The difference threshold is sometimes called the just noticeable difference (jnd), and it depends on the strength of the stimulus.
What is the smallest detectable difference between two stimuli?Just noticeable difference (JND): The smallest detectable difference between two stimuli, or the minimum change in a stimulus that can be correctly judged as different from a reference stimulus; also known as difference threshold.
What is the point at which a person can detect a stimuli 50% of the time?An absolute threshold is the smallest amount of stimulation needed for a person to detect that stimulus 50% of the time.
Is the lowest level of stimulation that a person can consciously detect 50 percent of the time the stimulation is present?Absolute Threshold
the lowest level of stimulation that a person can consciously detect 50 percent of the time the stimulation is present.
