There are two empty duration time spans which are divided by short bursts. And one is exactly twice as long as the other, However there are some ocations when we felt it not so long as it is.
How does this time lag between objective time span and subjective one happen? About this we made an extriment of magnitude estimation for relative judgement which is often regarded as one of traditional method of psychophysic. We examined the next two formuras.
τ (t) =k (t+α) (1)
log τ (t) =e log t + k (2)
