Abstract

Two eye movement experiments investigated intra-word spacing (the space between letters within words) and inter-word spacing (the space between words) to explore the influence these variables have on eye movement control during reading. Both variables are important factors in determining the optimal use of space in a line of text, and fonts differ widely in how they employ these spaces. Prior research suggests that the proximity of flanking letters influences the identification of a central letter via lateral inhibition or crowding. If so decrements in intra-word spacing may produce inhibition in word processing. Still other research suggests that increases in intra-word spacing can disrupt the integrity of word units. In English, inter-word spacing has a large influence on word segmentation and is important for saccade target selection. The results indicate interplay between intra and inter word spacing which influence a font’s readability. Additionally, these studies highlight the importance of word segmentation processes and have implications for the nature of lexical processing (serial vs. parallel).
