Increasing following headway with prompts, goal setting, and feedback in a driving simulator

We evaluated the effects of prompting, goal setting, and feedback on following headway of young drivers in a simulated driving environment and assessed whether changes produced in following headway were associated with reductions in hard braking when drivers were and were not using cell phones. Participants were 4 university students. During baseline, drivers spent half of the time talking on cell phones while driving. At the start of the intervention, drivers were prompted to increase following headway while on the cell phones and were provided a specific target for following headway. Drivers were given feedback on increasing following headway when on cell phones at the end of each session. The intervention package was associated with an increase in following headway and a decrease in hard braking when participants were on and off the cell phones. Cell phone use did not affect any of the measures.     

An evaluation of textual prompts and generalized textual instruction‐following

The benefit of permanent prompts depends on the extent to which their use is generalized. Previous research has demonstrated both control by and efficacy of pictorial prompts (e.g., Phillips & Vollmer, 2012). The present studies similarly evaluated stimulus control by textual prompts. Six school aged children with intellectual disabilities were taught to complete four 5‐step instructional sets under the control of textual prompts. All 6 subjects showed some generalization to the final set. The results suggest that training served 1 of 3 purposes: (a) established control by the textual prompts or the ordinal sequence thereof, (b) addressed a reading deficit, or (c) addressed the lack of a motivating operation during baseline. Training a single task sequence may not be sufficient for acquisition of generalized textual instruction‐following. However, establishing appropriate stimulus control by the textual prompts may facilitate acquisition of a generalized repertoire.     

Age-related changes in task-switching components: the role of task uncertainty

The present study examined age differences in executive functioning, using an externally cued task-switching paradigm. Two components of task switching were assessed: the ability to maintain and select among task sets (general switch costs) and the ability to switch between task sets (specific switch costs). In contrast to previous findings, we found large age-related differences in specific switch costs, especially when the number of potentially relevant task sets is increased from two to four. Age-related differences in general switch costs were absent when external task cues subserved executive processing in task switching. Generally, the findings suggest that age-related impairments in task-switching components vary as a function of task uncertainty, such as the presence of environmental prompts to behavior.     

The impact of verbal prompts on child safety-belt use in shopping carts

Each year thousands of children are injured by falling from shopping carts. Buckling children into the seats of shopping carts could prevent many of these injuries. A combined reversal and multiple baseline across settings design was used to evaluate the impact of verbal prompts on shopping cart safety-belt use in two stores. Safety-belt use increased following implementation of the verbal prompt. This study extends the literature on the efficacy of verbal prompting in the promotion of safety-belt use.     

Comparing the effects of echoic prompts and echoic prompts plus modeled prompts on intraverbal behavior

We compared strategies to teach vocal intraverbal responses to an adolescent diagnosed with autism and Down syndrome. One strategy involved echoic prompts only. The second strategy involved an echoic prompt paired with a modeled prompt in the form of sign language. Presenting the modeled prompt with the echoic prompt resulted in faster acquisition of correct responding. Results are discussed in terms of using functional stimulus classes to facilitate vocal intraverbal acquisition with learners who have a history of sign language training.     

An analysis of a contingency program on designated drivers at a college bar

The present study evaluated the effects of prompts and incentives on designated drivers in a bar. We defined the dependent variable as the percentage of customers either functioning as or riding with a designated driver. We used an ABCA design to evaluate the effectiveness of prompts and incentives on the dependent variable. Results indicated that the intervention was successful at increasing the ratio of safe to unsafe passengers in a bar.     

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.     

Effects of a checklist on self-assessment of blood glucose level by a memory-impaired woman with diabetes mellitus

This study evaluated effects of a checklist on the accuracy of self-assessment of blood glucose level by a diabetic woman with memory impairments caused by viral encephalitis. The checklist consisted of 54 steps for operating an electronic glucometer, which the subject performed in sequence and checked off when completed. Following introduction of the checklist, the percentage of steps completed correctly increased in simulated and actual blood glucose tests and yielded clinically useful information.     

Using concurrent reinforcement schedules and prompts to produce varied manding: A replication of Seaver and Bourret (2020)

Deficits in social communication and restricted, repetitive patterns of behavior or interests are displayed by individuals with autism spectrum disorder (ASD; American Psychiatric Association, 2013). Given this, individuals with ASD may engage with a limited variety of reinforcers. Treatments designed to modify the distribution of manding may allow individuals to contact a broad array of reinforcers that could improve the quality of life for individuals with ASD (Seaver & Bourret, 2020). The purpose of the current study was to replicate the results of Seaver and Bourret (2020) by evaluating the effects of manipulating concurrent schedules of reinforcement, alone and with prompts, on the rates of target manding in three boys with ASD, aged 7–9 years, in the United Arab Emirates. All three participants showed increased target manding following intervention. The findings support the use of concurrent reinforcement schedules and prompts as an effective intervention to produce varied manding.     

INCREASING ENGAGEMENT IN DAILY ACTIVITIES BY OLDER ADULTS WITH DEMENTIA

This study analyzed the effects of nursing assistants' use of prompts and praise to increase the engagement of older adults with dementia in daily living activities. The multiple baseline design across morning and afternoon work shifts showed consistent increases in engagement by each of the 5 residents during the intervention. These results suggest that increasing prompts and praise by nursing assistants may, in turn, increase the rate of engagement of older adults with dementia.
