Psychophysical study of numbers

II. Theoretical models of number generation
  • Elliot Noma
  • John C. Baird


This paper develops three theoretical models to predict the numbers generated by Ss in an experiment described by Baird and Noma, 1975, Exp. II. The models (digit, base, and quarter) are each grounded on different assumptions about the process underlying number generation without the constraints of physical stimuli usually present in psychophysical tasks. Each of the models proved applicable to a restricted subrange of the physical continuum from 1–1000. A combination of models seems necessary to adequately predict number generation.
