Manuel is participating in a sensory experiment where he is told to listen to pairs of tones of different frequencies and indicate if the tones are the same or different in terms of the perceived pitch.
The researcher is interested in determining the minimum frequency change needed for Manuel to recognize the tones as being different on half of the trials. It appears as though the researcher is trying to measure Manuel's
a. absolute threshold.
b. just noticeable difference.
c. evoked potentials.
d. performance speed.

b. introspection.
c. blind procedures.
d. confirmatory bias.
