1
Q

What is reinforcement schedule?

A

A plan of how often and when reinforcement will be provided

2
Q

What is behaviour modification?

A

The use of operant conditioning techniques to change the frequency of desired behaviours, for example in therapeutic seetings

3
Q

What is shaping?

A

A process of modifying behaviour by reinforcing successive approximations to a desired behaviour

4
Q

What is continuous reinforcement?

A

A behaviour is said to be continuously reinforced when the reinforcer always follows a behaviour. For example, we might pay a child every time they do the washing up.

5
Q

What are the effects of continuous reinforcement?

A

Rapid change in behaviour but effects tend not to last

6
Q

What is partial reinforcement?

A

Reinforcement is irregular.

7
Q

What is a fixed ratio reinforcement schedule?

A

A reinforcer is given after a specified number of behaviours, for example we pay a child every seventh time they do the washing up

8
Q

What is variable ratio reinforcement schedule?

A

A reinforcer is given after an unpredictable number of behaviours that varies around a mean value.

9
Q

What do variatial ratio schedules lead to?

A

Lead to behaviour change that is difficult to extinguish

10
Q

What is a fixed interval reinforcement schedule?

A

The time between reinforcers is kept constant. E.g. paying a child at the end of the time interval if he has washed up one or more times during that interval

11
Q

What is variable interval reinforcement schedule?

A

The time between reinforcers is varied around a mean length of time. As with fixed interval, only one behaviour per time period is needed for reinforcement. So a child is again paid at the end of the time period if he washed up one or more times during the interval but the interval varies in length
