Errorless Training - Topic 49

What is it?

Errorless training involves manipulating the relevant and irrelevant task stimuli so that few or no errors occur while a target response is being taught (Snell, & Brown, 2011). Mueller, Palkovik, and Maynard (2007) listed errorless teaching procedures as the following: stimulus fading, stimulus shaping, response prevention, delayed prompting, superimposition with stimulus fading, and superimposition with stimulus shaping. These procedures refer to a variety of discrimination learning techniques that aim to minimize incorrect responding (Mueller et al., 2007). All of them involve two specific rules. First, the initial responding is easy and second, a students’ progress toward to the target behavior is gradual (Lancioni, & Smeets, 1986).

Why is it important?

In contrast to trial-and-error training, errorless training does not allow the student to make considerable errors while learning the target behavior. Research has shown that it is effective in establishing discrimination. Students with severe disabilities who have difficulty in making simple and conditional discriminations can benefit from errorless training (Graff & Green, 2004).
