  In this study we present a framework for conceptualizing and analyzing responses to serial naming (RAN) tasks, in which participants sequentially name a set of stimuli that are simultaneously presented in an array format. Our aim is to better understand how these tasks are processed and why they are associated with reading skills, particularly word reading fluency. 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 per item 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, further modulated by task demands. Total times were faster for serial than for discrete tasks, and the differences between the two (termed 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 (operationalized as discrete onset latency), 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 this pattern of 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 largely governed by the same scheduling constraints.

  Purpose: Previous studies examining the inter-relations between serial and discrete naming with reading have found that the ability to efficiently process multiple items presented in a sequence (indexed by serial naming) is a unique predictor of word- and text-reading fluency. However, conclusions have been tempered by the concurrent nature of the available data and the uniformly low demands of the materials (words and texts). Here we go beyond previous studies by using more varied materials to examine the relations of serial and discrete naming with the discrete reading of words and the serial reading of word lists and connected text over time. Method: Two hundred and eight English-speaking Canadian children (51% female, Mage = 7.2 years) were followed from Grade 2 to Grade 5 and were assessed on serial and discrete digit naming and serial and discrete word reading at both measurement points. Results: Strong associations between discrete naming and discrete reading already from Grade 2 indicated that short and high-frequency words were processed in parallel early in development. By Grade 5, when word recognition was presumably automatized, serial naming accounted for unique variance in serial reading of word lists and connected texts after controlling for discrete word reading. More importantly, Latent Change Score modelling indicated that serial naming was the main predictor of growth in serial reading from Grade 2 to Grade 5. Conclusion: These findings suggest that, beyond individual word recognition, reading fluency development also requires efficient processing of multiple items presented in serial format (termed “cascaded processing”).

  The serial advantage, defined as the gain in naming rate in the serial over the discrete task of the same content, was examined between grades and types of content in English and Greek. 720 English- and Greek-speaking children from Grades 1, 3, and 5 were tested in rapid naming and reading tasks of different content, including digits, objects, dice, number words, and words. Each type of content was presented in two presentation formats: multiple stimulus displays (i.e., serial naming) and isolated stimulus displays (i.e., discrete naming). Serial tasks yielded faster naming rates―irrespective of task content―in both languages. However, content-specific characteristics influenced the trajectory of the serial advantage between grades. Improvement in the serial advantage between grades was found to be greatest for word reading, which started off similar to object naming in Grade 1, but ended up similar to digit or dice naming by Grade 5. In addition, growth in serial advantage was found to be associated with growth in discrete naming rate only in grade level analysis. For individuals, greater serial advantage was found to rely on processing skills specific to serial naming rather than on differences in the rate of naming isolated items. Our findings suggest that group level findings may not generalize to individuals, and although practice and familiarity with the content on the naming/reading task may impact the development of serial advantage, isolated item identification processes contribute little to individual differences in the gain in serial naming rates.

  We recently pointed out that there is no evidence to support the commonly held view that there is something wrong with the brains of children who have great difficulty learning to read. In response, it was argued that dyslexia should be considered to be a neurodevelopmental disorder because of its potential to adversely affect quality of life, and because there are differences between the brains of people with different levels of reading skill. We agree with these two points, but they are irrelevant to the issue in question, because neither establishes the critical notion of disrupted neurodevelopment; that is, a brain fault. Differences between groups do not imply that any individuals are abnormal, and calling a brain improperly developed on the basis of cultural issues has absurd implications. Even calling brains atypical is unfounded because reference to typicality hinges on knowledge of the relevant distributions, which is currently lacking. Moreover, there is at present no obvious role for neurology- or neuroscience-based input for the critical issue of the assessment and remediation of the reading difficulties themselves. We reiterate our conclusion that there is, at the moment, no credible foundation to support the claim that dyslexia is a neurodevelopmental disorder.

• Protopapas, Athanassios (2023). Understanding fluency: Beyond the automaticity of single word reading. Vis sammendrag

  Fluent reading is the hallmark of the skilled reader and a foundation for efficient comprehension. Yet we understand surprisingly little about the nature and development of reading fluency. Current theoretical models seem to assume that fluent reading is a corollary of automatized individual word recognition; however, the efficiency of word list reading is more closely associated with serial digit naming (RAN; a nonreading task) than with the speed of reading individual words. In this talk I will present a framework for conceptualizing reading of word sequences as a serial naming task by focusing on parallel processing due to temporally overlapping processing of successive items. This approach helps us understand differences between naming tasks, their relationship to reading fluency, and -- most importantly -- what are the additional prerequisites to reading fluency, beyond automaticity, which end up dominating the development of word-level reading skill past the beginner stages. The enriched view of fluency enabled by this approach can shed light on why fluency interventions are less efficient than interventions targeting earlier stages of reading development, as well as on why certain types of interventions have emerged as consistently more effective.
