L2: Instrumental Conditioning Flashcards
What is Instrumental Conditioning also known as?
Operant Conditioning
What are the two main types of associative learning?
Classical Conditioning and Instrumental Conditioning
Describe Classical Conditioning
- an organism learns to associate a neutral stimulus (conditioned stimulus) with an unconditioned stimulus that naturally elicits a reflex response.
- over time, the neutral stimulus alone can trigger the reflex response
How is Instrumental Conditioning different from Classical Conditioning?
- Instrumental Conditioning involves learning how to control the environment to acquire desirable outcomes/avoid undesirable ones.
- the animal’s behavior is instrumental in obtaining what it wants
- unlike Classical Conditioning, which is reflexive, Instrumental Conditioning focuses on voluntary behaviors and their consequences
Define Reinforcement in the context of Instrumental Conditioning
- refers to the consequences of behavior that increase the likelihood of that behavior being repeated
- a reinforcer is something the animal wants, and it is contingent on the organism’s behavior
How does a reinforcer differ from a reward?
- a consequence that follows a behaviour and increases the likelihood of that behaviour being repeated.
- It is contingent on the behaviour.
- whereas, a reward is something given for a worthy accomplishment, but it may not be directly contingent on the specific behaviour
According to Edward Thorndike’s Law of Effect, what happens to behaviors that lead to satisfying outcomes or unsatisfying outcomes?
- Behaviors that lead to satisfying outcomes will be strengthened (stamped in)
- while behaviors that lead to unsatisfying outcomes will be weakened (stamped out)
Describe B.F. Skinner’s contribution to Instrumental Conditioning
- B.F. Skinner developed the concept of Operant Conditioning, which involves learning through the consequences of behaviour
- emphasized that the consequences of behaviour affect the probability of its recurrence in the future
- Skinner’s experiments with pigeons & rats in controlled environments (Skinner box) revealed the importance of punishment & reinforcement in shaping behaviour
What is shaping in the context of Instrumental Conditioning?
- refers to the reinforcement of successive approximations to a final desired behavior
- involves reinforcing behaviours that are closer & closer to the target behavior until the desired behavior is achieved
What is the purpose of discrimination training in Instrumental Conditioning?
- discrimination training curbs generalization and helps organisms differentiate between stimuli that predict reinforcement and those that don’t
- e.g, a child learning to pet a friendly dog but not an unfamiliar aggressive dog demonstrates discrimination training
What are Conditioned Reinforcers in Instrumental Conditioning?
- secondary reinforcers that gain their reinforcing properties through classical conditioning
- they increase the generalizability of instrumental conditioning and contribute to maintaining behaviors.
What factors decrease the likelihood of behavior in Instrumental Conditioning?
- punishment, which must be immediate, inevitable, and severe
- punishment is not effective in the long run, and it may lead to undesired side effects such as fear and aggression
What are Schedules of Reinforcement in Instrumental Conditioning?
- refer to the patterns in which reinforcers are delivered following a behaviour.
- Examples include Variable Ratio (e.g., slot machines) and Fixed Interval (e.g., snail mail delivery)
What is the Premack Principle, and how was it tested in an experiment by David Premack?
- states that if one activity occurs more frequently than another, it can be used to reinforce the less frequent activity
- David Premack tested this principle in an experiment with first-grade children, using manipulator-eater contingencies
According to the Disequilibrium Hypothesis, what makes a specific activity reinforcing or punishing?
- states that any activity can be a reinforcer if a contingency schedule restricts an animal’s access to that activity
- if the activity is below baseline, it can be used to reinforce another activity
- If the activity exceeds the baseline, it becomes a punisher
