Abstract
A means of presenting information temporally has been developed from the basic research on reading. Temporal displays allowed for faster processing speeds by reducing the number of saccades normally required to process spatially distributed information; however, a potential disadvantage to using temporal displays was an increased rate of error. Payne and Lang reported that a tradeoff between speed and accuracy is sometimes the result of using temporally distributed displays. As they used an alphabetic coding scheme which may not have facilitated the most optimal stimulus-response mapping, the current experiment tested the effects of a directional coding scheme on a temporally distributed display with 24 subjects. Analysis indicated the coding scheme did improve processing speed on the temporal display, but the error rate for the temporal display was higher than with the alphabetic coding scheme. Therefore, the limitation of temporal displays in a tradeoff between speed and accuracy persisted using the directional coding scheme.
