Effects of public posting on driving speed in Icelandic traffic

We replicated a study by Van Houten, Nau, and Marini (1980) that had revealed reductions in vehicle speeding following the posting of percentages of drivers not speeding on a sign at roadside. Our subjects were drivers entering a residential area where the speed limit changed from 90 km/hr (55.9 mph) to 60 km/hr (37.3 mph). A total of 4,409 vehicle speeds were taken from two observation sessions per day for 20 consecutive weekdays. The intervention consisted of a single posting condition, in which a hypothetical daily percentage of drivers not speeding was posted on a feedback sign, followed by a double posting condition, in which a sign posting a best result was erected beyond the feedback sign. Results revealed a significant speed reduction from an average of 69.0 km/hr (42.9 mph) during baseline to 63.4 km/hr (39.4 mph) during single posting. Average speed during double posting was 62.9 km/hr (39.1 mph). The percentage of drivers exceeding 70 km/hr (43.5 mph) dropped from 41.0 during baseline to 20.5 during single posting. The significant speed reductions add to the generality of findings of similar studies in Canada and Israel and offer possible explanations for the failure of feedback posting to reduce speed in the U.S.     

Evaluating public posting,goal setting,and rewards to increase physical activity in children

In this study, we evaluated several components of a pedometer-based intervention with children in an elementary-school-aged classroom, across 24-h sessions. The intervention included combinations of self-monitoring, goal setting, feedback, and reinforcement, and data were analyzed at both the classroom level (i.e., average daily step totals) and the individual level (i.e., daily step totals), across phases. The highest levels of physical activity were observed when components of self-monitoring, public posting, goal setting, and feedback with reward were applied concurrently.     

Theft reduction in a grocery store through product identification and graphing of losses for employees

Shoplifting and employee theft constitute a major problem for retailers. Previous research has described techniques for effectively reducing either type of theft but has not addressed the problem of thefts of unspecified origin. In a grocery store we evaluated the effect of identifying for employees frequently stolen products from three groups of items and graphing, twice weekly in the lunchroom, losses for the separate groups. After the products were identified and losses graphed, thefts from the three groups dropped from eight per day to two per day.     

Evaluating public posting,goal setting,and rewards to increase physical activity during school recess

We evaluated a pedometer‐based intervention consisting of public posting between two teams of students, with additional self‐monitoring, goal setting, and reinforcement components, to increase physical activity during school recess. In the absence of self‐monitoring, performance feedback alone did not increase physical activity levels above those observed during baseline. Additionally, higher levels of physical activity were observed when goal‐setting was introduced, with the highest levels of activity observed when raffle tickets could be earned for exceeding a specified step‐total goal.     

Behavior analysis in consumer affairs: Retail and consumer response to publicizing food price information

A popular program among consumer action groups involves publicizing comparative food price information (CFPI) gathered from retail stores. Its significance is based on the assumption that publishing CFPI maximizes retail competition (i.e., moderates price levels or price increases) and occasions more frugal store selections among consumers. We tested these assumptions during a 2-year analysis. Specifically, we monitored the prices of two distinct market baskets in the supermarkets of two midwestern cities (target and contrast cities). Following a lengthy baseline, we published the prices of only one of the market baskets at stores in the target city in the local newspaper on five different occasions. The results suggested that reductions in price inflation occurred for both market baskets at the independently operated target stores. The corporate chain stores were not similarly affected. In addition, surveys indicated that many consumers used the CFPI as a basis for store selection. Finally, the analysis included a discussion of the politics, economics, and future of CFPI programs.     

Effects of public posting,goal setting,and oral feedback on the skills of female soccer players

We evaluated the effects of public posting, goal setting, and oral feedback on the skills of 3 female high school soccer players during practice scrimmages. The dependent variables were the percentage of appropriate responses when the player (a) kept and maintained possession of the ball, (b) moved to an open position during a game restart (e.g., goal or corner kick), and (c) moved to an open position after passing the ball. We also assessed the extent to which changes in practice performances generalized to games. A social validity questionnaire was completed by both players and coaches to assess the acceptability of the intervention's goals, procedures, and outcomes. Results indicate that the intervention was effective in improving performances during practice scrimmages but produced limited generalization to game settings.     

