Spelling-sound regularity effects on eye fixations in reading.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Reading Science

Background:

• The frequency x regularity interaction is a known phenomenon in word recognition tasks.
• Previous eye-movement studies on this interaction during reading have yielded inconsistent results.
• The role of parafoveal information in modulating this interaction remains underexplored.

Purpose of the Study:

• To investigate the frequency x regularity interaction in reading.
• To examine the influence of parafoveal preview on this interaction.
• To determine the timing of phonological code activation during reading.

Main Methods:

• Participants performed a reading task with controlled parafoveal previews.
• Eye movements were monitored to record fixation durations and landing positions.
• Stimuli differed from those used in prior eye-movement research on this topic.

Main Results:

• The frequency x regularity interaction was observed when parafoveal preview was valid.
• This interaction disappeared when the parafoveal preview was invalid.
• Fixation patterns indicated a modulation of processing based on preview validity.

Conclusions:

• Parafoveal information plays a critical role in the emergence of the frequency x regularity interaction during reading.
• The findings support the hypothesis that phonological code activation is an early process in reading.
• This study provides new insights into the interplay of visual and lexical factors in skilled reading.
