Scatterplots of the relationship between sustained attention and the tau of naming latencies.

<p>Tau of naming latencies presented separately for monosyllabic and disyllabic words separately in the single object task (monosyllabic panel A, disyllabic panel B) and the double object task (monosyllabic panel C, disyllabic panel D). Sustained attention is indexed by the mean RT on the digit discrimination task (DDT).
