The present study evaluated a systematic instructional package including the system of least prompts (SLP) to teach differentiation and selection of tangible symbols to continue activities for two children with complex support needs and deafblindness (DB). A multiple probe design across three symbols was used to evaluate the intervention package…

Discrete trial teaching (DTT) is a common teaching methodology used within intervention for autistics/individuals diagnosed with autism spectrum disorder (ASD). Practice recommendations related to using DTT for receptive language instruction includes the desired size of the array of stimuli to be presented. Some recommendations include ensuring…

The use of auditory stimulation to decrease vocal stereotypy in individuals with autism spectrum disorder has been the focus of several studies in recent years. Some of these studies investigated the use of auditory stimulation in the form of music, some evaluated the use of other interventions in tandem with auditory stimulation, and others…

In the context of Social Stories™, we compared visual attention to social scenes using BoardMaker™ versus photographic stimuli among typically developing (TD) children and age-matched children with ASD. For visual attention, the dependent measures were the number of fixations and fixation time to eye, mouth, and 'other' (background) areas of…

In the present study, we aimed to make an evaluation, conduct comprehensive descriptive analyses, and calculate the effect sizes of studies which compare AAC applications designed according to single-subject research designs and conducted for individuals with ASD. Within the scope of this aim, 21 studies meeting the inclusion criteria were…

This study compared no-no prompt to flexible prompt fading to teach four children diagnosed with autism spectrum disorder expressive labels. Using an adapted alternating treatment design, we evaluated the effectiveness of both systems to teach each participant to expressively label 10 pictures of athletes. The researchers evaluated the…

The purpose of this study was to evaluate the effects of different speech-generating device displays and vocabulary organizations on the acquisition of multi-step requesting responses in children with autism spectrum disorder (ASD). Four young children with ASD were taught to use an iPad® application to make requests using both a taxonomically…

The purpose of this study was to compare the effects of three video perspectives: point-of-view, scene view, and a combination of point-of-view and scene view on task completion by three young adults with moderate intellectual disability. The comparison was made, using an Adapted Alternating Treatments Design, across three sets of fundamentally…

No studies of parent-implemented behavior interventions for children with autism spectrum disorders (ASD) have purposefully examined their effectiveness and acceptability with African American families. The present study used a multiple baseline across participants design to evaluate the effectiveness of parent-implemented differential…

The study investigated sequence learning from stochastic feedback in boys with Autistic Spectrum Disorder (ASD) and typically developed (TD) boys. We asked boys with ASD from Nigeria and the UK as well as age- and gender-matched controls (also males only) to deduce a sequence of four left and right button presses, LLRR, RRLL, LRLR, RLRL, LRRL and…

The Picture Exchange Communication System (PECS) is an augmentative and alternative communication (AAC) program used to teach functional requesting and commenting skills to people with disabilities (Bondy & Frost, 1993; Frost & Bondy, 2002). In this study, tangible symbols were added to PECS in teaching requesting to four students (ages 7-14) with…
