When you press gently on the side of your eyeball and experience the visual sensation of colored light,you illustrate
A) the law of specific nerve energies.
B) Weber's Law.
C) the Young-Helmholtz Law.
D) the law of sensory pressure.

Question

Quizplus · Accepted Answer

The law of specific nerve energies explains that different sensory modalities are encoded by different nerve fibers. In this case, pressing on the side of the eyeball activates the nerve fibers in the retina, which are responsible for encoding visual information. The experience of colored light is therefore consistent with the activation of these visual nerve fibers, supporting the law of specific nerve energies. Weber's Law and the law of sensory pressure are not relevant to this phenomenon, and the Young-Helmholtz Law explains how color vision is created from the stimulation of three types of cones in the retina, but it does not apply to this specific example.
