Phonological coding during reading

Area of Science:

• Cognitive Psychology
• Neuroscience
• Linguistics

Background:

• Phonological coding, the recoding of written information into a sound-based code, is central to understanding silent reading.
• Despite extensive research, debate persists regarding the precise timing and functional role of phonological coding during reading.

Purpose of the Study:

• To synthesize existing research on the time course and function of phonological coding in silent reading.
• To critically evaluate various theories on phonological coding's role in lexical access, comprehension, and memory.
• To examine the implications of phonological coding research for prominent models of word identification.

Main Methods:

• Review of empirical studies employing response time measures, eye-tracking, EEG/MEG, and concurrent articulation tasks.
• Analysis of research on phonological coding in prelingually deaf readers to address epiphenomenal theories.
• Synthesis of findings in relation to established models of word identification.

Main Results:

• Evidence suggests phonological codes are involved in both early (prelexical) and late (postlexical) stages of reading.
• The function of phonological coding appears multifaceted, aiding lexical access, comprehension, and short-term memory.
• Research on deaf readers provides crucial insights into the necessity of phonological codes.

Conclusions:

• Phonological coding is a significant component of skilled silent reading, not merely an epiphenomenon.
• Understanding its temporal dynamics and functional contributions is essential for refining models of reading and word recognition.
• Future research should continue to explore the interplay between phonological coding and other reading processes.
