The statement that says "Absolute thresholds are the smallest amount of energy needed for conscious detection of a stimulus at least half the time it is present" is true.
The absolute threshold refers to the least amount of a stimulus required to report its presence on average, that is, it is the barrier that separates the stimuli that are detected from those that are not.
For a stimulus to be able to stimulate a receptor, its intensity must be greater than the so-called absolute threshold or sensory threshold, that is, the minimum intensity of a stimulus that an individual can detect.
The absolute threshold measured from the same stimulus varies according to the conditions of the experience, people, the parts of the body in which it is applied, and the duration of its application..
Therefore, we can conclude that the absolute threshold refers to the minimum energy level above which an individual can experience a sensation at least half the time it is present.
