Abstract
Moyer & Landauer (1967) found that reaction time to indicate the larger of two digits was well described by an equation proposed by Welford (1960) as a general description of decision times for inequality judgments about perceived physical magnitudes. Moyer and Landauer suggested, therefore, that perceptual and symbolic inequality judgments might be based on similar processes. Parkman (1971) presented seemingly contrary evidence, but reanalyses of his data show that they are, in fact, fully consistent with our original account.
