Which of the following perspectives is most relevant to the study?

The cognitive perspective emphasizes internal mental processes such as thinking, memory, and problem-solving. While cognitive factors may play a role in how stress is perceived or managed, this perspective does not directly address the social transmission of affect, which is the core focus of the study regarding mothers and infants.

The psychoanalytic perspective centers on unconscious motivations and early childhood experiences in shaping behavior. Although it explores emotional development and attachment, it does not specifically account for the social dynamics involved in affect contagion, making it less relevant to the study's findings on stress transmission.

The behavioral perspective examines observable behaviors and the effects of the environment on actions. While it can explain how behaviors are learned and reinforced, it lacks an emphasis on social interactions and emotional exchanges that are crucial for understanding how stress is communicated between mothers and infants.

The Gestalt perspective focuses on perception and the idea that the whole is greater than the sum of its parts. Although it values the context of experiences, it does not directly address the social processes involved in affect contagion, which are central to the study's conclusions about emotional transmission.
