A tone-deaf person would probably not be able to tell two musical notes apart unless they were very different. We could say that this person has a relatively large: A. just noticeable difference. B. relative threshold. C. absolute threshold. D. detection threshold.

Short Answer

Expert verified
Answer: Just noticeable difference (JND).

Step by step solution

01

Defining the Terms

Before selecting the appropriate term, it's essential to define each one and understand its relationship to sensory perception. A. Just Noticeable Difference (JND): The smallest difference between two sensory stimuli that the observer can detect 50% of the time. It's also known as the difference threshold. B. Relative Threshold: The difference threshold or JND, expressed as a percentage or proportion of the stimulus. This term is not frequently used in sensory perception literature. C. Absolute Threshold: The smallest intensity of a stimulus that can be detected 50% of the time by an observer. This represents the minimum amount of sensory input required to perceive the stimulus. D. Detection Threshold: This term is similar to the absolute threshold; it refers to the minimum intensity level required to reliably perceive a stimulus.

Analyzing the Context of the Problem

In this problem, a tone-deaf person cannot distinguish between two musical notes unless they are significantly different. They require a large difference between the notes before they can correctly identify them as different sounds.
03

Selecting the Appropriate Term

Considering the definitions of each term and the context of the problem, the most suitable term to describe the tone-deaf person's inability is A. just noticeable difference (JND). This term represents the minimum difference in stimuli that the individual can perceive, and in this case, it would be a large difference due to their tone-deafness.
