Abstract
Observers are run on a partial-report task under three conditions of background luminance and with two target sizes. Small letters are presented in a small circular array, and large letters are presented in a large circular array. This manipulation is intended to keep letter legibility roughly equivalent as retinal eccentricity varies. At the photopic background level, there is no difference in the decay curves for the two target conditions; but at the mesopic and scotopic background levels, the large-size condition produces greater persistence. An explanation is offered in terms of differential contribution from the cone and rod systems.
