Document Summary

Chapter 7: stimulus control discrimination and generalization. Antecedents: stimulus events that precede an operant response: antecedents of behaviours: stimulus events, situations, circumstances that are present when it occurs or were present before the behaviour. Stimulus control develops because a behaviour is reinforced only in the presence of a particular antecedent stimulus. Discriminative stimulus (s^d): antecedent stimulus that is present when a behaviour is reinforced. Stimulus discrimination training: process of reinforcing a behaviour only when a specific antecedent stimulus (s^d) is present. 2 steps in stimulus discrimination training: 1. When the s^d is present, behaviour is reinforced: 2. When any other antecedent stimuli except the s^d are present, behaviour is not reinforced. During discrimination training, any antecedent stimulus that is present when behaviour is not reinforced is called an s-delta. S^d present behaviour more likely to occur but does not cause behaviour to occur; s-delta present behaviour less likely to occur.
