q2 · i? · causal · r1

The author summarizes about fifteen years of data collection in the Iowa laboratory on features involved in pitch discrimination, presented as the first clear-cut demonstration of the distinction between psycho-physic sensibility and the apperceptive use of a sense. No statistics are printed in this summary.

"it has been abundantly proved that the test of pitch discrimination may be so elemental that there can be no improvement with practice and there will appear no significant variation with age, say from the age of eight to forty."
