 3. Results were consistent with the punishment interpretation.     

Association of Depression with Complications of Diabetic Pregnancy: A Retrospective Analysis

The goal of this study was to determine whether an association between histories of depression and adverse pregnancy outcome could be established using a retrospective analysis. Participants were a convenience sample of 152 pregnant diabetic women for whom prior pregnancy data were available. Prior pregnancy outcome, depression history, and other clinical characteristics were determined from chart review and medical history questionnaires. Logistic regression was used to determine which of the measured clinical factors, including history of depression, had a significant association with history of pregnancy complications. Thirty-nine patients (26%) had a past history of depression. Three pregnancy complications (preterm labor, pre-eclampsia, fetal prematurity) were more common in the group having a history of depression as was the proportion of participants requiring Caesarean section p( < .05 for each comparison). A history of depression was associated with prior pregnancy complications independent of the effects of parity, prepregnancy BMI, tobacco use history, diabetes type, and presence of diabetes complications (OR = 3.6; 95% CI = 1.5–9.0, p = .006). These retrospective data indicate that depression is linked to complications of diabetic pregnancy and support the need for prospective studies to clarify the effects of depression and its treatment on diabetic pregnancy.     

Assessing and teaching job‐related social skills to adults with autism spectrum disorder

Few studies have evaluated interventions to improve the job‐related social skills of adults with autism spectrum disorder. In this study, we examined the efficacy of a treatment package for teaching several social skills that are critical to job success, such as responding appropriately to feedback and asking for a task model from the supervisor. Three adults, aged 19 to 27 years, participated. Initial training of each skill consisted of verbal explanations, modeling, and role‐play with feedback, along with stimulus prompts to promote generalization to a different setting. The trainer introduced additional intervention components as needed. We also evaluated generalization across different social skills and evocative situations. Results indicated that the treatment package was generally effective in improving the targeted social skills, and that stimulus prompts may be necessary for generalization to a job setting. However, generalized responding across social skills rarely emerged. These findings have important implications for preparing individuals with autism to function successfully on the job.     

Effectiveness and acceptability of parent training via telehealth among families around the world

Teaching parents to conduct functional analyses and to implement functional communication training is an efficacious approach for treating socially maintained problem behavior (Derby et al., 1997). Research has found that delivering this assessment and intervention package via telehealth technologies is efficient and acceptable to caregivers in the United States (Wacker et al., 2013b). We replicated this work with families residing in rural and urban areas of eight countries. Two behavior therapists located in the United States conducted appointments in the participants' native languages, using interpreters as needed. Parent‐implemented functional analyses and treatment with functional communication training were highly effective in reducing problem behavior in children diagnosed with autism. Furthermore, parents rated the procedures as acceptable and indicated that the treatment would be effective with their children. These findings indicate that telehealth technologies are a viable option for clinicians to provide behavior analysis services to families around the world.     

Comparing continuous and dichotomous scoring of the balanced inventory of desirable responding

The Balanced Inventory of Desirable Responding (BIDR; Paulhus, 1994) is a widely used instrument to measure the 2 components of social desirability: self-deceptive enhancement and impression management. With respect to scoring of the BIDR, Paulhus (1994) authorized 2 methods, namely continuous scoring (all answers on the continuous answer scale are counted) and dichotomous scoring (only extreme answers are counted). In this article, we report 3 studies with student samples, and continuous and dichotomous scoring of BIDR subscales are compared with respect to reliability, convergent validity, sensitivity to instructional variations, and correlations with personality. Across studies, the scores from continuous scoring (continuous scores) showed higher Cronbach's alphas than those from dichotomous scoring (dichotomous scores). Moreover, continuous scores showed higher convergent correlations with other measures of social desirability and more consistent effects with self-presentation instructions (fake-good vs. fake-bad instructions). Finally, continuous self-deceptive enhancement scores showed higher correlations with those traits of the Five-factor model for which substantial correlations were expected (i.e., Neuroticism, Extraversion, and Conscientiousness). Consequently, these findings indicate that continuous scoring may be preferable to dichotomous scoring when assessing socially desirable responding with the BIDR.     

A cross-linguistic data bank for oral picture naming in Dutch, English, German, French, Italian, Russian, Spanish, and Swedish (PEDOI)

The well established effect of word frequency on adult's picture naming performance is now called into question. This is particularly true for variables which are correlated with frequency, as is the case of age of word acquisition. Since the work of [Carrol and White, 1973] there is growing agreement among researchers to confer an important role in lexical access to this variable. Indeed, it has been shown ( [Hodgson and Ellis, 1998]) that for normal English-speaking adults only the variables 'age-of-acquisition' and 'name agreement' are independent predictors of naming success among the various variables considered. However, when brain-damaged subjects with and without degenerative pathologies are studied, word frequency and word length as well as concept familiarity all give significant effects ( [Hirsh and Funnell, 1995]; [Lambon Ralph et al., 1998]; [Nickels and Howard, 1995]). Finally, it has been suggested that the production of specific error types may be related to such variables. According to [Nickels and Howard, 1994] the production of semantic errors is specifically affected by 'imageability' and in the recent study by [Kremin et al., 2001] 'age of acquisition' predicts (frank) word finding difficulties.
