Sixteen-year-old Gregory wrecked his parent's car on a snowy day. His parents assumed that the accident was caused by his carelessness and lack of concern for their car. Gregory's parents' assumption illustrates

A dis-positional attribution

Explanation:

A dis-positional attribution's the attribution in which the cause and responsibility are assigned to the external factor rather than the internal factor for the disposition of characteristic. It is also called internal attribution. In this phenomenon, people used an internal disposition to explain the behavior of others rather than own behavior.

Thus here in the above statement, sixteen-year-old Gregory wrecked his parent's car and his parents assumed that the accident happened due to his carelessness and due to lack of concern about their car that reflects dis-positional attribution.
