Syllables as Visual Units in Letter-String Perception.
Lesgold, Alan M.; Danner, Frederick
In order to understand the process of reading, it is important to determine how strings of letters are perceived. This study tests the hypothesis that units of visual perception may include pairs of letters and perhaps even high-frequency, monosyllabic trigrams (three-letter sequences). Participants were asked to report the names of either single letters or trigrams, which were presented tachistoscopically. The trigrams were of varying text frequency and had either one or two syllables. Although letters were perceived more rapidly and more accurately than were trigrams when the interval between stimulus and mask onsets (stimulus onset asynchrony, or SOA) was longer (65 or 125 msec), perception of single letters was no more accurate nor faster than high-frequency monosyllables at the briefest SOA (50 msec). These data are taken as evidence that frequent syllables can, under some circumstances, be perceived as holistic units. (Author)
