93. Count Your Chews! A Self-Monitoring Intervention to Increase Chewing Efficiency
Area: DEV; Domain: Applied Research

Abstract: Oral-motor skill deficits and food selectivity often coincide, particularly when it comes to the consumption of regular texture foods. Common interventions that are used to address food selectivity include differential reinforcement, escape extinction, and demand fading (Silverman, 2016). However, when an individual’s food selectivity is more closely related to oral-motor skill deficits or delays, these interventions may not be appropriate or effective. There is limited research on the use of behavioral interventions to address chewing efficiency, largely because these concerns are treated primarily by speech language pathologists or occupational therapists, and not by behavior analysts. The current study aimed to fill this gap in the literature by developing a self-monitoring intervention to decrease the number of chews and the latency to mouth clean regular texture food using a multiple baseline design across foods. Results indicated that this intervention was effective at increasing the efficiency of chewing for this participant.
 
94. Does the Speaker’s Behavior Change Depend on Visibility of the Face in an Online Meeting?

Discussant: Alejandro Leon (University of Veracruz)
Abstract:

Whether or not others can see your face and whether or not you can see other’s face would affect your online communication. The purpose of this study was to examine how speech behavior changes depending on (1) whether or not the participants show their own face to the conversation partner, and (2) whether or not the face of the conversation partner can be seen, through the online meeting. Two participants, who have experienced selective mutism, were assigned to different experiment conditions. We used A-B-A-B reversal design. 3 dependent variables (response latency, speaking duration, and the number of spoken characters) were measured by video-coding. During each session, answers to 5 questions were recorded. The results for Participant A showed that there was no difference in speech behavior depending on whether the participant could see or could not see the other’s face, regardless of visibility of their own face. On the other hand, the results for Participant B showed that their response latency was shorter in the condition in which they did not show their face compared to the condition in which they show their face. This difference between conditions was observed only when the face of the partner was not visible.

 
95. Extending the Joy: Practical Functional Assessment and Skill-Based Treatment in a Rural Public School Setting with a Student Classified With an Intellectual Disability with Comorbidity

Abstract:

Practical Functional Assessment (PFA) and Skill-Based Treatment (SBT) are well established for treating challenging problem behaviors for students with autism spectrum and related disorders. Applications of Practical Functional Assessment and Skill Based Treatment for individuals outside of that population are more limited in nature (Coffey et al, 2020). Further, information specific to implementation in rural public school settings are even more so. In this case study, the implementation of Practical Functional Assessment and Skill Based Treatment for an elementary student classified with intellectual disability with co-morbidities demonstrated successful outcomes resulting in decreased eloping and classroom disruption, improved task completion and cooperation with teacher instructions. Follow up data in the following school year reveals increases between pre- and post- scores on the Behavioral Health Index. Additionally, the student has maintained desired effects to the extent that one on one assistance from a designated paraprofessional is no longer needed to support academic and behavioral needs.

 
96. Evaluation of Simultaneous Presentation to Increase Chewing in a Child With a Feeding Disorder

Abstract:

Chewing is a behavior that emerges in infancy and develops into a complex chain of behaviors through increased exposure to table food presented during childhood (Volkert et al., 2014). For children with feeding disorders, however, chewing may be underdeveloped or absent, resulting in a potential need for therapeutic intervention. Researchers have shown that simultaneous presentation, a procedure in which a nonpreferred food is presented with a preferred food, is an effective intervention for increasing acceptance (e.g., Ahearn et al., 2003) and decreasing packing (i.e., holding food in mouth; Whipple et al., 2020) in children with feeding disorders, but its application towards increasing chewing has not been previously explored. In the current case study, we evaluated simultaneous presentation as part of a treatment package with demand fading (i.e., bolus fading) and differential reinforcement of alternative behavior, to increase chewing of nonpreferred foods for a child with a feeding disorder. Results showed that chewing of nonpreferred foods increased and progress maintained when caregivers faded out the preferred food during outpatient therapy. We discuss these results and provide considerations for using simultaneous presentation as an intervention to increase chewing and promote age-typical feeding in children with feeding disorders.

 
97. Evaluation of Changes in Preference for Mand Modality

Abstract: The purpose of this study was to evaluate changes in preference for the type of mand modality used by a 2-year-old boy with developmental disabilities. This study was completed in three phases via telehealth. Following a functional analysis and mand modality assessment, Phase 1 consisted of functional communication training (FCT) across two mand modalities (i.e., manual sign and picture card) within a multiple schedules design until independent manding was consistently demonstrated. In Phase 2, a mand preference assessment (MPA) was conducted within a concurrent schedules design to determine mand modality preference. Phase 3 involved placing both mand modalities on extinction within a multiple schedules design to determine behavioral persistence of manding across the two modalities. FCT and MPA phases were repeated across this study in an ABACAB design. Phase 1 results showed that independent manding occurred at similar levels across modalities during the initial implementation of FCT. The MPA conducted in Phase 2 indicated a preference for manual sign. In Phase 3, greater persistence was demonstrated with the picture card during extinction and a shift in preference for the picture card was later observed in the second MPA. Hypotheses for the shift in preference and clinical implications will be discussed.
 
98. Use of Area Under the Curve as a Measure of Magnitude of Mand Modality Preference

Abstract: Research on functional communication training (FCT) has demonstrated several benefits associated with using a high preferred mand modality option, including more rapid proficiency, better maintenance, and greater persistence of communication. Mand modality preference is often identified as the modality selected or used most often during a mand modality preference assessment (MMPA), and the magnitude of preference is often indicated by the difference in percentage of selections or the ratio of selections between two options. In this study we evaluated a different method for measuring the magnitude of preference based on the results of mand modality preference assessments. Using several participants from a larger research project that included MMPAs conducted within a concurrent operants arrangement, we first measured area under the curve (AuC) for each modality evaluated within a participant’s MMPA. To determine magnitude, we calculated the difference between the AuC for each modality. Although each participant demonstrated a clear preference for a single mand modality in the preference assessments, we found that the magnitude of preference based on the AuC varied significantly. Research and clinical implications of using the AuC method for determining the magnitude of preference are discussed.
