Study Notes

Skinner Box and Instrumental Conditioning

Skinner used a "Skinner box" to study the relationship between events in instrumental conditioning.
The box contained a lever and a food tray.
A rat was placed in the box and allowed to explore.
When the rat pressed the lever, a food pellet was dispensed.
Pressing the lever was the "operant response" and the food was the "reinforcer."
The rat learned to associate the lever press with food, resulting in an increased rate of lever presses.
Similar experiments were conducted on pigeons, and negative reinforcement and avoidance behavior were studied in dogs.

Basic Components of Operant Conditioning

Operant: A response that has an effect on the environment.
Reinforcer: An event that increases the probability of an operant behavior occurring again.
Reinforcers can be positive or negative and increase the likelihood of a previous response happening again.

Types of Reinforcement

Positive Reinforcement: Strengthens a response by presenting a positive stimulus after a response.
- Examples: Food for animals, attention, approval, and money for people.
Negative Reinforcement: Strengthens a response by removing or reducing an unpleasant stimulus.
- Examples: Reducing or switching off an electric shock for an animal.

Primary and Secondary Reinforcement

Primary Reinforcement: An innately reinforcing stimulus that satisfies a biological need.
- Examples: Food for a hungry person, warmth for a cold person.
Secondary Reinforcement: A learned reinforcer that gets its power through association with primary reinforcers.
- Examples: Money, good grades, praise, and a pleasant tone of voice.

Stimulus Discrimination

Organisms learn when to make a previously successful response and when not to.
They do this by learning to recognize signals that indicate whether a reinforcer will or will not be available.
These signals are called discrimination stimuli.

Avoidance Conditioning

Occurs when an organism responds to a signal to avoid exposure to an aversive stimulus.
Examples: Going to school or work to avoid losing a job, stopping at a red light to avoid a fine.

Escape Conditioning

The organism learns to make a response to end an aversive stimulus.
Examples: A dog learning to jump over a bar to escape an electric shock.

Stimulus Generalization

Organisms often perform a response in the presence of a stimulus that is similar to one that was previously reinforced.

Difference between Operant and Classical Conditioning

Both types of conditioning involve acquisition, extinction, spontaneous recovery, generalization, and discrimination.
However, there are key differences:

Classical Conditioning

Involves respondent behavior, which is elicited by a stimulus.
The controlling stimulus comes before the response.
Reinforcement depends on the presented conditioned stimulus, regardless of the animal's behavior.

Operant Conditioning

Involves operant behavior, which is voluntary action.
The controlling stimulus comes before the response.
Reinforcement depends on the appropriate response.
In classical conditioning, the unconditioned stimulus (e.g., food) is presented regardless of the animal's behavior.

Extinction & Spontaneous Recovery

Extinction: The weakening of the conditioned response in the absence of the unconditioned stimulus (in classical conditioning).
- Without association with the UCS, the CS loses its power to elicit the CR.
Spontaneous Recovery: The reappearance of a previously extinguished conditioned response after a period of time.

Operant Conditioning: The Work of B.F. Skinner

Operant conditioning is a type of learning in which the consequences of behavior influence future behavior.
Skinner extended Thorndike's ideas, emphasizing how organisms learn a response by operating on the environment.
He identified the basic elements and laws of operant conditioning.
He was the leading figure in this field and his work led to the development of behavior modification techniques.
Skinner conducted experiments on pigeons, rats, and human beings.
He defined "operant" as a response or class of responses that have a consistent effect on the environment.
He distinguished operants from "respondents," which are behaviors elicited by stimuli.
He argued that responses are "emitted" by the organism, meaning they are produced spontaneously without a readily identifiable stimulus.
