Biological Approach

Biological reductionism

Section A Model Answer

Question

Explain Biological Reductionism with reference to one human behavior. [4]

Model Answer

Biological reductionism is a theoretical approach that explains complex human behaviors by breaking them down into their simplest biological parts, such as a single gene, hormone, or neurotransmitter. While this allows for scientific precision and the development of medical treatments, it may oversimplify behavior by ignoring the interaction between biology and the social or cognitive context. For example, explaining aggression solely through testosterone levels is a reductionist approach. While high testosterone is associated with increased amygdala sensitivity, this view is reductionist because it reduces a complex social behavior to a single biological variable, ignoring how social context or cognitive appraisal can moderate an aggressive response. This demonstrates the limitations of reductionist explanations, which may fail to account for the holistic nature of human behavior.

Section B Model Answer

Scenario

The Master Scenario: "The Workspace Study" A university department designs a new "collaborative innovation hub" to improve student performance. The room features open seating, bright lighting, and digital whiteboards. Researchers observe that when students work in this specific environment, their problem-solving speed increases by 20%. However, they also notice that students from different cultural backgrounds use the space differently, and those who feel "out of place" in the high-tech setting often perform worse than they did in traditional libraries.

Question

Explain how biological reductionism might limit our understanding of the workspace study. [6]

Model Answer

Biological reductionism is the assumption that complex human behaviors can be fully explained by breaking them down into their smallest biological components, often ignoring emergent properties such as cultural identity. While a reductionist approach might explain the 20% speed increase through glutamate levels or synaptic strengthening, it ignores sociocultural factors like prior enculturation into library norms or a sense of belonging. This demonstrates the limitation of biological reductionism because, by reducing the workspace effect to neurotransmission alone, it fails to account for the sociocultural variables that the scenario identifies as crucial to the students' success.
