Document Summary

Types of stimuli: discriminative stimulus (sd, when the consequence only occurs in the presence of the stimulus, stimuli in the environment that increase the chance of the behaviour to occur, ex. If this stimulus is present, then response will not be reinforced: when the consequence never occurs in the presence of the stimulus, ex. Stimulus discrimination training: procedure of reinforcing a response in the presence of an sd, and extinguish that response in the presence of s . Involves successive steps to work towards the desired stimuli/context, using prompts and reinforcement: similar to scaffolding, example. Errorless learning: use of a fading procedure to establish a stimulus discrimination so that no errors occur. Shaping: the development of a new behaviour by reinforcement of successive approximations, and extinguishing earlier approximations. Shaping pacing: reinforce an approximation several times before proceeding, avoid over reinforcing any approximation. If you lose the behaviour, return to previous approximation, reinforce, then add a smaller step.
