In relation to light adaptation, which law would not apply?

• A. Dowling-Rushton Law
• B. Weber's Law
• C. Hering's Law
• D. Rico's Law

Answer: (A)

The justification for identifying the Dowling-Rushton Law as the answer lies in its specificity to dark adaptation rather than light adaptation. The Dowling-Rushton Law describes the relationship between the intensity of light and the time required for an observer's visual system to adapt to dark conditions. Since the question focuses on light adaptation, this law does not apply. In contrast, Weber's Law pertains to the perception of changes in stimulus intensity and how the perceived change is proportional to the original stimulus intensity, which is relevant in both light and dark adaptations. Hering's Law relates to the opponent-process theory, explaining how different types of photoreceptors interact during adaptation to light and color perception. Rico's Law, although less commonly referenced, pertains to the efficiency of visual processing relating to stimulus intensity changes. This context emphasizes that the Dowling-Rushton Law's application to dark adaptation distinguishes it from the other laws, which are applicable in the realm of light adaptation and visual processing.
