Previous research has shown that contingent vocal imitation has a reinforcing effect on vocalizations emitted by children. Nevertheless, the precise contingencies that have a reinforcing effect on vocalizations remain unclear. This study examined the effects of five conditions (contingent vocal imitation, contingent interaction, noncontingent…

Error correction procedures are remedial strategies presented following an incorrect response that increases the probability that a correct response will occur in the future. Error correction is commonly used during skill acquisition programs for children with developmental disabilities; however, the specific strategy used may differ considerably.…

Prior research has examined interventions to prevent prompt dependence from occurring during the training of novel skills. Nevertheless, the relative efficacy and efficiency of different intervention procedures may be idiosyncratic across learners, suggesting the potential benefit of an individualized assessment. The purpose of the current study…

Teaching job-related problem-solving skills may increase the likelihood that individuals with developmental disabilities obtain and maintain employment (Kaye et al., 2011; Peck & Kirkbride, 2001; Unger, 2002). In this study, we evaluated the use of electronic-based flowcharts on an iPod Touch as a form of self-instruction to increase problem…

The benefits of permanent pictorial prompts in enhancing maintenance and generalization are likely dependent on their degree of stimulus control and the extent to which their use is generalized. Although several studies on the use of pictorial prompts have demonstrated their efficacy (e.g., Pierce & Schreibman, 1994; Wacker & Berg, 1983; Wacker,…

Five individuals with autism or other developmental disabilities participated in paired-stimulus preference assessments during repeated baseline probes. All subjects initially showed a pronounced bias by typically selecting the stimulus placed in either the left or right position. Biased responding for 3 subjects was eliminated when training…

Preference assessments directly evaluate items that may serve as reinforcers, and their implementation is an important skill for individuals who work with children. This study examined the effectiveness of pyramidal training on teachers' implementation of preference assessments. During Experiment 1, 3 special education teachers taught 6 trainees…

Three adult male sex offenders with developmental disabilities participated in phallometric assessments that involved repeated measures of arousal when exposed to various stimuli. Arousal assessment outcomes were similar to those obtained by Reyes et al. (2006). Additional data-analysis methods provided further information about sexual…

We evaluated the effects of feedback and instruction on resident physician performance during developmental surveillance of infants at 2-month preventive care visits. Baseline data were obtained by videotaping 3 residents while they performed the physical and developmental exam components. Training consisted of individualized feedback and a brief…

Although the use of differential reinforcement has been recommended in previous investigations and in early intervention curriculum manuals, few studies have evaluated the best method for providing differential reinforcement to maximize independent responding. This paper reviews previous research on the effectiveness of differential reinforcement…

Stereotypical behavior maintained by automatic reinforcement often does not result in harm but may be undesirable in some situations. In the current investigation, participants were 2 individuals who engaged in nonharmful stereotypical responses shown in an analogue functional analysis to be insensitive to social contingencies. After bringing…

When responses function to produce the same reinforcer, a response class exists. Researchers have examined response classes in applied settings; however, the challenges associated with conducting applied research on response class development have recently necessitated the development of an analogue response class model. To date, little research…

We examined the effects of individualized video modeling on the accurate implementation of behavioral interventions using a multiple baseline design across 3 teachers. During video modeling, treatment integrity improved above baseline levels; however, teacher performance remained variable. The addition of verbal performance feedback increased…

Research has not systematically assessed and validated preferences for staff in adults with developmental disabilities. Three adults with developmental disabilities (aged 32 to 43 years) identified preferred and nonpreferred staff using verbal and pictorial preference assessments. During break-point analyses with progressive-ratio schedules, all 3…

The current study examined whether stimuli of different preference levels would be associated with different amounts of work maintained by the stimuli, as determined through progressive-ratio schedule break points. Using a paired-choice preference assessment, stimuli were classified as high, moderate, or low preference for 4 individuals with…