An analysis of a performance feedback system: the effects of timing and feedback, public posting, and praise upon academic performance and peer interaction

In the first experiment, after establishing baseline composition rates in each classroom, timing (announcing time limits) and feedback (student self-scoring) were introduced followed by the introduction, removal, and reintroduction of public posting of highest scores. Timing and feedback improved story writing performance and public posting of highest scores improved performance even further in both classrooms. Teacher praise produced further improvement in one classroom but had no effect on performance in the other. Changes in on-task behavior paralleled changes in writing rate. Comments made by children concerning their own work or work of their peers were recorded throughout the experiment. Although the baseline rate of performance comments was almost zero, the introduction of each variable markedly increased the rate of performance comments. In the second experiment, baseline rates on reading and language exercises were established in a fifth-grade classroom. The entire performance feedback system was introduced on a multiple baseline across the two behaviors and then removed during the final phase of the experiment. Introducing the system improved performance on both tasks. These results further increased the generality of some of the findings of the previous experiment and of previous research on the efficacy of the experimental package of timing, feedback, public posting, and praise.     

A diagnostic approach to increase reusable dinnerware selection in a cafeteria

The current project tested a diagnostic approach to selecting interventions to increase patron selection of reusable dinnerware in a cafeteria. An assessment survey, completed by a sample of 43 patrons, suggested that the primary causes of wasteful behavior were (a) environmental arrangement of dinnerware options and (b) competing motivational variables. A functional relation between environmental arrangement and reusable product selection was demonstrated in a reversal design. However, the largest effect occurred as function of a multicomponent intervention involving environmental arrangement, employee involvement, and personal spoken prompts with motivational signs. The results support the use of informant assessments when designing community interventions.     

Behavior analytic contributions to public health and telehealth

The Journal of Applied Behavior Analysis is launching a special series on the topics of public health and telehealth. The special series begins with the articles in this issue and will continue for the next 2 to 3 issues with an open submission window until September 1, 2020. Behavior analysis has much to offer with respect to public health and much to gain from continued and expanded use of telehealth. This paper outlines the importance of these topics in the current crisis and in our ongoing evolution as a field. The historical literature in behavior analysis is reviewed for each topic along with suggestions for future research. The articles from the special series will be combined with historical contributions from JABA into a virtual issue. We encourage continued submissions on these topics even after the special series is completed as future papers will also be incorporated into the special issue.     

Active prompting to decrease cell phone use and increase seat belt use while driving

Automobile crashes are the leading cause of death for those aged 3 to 33, with 43,005 (118 per day) Americans killed in 2002 alone. Seat belt use reduces the risk of serious injury in an accident, and refraining from using a cell phone while driving reduces the risk of an accident. Cell phone use while driving increases accident rates, and leads to 2,600 U.S. fatalities each year. An active prompting procedure was employed to increase seat belt use and decrease cell phone use among drivers exiting a university parking lot. A multiple baseline with reversal design was used to evaluate the presentation of two signs: "Please Hang Up, I Care" and "Please Buckle Up, I Care." The proportion of drivers who complied with the seat belt prompt was high and in line with previous research. The proportion of drivers who hung up their cell phones in response to the prompt was about equal to that of the seat belt prompt. A procedure that reduces cell phone use among automobile drivers is a significant contribution to the behavioral safety literature.     

Using student-managed interventions to increase homework completion and accuracy

We examined the effectiveness of self-managed individual and group contingency procedures in improving the completion and accuracy rates of daily mathematics homework assignments. A group of sixth-grade students having homework difficulties in mathematics were selected for the study. There was substantial improvement in the amount of homework completed over baseline for a majority of the students, whereas the results for accuracy were mixed. Students who participated in the self-management training made significant gains on standardized measures of academic achievement and curriculum-based measures of classroom performance. Parents also reported significantly fewer problems associated with homework completion following the intervention. Students who were allowed to select their own performance goals made superior improvements in the number of homework assignments returned compared to students who were given a specified goal by the classroom teacher. Parents, subjects, and the classroom teacher responded positively on consumer satisfaction measures following termination of the study.     

Using real-time visual feedback to improve posture at computer workstations

The purpose of the current study was to examine the effects of a multicomponent intervention that included discrimination training, real-time visual feedback, and self-monitoring on postural behavior at a computer workstation in a simulated office environment. Using a nonconcurrent multiple baseline design across 8 participants, the study assessed the effects of the intervention across three postural variables. Following an information phase, the intervention started for the lowest stable postural variable. The intervention led to substantial improvements in safety behavior for most targeted postural variables. A reversal to the information phase for 2 participants did not lead to decreases in safety. Postures self-monitored with high accuracy improved to a greater degree than postures self-monitored with low accuracy.     

