PSYCHOPHYSICAL METHODOLOGY IV: PHI GAMMA HYPOTHESIS AND THE METHOD of limits,

Abstract

Assuming the phi-gamma hypothesis, deductions concerning the Method of Limits (ML) are derived on the basis of a probability model. For a given step size, the selection of the initial stimulus for the ascending series, or for the descending series, has little effect on the summary statistical measures of the ML. Estimates of ML statistics are derived for different step sizes, and these estimates are used to estimate the mean and standard deviation of the phi-gamma hypothesis. Also considered are how summary statistical measures of the ML are influenced by extremely large and small step sizes, and by the definition of a ML threshold. (Author)
