Which theory views the family as a functional unit for problem-solving and decision-making?

Family Systems Theory is the correct choice because it posits that families operate as interconnected and interdependent units, where individual behaviors and decisions affect the entire family system. This theory emphasizes the importance of the relationships and dynamics within the family, asserting that each member plays a role in problem-solving and decision-making processes. It recognizes that patterns of interaction, communication, and emotional ties among family members can significantly impact how the family navigates challenges and crises.

The focus on the family as a functional unit allows for a comprehensive understanding of how collective decision-making occurs, highlighting that issues are often best understood in the context of family dynamics rather than in isolation. This holistic approach fosters the idea that improving communication and understanding within the family can lead to more effective solutions to problems.

In contrast, the other theories presented do not specifically address the family unit as a functional entity for problem-solving. Behaviorism emphasizes observable behaviors and the influence of the environment on learning, while Cognitive Development Theory focuses on individual cognitive processes rather than familial relationships. Social Constructivism centers on the social context of learning and knowledge construction, but it doesn't specifically relate to the family as a decision-making unit.
