“…The results of a large number of studies argue for a progressively relaxed cutoff in any discrimination model that postulates a stopping criterion based on S's expected accuracy. These experiments measured time and accuracy when the discrimination difficulty varied randomly from trial to trial (Henmon, 1906;Lemmon, 1927;Kellogg, 1931;Johnson, 1939;Festinger, 1943a, b;Birren & Botwinick, 1955;Botwinick, Brinley, & Robbin, 1948;Thurmond & Alluisi, 1963;Morgan & Alluisi, 1967;Pickett, 1964Pickett, , 1967. For trials on which the more difficult stimuli occurred: (1) mean RTs were slower and (2) error rates were higher.…”

“…In particular, Gregg (1954), Hodge (1959), Montague (1965), Egeth (1966), and Morgan and Alluisi (1967) reported substantial interference effects due to variation along dimensions of the stimulus display that were supposedly irrelevant, while Archer (1954), Morin et al (1961), Fitts and Biederman (1965), and Imai and Garner (1965) reported no such interference. This literature has been reviewed in some detail by Egeth (1967).…”

Multidimensional stimuli, which could vary on one, two, or all three dimensions within a particular series, were presented to Ss who were required to classify each stimulus on the basis of its value on a specified dimension. The prior relevance of the irrelevant dimensions and the difficulty of the task were varied. Latency and error data indicated that Ss were unable to gate the irrelevant information effectively. It was further concluded that this lack of perfect gating cannot be simply attributed to competing responses learned during the experiment.

“…This explanation is made more plausible by evidence in the literature that Ss cannot "filter out" color when it is an irrelevant dimension (Egeth & Pachella, 1969;Morgan & Alluisi, 1967).…”

Three experiments are described, in which Ss had to decide whether or not single stimuli, varying along the dimensions of shape and color, satisfied a given criterion. In different conditions, the number of dimensions relevant to the criterion was varied. The first experiment indicates that simple interpretations of a standard Nickerson procedure are potentially artifactual. In the last two experiments, a design involving different difficulties of discrimination was used so that a serial interpretation of the results could be convincingly rejected, even for unpracticed Ss, These results strongly support the view that perceptually parallel processing normally occurs in the identification of single multidimensional stimuli. By this interpretation, apparently similar tasks may produce different patterns of results because of the use of different decision processes by the Ss.
