Document Summary
Shaping happens naturally babbling to imitating to talking, for example. Shaping: used to develop a target behaviour that a person does not currently exhibit. Differential reinforcement: involves the basic principles of reinforcement and extinction. One particular behaviour is reinforced and all other behaviours are not reinforced in a particular situation. As result, the behaviour that is reinforced increases and the behaviours that are not reinforced decrease through extinction. To begin shaping: identify an existing behaviour that is an approximation of the target behaviour = starting behaviours or first approximation. You reinforce this behaviour = person exhibits this behaviour more often. You then stop reinforcing this behaviour and, as a part of extinction burst, novel behaviours occur. You pick the behaviour that is the closer approximation to the target behaviour = person exhibits this behaviour more often and the previous behaviour less often. This process of differential reinforcement continues until the person finally exhibits the target behaviour.
