Beyond the bridge: an integrative developmental framework for first-language reading fluency

Reading fluency is central to reading development, yet its conceptual boundaries and changing relations with word recognition and comprehension remain unsettled. This conceptual analysis proposes that fluency development changes how processing time is organized across connected text. As word identification consolidates, timing is hypothesized to become increasingly responsive to linguistic integration demands and reading goals. Fluent performance can therefore include selective local slowing followed by recovery of continuity. The framework draws on established accounts of automaticity, synchronization, word-to-text integration, and strategic regulation. Fluency is characterized through accuracy, temporal continuity and pace regulation, and, in oral reading, prosodic organization. Connected-text coordination is proposed to explain the temporal relationships among word identification, linguistic grouping, and local meaning updating. Three overlapping configurations organize the relative prominence of lexical constraints, integration demands, and regulation by meaning and reading goals. Their number and developmental ordering remain hypotheses. Reading experience can support lexical consolidation and better calibrated linguistic expectations, with oral-language resources, morphological development, compensatory profiles, and orthographic variation constraining the account. The primary hypothesis predicts that, as word identification consolidates under comparable reading conditions, the association between global reading rate and comprehension will weaken, while the association between demand-sensitive local timing and comprehension will remain stable or strengthen. This joint prediction follows from the proposed change in processing constraints, beyond faster word identification alone. Secondary hypotheses address goal-dependent rereading and generalization across oral and silent reading. Evaluation requires independently specified demands and outcomes, longitudinal measurement, and comparison with existing accounts. The framework's proposed contribution is a developmental explanation linking the organization of processing time to the changing informativeness of fluency indicators. Its explanatory value depends on these commitments distinguishing it from alternative accounts.
