Summary
Western language word recognition shows a rightward bias. This reading habit bias can be altered by presentation strategies, suggesting it
Area of Science:
- Cognitive psychology
- Visual perception
- Reading science
Background:
- Western languages exhibit a rightward bias in word recognition, meaning words presented to the right of visual fixation are more accurately identified.
- This rightward bias is a well-documented phenomenon in reading behavior.
Purpose of the Study:
- To investigate if the rightward bias in word recognition extends to visual field eccentricities above and below the fixation point.
- To determine if different stimulus presentation strategies can alter this established rightward bias.
Main Methods:
- Participants performed word recognition tasks with stimuli presented at various eccentricities (up to 8 degrees) above, below, and to the right of fixation.
- Stimuli were presented along a horizontal meridian and within a random mosaic of possible locations to test different presentation strategies.
Main Results:
- A significant rightward bias was confirmed, extending up to approximately 0.9 degrees to the right of fixation along the horizontal meridian.
- The rightward bias was significantly reduced when words were presented within a randomized mosaic of all possible locations, indicating the bias is malleable.
Conclusions:
- The observed left-right asymmetry in word recognition is likely a consequence of learned reading habits and attentional focus within specific visual space areas.
- This finding challenges the notion of an innate visual field superiority for word recognition, emphasizing the role of experimental paradigms and reading strategies.
