Answer:
Continuity-discontinuity.
Explanation:
Dr. Fletcher's research to determine whether adult criminals were rule-breakers throughout their childhood or not is most concerned with the issue of continuity-discontinuity in human development. Continuity and discontinuity are theories of human developmental psychology. Continuity states that adult behavior can be traced back to childhood behavior. On the contrary, the discontinuity theory states that changes occur suddenly in human behavior.
