FIG 1. Reaction times when subjects identified stimuli (control task) and ordered letters, numbers, and shapes. A distance effect (
, P < .05) was seen with numbers and shapes, as subjects were faster ordering far numbers (OFN) compared with near numbers (ONN), and far shapes (OFS) compared with near shapes (ONS). No statistically significance difference was seen between near letters (ONL) and far letters (OFL). IFL indicates identify far letters; INL, identify near letters; IFN, identify far numbers; INN, identify near numbers; IFS, identify far shapes; INS, identify near shapes.
