The social cognitive approach to personality.
Explanation:
<u>The Social Cognitive approach to personality was theorized by </u><u>Albert Bandura. </u>

After observing the person will imitate those attributes whether positive or negative. The person will be rewarded/punished then accordingly what he imitates.
