Question: 1 / 400

True or False: Absolute threshold means everyone can detect a certain stimulus 50% of the time.

True

False

The concept of absolute threshold refers to the minimum intensity of a stimulus that can be detected by a sensory system 50% of the time under ideal conditions. This threshold is not universally applicable to every individual or under all circumstances, as personal differences in sensory perception and environmental factors can affect detection. For example, one person might be able to notice a faint sound at a certain frequency, while another may not. This variability means that while the absolute threshold is a useful guideline, it does not imply that every individual will consistently detect a stimulus 50% of the time. Thus, the statement is false because it oversimplifies the concept and doesn't account for individual differences in sensory perception.
