Comparing computer‐based training and lecture formats to teach visual analysis of baseline‐treatment graphs

Accurate analysis of data is vital to the validation of interventions. As such, there has been a recent increase in studies evaluating visual analysis training procedures. However, past investigations have not evaluated direct and indirect visual analysis training methods with matched instructional content that was systematically designed. Furthermore, training has rarely included assessment of generalization and maintenance of visual analysis skills. The purpose of the current dissertation study was to compare the effectiveness and efficiency of (a) computer‐based training, (b) lecture formats with and (c) without the opportunity to pause, and (d) a no‐training group to teach visual analysis of AB graphs to university students. To make these formats directly comparable, the instructional content was equated by ensuring information and examples were identical across the three training procedures. Eighty‐three students were randomly assigned to one of the four groups. Results showed that all three training formats produced increases in accurate responding compared to the no‐training group. Visual analysis skills generalized to novel graphs and maintained approximately 2 weeks following all trainings. These results suggest that structured approaches that are carefully designed to train visual analysis are effective and lead to gains that generalize and maintain in the absence of training.     

On-road study investigating the mode of feedback delivery on young drivers’ speed management

Feedback has been shown to be instrumental in learning. Refining how it is delivered in driver training has the potential to reduce crash risk. Therefore, the aim of the present study was to examine the effect of the medium in which feedback is delivered (verbal, written, graphical) on young drivers’ speed management behaviour. Sixty young drivers, randomly allocated to one of four feedback groups (i.e., Control, Verbal feedback, Written feedback, and Graphical feedback) completed one training and two test drives using an instrumented vehicle on-road. After the first (baseline) drive, participants were provided feedback about the number of times they exceeded the speed limit, their maximum speed, as well as the financial penalties associated with such driving behaviour, and safety implications. The content of feedback remained the same for all training groups, except for the manner in which the feedback was presented. Verbal feedback was provided verbally by the researcher; written feedback on paper; and graphical feedback using a series of graphs on a computer screen. Control received no such intervention. Two test drives followed, one immediate post-training, and the second one week post-training. Feedback, irrespective of medium improved young drivers’ speed management. Verbal and graphical feedback yielded the greatest reduction in speeding behaviour, with graphical feedback having the most impact in the two speed zones under examination (50 km/h & 80 km/h). Control showed the poorest speed management behaviour in all drives. These findings have important implications for the development of a new approach to improve young drivers’ speed management behaviour.     

The effects of statistical training on choice heuristics in choice under uncertainty

Kahneman and Tversky (1984) proposed that decision makers perceive choice uncertainty in two ways: (1) as a distribution of possible outcomes or (2) as a single uncertain outcome. Using statistical training as a factor that influences these perceptions, and thus the type of decision approach individuals use, we found that individuals with different levels of experience displayed differences in the decisions they made and in the choice heuristics used to make those decisions. Statistically naive individuals were more likely to prefer loss-minimizing alternatives, use a more non-compensatory heuristic, and spend more time on loss-related information than their statistically experienced counterparts. When a distributional cue, indicating the distributional nature of choice outcomes, was presented to both experience groups, the naive group was found to use a decision approach similar to the experienced group and to make similar decisions. The results are discussed in terms of the need to include factors that alter individuals' approaches to uncertainty in future behavioral models of uncertain choice.     

A comparison of skill-building and desensitization strategies for intervention with aggressive children

Social skills training and desensitization interventions were conducted with 41 institutionalized aggressive children aged 7–13. Subjects were randomly assigned after blocking by aggression and cooperative play to either of the treatments. Dependent measures were direct observations of playground play and teacher ratings. Subjects in the social skills program mastered the basic cognitive skills presented to them. Observational data indicated that both groups experienced marked reduction in aggressive behavior and increases in cooperative play. The social skills training intervention engendered incremental improvement in aggression in comparison to the desensitization condition. However, none of the behavioral changes evident in the observations were reflected in teacher ratings.     

The Role of Professional Training Experiences and Manualized Programs in ABA Providers’ Use of Parent Training With Children With Autism

Parent training, in which providers teach parents intervention strategies to promote their children’s skill acquisition and/or behavior management, is considered a best practice in the treatment for children with autism spectrum disorder (ASD) and yet is underutilized in community settings. The present study examined the role of training experiences and manual use in promoting the use of parent training by community providers who serve children with ASD. Applied behavior analysis (ABA) providers (N = 1,089) from across the United States completed self-report questionnaires online. The total number of professional training experiences related to parent training significantly predicted the extensiveness of providers’ use of parent training. Receiving supervision in parent training, being trained in a specific parent training approach, taking a course related to parent training, and participating in self-guided learning (e.g., webinar) were unique predictors of parent training extensiveness. While only 15% of ABA providers used manualized parent training programs, using a manual was also a unique predictor of parent training extensiveness. Parallel multiple mediator analyses demonstrated that family-, provider-, and organization-level barriers all partially mediated the relationship between number of training experiences and parent training extensiveness; only provider- and organization-level barriers mediated the relationship between manual use and parent training extensiveness. Recommendations for training and supporting providers at the pre-service and in-service levels are discussed as a means of increasing access to parent training for children with ASD in community settings.     

Teaching caregivers to implement mand training using speech generating devices

Individuals with developmental disabilities often do not develop vocal repertoires, thus requiring the use of augmentative devices. Teaching caregivers to conduct communication training with their children may be one way to foster communication with their device in the natural environment. This study replicates Rosales, Stone and Rehfeldt (2009), but using an augmentative device. Behavioral skills training was used to teach caregivers to implement mand training procedures. Caregivers quickly learned to implement mand training with their children and independent mands increased from pretraining to posttraining observations for 2 out of 3 children.
