Assume that an experiment has determined that, for monkeys, the Weber fraction for vision is 1/25 while that for audition is 1/5. What does this tell us?

A) The monkey can make finer visual discriminations than auditory discriminations.
B) The monkey can make finer auditory discriminations than visual discriminations.
C) Over the range of perceptible stimuli, the monkey's visual sense is as keen as its auditory sense.
D) An auditory stimulus is perceived as being five times as intense as a visual stimulus.

Final Answer : A, Explanation :  The Weber fraction (difference threshold ratio) indicates the smallest relative change in a stimulus that can be perceived. A smaller Weber fraction, like 1/25 for vision, means finer discrimination ability compared to a larger fraction, like 1/5 for audition, indicating less fine discrimination ability.
