A)The point at which two stimuli are recognized as different 25% of the time.
B)The point at which two stimuli are recognized as different half of the time.
C)The point at which two stimuli are recognized as different all of the time.
D)Sthe mallest quantity of physical energy that can be detected.

Question

Quizplus · Accepted Answer

The operational definition of a difference threshold (also known as a just noticeable difference) is the smallest difference in intensity between two stimuli that can be detected 50% of the time. This means that at this threshold, the stimuli are recognized as different half of the time. Option A is incorrect because recognizing two stimuli as different only 25% of the time would indicate that the difference threshold is much lower than it actually is. Option C is incorrect because if the stimuli are recognized as different all of the time, then the difference threshold would be higher than it actually is. Option D is incorrect because this definition pertains to the absolute threshold, not the difference threshold.
