‘He's got his father's bias’: Parental influence on weight bias in young children

Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3‐year‐old children and their parents, who provided data at baseline and 1 year later. Parents completed self‐report body size attitude and dieting measures. Child weight bias and awareness of weight loss strategies were assessed through interview. Over time, negative associations with large bodies and awareness of weight loss strategies increased. Fathers’ attitudes prospectively predicted boys’ weight bias and awareness of weight loss strategies. Among girls, parental attitudes were less predictive. Findings confirm the importance of fathers in the development of boys’ body attitudes and inform prevention programmes.     

The functional role of preschoolers' verbalizations in the generalization of self-instructional training

We examined the functional role of verbalizations in the generalization of self-instructional training with preschoolers. Children learned to overtly self-instruct during classroom work periods prior to covert training. Data were collected on children's acquisition of verbal regulation during training and on overt use of self-instructions in the classroom generalization setting. Results of a multiple baseline design across subjects indicated that treatment effects were evident in the training setting but did not generalize to the classroom until children were emitting overt self-instructions in the classroom itself. The production of self-verbalizations in the generalization setting was related to changes in correct responding, on-task behavior, and efficiency in completing academic work.     

EFFECTS OF SELF-EVALUATION ON PRESCHOOL CHILDREN'S USE OF SOCIAL INTERACTION STRATEGIES WITH THEIR CLASSMATES WITH AUTISM

This study investigated effects of a self-evaluation procedure on preschool children's use of social interaction strategies among their classmates with autism. Three triads of children (comprised of 1 trained normally developing peer, 1 untrained peer, and 1 child with autism) participated. A multiple baseline design across subjects was used to demonstrate that peers who were taught facilitative strategies increased their use of strategies only after the self-evaluation intervention was introduced. Improvements in social behavior of children with autism was associated with peers' increased strategy use. Untrained peers demonstrated little change in their social behavior. Treatment effects were replicated when trained peers were asked to use self-evaluation with other children with autism during other play times. Self-evaluation procedures enhanced the use of social interaction strategies on the part of normally developing peers during social skills interventions.     

AN ANALYSIS OF THE EFFECTS OF MULTIPLE SETTING EVENTS ON THE SOCIAL BEHAVIOR OF PRESCHOOL CHILDREN WITH SPECIAL NEEDS

We examined the effects of four combinations of setting events on the social interactions of 7 preschool children with social delays. In Study 1, the status of the teacher, activity materials, and peer varied across conditions. In Study 2, the status of the teacher and materials varied across conditions. Within the combinations of setting events, we also examined teacher behavior. Teacher presence and absence was varied in both studies. The type and rate of teacher prompting were varied in Study 2. The four combinations of setting events produced different rates of social behavior by the children with social delays. The optimal combination of setting events for promoting peer interaction and reducing teacher—child interaction included teacher absence from the activity, a limited number and form of materials, and children paired with a socially skilled partner.     

FADING TEACHER PROMPTS PROM PEER-INITIATION INTERVENTIONS FOR YOUNG CHILDREN WITH DISABILITIES

This study examined a system for fading teacher prompts to children who served as peers in peer-initiation interventions for young children with disabilities. A teacher taught peers to direct social initiations to children with disabilities, provided verbal prompts for those initiations, and introduced a system that provided peers with visual feedback about the social interactions of the children with disabilities. She then systematically withdrew the verbal prompts to peers, and subsequently faded the visual feedback system. Peer initiations increased when the intervention began and resulted in increases in social interaction for the children with disabilities. As the teacher systematically faded the prompts and visual feedback to the peers, social interaction continued at the levels found during intervention and was maintained during a short maintenance period.     

Programming maintenance after correspondence training interventions with children

Interventions were employed to program maintenance following correspondence training. The use of reinforcement of verbalization and a mixed sequence of procedures designed to establish indiscriminable contingencies was evaluated in multiple-baseline designs across subjects and behaviors. The results indicated that target behaviors were maintained under less intrusive interventions and in the absence of programmed contingencies during extended follow-up conditions. The results are discussed in terms of changes in reinforcement schedules established in maintenance interventions.     

TRAINING AND GENERALIZATION OF REACH-GRASP BEHAVIOR IN BLIND,RETARDED YOUNG CHILDREN

The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction.     

Delayed reinforcement as an indiscriminable contingency in verbal/nonverbal correspondence training

We investigated the programming of generalization and maintenance of correspondence between verbal and nonverbal behavior in a preschool setting. Four children participated in a series of multiple-baseline designs. In Experiment 1, delayed reinforcement of verbal behavior effectively controlled maintenance of correspondence with previously trained responses and also resulted in generalization of correspondence to one untrained response. As the latter effect was limited, Experiment 2 was a further assessment of the effects of delayed reinforcement of generalization of correspondence to untrained responses, and consistent generalization was shown. Experiment 2 also showed that generalization, if lost, could be recovered through use of "booster training," in which the original contingencies were reinstated for a brief period. Experiment 3 provided replications, with two additional children, of the effects of delayed reinforcement on maintenance of correspondence. Results are discussed in terms of using delayed reinforcement as an indiscriminable contingency.
