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.

Reinforcement wants to cause an increase in a behaviour

Positive Reinforcement Negative Reinforcement

You encourage the child (positive stimulus) Mother's nagging goes away (takes away a negative stimulus)

Reinforcement wants to cause a decrease in a behaviour

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