Operant conditioning (Reinforcement and behaviour modifications) Flashcards
Define reinforcement schedules
plan of how often and when reinforcement will be provided
Schedules of reinforcement:
What is continuous reinforcement? + example
when the reinforcer always follows a behaviour
example: paying a child every time he washes up.
Schedules of reinforcement:
What is partial reinfrocement
Irregular reinforcement, can come in 2 forms
Schedules of reinforcement:
What are the 2 types of partial reinforcement
Fixed and variable ratio reinforcement schedule
or
Fixed and variable interval reinforcement schedule
Schedules of reinforcement:
What is the difference between the ratio and interval reinforcement schedules
Ratio reinforcement deals with how many times a behaviour must happen before reinforcement.
Interval reinforcement deals with how much time will pass before the reinforcement
Schedules of reinforcement:
What is fixed ratio reinforcement schedule
Reinforcer is given after behaviour appeared a specific number of times
Schedules of reinforcement:
What is variable ratio reinforcement schedule
A reinforcer is given after an unpredictable number of behaviours that varies around a mean value.
Schedules of reinforcement:
What is a fixed interval reinforcement schedule
Time between reinforcers is kept constant
Schedules of reinforcement:
What is variable interval reinforcement
time between reinforcers is varied around a mean length of time.
Behaviour modification:
define behaviour modifications
The use of operant conditioning to change the frequency of desired behaviour.
Behaviour modification:
Example of when behaviour modification happened in sport psychology
Ford et al measured head-impact in helmet sensors of american football players and used mentoring to provide reinforcement to the high risk players.
Behaviour modification:
Results of Ford et al
mean impact intensity dropped by 3.9% and by 4.7% overall on the top of the head.
Modified behaviour improved safety.
Behaviour modification:
Define shaping
When behaviour is only reinforced when theres approximations of the desired behaviour
Behaviour modification:
Why is shaping used
To encourage complex behaviours, like learning a language.
Strength of reinforcement schedules
They are supported by many studies conducted on humans and animals
