Erin participates in an experiment in which she is asked to taste 10 different solutions and rate how sour each one is on a scale from 0 to 10. This is an example of:
A) the method of limits for measuring discrimination
B) the method of adjustment for measuring discrimination
C) the cross-modality matching procedure
D) the magnitude estimation technique

Question

Quizplus · Accepted Answer

The magnitude estimation technique is used to measure the perceived intensity of a stimulus, in this case sourness, by asking participants to rate it using a numerical scale. The method of limits and the method of adjustment are both used to measure discrimination thresholds, while the cross-modality matching procedure is used to match intensities across different sensory modalities (e.g. matching the brightness of a light to the loudness of a sound).
