Question

Quizplus · Accepted Answer

Spatial summation is the process by which multiple weak stimuli are combined to generate a larger signal. Choice A involves the presentation of two or more weak stimuli at the same time, which would lead to spatial summation. Choices B and C involve other processes, and choice D refers to temporal summation rather than spatial.
