answers
Stimulus control
Responses are reinforced only in the presence of a specific stimulus
(SD) and not in the presence of other stimuli (SΔ).
Occurs when in the presence of an antecedent stimulus the rate,
latency, duration, or amplitude of a response is altered.
Stimulus Control Examples
- Student always complains to a certain teacher... because they
always provide attention.
- Aggressive in presence of math teacher but not gym teacher
- When you enter a bar with friends, you "speak" a certain
way...certain words and phrases are reinforced.
- Your niece will ask you to do certain activities but not your brother,
because you do them (make up dances, hula hoop, Barbies)
- Get up when alarm goes off versus not (or hear other noises)
Discriminative Stimuli:
• SD - Reinforcement available
• SΔ - Reinforcement is not available
• SDp - Punishment is coming
SD
Reinforcement available
Stimulus Delta SΔ
Reinforcement is not available
SDp
Punishment is coming
Antecedent Stimulus
, The Sd and the Conditioned Stimulus are antecedent stimuli that
evokes the occurrence of behavior.
There is no consequence, Behavior is evoked by an antecedent
stimulus.
Stimulus control of an operant response appears similar to the
control of the respondent behavior by a conditioned stimulus.
Stimulus Generalization
- Stimuli that share similar physical characteristics with the
controlling stimulus evoke the same behavior as the controlling
stimulus.
Stimulus discrimination
- A learned ability to differentiate among similar products
- Different stimulus that don not evoke the response.
- New stimuli that are similar to the controlling stimulus do not
evoke the same response as the controlling stimulus.
Stimulus generalization Gradient
- How much stimulus controls based on distance, latency...
- Shows the degree of stimulus generalization and discrimination via
GRAPH.
- Shows the extend to which response reinforced in one stimulus
condition are emitted in the presence of untrained stimulus.
Faulty Stimulus Control
- The target behavior comes under the restricted control of an
irrelevant antecedent stimulus.
- Stimulus being paired accidentally with a completely different
stimulus.
Ex: Flashcard of a dog with a toilet behind.
Stimulus-Stimulus Pairing
Pairing a non-reinforcing stimulus with a reinforcing stimulus so the
non- reinforcing stimulus becomes reinforcing (transfer of stimulus
control)
Ex:
Child hates being at table and loves Hershey Kisses
