A Pilot Study: Designing and Testing the Task Parameters

Abstract

The aim of this pilot study was to test the validity, efficiency and measurements of a two-digit number comparison study. Number perception, its neural basis and its relationship to how numerical stimuli are presented have been challenging research topics in cognitive neuroscience for many years. A primary question that has been addressed is whether the perception of the quantity of a visually presented number stimulus is dissociable from its early visual perception. The present study examined the possible influence of visual quality judgment on quantity judgments of numbers. To address this issue, a two-digit number comparison task was developed. We suggest that the design parameters affect the accuracy of the results.
