EVALUATION OF A COMMERCIALLY AVAILABLE PROGRAM AND IN SITU TRAINING BY PARENTS TO TEACH ABDUCTION‐PREVENTION SKILLS TO CHILDREN

Child abduction is a serious problem; therefore, it is essential that researchers evaluate the efficacy of commercially available abduction‐prevention programs. A multiple baseline design across participants (ages 6 to 8 years) was used to evaluate the effects of a training program, The Safe Side. Experimenters assessed safety responses in situ in two different situations (knock on the door and interaction by a stranger in public). Results revealed that participants did not demonstrate the safety skills following Safe Side training. All participants subsequently received in situ training (IST) implemented by the parent. Additional assessments and IST were conducted until each participant performed the skills to criterion. All participants demonstrated criterion performance following IST and maintained the skills over time.     

Evaluating the Effectiveness of an Abduction Prevention Program for Young Adults With Intellectual Disabilities

The purpose of this study was to evaluate the effectiveness of behavioral skills training (BST) and in situ training (IST) for teaching abduction prevention skills to young adults with intellectual disabilities. Four individuals, ages 18–24, participated. Five BST sessions were conducted for each participant. Following BST, in situ assessments took place at the participants’ school to assess acquisition of the skills. The data show that none of the participants reached criterion level following BST although some of the participants improved their score from baseline. IST was then implemented with two of the participants achieving criterion level and two participants exhibiting two of the three safety skills.     

Assessing long‐term maintenance of staff performance following behavior skills training in a home‐based setting

We used a multiple baseline across participant design to evaluate the effects of behavior skills training on teaching three behavior therapists to implement discrete trial teaching (DTT) and evaluate the long‐term maintenance of skills acquired through behavioral skills training. For participants whose skills did not maintain, the authors evaluated an independent self‐evaluation procedure on their performance. Following DTT implementation training, maintenance probes were assessed at 2‐, 4‐, 6‐, and 8‐week follow‐ups. The results demonstrated that one participant maintained 100% procedural integrity (PI) through all follow‐ups, one participant decreased below mastery criterion at the 2‐week follow‐up, and one participant dropped below mastery criterion at the 4‐week follow‐up. Those participants that demonstrated decreased accuracy of implementation of DTT programs and were taught to implement a self‐evaluation procedure. Following self‐evaluation, PI maintained for up to 7 weeks for one participant. Our results suggest that if PI does not maintain, self‐evaluation may be a supplementary intervention to increase and maintain PI of new employees.     

Evaluating small‐scale simulation for training firearm safety skills

There is limited research using small‐scale simulation in applied behavior analysis. We used small‐scale simulation to train firearm safety skills to 3‐ to 5‐year‐old children and assessed whether the skills generalized to the natural environment through in situ assessment. Three participants completed the training, and all participants learned the safety skills from simulation training. Two of the participants acquired the safety skills after the first simulation training, and the third participant required one booster training before demonstrating the safety skills in the natural environment.     

Preliminary evaluation of a parent training program to prevent gun play

Recent research has shown that behavioral skills training with in situ training is an effective strategy to teach children the safety skills needed if they ever encounter an unattended firearm. The current study evaluated the use of parents as trainers to increase the efficiency of training. The success of parent training on their children's safety skills was evaluated in a multiple baseline across participants design. The results showed that the training was effective for 3 of the 4 children.     

Mini‐breaks: the use of escape on a fixed‐time schedule to reduce unauthorized breaks from vocational training sites for individuals with brain injury

This study evaluated mini‐breaks with three individuals who were traumatically brain injured and engaged in unauthorized breaks. The vocational instructors reported that the three participants were having problems staying at their scheduled vocational training sites (walking away without permission). Following baseline, participants were placed on mini‐breaks; that is, participants were given a ten‐minute mini‐break every hour. Thus, mini‐breaks were given without regard to unauthorized breaks. Unauthorized breaks decreased to zero levels for all three participants when mini‐breaks commenced. Following 1 month of the mini‐breaks, two of the participants were put back on a regular break schedule (one 15‐minute AM break and one 15‐minute PM break and a 30‐minute lunch break). The third participant was placed in supported work. The effects of the mini‐breaks were maintained. Copyright © 1999 John Wiley & Sons, Ltd.     

Peer-mediated social-skills training and generalization in group homes

A multiple baseline across subjects design was used to evaluate generalization effects of a peer-tutoring procedure to teach social skills for individuals with developmental disabilities. Three residents with poor social skills living in community-based group homes served as participants in this study. Generalization data were collected during four conditions: (i) baseline (ii) social-skills training by therapist (iii) social-skills training by peer-tutor, and (iv) follow-up. Results demonstrated that participants did not generalize trained social skills to untrained settings (i.e., living room of a group home and community bowling alley) until the first participant was trained as a peer-tutor to train two other participants. These results were maintained 6 months after training was withdrawn. © 1998 John Wiley & Sons, Ltd.     

