Ch. 7 - Stimulus Control: Discrimination and Generalization Flashcards
What are antecedents?
Stimulus events that precede an operant response.
What are the ABCs of operant behaviour?
Antecedents, behaviour, and consequences.
When can a behaviour be said to be under stimulus control?
When there is an increased probability that the behaviour will occur in the presence of a specific antecedent stimulus or a stimulus from a specific stimulus class.
Why does stimulus control develop?
Because a behaviour was reinforced only in the presence of a particular antecedent stimulus.
What is a discriminative stimulus?
The antecedent stimulus present when a behaviour is reinforced.
What is stimulus discrimination training?
The process of reinforcing a behaviour only when a specific antecedent stimulus is present.
What is S-delta?
Any antecedent stimulus that is present when the behaviour is not reinforced.
What is there result of discrimination training?
The behaviour is more likely to occur when the discriminant stimulus is present and less likely to occur when S-delta is present.
What does the discriminant stimulus not do?
It does not cause the behaviour, nor does it reinforce the behaviour.
What is the three-term contingency?
A process in which the consequence is contingent on the occurrence of the behaviour only in the presence of the specific antecedent stimulus.
What is the notation used to describe the three-term contingency?
SD -> R -> SR/SP
How does extinction relate to the three-term contingency?
When a behaviour is no longer reinforced in a particular situation, the behaviour decreases in the future in that particular circumstance.
What is stimulus generalization?
When a behaviour occurs in the presence of stimuli that are similar in some way to the discriminant stimulus that was present during training.
What is the generalization gradient?
The more similar the generalized stimulus is the to discriminant stimulus, the more likely to behaviour is to occur and vice versa.
What is a stimulus class?
The group of antecedent stimuli that share similar features and have the same functional effect on a particular behaviour.
