EXAMINING THE GENERALITY OF CHILDREN'S PREFERENCE FOR CONTINGENT REINFORCEMENT VIA EXTENSION TO DIFFERENT RESPONSES, REINFORCERS, AND SCHEDULES

Studies that have assessed whether children prefer contingent reinforcement (CR) or noncontingent reinforcement (NCR) have shown that they prefer CR. Preference for CR has, however, been evaluated only under continuous reinforcement (CRF) schedules. The prevalence of intermittent reinforcement (INT) warrants an evaluation of whether preference for CR persists as the schedule of reinforcement is thinned. In the current study, we evaluated 2 childrens preference for contingent versus noncontingent delivery of highly preferred edible items for academic task completion under CRF and INT schedules. Children (a) preferred CR to NCR under the CRF schedule, (b) continued to prefer CR as the schedule of reinforcement became intermittent, and (c) exhibited a shift in preference from CR to NCR as the schedule became increasingly thin. These findings extend the generality of and provide one set of limits to the preference for CR. Applied implications, variables controlling preferences, and future research are discussed.

PREVENTION OF PROBLEM BEHAVIOR BY TEACHING FUNCTIONAL COMMUNICATION AND SELF-CONTROL SKILLS TO PRESCHOOLERS

We evaluated the effects of the preschool life skills program (PLS; Hanley, Heal, Tiger, & Ingvarsson, 2007) on the acquisition and maintenance of functional communication and self-control skills, as well as its effect on problem behavior, of small groups of preschoolers at risk for school failure. Six children were taught to request teacher attention, teacher assistance, and preferred materials, and to tolerate delays to and denial of those events during child-led, small-group activities. Teaching strategies included instruction, modeling, role play, and differential reinforcement. Six additional children randomly assigned to similarly sized control groups participated in small-group activities but did not experience the PLS program. Within-subject and between-groups designs showed that the PLS teaching procedures were functionally related to the improvements and maintenance of the skills and prevention of problem behavior. Stakeholder responses on a social acceptability questionnaire indicated that they were satisfied with the form of the targeted social skills, the improvements in the childrens performance, and the teaching strategies.

An evaluation of the generalization and maintenance of functional communication and self‐control skills with preschoolers

The preschool life skills (PLS) program (Hanley, Heal, Tiger, & Ingvarsson, 2007; Luczynski & Hanley, 2013) involves teaching social skills as a means of decreasing and preventing problem behavior. However, achieving durable outcomes as children transition across educational settings depend on the generalization and long-term maintenance of those skills. The purpose of this study was to evaluate procedures for promoting generalization and long-term maintenance of functional communication and self-control skills for 6 preschool children. When the childrens social skills decreased across repeated observations during a generalization assessment, we incorporated modifications to the teaching procedures. However, the effects of the modifications were variable across skills and children. Satisfactory generalization was observed only after the teacher was informed of the target skills and teaching strategies. Maintenance of most social skills was observed 3 months after teaching was discontinued. We discuss the importance of improving child and teacher behavior to promote generalization and maintenance of important social skills.

Toward meaningful outcomes in teaching conversation and greeting skills with individuals with autism spectrum disorder

We identified greeting and conversation deficits based on a parent interview and semistructured direct assessment for one child and two adolescents with autism spectrum disorder. We taught the greeting and conversation skills using behavioral skills training and within-session corrective feedback. A multiple baseline across conversation and greeting skills demonstrated experimental control over the effects of the teaching on acquisition and generalization to novel adults. We also conducted embedded reversals to assess maintenance of the acquired skills. Teaching produced robust acquisition, generalization, maintenance, and treatment extension for 15 of the 16 targeted skills across participants. Participant and parent reports indicated high levels of social validity for the intervention and outcomes. The results support individualized assessment and intervention for improving greeting and conversation skills during unscripted interactions, which are requisite for more extended and complex social interactions.

Evaluation of a Telehealth Training Package to Remotely Train Staff to Conduct a Preference Assessment.

Recent advancements in telecommunication technologies make it possible to conduct a variety of healthcare services remotely (e.g., behavioral-analytic intervention services), thereby bridging the gap between qualified providers and consumers in isolated locations. In this study, web-based telehealth technologies were used to remotely train direct-care staff to conduct a multiple-stimulus-without-replacement preference assessment. The training package included three components: (a) a multimedia presentation; (b) descriptive feedback from previously recorded baseline sessions; and (c) scripted role-play with immediate feedback. A nonconcurrent, multiple-baseline-across-participants design was used to demonstrate experimental control. Training resulted in robust and immediate improvements, and these effects maintained during 1- to 2-month follow-up observations. In addition, participants expressed high satisfaction with the web-based materials and the overall remote-training experience.

How should periods without social interaction be scheduled? Children's preference for practical schedules of positive reinforcement

Several studies have shown that children prefer contingent reinforcement (CR) rather than yoked noncontingent reinforcement (NCR) when continuous reinforcement is programmed in the CR schedule. Preference has not, however, been evaluated for practical schedules that involve CR. In Study 1, we assessed 5 childrens preference for obtaining social interaction via a multiple schedule (periods of fixed-ratio 1 reinforcement alternating with periods of extinction), a briefly signaled delayed reinforcement schedule, and an NCR schedule. The multiple schedule promoted the most efficient level of responding. In general, children chose to experience the multiple schedule and avoided the delay and NCR schedules, indicating that they preferred multiple schedules as the means to arrange practical schedules of social interaction. In Study 2, we evaluated potential controlling variables that influenced 1 childs preference for the multiple schedule and found that the strong positive contingency was the primary variable.

The Use of Protective Equipment in the Management of Severe Behavior Disorders

What do a roller-coaster harness, boxing gloves, a parachute, and a football helmet all have in common? They are all forms of protective equipment or restraints that allow individuals to safely engage in responses that would otherwise be quite dangerous. For example, a parachute allows a person to jump out of a plane flying 10,000 ft above the earth and, in almost all cases, reach the ground safely. In fact, Captain Joe Kittenger jumped from a gondola that was 102,800 ft (19.5 miles) above the earth and lived to tell about it. This amazing feat illustrates the extent to which protective equipment can reduce the health risks associated with dangerous or risky behavior.

Preschool life skills: Recent advancements and future directions

Over the past decade, researchers have replicated and extended research on the preschool life skills (PLS) program developed by Hanley, Heal, Tiger, and Ingvarsson (2007). This review summarizes recent research with respect to maximizing skill acquisition, improving generality, evaluating feasibility and acceptability, and testing predictions of the initial PLS study. For each area, we suggest directions for future research.

The Munroe-Meyer Approach: Continuous Integration of Didactic Instruction, Research, and Clinical Practice

Increased demand for applied behavior analysis (ABA) services has increased the need for additional masters-level practitioners and doctoral-level academicians and clinical directors. Based on these needs, the University of Nebraska Medical Center’s (UNMC) Munroe-Meyer Institute has developed a PhD program. The academic structure at UNMC allowed us to create our PhD program in a relatively quick and efficient manner. Our PhD program has many unique features, including (a) close integration of didactic instruction with clinical and research training provided by leading experts in ABA in which students immediately apply concepts introduced in the classroom during coordinated clinical and research practica; (b) structured grant writing training in which students learn to write and submit an NIH-level grant; (c) financial support in the form of a stipend of
