Individuals received either a regular print or braille version of the test, depending on their needs.

A total of 47 adults participated in the study; 24 (51%) were print readers, 23 (49%) were braille readers. The print readers had normal vision, and the braille readers were either totally blind or had limited useful vision and read braille.

Oral reading rate, silent reading rate, and the number of minutes studying and the number of words studied per minute were used as dependent variables.

Average print-reading rate ranged from 30% to 60% faster than the average Braille reading rate. Less than one third of the Braille readers read slower than the print readers. Based on their performances in the different modes (e.g., oral, silent, studying), it appears that Braille and print readers employ similar strategies for different tasks.