Derived Rule Tacting and Subsequent Following by Slot Machine Players

During a slot machine gambling task, six adult participants wagered red or silver coins, which had no impact on the programmed contingencies of the game. Following baseline gambling, each participant was presented with a series of conditional discrimination training and testing trials to establish a self-rule that either the red or silver coins were somehow “better” to use. Tacting of the participant’s self-rule was measured using fill-in-the blank and multiple-choice procedures. Upon returning to slot machine gambling, five of six participants altered their response options among coin colors in accordance with newly derived self-rule. Implications for conceptual development of self-awareness and practical applications of self-awareness using Skinner’s framework of language are discussed.

     

THE EFFECTS OF BEHAVIORAL SKILLS TRAINING ON IMPLEMENTATION OF THE PICTURE EXCHANGE COMMUNICATION SYSTEM

The effectiveness of a behavioral skills training (BST) package to teach the implementation of the first three phases of the picture exchange communication system (PECS) was evaluated with 3 adults who had no history teaching any functional communication system. A multiple baseline design across participants was used to evaluate the effectiveness of the training package, which consisted of a video, written and verbal instructions, modeling, rehearsal, and feedback. Results showed significant improvements relative to baseline in a short amount of training time and that skills generalized to a learner with a severe developmental disability. Skills were maintained at 1 month follow‐up for 1 participant.     

老年人加工速度的干预研究

对老年人加工速度进行干预, 旨在考察加工速度在老年期的可塑性。首先对46名60~79岁城市社区老年人实施前测, 包括两项加工速度测验(数字比较、图形匹配)、成套基本心理能力测验和老年人日常智力自我效能感问卷。然后, 干预组25名老年人接受每周一期(每期50min)共计5期的加工速度训练。训练内容为图形模式比较。所有被试在训练周期结束后接受后测, 并在后测结束4个月后接受追踪测验。结果表明, 能够通过加工速度干预显著提高老年人图形匹配测验成绩, 并对词汇流畅测验成绩有迁移作用, 但干预和迁移效果并未保持到4个月。与数字比较测验相比, 图形匹配测验能够更稳定地反映干预的效果。     

Antecedent Selection: Comparing Simplified and Typical Verbal Antecedents for Children with Autism

This study measured the differential effects of simplified and typical verbal antecedents on acquisition of picture discriminations for four preschool children with autism. During baseline probes, participants emitted no correct selection responses to pictures of common stimuli during either simplified or typical verbal antecedent conditions. Using an adapted alternating treatments design during training, instructors presented a simplified verbal antecedent (i.e., “Give me car”) or a typical verbal antecedent (i.e., “One of these is a car. Which one is it?”), and differentially reinforced participants’ correct selection responses given the target picture and two non-targets. Results showed that one participant emitted more correct responses during simplified than typical verbal antecedent conditions, one participant emitted more correct responses during typical than simple verbal antecedent conditions, and there was no clear difference for the other two participants.     

Exchange‐based communication training may not consistently facilitate communication in the absence of the requested item

The role of stimulus presence on spontaneous communication was assessed with 3 participants in a nonconcurrent multiple baseline with embedded reversals design. Participants were taught to request 2 highly preferred items. Once mastery criterion was met, test sessions were conducted with stimuli either visible or absent from the room, and request rate was measured. For 2 participants, training produced requests in both the presence and absence of the stimulus. For one participant, however, the presence of the stimulus was necessary to evoke the response. Results suggest that teaching individuals to request items when they are present may not consistently lead to requests when those items are absent.     

Community-based instruction for independent meal preparation by adults with profound mental retardation

Three adults with profound mental retardation and very limited reading skills were transitioned to community living after spending more than 20 years in a residential facility. Community-based instruction was used to teach them to independently prepare meals. Directed rehearsal and prompting procedures were used to teach them those meal preparation skills that they were unable to perform independently. We present assessment, training and followup data on the preparation of a dessert by the three participants. Following an assessment on the steps needed to prepare the dessert, training was introduced in a multiple baseline across subjects design. Results showed that the participants were able to independently prepare the dessert in up to 21 pre-training and training sessions. Monthly followup for six months showed that they were able to independently prepare the dessert in various community settings of their choice.     

PREVENTING BACK INJURIES IN HOSPITAL SETTINGS: THE EFFECTS OF VIDEO MODELING ON SAFE PATIENT LIFTING BY NURSES

This study evaluated video scoring and feedback about scoring as a safety intervention among 6 nursing staff. The dependent variable was safety behavior on one‐person transfers. Following baseline, 5 nursing staff participated in an information phase. A video scoring phase was then introduced for all 6. A feedback phase was added for 2 participants. All participants experienced treatment withdrawal. Information resulted in improvements for all 5 participants who received it. Further improvements were observed during video scoring for the 5 participants who improved following information. No improvements were observed for the participant who received only video scoring. Safety feedback further improved safety for the 2 participants who received it. However, participants' behavior returned to video scoring levels during withdrawal.     

