We present a framework for conceptualizing and analyzing responses to serial naming (rapid automatized naming) tasks, in which participants sequentially name stimuli presented simultaneously in an array. We aim to understand how these tasks are processed and why they are associated with reading skills. We analyzed responses by 298 Greek children in Grades 1, 3, and 5 to serial and discrete naming of digits, dice, objects, number words, and words. We measured the durations of silent and speech intervals in each task and grade and tested predictions about their relations based on a hypothesis of two overlapping processing stages. We found that articulation times were longer in the serial tasks, modulated by task demands. Total times were faster for serial than for discrete tasks, and their differences (serial advantage) were increasingly associated with the duration of speech intervals, consistent with efficient scheduling. Serial naming rate approached or exceeded the limits imposed by processing time, consistent with increasing processing overlap. These patterns were primarily observed for digits, number words, and—to some extent—dice, after Grade 1. Object naming seemed to pose different cognitive demands, stably across grades. Word reading exhibited the greatest differences between grades, consistent with rapid development of automaticity. We interpret the findings within a cascaded processing framework, in which performance is determined by the efficiency of cognitive scheduling of successive operations, constrained by susceptibility to interference from adjacent items. We propose that reading fluency is predicted by serial naming because it is also governed by the same scheduling constraints. Educational Impact and Implications Statement: Serial naming tasks, in which children are asked to name aloud an array of digits, pictures, or other familiar items, are widely used in educational assessment because they are associated with academic skills and, in particular, predict the development of reading fluency. In this study, we analyze children's vocal responses to serial naming tasks breaking them down into the duration of the spoken words and of any silent intervals between them. We interpret these durations under a theoretical approach that focuses on the scheduling and control of cognitive processes, that is, how the mind organizes and monitors its functions while going through the array naming the items. We claim that this approach can explain the established associations between naming and reading and can also shed light on the development of reading fluency and potential obstacles to that. Seeing fluency as not only about the automaticity of reading individual words, but also as a problem of cognitive scheduling, can inform our approaches to instruction and assessment by drawing attention to issues of interference and control and directing future research into potential interventions in those domains.
