Which of the following best describes the relationship emphasized by biosocial theory?

• A. Unidirectional from biology to behavior.
• B. Bidirectional influence between biology and social context.
• C. Unidirectional from culture to biology.
• D. Random correlation.

Answer: (B)

Biopsocial theory emphasizes that biology and the social environment influence each other in a continuous, reciprocal loop. Biological factors like genetics, hormones, and brain development create certain tendencies or responses, but those tendencies are shaped and modified by the social context—family dynamics, parenting, stress, culture, and available resources. For example, a child who is biologically predisposed to high reactivity may trigger more protective or controlling parenting, which then affects the child’s stress physiology and brain development over time. At the same time, supportive, enriching environments can modulate how those biological tendencies express themselves. This mutual influence explains development as an ongoing interplay, rather than a one-way effect from biology to behavior, from culture to biology, or a random correlation.
