Schedules of Reinforcement
Rules that state the relationship between a certain behaviour and its consequences, defined in terms of duration or time or number of responses required to present a reinforcer
Continuous Reinforcement Factors (3)
Leads to rapid acquisition of a target behaviour, as well as rapid increase in target behaviour, but is not common in real life situations
Rate of responding
Controlled by how frequently the target behaviour is reinforced, so rich schedules produce higher rater and ratio schedules produce higher rates
Pattern of responding - fixed interval
Acceleration of responding following the post-reinforcement pause, until the delivery of a reinforcer (overall a low rate of response)
Partial Reinforcement Extinction Effect (Who, what)
Humphrey, partial or intermittent reinforcement schedules are more resistant to extinction than continuous reinforcement schedules
In order for behaviour to change, a subject must be able to discriminate the changes in reinforcement contingency (which is harder when intermittent)
Generalisation Decrement Hypothesis
There is decreased responding in a generalisation test when the test stimulus becomes less similar to the training stimulus
Reinforcers decrease in strength over time; incorrect as longer pauses are found with longer fixed ratio schedules
The subject is tired after responding and so pauses to recover after reinforcement; incorrect as subjects often work harder and without pauses
After receiving a reinforcer, the subject realises that they are the furthest away from receiving their next reinforcer; correct with support from multiple schedules research
A subject is presented with two or more different reinforcement schedules one at a time, signaled by different discriminative stimuli
There is a linear relationship between response rate and reinforcer rate for VR schedules, but there is an asymptote for VI schedules, so higher response rates aren't worth the effort
