Unit 3 Flashcards
Antecedent
A stimulus or event that precedes the target behavior
Discriminative Stimulus (SD)
The Stimulus that is signals the availability of reinforcement
Generalization
The process in which the behavior occurs in response to an antecedent that is similar in some way to the SD.
S-Delta (SΔ)
A stimulus that is present when a behavior is not reinforced. In discrimination training,, the behavior is reinforced if it occurs in the presence of the SD but not in the presence of the S.
Stimulus Class
- A group of stimuli that all have the same functional effect on a particular behavior
- Each stimulus in a class may function as a SD for a particular behavior
Stimulus Control
- The outcome of Stimulus Discrimination Training
- A particular behavior is more likely to occur in the presence of a particular SD because the behavior has only been reinforced when the SD is present
- The SD has stimulus control over the behavior
Stimulus Discrimination Training
- A.K.A. Discrimination Training
- A process in which a behavior is reinforced when the SD is present, and extinguished when the SΔ is present
- As a result, the behavior is more likely to occur only when the SD is present
Three Term Contingency
- The antecedent that is present when the behavior occurs,
- The Behavior The occurs
- The Reinforcing Consequence
A.K.A. The Contingency of Reinforcement
Operant Behavior
- Focuses on Consequences
- Antecedents precede Operant Behavior
A-B-C’s of Operant Behavior
Antecedent
Behavior
Consequence
SD Vs. Establishing Operation
SD is a stimulus that present when reinforcement is available
EO makes reinforcement more potent
Extrastimulus Prompt
A.K.A. Additional Stimuli
A type of stimulus prompt in which a stimulus is added to help a person make a correct discrimination
Fading
The gradual removal of prompts as the behavior continues to occur in the presence of the SD
Gestural Prompt
A physical movement or gesture of another person that leads to the correct behavior in the the presence of the SD
Learning Trial
The sequence of:
- presenting the SD
- prompting the response
- Providing a reinforcer
Modeling Prompt
- A type of prompt in which the trainer demonstrates the target behavior for the learner
- Works best in conjunction with instructions, or in situations which the learner has an opportunity to rehearse the behavior
Physical (Guidance) Prompting
- A type of prompt in which the trainer physically assists the learner to engage in the correct behavior
- “hand-over-hand”
Prompt
A prompt is used to increase the likelihood that a person will engage in the correct behavior at the correct time
