Tone Matching Task

The tone matching task is designed to measure pitch perception. Subjects are presented with pairs of 100 ms tones with 500 ms inter-tone intervals and are asked to indicate whether they sounded the same or different. In order to minimize learning effects, 3 different base tones are used: 500, 1000, or 2000 Hz. Half the stimuli pairs are identical and half include a manipulated tones, which differed in frequency by 1%, 2.5%, 5%, 10%, 20%, or 50% of their counterpart.
