Study Notes

Instrumental Conditioning: Introduction

Instrumental conditioning involves learning where a stimulus is a result or consequence of a behavior.
The behavior is necessary to produce a desired outcome.
Instrumental behavior arises because it has previously been effective in producing certain consequences.

Instrumental Conditioning: Thorndike's Findings

The "law of effect" states that if a response in the presence of a stimulus is followed by a satisfying event, the association between the stimulus and response strengthens.
If the response is followed by an undesirable event, the association weakens.
Thorndike's experiments used animal boxes to study learning through trial and error.
His experiments distinguished between discrete trials and free-operant trials.

Modern Instrumental Conditioning: Discrete-Trial Procedures

Willard Stanton Small conducted research similar to Thorndike's, using animal boxes to study instrumental learning.
Training trials began with placing the animal in an apparatus followed by removing it after the instrumental response.
Mazes were used to measure running speed and latency.

Modern Instrumental Conditioning: Free-Operant Procedures

B.F. Skinner developed free-operant procedures which allowed animals to repeat an instrumental response without constraint.
These procedures are used to study behavior continuously.
An example of an operant response is a lever press.
Operant responses are defined in how they operate on the environment.
Any response needed to yield a desired outcome is an instrumental response.

Instrumental Conditioning Procedures: Magazine Training and Shaping

Magazine training teaches the animal to associate a stimulus (e.g., a sound) with food delivery.
Shaping involves progressively rewarding closer approximations of the desired behavior until the desired response is achieved.
Successful shaping clarifies the desired response and divides the progression from the starting point to the goal into appropriate training phases, these are successive approximations.

Instrumental Conditioning Procedures: Positive Reinforcement vs. Positive Punishment

Positive reinforcement: A response produces a pleasant stimulus.
Positive punishment: A response produces an unpleasant stimulus.
Positive reinforcement increases the rate of a response, whereas positive punishment decreases it.
Examples provided include being rewarded for studying versus a punishment for not studying.

Instrumental Conditioning Procedures: Negative Reinforcement vs. Negative Punishment

Negative reinforcement: A response eliminates or prevents an unpleasant stimulus.
Negative punishment (omission training): A response eliminates or prevents a pleasant stimulus
Negative reinforcement increases the response rate and Negative punishment decreases it.

Instrumental Response: Variability

Participants can be rewarded for variations in their responses which encourage creativity
Uniformity and stereotypy aren't inevitable outcomes of instrumental responses.
Variability can be encouraged by using reinforcement structures.

Constraints on Instrumental Conditioning: Belongingness

Responses are more likely to be learned if they belong with the reinforcer based on evolutionary history
Examples include opening a latch, pulling a string, or manipulating objects to release confinement.
Instinctive drift refers to instinctive behaviours interfering with the learned response

Instrumental Reinforcer: Response-Reinforcer Relation

The quality, quantity, and previous reinforcement are important in instrumental conditioning.
Getting immediate reinforcement after a behavior is more effective.
Reinforcer's relationship to the response, and the time between is critical.
Behavioral contrast occurs when a small reward might be considered poor after a strong reward.

Instrumental Reinforcer: Delay of Reinforcement

Delay in reinforcement reduces the effectiveness of the response-reinforcer association.
Immediate reinforcement results in more learning than delayed reinforcment.

Superstition

Superstitious behaviors are associated with accidental reinforcement.
Terminal responses appear near the time of a reinforcement occurrence.
Temporal contiguity (the time proximity between a response and a reinforcer) is a critical factor in instrumental conditioning.
Interim responses occur in the middle interval between reinforcement events.

Learned Helplessness

Learning a lack of control over a negative stimulus can impede future learning.
Animals exposed to inescapable shock perform poor in subsequent learning trials.
The learned helplessness effect occurs due unpredictable and uncontrollable negative stimuli.
The activity deficit hypothesis involves decreased activity as a response to inescapable shocks which leads to limited learning.
