Final answer:
The Sociocultural Approach focuses on how societal norms and cultural contexts influence individual behavior, differentiating it from other perspectives that may focus on biological or individual psychological factors.
Step-by-step explanation:
The psychological perspective that argues understanding a person's behavior requires knowing about the context in which behavior occurs is the Sociocultural Approach. This approach emphasizes the influence of societal norms, cultural practices, and interpersonal relationships in shaping an individual's behaviors and decisions. In contrast to other psychological perspectives that may focus on individual aspects, such as inner drives or biological factors, the sociocultural perspective is concerned with the external influences and how social and cultural contexts impact an individual.
