Lecture 2: Pos Rft & Extinction Flashcards
(27 cards)
Learning the relationship between an action and a response
Associative learning
How is classical conditioning different from instrumental conditioning?
CC is paired with a different stimulus
Refers to a function as an event
Reinforcement
Positive contingency: response results in outcome: reward
Appetitive. Response increases
Positive contingency: response results in outcome: punishment
Aversive. Response decreases
Negative contingency: response prevents outcome: omission
Appetitive. Response decreases
Negative contingency: response prevents outcome: negative Rft (e.g. Avoidance)
Aversive. Response increases
Refers to a situation in which a stimulus reinforcers a behavior after it has been associated with a primary reinforcer whereas primary reinforcers occurs naturally and do not need to be learned
Secondary Rft
Example of __________ reinforcement includes waters food, sleep, and air
Primary Rft
An example of ___________ reinforcement is money
Secondary Rft
What are the 2 factors that affect instrumental conditioning?
- Temporal contiguity
2. Contingency
Small/ no interval produces stronger learning in all cases of instrumental and classical conditioning
Temporal contiguity
Statistical relationship between a response and a reinforcer
Contingency
Instrumental conditioning is also known as
Operant conditioning
Reinforces a behavior to achieve a certain goal
Shaping
Complex behavior can be thought as a simple response. What involves shaping a sequence of responses. e.g. Language acquisition.
Response chaining
Involves secondary reinforcement, partial reinforcement, desirable for practical reasons
Schedules of Rft
Mean Rft is derived once every 5 responses
Fixed-Ratio
Mean Rft is delivered on average every 5 responses
Variable-Ratio
Mean Rft delivered on the first response after 5 seconds has elapsed since last Rft
Fixed-Interval
Rft delivered on the first response after a variable time has elapsed since last Rft
Variable-Interval
Elicits rapid responding
Ratio schedules
Post Rft pause
Fixed Ratio
You get rapid responding
Variable Ratio
