PSYB45H3 Chapter 9: Fading
Document Summary
The gradual change over successive trials of an antecedent stimulus that controls a response so that the response eventually occurs to a partially changed or completely new stimulus. Errorless discrimination is the use of a fading procedure to establish a stimulus discrimination so that no errors occur. In other words, errors are not necessary for learning to occur. Any characteristic that can be measured on some continuum. The final desired stimulus is the stimulus that will be found in the natural environment that you are trying to teach a person to respond properly to. A starting stimulus that reliably evokes the desired behavior. Supplemented antecedent stimulus provided to increase the likelihood that a desired behavior will occur, but that is not the final desired stimulus to control that behavior. Consist of alterations of the physical environment in a manner that will evoke a desired behavior.
