Match the following:
| List I | List II |
|---|---|
| A. Weber's Law | I. Sensation grows as a logarithmic function of stimulus intensity |
| B. Fechner's Law | II. JND is proportional to the original stimulus |
| C. Absolute threshold | III. Minimum intensity needed to detect a stimulus |
| D. Just Noticeable Difference (JND) | IV. Smallest detectable difference between two stimuli |
Pick an option to check yourself, or open the answer below.
Show answer & explanation
Correct answer: C. A-II, B-I, C-III, D-IV
Explanation
Weber: the JND is proportional to the standard; Fechner: sensation grows with the log of intensity; absolute threshold is the minimum detectable intensity; JND is the smallest detectable difference.