Teaching Spelling Through Prompting and Review Procedures Using Computer-Based Instruction

Computer-based instruction (CBI) was used to teach 3 sets of 20 spelling words to two 6th graders in a multiple baseline design. The CBI presented a voice recording of each spelling word and prompted the students to type the word. If they spelled the word incorrectly, a training procedure was initiated that included prompt fading and systematic review practice. Results showed that three to ten 15-min training sessions were needed for participants to score 100% on each word set. During a subsequent maintenance phase, one participant received 2 re-training sessions on word Set 2 due to low performance but no other training was provided. Average performance was 93% across all word sets during the final three sessions of the maintenance phase and 79% on a 3-week follow-up test. Kristin H.

The effects of conducting behavioral observations on the behavior of the observer

Behavior-analytic approaches to occupational safety are often effective for improving safety in organizations, and have been successful in a wide variety of settings. The effects of these safety processes are thought to arise primarily from the behavioral observation process and the delivery of feedback. Typically, supervisors or employee observers involved in behavioral safety implementations conduct observations. The present study was an attempt to assess the effects of conducting observations on an observer's safety performance. An ABC multiple baseline counterbalanced across two sets of behaviors was conducted in a simulated office. The target behaviors involved knee and back positions during lifts; back, shoulder, and feet positions while sitting; neck and wrist positions while typing; and neck position during phone use. Substantial improvements in safety performance occurred after participants conducted observations on a videotape of a confederate's performance. The possible behavioral functions responsible for this change, and the implications of these findings for applied settings, are discussed.     

Enhancing the training integrity of human service staff using pyramidal behavioral skills training

This experiment used a pyramidal training model to evaluate the effects of behavioral skills training (BST), delivered in a 1-time group-training format, on the extent to which 25 human service staff implemented BST when training others how to implement behavioral procedures. Results indicated that (a) the training workshop increased BST integrity to mastery levels for the majority of participants with varying levels of education, organizational positions, and training experience, (b) the training effects generalized to teaching an untrained skill, and (c) high levels of BST integrity maintained at follow-up 4 to 6 weeks after training for all 3 participants with whom probes were conducted. Moreover, participants indicated high levels of satisfaction with both the training workshop and BST as a training procedure.     

Driving and gaze behavior while texting when the smartphone is placed in a mount: A simulator study

The aim of this study was to investigate how texting when the smartphone in a mount next to the wheel, negatively affects safe driving behavior and gaze behavior. In most countries hand-held phone use while driving is prohibited. However, when texting is not explicitly forbidden and only hand-held use is not allowed, drivers can still legally operate their smartphone with their fingers when it is placed in a mount which is attached to the dashboard or the windscreen. The effects on driving and gaze behavior of ‘dashboard-mount’ texting have hardly been investigated. Twenty-seven participants drove three short identical drives in a simulator while their driving behavior and gaze behavior was measured. This was a drive in which participants did not text (baseline drive), a drive while they texted with a smartphone in one hand (hand-held drive), and a drive in which they texted while the phone was placed in a dashboard-mount (dashboard-mount drive). Participants looked significantly more often at the smartphone during the dashboard-mount than during the hand-held drive. Total dwell time at the smartphone was significantly longer during the dashboard-mount than during the hand-held drive. There were no significant differences between the two texting drives in the number of glances longer than 2 s, the longest glance of each participant, and mean fixation duration at the smartphone. Total dwell time in the mirrors was significantly shorter during the two texting drives than in the baseline drive but did not differ between the two texting drives. The drivers showed poorer lateral control and varied their speed more in the two texting drives than in the baseline drive. They also drove significantly slower in the two texting drives than in the baseline drive. Finally, subjective workload was much higher in the two texting drives than in the baseline drive. The results indicate that dashboard-mount texting deteriorates the safe execution of the driving task to at least the same extend as hand-held texting does.     

USING STIMULUS EQUIVALENCE PROCEDURES TO TEACH NAME-FACE MATCHING TO ADULTS WITH BRAIN INJURIES

On pretests, 3 men with brain injuries matched dictated names of three therapists to written names, but did not match dictated or written names to photos, produce correct names in response to photos, locate offices given written names, or name therapists on sight. Match-to-sample training established conditional relations between dictated names and photos. Posttests showed the emergence of untrained conditional relations involving photos and written names, indicating development of three classes of equivalent stimuli (each containing a dictated name, photo, and written name). For 1 participant, conditional relations involving photos of office nameplates were also examined, but did not emerge pre- or posttraining. Two participants produced names orally when given photos and sorted written names and faces together after training; the 3rd participant was unavailable for these posttests. After training, 1 participant located and named all three therapists in their offices.
