Improving dietary practices of elderly individuals: the power of prompting feedback, and social reinforcement.

Three intervention packages consisting of (a) enhanced prompts, feedback, and social reinforcement; (b) a lottery; and (c) serving as a confederate were added and removed in sequence as adjacent conditions in an extended withdrawal design to assess their effects on the dietary choices of elderly persons. Participants were 3 elderly residents of an independent living facility who were identified as making consistently poor dietary choices and who had medical conditions that necessitated changes in their eating habits. All 3 participants demonstrated a marked increase in healthy choices of food items in response to the package of enhanced prompts, feedback, and social reinforcement. No additional increase occurred with the introduction of the lottery and serving as a confederate. Food-choice data indicated that most of these improvements could be attributed to healthier entree and dessert choices. Group data for all residents suggested small improvements in dietary practices during the three intervention conditions, with the largest proportion of the group's healthy choices occurring when the lottery was added to enhanced prompts, feedback, and social reinforcement. Food-choice data indicated that most of these improvements could be attributed to healthier dessert choices alone.

Training of instrumental responses in dogs socially reinforced by humans.

The motivational bases of the social reinforcement in human-dog relations were examined. In experiment I, performed on seven dogs, it was found that dogs were able to learn and sustain the natural responses of sitting, paw extension, and lying prostrate to conditional stimuli in the form of vocal commands reinforced only by social rewards given by the experimenter, such as petting and vocal encouragement. Overtraining did not produce deterioration of performance but, on the contrary, the continual decrease of latencies. It was evidenced that tactile stimulation plays an important role in social reward. In experiment II, instrumental responses to the auditory conditional stimuli were elaborated in two groups of dogs. The first group (nine dogs) was reinforced by food, and the second group (eight dogs) was reinforced exclusively by petting. A similar course of learning and level of performance during overtraining sessions in both groups indicated that petting serves as a good reinforcement, with rewarding value comparable to that of food reinforcement. It is suggested that a strong rewarding effect of pleasurable sensory stimuli occurs in the formation of the bond between dog and human and in the learning of different tasks.

Social reinforcement of substance abuse treatment aftercare participation: Impact on outcome.

Although adherence to aftercare therapy in substance abuse treatment is associated with improved outcome, little research has explored the effects of adherence interventions on outcome. We compared 20 graduates of our 28-day intensive treatment program who received a standard aftercare orientation with 20 graduates who received this intervention plus social reinforcement of aftercare group therapy attendance. The social reinforcement group showed less alcohol use than the standard care group at a 6-month follow-up assessment as measured by the Addiction Severity Index (ASI), but not less drug use. Additionally, compared to standard care, the social reinforcement participants were more likely to be abstinent at the 6-month follow up (76% vs. 40%). The groups did not differ on hospital readmission rates over a 12-month follow-up period. Additionally, the social reinforcement group showed better long-term aftercare attendance compared to the standard care group.

Effects of social reinforcement on motor performance of trainable retarded students on speed and persistence tasks.

The effects of social reinforcement on two motor tasks by 40 retarded subjects with high and low MAs were investigated. Ages ranged from 10 to 18 yr., M = 14.46 yr. Mean IQ was 46.82; mental age for the high subjects was 8.09 yr., for the low 5.45 yr. Significant main effects for social reinforcement were found for the persistence measure but none for the speed measure. The effectiveness of praise on retarded subjects' performance is related to the type of motor task used.

Preinstitutional social deprivation, responsiveness to social reinforcement, and IQ change in institutionalized retarded individuals.

Mentally retarded individuals who had been examined on a task measuring responsiveness to social reinforcement after 3 weeks and after 3 years of institutionalization were examined after 6 years of institutionalization. IQ changes were also examined. For familially retarded subjects, a linear decrease in responsiveness to social reinforcement and a linear increase in IQ was found from the 1st to the 6th year of institutional life. No changes in responsiveness to social reinforcement or IQ were found over the 6 years for nonfamilially retarded subjects.

The effects of competition and social reinforcement upon perceptual motor performance.

Junior high school boys (n=180) performed 40 trials on the ball roll-up task in order to determine whether competition, initial ability level, and social reinforcement interact to influence performance. A 3 x 2 x 3 x 8 factorial design, with repeated measures on the last factor (initial ability level x competition x social reinforcement x blocks of trials) was used. The analysis of the data demonstrated that: (a) competition, initial ability level, and social reinforcement factors did not interact with one another; (b) social reinforcement (reproof) facilitated performance, while competition had no effect; and (c) the competition group had a greater tonic heart rate (increase from basal) than the noncompetitive group. Although it was not entirely clear why changes in the performance of the experimental groups did not accompany the changes in the groups' tonic heart rate, it was concluded that competition was an incentive.

Effects of vestibular rehabilitation and social reinforcement on recovery following ablative vestibular surgery.

This study investigated the relative effects of vestibular rehabilitation (VR) and social reinforcement (SR) on recovery following ablative vestibular surgery. Twenty-four subjects were randomly assigned to three treatment groups of either VR with SR, VR without SR, or general range of motion (ROM) exercises with SR. Outcome measures included equilibrium scores in dynamic posturography, asymmetry index in rotation testing, motion sensitivity quotient (MSQ), and dizziness handicap inventory (DHI). A multiple comparison of the overall outcome measures showed no significant differences in group performance over an 8-week period. When individual outcome measures were compared, MSQ and DHI results at the end of the 8-week treatment period revealed less motion sensitivity and dizziness handicap in groups who received VR, with or without SR, as compared with the group who received ROM exercises. These results suggest that after a vestibular injury most patients can effectively utilize central compensation mechanisms to recover from such an injury, regardless of the type of therapeutic intervention used. On the other hand, the reduction in motion sensitivity and dizziness handicap for patients who received VR could indicate a more rapid and complete recovery for these patients. This investigation is continuing as a long-term follow-up study to determine whether there are any long-term benefits in participating in a VR program.

Contingent social reinforcement for fluid compliance in a hemodialysis patient.

Two approaches, (a) patient education and (b) compliance-contingent social reinforcement, were employed to improve compliance with fluid restrictions in a chronically noncompliant hemodialysis patient of borderline intellectual functioning. Results indicated that only social reinforcement led to improved compliance (i.e., decreased intersession weight gain). Treatment effects were well maintained at both 3- and 6-month follow-ups. Contingency management strategies are recommended as a potentially cost effective treatment for noncompliance in hemodialysis patients.

Social reinforcement of operant behavior in rats: a methodological note.

An apparatus was developed to study social reinforcement in the rat. Four Long-Evans female rats were trained to press a lever via shaping, with the reinforcer being access to a castrated male rat. Responding under a fixed-ratio schedule and in extinction was also observed. Social access was found to be an effective reinforcer. When social reinforcement was compared with food reinforcement under similar conditions of deprivation and reinforcer duration, no significant differences were observed.
