Adelman, J. S., & Stewart, N. (2006). Absolute identification is surprisingly faster with more closely spaced stimuli. In R. Sun & N. Miyake (Eds.), Proceedings of the twenty-eighth annual conference of the Cognitive Science Society.

Bow and set size effects on response times in absolute identification mirror the effects on accuracy: Central stimuli and stimuli in large sets are responded to more slowly and less accurately. In an analysis of the response time data from Experiment 1 of N. Stewart, G. D. A. Brown and N. Chater (2005), involving the absolute identification of tone frequency (pitch), we find that in contrast to the accuracy data, where widely spaced stimuli are responded to slightly more accurately than narrowly spaced stimuli, widely spaced stimuli receive slower responses than narrowly spaced stimuli. This result poses an additional challenge for models of absolute identification, as accuracy and response times are not jointly linked to some unified difficulty factor.
