Background: Previous reviews did not include sources that were published in the last 14 years, indicating a need for an updated synthesis on the time delay literature. Objectives: This review was designed to synthesize outcomes for studies assessing time delay prompting procedures for teaching young children. Data sources: PsycINFO and ProQuest…

Lag reinforcement schedules have been shown in previous research to be an effective intervention for teaching verbal and nonverbal response variability to individuals with developmental disabilities. In more recent research, variability itself has been considered a reinforceable behavior in its own right (Susa & Schlinger, The Analysis of…

Introduction: Constant time delay is an evidence-based practice to teach sight word recognition to students with a variety of disabilities. To date, two studies have documented its effectiveness for teaching braille.

Participants viewed the entire task on…

Many everyday matching tasks taught to persons with developmental disabilities are visual-visual non-identity matching (VVNM) tasks, such as matching the printed word DOG to a picture of a dog, or matching a sock to a shoe. Research has shown that, for participants who have failed a VVNM prototype task, it is very difficult to teach them various…
