Promoting safety belt use among state employees: the effects of prompting and a stimulus-control intervention.

This study assessed the effects of dashboard stickers and signature sheets on safety belt use among occupants of state-owned vehicles in three Florida agencies. The stickers and signature sheets contained information regarding a regulation requiring safety belt use and a consequence of a 25% reduction in benefits for noncompliance if the driver were to become involved in an accident. Safety belt use significantly increased during the intervention phase in all three agencies and maintained variable but high levels for 5 months. In Agency 1 and Agency 2 (stickers plus signature sheets) safety belt use increased from averages of 10.8% and 9.4% during baseline to 57.4% and 47.0%, respectively, during intervention. In Agency 3 (stickers only) the rates of safety belt use averaged 9.7% during baseline and 38.0% during intervention. Some increases in private vehicle use were observed. A substantial reduction in workers'' compensation claim costs was shown for the target agencies with some reductions also shown in the nontarget agencies.     

TEACHING HOME SAFETY AND SURVIVAL SKILLS TO LATCH-KEY CHILDREN: A COMPARISON OF TWO MANUALS AND METHODS

I evaluated the influence of two training manuals on latch-key children's acquisition of home safety and survival skills. The widely used, discussion-oriented “Prepared for Today” manual was compared with a behaviorally oriented “Safe at Home” manual. Data were scored by response criteria developed by experts and by parents' and experts' ratings of children's spontaneous answers. With both methods of scoring, three behaviorally trained children demonstrated clear and abrupt increases in skill following training in each of seven trained modules, and these increases largely persisted in real world generalization probes and at 5-month follow-up. Smaller and less stable increases in skill were found in the three discussion-trained children across the seven modules; lower skill levels were also seen in real world generalization probes and at follow-up. Neither group of children demonstrated skill increases in home safety areas that were not explicitly trained. Both training methods produced small decreases in children's self-report of general anxiety and anxiety concerning home safety. Results are discussed in terms of their implications for cost-effective training of latch-key children.     

Choosing between predictable shock schedules: Long- versus short-duration signals

Two experiments assessed the relative aversiveness of different duration preshock signals (5 and 20 seconds) and different duration stimuli identifying shock-free periods. In the first experiment, the responding of 15 of 18 rats was maintained when it produced changes from a predictable-shock condition with a 5-second preshock signal to an identical schedule with a 20-second preshock signal; responding was not maintained when it produced the opposite changes. These results occurred with intershock intervals of both 120 seconds and 240 seconds. The second experiment assessed whether changing to the 20-second schedule was maintained by properties of the preshock signals identifying the shock periods or by properties of the stimuli identifying the shock-free periods. Four subjects were given training with the two signaled schedules in an operant chamber and then later given off-baseline preference tests in a shuttlebox. When given a choice between preshock signals, subjects chose the 5-second signals over the 20-second signals. However, when given a choice between stimuli identifying shock-free periods, subjects chose the stimulus identifying the shorter shock-free periods (i.e., the one previously correlated with the 20-second signals). These findings are discussed within the Rescorla and Wagner model of stimulus compounds and within the context of safety as a contrast phenomenon.     

A temporal parameter influencing choice between signalled and unsignalled shock schedules

The present study investigated whether choice of a signalled variable-time shock schedule over an unsignalled one was influenced by the average intershock interval. Eight rats were given a choice between signalled and unsignalled shock schedules in a series of conditions with average intershock intervals of 510, 270, 150, 90, 60, and 45 sec. Each test condition was preceded by a training-baseline condition, and schedule values were arranged in an ascending (four subjects) or descending (four subjects) order. Choice of the signalled conditions was directly related to the average intershock interval of the variable-time schedule for six of the eight subjects. The per cent of time in the signalled condition was highest when the average intershock interval was 150 sec or longer and lowest when the average intershock interval was 45 sec. The findings were interpreted as being due to changes in the safety features of the signalled schedule, rather than to changes in the average intershock interval per se.     

PROMPTING PATRON SAFETY BELT USE AT A RESTAURANT

A reversal (ABABAB) design was used to assess the effects of a verbal prompt on safety belt use of restaurant patrons. A verbal prompt delivered by employees at the exit door resulted in an average increase of 20% in safety belt use by drivers leaving the restaurant. A previous study provided this type of antecedent immediately before supermarket patrons entered their vehicles. This effort demonstrates the effects of a verbal prompt with greater latency between the prompt and target response.     

A single-subject approach to evaluating vehicle safety belt reminders: Back to basics

A single-subject ABA reversal design was applied to evaluate the effectiveness of a limited 8-s safety belt reminder system and two modified reminder systems (a delayed and second reminder) to increase the safety belt use of 13 drivers. The research was conducted with a specially equipped research vehicle that permitted the manipulation of different safety belt reminder stimuli and the unobtrusive recording of a driver's belt use. For 2 subjects, the limited 8-s reminder increased safety belt use. For another 2 subjects, the second reminder markedly increased belt use. Some subjects were uninfluenced by the reminder systems presented; others always buckled up during both baseline and intervention conditions. The approach and results are discussed with regard to the application of behavior analysis methodologies (e.g., cumulative records) and principles (e.g., schedules of reinforcement) to advance the utility and investigation of safety belt reminder systems.     

TEACHING ADULTS WITH SEVERE AND PROFOUND RETARDATION TO EXIT THEIR HOMES UPON HEARING THE FIRE ALARM

Prompting, modeling, and differential reinforcement with client-chosen rewards were used to teach 3 nonverbal people with severe to profound mental retardation to exit their group homes at the sound of the house fire alarm, using a multiple baseline design. All 3 participants learned to exit independently in less than 2 min in all experimenter-initiated surprise fire drills and in the majority of staff-initiated surprise fire drills. Each participant was also able to exit from five areas of the house from which teaching was not done.     

PROMPTING PATRON SAFETY BELT USE AT A SUPERMARKET

We used a reversal (ABAB) design to assess the effects of a personal prompt on safety belt usage by grocery store patrons. A personal prompt delivered by grocery carriers resulted in a 12% increase in the number of patrons exiting the parking lot with their safety belts buckled. This simple, low-cost intervention offers potential savings to society from increased safety belt use.     

Vis‐à‐vis the Couch: Where is Psychoanalysis?

The author discusses ways in which the couch or chair (lying down versus sitting up) may be used to maintain safety and defend against perceived dangers in the analytic process. Several dialectics are relevant as they intersect with that of danger and safety, including engagement/privacy, interiority/exteriority and subject/object. The author discusses these dialectics in terms of the ways in which the analyst is used at different points in time, i.e. as an objectifi ed other, a subjective object or part-object, or as a subject with an internal world. The therapeutic action associated with sitting up (versus lying down on the couch) has been undertheorized, despite the fact that many, if not most, analysands sit up for some portion of their analysis. Through the use of a heuristic visual-spatial metaphor as represented by the use of the couch or chair, the author discusses the signifi cance of lying down and sitting up for therapeutic action.
