SOME ETHICAL CONSIDERATIONS OF SHORT-TERM WORKSHOPS IN THE PRINCIPLES AND METHODS OF BEHAVIOR MODIFICATION1

Workshops and seminars to expose different sectors of the professional community to the principles and applications of behavior modification are briefly discussed. The possible misapplication of procedures by conference participants, whose only exposure to behavioral methods has been at these workshops is viewed as a potentially serious ethical issue. It is suggested that the goals of such seminars and workshops must be clarified, and methods of evaluation of the participants' skills devised, lest we contribute to the misapplication of procedures and to the criticism that behavioral methods are unethical approaches to treatment.     

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.     

OPERANT PROCEDURES AND THE COMATOSE PATIENT

Operant procedures were tested on three patients who had been in vegetative coma for 6 months, 10 months, and 38 months. A discrete trial procedure was used to test compliance to verbal requests for three behaviors for each patient, including lateral head movement or finger movement, eye focus or eye squeeze, and mouth movement. The design for each patient consisted of multiple baselines across three behaviors with a withdrawal phase and a reinstatement phase (ABAB) for one behavior. Baseline phases were followed by contingent music phases in which 15-second taped excerpts of patients' preferred music sounded immediately following the emission of targeted behaviors. The contingent music treatment affected all three behaviors for Patient 1, but was less effective for two out of three behaviors for the second and third patients who had been in coma for more extensive periods of time. Results are discussed in terms of the potential contributions of the use of operant assessment and treatment procedures in an area of medicine where they have not been used before.     

Utilization analysis of a pedestrian safety training program

A previously developed and analyzed pedestrian safety training program was used to teach appropriate street-crossing behaviors to kindergarteners and first graders. Adult crossing guards were trained to provide pedestrian safety instruction. Trained observers monitored the quality of instructions given by crossing guards and the pedestrian behavior of young children as they crossed the street. A multiple-baseline analysis of the effects of two training programs indicated that guards were able to deliver the pedestrian safety program to several groups of children with a high degree of competence after receiving a single videotape and role playing training session. Furthermore, children's level of appropriate street crossing increased contemporaneous to the change in guard behavior both on the street where training was delivered and on a second street where no training was previously delivered. Utilization analysis of the guard training program indicated that one cannot expect to produce consistently high levels of street-crossing behavior by implementing only the "show and tell" portions of the training package. Similarly, results suggested that one is unlikely to produce consistently high quality guard training behavior by only giving written instructions describing how pedestrian training should be administered.     

Pedestrian jaywalking under facilitating and nonfacilitating conditions

Each year, thousands of pedestrians are killed or injured while crossing streets in the United States. Pedestrians who jaywalk across busy intersections increase their risk of being injured by an automobile. The present series of studies investigated pedestrian jaywalking behaviors under temporal conditions which appeared to control noncompliance and compliance with pedestrian walk signs. An intersection involving three major streets was the target site of the studies. The timing of walk and no-walk light sequences was different in the clockwise and counterclockwise direction and produced differential delays. In three separate studies, significantly more pedestrians jaywalked when walking in the long-delay as opposed to short-delay direction. Traffic planners might use these findings to establish safer pedestrian signal systems.     

ASSESSMENT AND TRAINING OF CLINICAL INTERVIEWING SKILLS: ANALOGUE ANALYSIS AND FIELD REPLICATION

Two studies were conducted to assess and train clinical interviewing skills. In Experiment 1, eight university practicum students (“therapists”) and either role played or volunteer “clients” were audiotaped during simulated interviews. Following the collection of baseline data on both therapist and client responses, training was provided by way of written materials, classroom instruction and practice, and quizzes. Results of a multiple baseline design across subjects showed improvements in therapists' interviewing skills and subsequent increases in client responding. Experiment 2 replicated and extended the research to a hospital outpatient clinic, in which therapists interviewed the parents of children with behavior problems. In addition, four months following the completion of Experiment 2, follow-up data collected during a maintenance condition showed continued high levels of therapist and client behavior. Finally, a panel of expert peers indicated that each response category was judged highly relevant to the behavioral assessment process.     

REDUCTION OF CIGARETTE SMOKING IN A UNIVERSITY CAFETERIA

Passive smoking has been shown to be hazardous to the health of nonsmokers. Given this documented link between exposure to smoke-filled environments and deleterious health consequences, there is a need to develop effective procedures that establish and maintain no-smoking areas in various public settings. The present study focused on decreasing cigarette smoking in a section of a university cafeteria. Posting of no-smoking signs was found to decrease levels of smoking only minimally. However, when smokers were verbally prompted not to smoke, in the presence of the signs, marked decreases in smoking occurred in the target area.     

Positive and negative contrast as a function of component duration for key pecking and treadle pressing

Pigeons responded on several multiple schedules for food reinforcers. The duration of the components varied from four seconds to 16 minutes. The absolute size of positive (Experiment 1) and negative (Experiment 2) behavioral contrast varied inversely with component duration when key pecks produced the reinforcers. The absolute size of negative contrast varied directly with component duration, when treadle presses produced the reinforcers (Experiment 3). These results conform to theories that suggest that positive and negative contrast are symmetrical when pigeons peck keys. They also conform to theories that suggest that the same principles do not govern contrast when pigeons peck keys as when they press treadles. Finally, the results support the measurement of behavioral contrast by the differences between baseline rates of responding and the rates emitted when contrast is present.
