ABSTRACT
Stimulus identification data have attracted considerable attention from many researchers (e.g., Ashby & Perrin, 1988; Keren & Baggen, 1981; Nosofsky, 1985b; J. E. K. Smith, 1980, 1982; Takane & Shibayama, 1986; Townsend & Ashby, 1982; Townsend & Landon, 1982). In a stimulus identification experiment one of n stimuli is randomly selected and presented on each trial, and the subject’s task is to identify the stimulus. The basic data thus consists of a set f j/i (i = 1, …, n; j = 1, …, n) of frequencies of response j when stimulus i is presented, with f i = Σi f j/i the total number of presentations of stimulus i.
