Question

Quizplus · Accepted Answer

Weber's law is a principle in psychology that relates to the perception of changes in a given stimulus. It states that the just noticeable difference (jnd) for a stimulus is proportional to the magnitude of the original stimulus. This means that the amount of change required for a person to notice that something has changed is relative to the initial intensity of the stimulus. Weber's law does not directly apply to recall and recognition performance, reaction time and accuracy performance, or the relationship between IQ scores and academic performance.
