Hypothesis
Do fast readers rely most on letter-by-letter decoding, whole word shape, or sentence context?
Conclusion
The study found that each reading process contributes equally to reading rate, regardless of whether the other processes are operating.
Supporting Evidence
- Each reading process contributes equally to reading rate.
- The main effects of letter-by-letter decoding, whole word shape, and sentence context were significant.
- Fast readers utilize context more effectively, but letter decoding remains the primary contributor to reading speed.
Takeaway
When we read, we use three different ways to recognize words: by letters, by the shape of the whole word, and by the context of the sentence. Each way helps us read just as fast as the others.
Methodology
The study manipulated text to selectively knock out each source of information while measuring reading rates across different conditions.
Limitations
The study's findings may not generalize to all reading contexts or populations.
Participant Demographics
Eleven observers aged 17–25 with normal or corrected-to-normal vision and fluent in English.
