RESUMEN

Although feedback is a widely used intervention for improving performance, it is unclear what characteristics individuals prefer and what is necessary for it to be effective. The purpose of this study was to systematically extend Simonian and Brand (2022) by addressing the limitations of the study and adding a best-treatment phase. During an acquisition phase, participants received either positive, corrective, or no feedback upon task completion. Nine of 10 participants mastered the task that was associated with corrective feedback, and one participant mastered the task with no feedback. Eight participants completed a preference phase in which they were provided a choice of either positive or corrective feedback when learning to play a novel game. Half of the eight participants showed a preference for corrective feedback, and the remaining participants had mixed preferences. Overall, corrective feedback was more efficacious and more preferred than positive feedback.

RESUMEN

The current study evaluated the effectiveness of a treatment package including a behavior contract, brief portion selection training, and a food diary, to manage portion control in an adolescent female with autism. The behavior contract specified a reinforcement contingency for meeting a weekly goal that described how many servings the participant may consume but should not exceed during meals consisting of target foods. Results of the study demonstrated that the treatment package was successful in managing the number of portions the participant consumed across treatment and generalization sessions. • The flexible nature of the intervention may lead to greater treatment adherence • The intervention was rated with high social acceptability. • The intervention is generalizable to other naturalistic contexts. • The intervention may promote independence through teaching self-management skills.

RESUMEN

This study examined the effects of a self-instruction package comprised of a task analysis data sheet, detailed written instructions, and a small group performance feedback training on the training of 12 undergraduate students to conduct trial-based functional analyses (TBFAs). In contrast to previous research, training omitted technical language and did not include didactic instruction on the principles of applied behavior analysis or the underlying rationale for functional analysis methodology. Although the self-instruction package produced significant increases in performance and reliable data collection on the targeted problem behavior, small group performance feedback training was necessary to achieve mastery across all trial types. Results offer a socially valid training package to teach paraprofessionals to assist Board Certified Behavior Analysts® in conducting TBFAs in applied settings.

RESUMEN

Results of previous research evaluating sequential presentation of nonpreferred (NP) and high-preferred (HP) foods have been mixed, and little is known about how preferences for foods and the manner in which they are presented impact consumption. In many households, NP and HP foods are presented together on the same plate (total meal presentation). This was true for the participants included in this study; thus, total meal presentation served as a baseline against which to compare the effects of an appetizer presentation method and subsequently sequential presentation (differential reinforcement). Results demonstrated that presenting NP foods as an appetizer was not successful in increasing consumption. Consumption only increased after HP foods were made contingent on consumption of the NP food.

RESUMEN

Packing, which consists of holding food in the mouth for an extended time during meals, is a form of disordered feeding associated with pediatric feeding disorders. The behavior can disrupt the pace and completion of a meal and lead to increased risk of choking, inadequate food and liquid intake, and elevated caregiver stress associated with mealtimes. Applied behavior analysis research has developed and evaluated behavioral interventions to improve feeding by reducing packing. This systematic review extends prior research by synthesizing characteristics of the packing intervention literature, evaluating the certainty of the evidence provided by studies, identifying potential directions for future research, and discussing the results in the context of evidence-based practice.

RESUMEN

Rapid eating, a potentially dangerous and socially inappropriate behavior, has received relatively little attention in the literature. This study sought to extend the research in this area by further evaluating the effectiveness of a vibrating pager combined with a rule for increasing inter-response time between bites in one adolescent female diagnosed with autism. Results indicated that inter-response time increased from baseline only after a vocal prompt to "wait" was introduced across clinic and home settings. Implications for promoting autonomy in individuals with developmental disabilities are discussed.This antecedent-based intervention can easily be generalized to caregiversThe unobtrusive nature of the intervention allows for implementation in inclusive settingsThere are implications for promoting social skills in naturalistic environmentsThe intervention can promote independence through teaching self-management.

RESUMEN

The present study evaluated the effectiveness of two variations of a token economy for reducing disruptive behavior within a general education classroom. One variation involved a group contingency in which tokens were removed contingent on disruptive behavior (response cost), and the other variation involved a group contingency in which tokens were gained according to a differential reinforcement of other behavior schedule. Two elementary school teachers and their students participated. Results indicated that both procedures were effective in reducing the overall number of students disrupting; however, both teachers and students indicated a greater preference for the response cost condition. Implications for the use of these behavior management strategies in the classroom are discussed in terms of effectiveness and ease of implementation.

RESUMEN

The current study investigated the effectiveness of stating and modeling contingencies in increasing food consumption for two children with food selectivity. Results suggested that stating and modeling a differential reinforcement (DR) contingency for food consumption was effective in increasing consumption of two target foods for one child, and stating and modeling a DR plus nonremoval of the spoon contingency was effective in increasing consumption of the remaining food for the first child and all target foods for the second child.

RESUMEN

Few studies have examined the effects of the high-probability instructional sequence in the treatment of food selectivity, and results of these studies have been mixed (e.g., Dawson et al., 2003; Patel et al., 2007). The present study extended previous research on the high-probability instructional sequence by combining this procedure with low-probability demand fading with 2 boys with autism (9 and 10 years old) who had a history of food selectivity and engaged in active food refusal behaviors when presented with novel foods. Response requirements were faded gradually from responses the child would tolerate (e.g., touching the food) to the final requirement of chewing and swallowing the food. The antecedent-based intervention was implemented in the absence of escape extinction and was effective in increasing food consumption for both participants. Possible mechanisms responsible for the effectiveness of the intervention are discussed along with directions for future research.

RESUMEN

The purpose of the current study was to replicate the use of parents as therapists for experimental functional analyses of inappropriate mealtime behavior with multiple participants while measuring procedural integrity. Clear functions were identified, and high percentages of procedural integrity were obtained.

RESUMEN

Previous research has suggested that the availability of high-preference stimuli may override the reinforcing efficacy of concurrently available low-preference stimuli under relatively low schedule requirements (e.g., fixed-ratio 1 schedule). It is unknown if similar effects would be obtained under higher schedule requirements. Thus, the current study compared high-preference and low-preference reinforcers under progressively increasing schedule requirements. Results for 3 of the 4 participants indicated that high-preference stimuli maintained responding under higher schedule requirements relative to low-preference stimuli. For 1 participant, high-preference and low-preference stimuli were demonstrated to be equally effective reinforcers under increasing schedule requirements. Implications with respect to rate of performance and response patterns are discussed.

RESUMEN

Three-step prompting is a procedure commonly used in behavioral assessments and interventions; however, little research has evaluated the effects of this procedure on increasing children's compliance with caregiver requests. In this study, caregivers of children who demonstrated low levels of compliance were trained to use three-step prompting when presenting task requests to their children. Results indicated that training caregivers to implement this procedure decreased the frequency of caregiver-delivered prompts and increased compliance by the children.
