Imagine That Researchers Interested in the Possible Bidirectional Influence of Children's

Imagine that researchers interested in the possible bidirectional influence of children's aggression and parental use of punitive discipline examined these two variables when a group of children was at each of three ages: 4 years old, 8 years old, and 12 years old. Which of the following statements would be the best support for the bidirectional influence of these variables?

A) Greater punitive discipline at age 4 was associated with greater punitive discipline at age 8, which was associated with greater aggression at age 12.
B) Greater aggression at age 4 was associated with greater punitive discipline at age 8, which was associated with greater aggression at age 12.
C) Greater aggression at age 4 was associated with greater aggression at age 8, which was associated with greater punitive discipline at age 12.
D) Less punitive discipline at age 4 was associated with greater aggression at age 8, which was associated with greater aggression at age 12.
