Kornbrot (1978) compared Luce's (1963)choice model and the (constant-variance) Thurstone categorical judg- ment model (Thurstone, 1927; Torgerson, 1958)on their ability to account for unidimensional absolute identifica- tion performance. Two subjects were required to iden- tify eight auditory stimuli varying in loudness in a neu- tral and a payoff-biased condition. Kornbrot concluded that the experimental results provided strong evidence against the choice model of category judgment, and that the Thurstone model yielded impressive fits to the iden- tification data. In this note, I suggest that Kornbrot's con- clusion regarding the choice model was too strong. Korn- brot fitted a special case of Luce's choice model to the identification data by constraining the similarity parameters in the general model. The special-case choice model may have provided poor fits because inappropri- ate constraints were assumed. A choice model with slightly modified similarity constraints yields impressive fits to the identification data, ones that compare favora- bly with the fits of the Thurstone model. Assume n stimuli in an absolute identification experi- ment. Accordingto Luce's (1963)choicemodel, the prob- ability that a subject makes response j given stimulus i, P(Rj ISi), is given by
