Exploring Issues of Generalization and Maintenance in Training Instructional Aides in a Public School Setting

In today’s climate, with the ever-increasing demand for competent behavior analytic services, it is necessary for behavior analysts to work across a variety of settings, including home, school, and community, overseeing instructional aide staff as the frontline providers of applied behavior analysis (ABA) services. It is common practice for ABA practitioners to provide the supervision and training to parents, caregivers, and direct-care staff, who may have limited knowledge and experience within the field of ABA. In 2013, the Behavior Analysis Certification Board (BACB^®) initiated an effort to establish standards for the training of instructional aides and direct-care staff in the delivery of instructional and treatment services based on the principles of ABA. This new standard and credential is known as a Registered Behavior Technician? (RBT^®). The purpose of this study was to evaluate the training process outlined by the BACB, focusing specifically on the generalizability and long-term maintenance of newly acquired skills taught through a competency-based approach, to novel opportunities for implementation. Training was conducted through two methods: in vivo training with clients versus role-play with peers. Both these types of staff training approaches are commonly used instructional practices in the field of ABA.     

Early development of letter specialization in left fusiform is associated with better word reading and smaller fusiform face area

A functional region of left fusiform gyrus termed “the visual word form area” (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5‐ and 6‐year‐old early kindergarten children (N = 48) with little or no school‐based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter‐sensitive cortex (greater activation for letters versus faces) and letter‐specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word‐reading ability and (b) signal change and size of face‐sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters). Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter‐sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right‐hemisphere dominance for face perception.
