Abstract
In an attempt to measure how mode of response might affect psychophysical judgment, 18 subjects were asked to give magnitude estimates of the loudness of 1000-Hz tones at various sound pressure levels in each of two sessions. In one session, the subjects responded by giving their numerical judgments orally to the experimenter; in the other session, they did so by entering their judgments manually on a computer-controlled keyboard. Mode of response had no effect on the loudness function’s log-log slope and a small, statistically unreliable, effect on the function’s intercept.
