Abstract
A “fine grain” magnitude scale for duration is derived. It consists of two parts, each of which confirms the power law ψ=aϕb. For intervals shorter than 500 msec the characteristic exponent b is approximately equal to 0.6, for longer intervals b≈1.1. The latter result is in accord with earlier studies. The relation of this transition to similar effects obtained in indirect scaling experiments is discussed. The present results rule out the possibility that these effects are artificial byproducts of the motor response elicited by the indirect methods.
