Frequency discrimination: effect of increment vs decrement

[Varghese Peter <vpeter@xxxxxxxxxxxxxxx>]

Hi everyone,

Is there any effect of direction of the comparison tone on frequency
discrimination thresholds? i.e., is the frequency discrimination
better (or worse)when the comparison tone is of higher frequency to the
reference tone comapred to the condition where the comparison tone is of
lower frequency? Is there any systematic effect that you are aware of?

Thanks,

Varghese
