Chapter 7 Flashcards
Is the associative structure of instrumental conditioning molar or molecular approach?
Molecular
What is the SR association called?
Habit (stimuli-response): association between contextual stimuli and instrumental response; after a while it becomes an habit, O is not needed anymore
What is the SO association called?
Pavlovian conditioning (stimulus/outcome): stimulus triggers the memory of the outcome: puts the organism in a motivational state to perform the instrumental response.
What is the insensive salience theory?
when someone is exposed to the stimulus associated w taken the drug, it triggers the emotional state usually triggered by the outcome (being high on the drug), leading to intense cravings (mostly associated with drug addiction patterns)
What were the 2 reasons that Clark Hull and Kenneth Spence established for the increase of RO
1- Stimuli evokes the RO through the SR associations (skinnerian view)
2-RO is also triggered by the SO association (pavlovian view)
Who was major in the discovery of SR associations?
BF Skinner
Who was major in the discovery of SO associations?
Pavlov
What is the two-process theory?
Both pavlovian (classical) and instrumental conditioning are involved in the development of an instrumental response
What is the Pavlovian instrumental transfer experiment (steps)?
Phase 1 and 2: classical (SO) ans instrumental (RO) conditioning
• 2 phases can be interchanged (1 before 2 or vice versa) and can happen in different training chambers
Phase 3: transfer test - presenting Pavlovian CS during performance of the instrumental response (how much lever pressing happens with and without the tone)
The instrumental response will be performed more when the pavlovian CS is also present (puts the organism in a motivational state)
What is the Pavlovian instrumental transfer experiment trying to demonstrate?
It determines how an independently established Pavlovian CS transfers to influence or motivate instrumental responding (that SO association also has an influence on responding rate)
Who was major in developing the RO association?
Skinner
What is the RO association?
Response-Outcome: A response leads to an outcome, which is a reinforcer for the stimulus (instrumental/operant conditioning)
How can we test the importance of the outcome in relation to the response?
With the reinforcer devaluation experiment
What is the reinforcer devaluation experiment?
If reinforcer devaluation disrupts instrumental behavior, this shows that the memory of the outcome (O) was involved in motivating the instrumental behavior.(ex experiment with smokers)
Which behavioural mechanisms predominate in free-opreant situations (when you have a choice)?
RO mechanisms
