Answer:
dispositional attribution
Step-by-step explanation:
Richard is using dispositional attribution. Dispositional attribution is “Citing a person's qualities as the reasons for his or her actions or experiences.” Richard is attributing his good academics because of the hard work he puts into his studies. No one else is responsible for his schoolwork but himself, so it is truly the result of his efforts. He believes he is a “take-charge kind of person” because the work he has put into school was his own effort and he had to take charge of the workload and responsibilities of being a student.
