Answer:
just-noticeable difference
Explanation:
Based on the information provide can be said that in this scenario Brenda's detection of this slight increase in volume demonstrates the just-noticeable difference or JND. In the context of psychophysics, this term refers to the amount in which something needs to be changed in order for the individual in question to be able to notice or detect the difference, at least 50% of the time in which they are exposed to it. Which is the what is being demonstrated by Brenda in this scenario.
Answer:
Just noticeable difference
Explanation:
The just noticeable difference is the difference in threshold, that is the minimum level of stimulation that a person can detect 50 percent of the time
The absolute threshold for sound, for example, would be the lowest volume level that a person could detect. The just noticeable difference would be the smallest change in volume that a person could sense. Brenda increasing the volume only 5 decibels is the just noticeable difference that Brenda is able to detect
