Perceived numerosity a comparison of magnitude production magnitude estimation and discrimination judgments



Perceived numerosity a comparison of magnitude production magnitude estimation and discrimination judgments



Perception & Psychophysics 35(6): 536-542



Modalities with a higher Weber fraction have tended to have a lower power-function exponent. Within a modality the Weber fraction and power-function exponent for individual subjects were unrelated, and this finding for the numerosity dimension was confirmed. More important than discriminability in the judgment of numerosity were cognitive factors. A single feedback trial considerably reduced intersubject variability on the magnitude-estimation exponent, although it failed to eliminate individual differences completely (precue and postcue exponents correlated significantly, r = + 0.50). Intrasubject variability, by contrast, seemingly did not involve the underlying exponent. Numerosity generally was underestimated and the power-function exponent was 1.08 for magnitude production and 0.80 for precue magnitude estimation. Males and females did not differ in exponent, perhaps because the present procedure allowed self-selection of individuals more interested in numerosity tasks.
