This study evaluated the effects of progressive time delay (PTD) to teach four elementary students with intellectual disability on how to self-instruct using a video activity schedule. A single-case multiple probe across participants design with a multiple probe across environments design for each participant was used to assess the generalization…

This study used a multiple probe across participants design to (a) evaluate the use of system of least prompts to teach students to self-instruct and (b) evaluate the use of a mobile device for a video activity schedule of a functional daily living skill. In baseline, the classroom teacher asked participants to make a snack and collected…

Peer support arrangements are an evidence-based practice for increasing interactions between students with severe disabilities and their peers in general education classrooms, but it is unclear how interactions vary across instructional formats or generalize outside the classroom. In this single-case design study, we tested the efficacy of peer…

The history of intelligence test use in Japan began in the early 20th century. Since the 21st century, three major intelligence tests, namely, the Wechsler Intelligence Scales, the Kaufman…

Given that early caregiver concerns may be different for children who go on to receive a diagnosis of autism spectrum disorder versus another developmental disability, early caregiver concerns may differ for girls. Using a community-based sample of children (n = 241), we examined the extent to which gender differences may be related to caregiver…
