In modeling experiments,the degree of modeling increases as the _____.

A) similarity between the model and the subject increases
B) self-confidence and self-esteem of the observer increases
C) complexity of behavior displayed by the model increases
D) age of the model and the subject increases

The degree of modeling refers to the extent to which a person imitates the behavior of a model. As the similarity between the model and the subject increases, the degree of modeling also increases. This means that the observer is more likely to imitate the behavior of a model who is similar to themselves.
