Discrimination Judgments of Frequency-Modulated Tones
Three subjects were repeatedly presented with all possible pairs of nine frequency-modulated (FM) tones. The tones had one out of nine different modulation rates, a random modulation phase, a duration of 500 ms, a sound pressure level of 60 dB, and a center frequency of 1000 Hz.
On each trial, subjects judged whether the two FM tones sounded same or different.
A data frame of eight variables and 26,820 observations:
the response of a subject in each trial, either
sfor same or
reaction time from stimulus onset until reaction of subject.
number of experimental session.
stimulus (FM rate in Hz) which was presented in the first observation area; in this case: first.
stimulus (FM rate in Hz) which was presented in the second observation area.
random modulation phase shift for stimulus presented in the first observation area.
random modulation phase shift for stimulus presented in the second observation area.
