Training reduced crowding in peripheral vision, improving letter identification by 88%. However, this did not significantly enhance peripheral reading speed, suggesting crowding reduction alone is insufficient for faster reading.

Area of Science:

  • Vision Science
  • Perceptual Learning

Background:

  • Crowding, the inability to identify letters amidst distractors, is linked to slow peripheral reading.
  • Understanding crowding's impact on reading is crucial for visual processing research.

Purpose of the Study:

  • To investigate if training can reduce crowding in peripheral vision.
  • To determine if reduced crowding improves peripheral reading speed.

Main Methods:

  • Assessed crowding extent and reading speed at 10 degrees inferior visual field before and after training.
  • Measured performance across various print sizes and letter separations.

Main Results:

  • Letter identification improved by 88% at trained separations, with a 38% decrease in crowding extent.

  • Peripheral reading speed showed a minimal 7.2% improvement.

    • Conclusions:

    • Training effectively reduces crowding in peripheral vision.
    • Crowding reduction alone does not substantially improve peripheral reading speed.
