Explanation:

Difference threshold: In psychology, the term difference threshold was proposed by Ernst Heinrich Weber, while experimenting on perceptional threshold of lifted weights. The difference threshold is also referred to as just noticeable difference or JND. It is defined as the minimal difference in the stimulation process that an individual can detect fifty percent of the time and the person experiences the difference threshold as JND.

In the question above, Annalisa experiences an exceeded difference threshold.
