Questions and Answers

Unlike classical conditioning, which tends to focus on or involuntary behaviours (largely controlled by stimuli that or come before the response), there is another type of conditioning, which focuses on voluntary or behaviours. The organism ‘operates’ on the environment and does not just react to stimuli.

What are the basic processes of operant conditioning?

Acquisition and Shaping = Acquisition is the initial stage of learning a new pattern of responding. It is usually a gradual process. If the operant response (bar-press) of a hungry rat is followed by a reinforcer (food pellet) then the rat is more likely to press the bar again. Shaping is needed if the organism does not, on its own, emit the desired response (Burton, Westen, & Kowalski, 2019, p.387). This procedure involves no longer following the operant response (bar-press) with a reinforcer (food pellet). This results in the gradual weakening and disappearance of the response. Often the number of responses increases initially, and then gradually decreases. (Burton, Westen, & Kowalski, 2019, pp.379-380). = Extinction Resistance to extinction = This occurs if the organism continues to make responses after reinforcement has been stopped. Spontaneous recovery = After a session of extinction, and time away from the Skinner box, the ‘extinguished’ bar-pressing response may reappear. Signup and view all the answers

What are the basic processes of operant conditioning?

Generalisation = This process refers to responses being made in the presence of stimuli that are similar to the original discriminative stimulus used in conditioning. This is the opposite of generalisation. It involves an organism’s lack of response to stimuli, which are similar to the original discriminative stimulus used in conditioning. = Discrimination Delayed reinforcement = A favourable or positive outcome is more likely to strengthen a response if it immediately follows the response. Conditioning proceeds slowly if there is a delay between a response and the delivery of the reinforcer. Conditioned reinforcement = Through repeated pairings with a primary reinforcer (unconditioned), a secondary reinforcer (conditioned) can also act as a reinforcer. Primary reinforcers satisfy biological needs (e.g., food for a hungry organism, or water for a thirsty one). Secondary reinforcers depend on learning- for humans include money, tokens, material possessions etc. Signup and view all the answers

Study Notes

Operant Conditioning

Focuses on voluntary or learned behaviours, unlike classical conditioning which focuses on involuntary behaviours
The organism actively operates on the environment and doesn't just react to stimuli

Definition of Operant Conditioning

A form of learning in which responses come to be controlled by their consequences (Weiten, 2007)

The 3-Term Contingency

The 3-term contingency consists of:
- Discriminative stimulus (the signal for the organism to respond)
- Response (the behaviour emitted by the organism)
- Consequence (the outcome or result of the response)

Reinforcers and Punishers

Reinforcers: events that increase the tendency to make a response
Punishers: events that decrease the tendency to make a response

Consequences of Behaviour

Reinforcement: an event following a response that increases the tendency to make that response
Punishment: an event following a response that decreases the tendency to make that response

Basic Processes of Operant Conditioning

Reinforcement: increases the frequency of behaviour
Punishment: decreases the frequency of behaviour
Extinction: the absence of reinforcement leading to a decrease in frequency of behaviour

Schedules of Reinforcement

Fixed-Ratio (FR) Schedule

Reinforcer is given after a fixed number of non-reinforced responses
Every nth response is reinforced

Variable-Ratio (VR) Schedule

Reinforcer is given after a variable number of non-reinforced responses
Every nth response is reinforced, but the exact number of responses needed for reinforcement varies

Fixed-Interval (FI) Schedule

First response that occurs after a fixed time interval has elapsed is reinforced

Variable-Interval (VI) Schedule

First response that occurs after a variable time interval has elapsed is reinforced
Interval length varies around a predetermined average
