Document Summary
Week 5 june 1 st , 2015. Once an error occurs, it tends to re-occur many times. Extinction (lack of reinforcement) can produce undesirable emotional reactions: can occur along different dimensions of stimuli. E. g. , volume of speech, content of speech, physical cues, environmental cues, etc. Stimulus discrimination training versus fading: both are focused on establishing appropriate stimulus control over a certain behavior, given that the target behavior already occurs at least occasionally. Implementing fading effectively: careful consideration of the final desired stimulus. The stimulus that you are aiming for at the end of the fading procedure. Need to consider reinforcement in the natural environment: choosing the starting stimulus: a prompt. A stimulus that reliably evokes the target behavior, to help start the fading procedure. Extra-stimulus: adding something to the environment to help promote the behavior. Errors may signal that the fading was done too quickly, and you should backtrack to.
