Abstract

The impact of age of acquisition (AoA) on object recognition was explored in three experiments measuring visual duration threshold (VDT) for the identification of pictures labelled with early and late acquired names. Participants viewed briefly displayed images preceded and followed by a pattern mask. The minimum display duration required for correct identification was shorter for pictures labelled with early names than for those labelled with late names. In Experiments 2 and 3 we explored the effects of two forms of visual degradation on VDT for pictures with early and late acquired names. Both degradation by superimposed visual elements, and degradation by contrast reduction extended VDT, but only the former interacted with AoA. We conclude that both AoA and degradation by superimposed visual elements affect the efficiency of visual object recognition, but only degradation by contrast and not AoA affects the efficiency of earlier pre-recognition processes.
