Summary
Thai children exhibit adult-like eye movement patterns when reading, utilizing word and character frequency to guide their gaze. Spacing aids reading efficiency and reduces viewing time in young readers.
Area of Science:
- Cognitive Psychology
- Developmental Psychology
- Linguistics
Background:
- Adult Thai readers, despite reading a scriptio continua language without spaces, show oculomotor patterns similar to readers of spaced languages.
- These patterns suggest that word boundaries are perceived and utilized even without explicit spacing cues.
Purpose of the Study:
- To investigate whether Thai children display similar oculomotor reading patterns as adults.
- To examine the influence of first and last character frequency and word frequency on children's eye movements in both spaced and unspaced Thai text.
Main Methods:
- 18 Thai children silently read normal unspaced and spaced Thai text.
- Linear mixed-effects models analyzed viewing time (first fixation duration, single fixation duration, gaze duration) and landing site location.
- The study assessed the impact of first character frequency, last character frequency, and word frequency on reading patterns.
Main Results:
- Thai children's eye movement patterns closely resembled those of adult Thai readers.
- First character frequency and word frequency significantly influenced children's landing sites, directing gaze towards the word center.
- Text spacing improved the utilization of first character frequency and reduced overall viewing time.
Conclusions:
- Thai children employ similar oculomotor control mechanisms for reading as adults, regardless of text spacing.
- Eye movement patterns in reading appear to converge on optimal landing sites using available visual cues.
- The influence of last character frequency on reading metrics like single fixation duration and gaze duration emerges as a later developmental skill.
