What does a lower threshold indicate about sensitivity?

A lower threshold indicates higher sensitivity because it means that a stimulus can be detected with less intensity or lower levels of stimulation. In sensory perception, the threshold refers to the point at which a stimulus is strong enough to be perceived. When this threshold is low, it indicates that the sensory system is highly responsive and can detect even weak stimuli. This is particularly relevant in fields such as vision and hearing, where a lower threshold can enhance an individual's ability to perceive subtle changes or faint signals in their environment. As a result, a lower threshold directly correlates with increased sensitivity of the sensory system.
