Bloch's Law is associated with which type of summation?

• A. Spatial summation
• B. Temporal summation
• C. Dynamic summation
• D. Static summation

Answer: (B)

Bloch's Law pertains to temporal summation, which refers to the phenomenon where the perception of stimuli increases over time when multiple stimuli are presented in quick succession. This law describes how the frequency of a stimulus can impact its perceived intensity, particularly in relation to vision and visual perception. In temporal summation, when stimuli are presented rapidly one after another, the visual system integrates these inputs over a brief period, allowing for a cumulative effect where the visual response is greater than the response to a single stimulus presented separately. This is especially relevant for detecting low-intensity stimuli that may not be perceived effectively as isolated presentations. Understanding Bloch's Law helps in grasping how our visual system interprets sequences of events and changes in light over time, underlining the importance of timing in visual perception.
