(1969). The word-frequency effect and incongruity perception: Methodological artifacts? Perception and Psychophysics, 5(3), 161-162. doi:10.3758/BF03209549.
Two experimental results often reported in support of perceptual interpretations concerning the influence of set on perception are critically examined: (a) the relation between word frequency and recognition threshold, and (b) the
so-called compromise reactions between set and stimulus, Alter elimination of certain methodological artifacts (e.g.,
introduction of a temporal forced-choice method instead of the ascending-limits method), both phenomena disappear; the influence of set on perception appears to be wholly a matter of response bias.
