Bandura believes self-reinforcement

A) depends on frequent external reinforcement.
B) is particularly effective in children.
C) is like requiring personal standards of behavior and achievement.
D) is not as effective as reinforcement administered by others.

Bandura believes that self-reinforcement is similar to having personal standards of behavior and achievement. It is the ability to reinforce oneself based on one's own internal standards and goals without the need for external reinforcement. Hence, option C is the correct answer. Option A is incorrect because self-reinforcement does not depend on frequent external reinforcement. Option B is incorrect because self-reinforcement is effective across all ages, not just in children. Option D is incorrect because research has shown that self-reinforcement can be just as effective as reinforcement administered by others.
