Age of acquisition and word frequency in written picture naming

This study investigates age of acquisition (AoA) and word frequency effects in both spoken and written picture naming. In the first two experiments, r eliable AoA effects on object naming speed, with objective word frequency c ontrolled for, were found in both spoken (Experiment 1) and written picture naming (Experiment 2). In contrast, no reliable objective word frequency e ffects were observed on naming speed, with AoA controlled for, in either sp oken (Experiment 3) or written (Experiment 4) picture naming. The implicati ons of the findings for written picture naming are briefly discussed.
