Eye-voice and finger-voice spans in adults’ oral reading of connected texts
Implications for reading research and assessment
The present paper investigates the interaction between eye movements, voice articulation and the movements of the
index finger dynamically pointing to a text line in oral finger-point reading of Italian. During finger-point
reading, the finger appears to be ahead of the voice most of the times, by a margin that is significantly modulated by the
distribution of phrasal and prosodic units in the reading text. Eye movements replicate the same effects on a different time
scale. The eye is ahead of both voice and finger by a wide margin (confirming evidence observed for English and German sentence
reading), while showing a tendency to re-synchronise with voice articulation at the right edge of strong prosodic units (sentence
boundaries). Our evidence suggests a multicomponent view of the time span between the eye/finger and the voice. The span is shown
to be the dynamic outcome of an optimally adaptive reading strategy, resulting from the interaction between
individual decoding skills, the reader’s phonological buffer capacity, and the structural complexity of a reading text. Proficient
readers modulate their span to compensate for the different timing between word fixation and word articulation, read faster, and
dynamically adjust their processing window to the meaningful, prosodic units of a text.
