The greater convergence, there is a decrease in two-point discrimination. Which option correctly completes this statement?

• A. Increase (more acute)
• B. No change
• C. Fluctuation
• D. Decrease (less acute)

Answer: (D)

Greater convergence of sensory inputs reduces spatial precision. When many receptors feed into a single neuron, receptive fields become larger and signals from nearby points blend together, making it harder to tell two separate points apart. So as convergence increases, two-point discrimination becomes less acute. The correct completion is a decrease (less acute). If convergence were low, two-point discrimination would be more acute; options suggesting increase or no change don’t align with this relationship.
