Susan asked her roommate to lower the radio because she was trying to study. her roommate had turned the radio up originally from a volume level of 14 to 15, which was just enough for susan to detect the increase in volume. her roommate turned it back down to 14 after susan asked her to lower it. susan's detection of the increase and decrease of volume is an example of:

Susan's detection of the increase and decrease of volume is an example of: DIFFERENCE THRESHOLD ALSO KNOWN AS NOTICEABLE DIFFERENCE.

Explanation:

The just noticeable difference (JND), also known as the difference threshold is the change in stimulation that we are able to detect half of the time.

There is an absolute threshold which can be confused with difference threshold. Absolute threshold means we can detect smallest levels of stimulation like detecting the lowest volume of sound. Difference threshold means we can detect differences in level of stimulation like sensing the volume change in the radio.

For Susan to detect the difference between volume of 14 to 15 is a result of difference threshold.
