Answer:
This question is incomplete. Here are the missing options:
- A) absolute threshold
- B) difference threshold
- C) human threshold
- D) sensory threshold
The answer is A) absolute threshold.
Explanation:
The absolute threshold is described as the minimal degree of a stimulus that can be detected by a person. This applies for all the senses. For example, the absolute threshold for hearing can be measured by a gradually increasing frequency of sound. A stimulus must be detected at least 50% to be considered as the absolute threshold. The lower the threshold, the more sensitive the person.
