PSYB45H3 Chapter Notes - Chapter 10: Stimulus Control, Classical Conditioning, Weaning
Document Summary
Psyb45 chapter 10: changing the stimulus control of a behaviour with. Fading: 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 antecedent stimulus. In any situation in which a stimulus exerts strong control over a response, fading can be a very useful procedure for transferring the control of that response to some other stimulus: errorless discrimination (aka. Errorless learning) the use of a fading procedure to establish a stimulus discrimination so that no errors occur: errorless transfer of a discrimination has advantages over procedures involving trial and error. If an error occurs once, it tends to occur many times, even though it"s (cid:271)ei(cid:374)g extinguished. The nonreinforcement that occurs when errors are being extinguished often produces emotional side effects (ex. tantrums, aggressive behaviour, attempts to escape from the situation)
