| This graph shows the
results of the experiment. The dashed lines show the thresholds when just
one of the tone (1st or 2nd) is presented; the solid curve shows thresholds
when the tones are presented in sequence. On the x-axis is the level of the
noise between the tones in the three conditions. Thresholds were better when
there were two tones instead of one, and the level of the noise doesnŐt make
much difference. This result supports the multiple looks theory and argues
against the multiple integrators theory, |
