• Stevens and Rubin (1970) investigated the size-weight illusion using magnitude estimation method and Anderson (1970) investigated the same illusion by rating method. But, in general, both methods of magnitude estimation and rating were criticized as biased (cf, Anderson, 1981; Parducci, 1983). In this paper, size-numerosity illusion was investigated using simultaneous pair comparison method, which did not force the subject to make magnitude estimation or rating of the quantity, and applying the scalar product model to the data. The nonmetric solution of the analysis was very successful and indicated that the size-numerosity illusion can be described by the same information integration process as in the case of the size-weight illusion, i.e. the averaging model, and Scalar Product Model can clearly display individual differences of the illusion.
