Cross-modality temporal resolution was measured using a procedure in which subjects adjusted the temporal asynchrony ΔT between a pair of stimuli to match that of a standard pair. The stimulus pairs were click-tap, click-flash, or tap-flash with values of ΔT betweel 0 and ± 120 ms. Also, judgments were obtained for within-modality stimulus pairs. The results indicate more precise temporal resolution (e.g., more reliable judgments) for click-tap pairs than for either click-flash or tap-flash pairs. Matches made using click-tap pairs are also more accurate (e.g., have smaller constant errors). Within-modality stimulus pairs are resolved more precisely than cross-modality pairs. However, the poorest within-modality resolution, found for flash-flash pairs, approaches that seen for click-tap pairs. These results are compared to the findings of Hirsh and Sherrick [J. Exp. Psychol. 61, 423-432 (1961)], who reported that the precision of order labeling is nearly invariant for various within-modality and cross-modality stimulus conditions. [ABSTRACT FROM AUTHOR] |
