Summary:

Procedure:

Experimenters examined errors and confusion matrices from different fonts. Stimuli were displayed at a vertical visual angle of 1 degree at 8 feet. Duration and luminosity were adjusted for each individual to achieve approximately 50% correct identification for each font.

Stimuli

The 26 uppercase letters, either in a dot-matrix font, or the stroked "Keepsake" font. Figure 1 from the article, reproduced below, shows the letters and font used.

Keepsake Font

Dots Font

Results

Confusion matrices for dot font and stroked font. Each row represents a stimulus, and each column a response.
