The bisection method of animal psychophysical scaling was examined as a measurement procedure. The critical assumptions of bisection scaling, as described by Pfanzagl (1968), were tested to determine if a valid equal-interval scale could be derived. A valid scale was derived in which subjective time for the rat was a power function of real time. Bisection points were found to be context dependent, because the spacing of stimuli significantly affected the bisection points. Such context effects… CONTINUE READING
