摘要
ABSTRACTVarious manipulations have been shown to induce trade-offs in spatial and temporal acuity. Two experiments examine the role of the breadth of the attentional focus in such trade-offs. In the first experiment, exogenous attentional cues indicated 1, 2, 3, or 4 possible (contiguous) target locations. Half of the subjects performed a perceptual task on the target requiring spatial acuity – detecting spatial gaps in a ring; the other half of the subjects performed a task requiring temporal acuity – detecting a temporal gap in the presentation of the target ring. The results revealed a trade-off in spatial and temporal acuity: as the cue size increased, performance on the spatial task declined and performance on the temporal task improved. A second experiment replicated this pattern using two different tasks: a temporal order judgment task that assessed temporal acuity, and a task requiring the localization of a thin line that assessed spatial acuity.
