In Walter Mischel's early experiments with children and self-regulation, the children who were more effective at self-regulation were found to be more successful later in life. Why might this be the case?

A. Because these children were better at self-control, they were unlikely to engage in extreme or pathological behaviors.

B. Higher ability to self-regulate was found in Mischel's experiments to be correlated with higher IQ scores.

C. Because these children were better at self-control, they could better control impulses and delay gratification later in life.

D. Self-regulation has consistently been correlated with low anxiety and high extroversion, which are two traits that predict success.
