Vuorinen, R. Anchor effects in category judgment of weight. Scand. J. Psychol., 1973, 14, 261–272.‐3 models of psychophysical judgment are tested in 4 experiments. The anchor effects obtained in these experiments deviate from their usually observed contrast properties violating both the “adaptation‐level” (AL) model and the “similarity classification” model. Results on comparative judgment disprove the assumed constancy of the parameters of the AL‐model. A comparison with the “response frequency equalization” model discloses that the AL‐model confounds genuine perceptual aspects of judgment with response determined factors (response bias) involved in category judgment. The present results are related to a critical evaluation of the general AL‐theory presented elsewhere (Vuorinen, 1973).
