Behavioural Modification

Behavioural Modification is a therapeutic and treatment approach designed to change a undesirable negative behaviour. By using a system of positive or negative consequences, an individual learns the correct set of responses for any given stimulus.

The goal of reinforcement is to cause an increase in a behaviour.

Positive Reinforcement Child does dishes You encourage/praise the child (positive stimulus)
Negative Reinforcement Child does dishes to avoid nagging by mother Mother's nagging goes away (takes away a negative stimulus)

The goal of punishment is to cause a decrease in a behaviour.

Punishment

Negative Punishment Child bullies another child You take away the child's toy (reinforcing stimulus removed)