Increasing senior citizen participation in a community-based nutritious meal program

Two experiments were conducted to compare the effects of several prompting and reinforcement procedures on the participation of elderly citizens in a nutritious meal program. Experiment I employed a variation of the multiple-baseline design across three groups of approximately 60 households each. Elderly persons not previously participating in the program were introduced to the following conditions: (1) public service radio announcements for four weeks to advertise the meal program and the availability of free transportation, (2) a home visit that served as a personal invitation and a second prompt for participation, (3) a followup telephone call, and (4) an incentive menu for participation, which was sent through the mail. Results indicated that the home visits and incentives were both effective as recruitment procedures and superior to other conditions; however, incentives proved to be the most cost-effective intervention. Experiment II used a variation of the multi-element design to compare the effects of scheduled activities and incentives in maintaining higher levels of participation by those persons who had attended the meal program at least once in the past, but whose current rate of participation was low. Results showed that activities improved attendance levels somewhat and that incentives substantially increased the number of meal program participants. Data from these experiments thus indicate that relatively inexpensive procedures may be used effectively to increase the extent to which elderly persons make use of potentially beneficial community-based services.     

Understanding public opinion relating to the establishment of community mental health facilities: implications of a discourse analytic approach

This paper demonstrates a novel approach to investigating the problem of public opposition to community mental health facilities. With the move towards community care, organizations setting up mental health facilities have encountered public opposition. It has been argued that this is due, in part, to the attitudes held by the public towards mentally ill people. A knowledge and understanding of attitudes towards this client group therefore has the potential to be of practical use to policy makers and practitioners who have a responsibility to consult on, and implement, community care for mentally ill people. The survey approaches and hypothetical situations used in previous British studies of community attitudes towards mentally ill people have, however, failed to take account of the rhetorical richness and complexity of the attitudes likely to be expressed in real‐life community care contexts. By contrast, the study reported in this paper used a discourse analytic approach to explore the views expressed about mentally ill people in a ‘hot situation’. Specifically, people's views were explored in the contexts of the arguments they used to challenge or advocate a supported accommodation project for mentally ill people in their community. This paper examines some of these arguments and discusses the theoretical implications for traditional approaches to attitude research. In conclusion, the potential practical utility of the findings is considered. Copyright © 1999 John Wiley & Sons, Ltd.     

Using high-probability foods to increase the acceptance of low-probability foods

Studies have evaluated a range of interventions to treat food selectivity in children with autism and related developmental disabilities. The high-probability instructional sequence is one intervention with variable results in this area. We evaluated the effectiveness of a high-probability sequence using 3 presentations of a preferred food on increasing acceptance in a child with autism who refused a few specific foods. The high-probability sequence increased acceptance of 3 foods. We then systematically faded the intervention for 2 foods.     

Using task clarification, graphic feedback, and verbal feedback to increase closing-task completion in a privately owned restaurant

An informant functional assessment was used to evaluate closing-task completion by servers and dishwashers at a restaurant. Based on the functional assessment results, an intervention consisting of task clarification, posted graphic feedback, and verbal feedback was implemented and evaluated with a multiple baseline design across two groups of employees. Results showed an increase of 15% and 38% in task completion for the two groups.     

Self-guided behavioral skills training: A public health approach to promoting nurturing care environments

The World Health Organization identified the promotion of “Nurturing Care Environments” as a global health priority. Responsive caregiving, 1 of 5 domains describing nurturing care, is critical for healthy child development. Relatively little research has evaluated population-level interventions aimed to increase responsive caregiving during the first 1,000 days of an infant's life. In this pilot study, we evaluated an intervention designed for population-level dissemination that targeted responsive caregiving. The self-guided behavioral skills training aimed to teach mothers to imitate infant vocalizations. The intervention was delivered within an on-line asynchronous training. All 3 mothers increased vocal imitative behavior following training without receiving coaching or behavior-specific feedback from an implementer. The results offer a preliminary proof of concept with implications for population-level intervention design and evaluation.     

A university-based incentive program to increase safety belt use: Toward cost-effective institutionalization

A cost-effective incentive program to increase safety belt use was implemented by the campus police of a large university. For each of the 3-week intervention periods during three consecutive academic quarters, the 22 campus police officers recorded the license plate numbers of vehicles with drivers wearing a shoulder belt. From these numbers, 10 raffle winners were drawn who received gift certificates donated by community merchants. Faculty and staff increased their belt usage markedly as a result of the "Seatbelt Sweepstakes," whereas students increased their belt use only slightly. A cost-effectiveness analysis indicated that the sweepstakes cost an average of $0.98 per each newly buckled driver. During each sweepstakes intervention, officers' belt usage increased significantly, but diminished to initial baseline levels after the final withdrawal of the program. Surveys of officers' opinions indicated that the police would accept the program demands as a regular task requirement. This result and the fact that program promotion and coordination were eventually taken over by two student organizations suggest that institutionalization of the "Seatbelt Sweepstakes" is feasible.
