Study Notes

Instrumental Conditioning: Foundations

Instrumental conditioning involves training behaviors to achieve a goal. Obtaining a reinforcer (e.g., a reward) depends on the response occurring.
Early instrumental conditioning research, pioneered by E. L. Thorndike, focused on animal learning using puzzle boxes. Animals learned to perform required actions (responses) to escape the box and obtain a reward (food). Thorndike's work led to the "law of effect," stating rewarded responses are strengthened.
Modern approaches to instrumental conditioning use discrete-trial procedures (e.g., mazes) or free-operant procedures.
Discrete-trial procedures involve manipulating a specific response to obtain a reward, while free-operant procedures permit multiple responses and allow the animal to learn at its own pace.
Magazine training is a preliminary instrumental learning step, where a neutral stimulus is paired with a reinforcer until the stimulus evokes the approach response. This neutral stimulus eventually becomes a conditioned stimulus.

Instrumental Conditioning Procedures

Positive Reinforcement: A desirable stimulus follows a desired response, increasing the likelihood of the response occurring. (e.g., a child gets a cookie for cleaning their room)
Punishment (Positive Punishment): An aversive stimulus following a response, which decreases the likelihood of the response recurring. (e.g., a child gets a time-out for bad behavior)
Negative Reinforcement (Escape or Avoidance): An aversive stimulus is removed following a response, increasing the likelihood of the response occurring. (e.g., putting on a seatbelt to stop the car alarm)
Omission Training (Negative Punishment): A desirable stimulus is removed following a response, decreasing the likelihood of the response. (e.g., losing privileges for breaking a rule)

Fundamental Elements of Instrumental Conditioning

Instrumental Response: The behavior that is performed to achieve a desired outcome.
Reinforcer: The stimulus that strengthens the instrumental response. The reinforcer can be positive (desirable stimulus) or negative (removal of an undesirable stimulus).
Response-Reinforcer Relation: The contingency between the response and the reinforcer determines how effectively the response is learned. A strong contingency means the reinforcer is more likely to occur following a specific response.

Modern Approaches

Thorndike used puzzle boxes.
Today, mazes (e.g., runway mazes, T mazes) are commonly used for discrete trial learning and free-operant procedures.
A free-operant procedure allows repeated responses, whereas a discrete trial procedure has a set time frame.

Shaping

Shaping involves reinforcing successive approximations of a target behavior, gradually guiding the animal toward the desired response.
This method is used to teach complex behaviors.
Can determine how effective a reinforcer is.

Response Rate

Response rate refers to the frequency of a response over a specific time period.

Instrumental Conditioning and Reinforcement

Factors influencing reinforcement include the quality and quantity of a reinforcer, along with prior experience and expectations.
Quantity and quality of the reinforcer considerably affect the success of positive reinforcement. A larger, more desirable reinforcer typically leads to a more effective reinforcement outcome.

Response-Reinforcer Contingency

Temporal relation factors influence the effectiveness of instrumental learning.
Immediate reinforcement is more effective than delayed reinforcement in producing a response.
Other factors, including safety signals, affect the efficacy of instrumental learning.

Learned Helplessness

Exposure to uncontrollable aversive stimulation can negatively affect learning and performance in subsequent tasks.
The learned helplessness effect has implications for human mental health, such as PTSD and depression.
