Visual Imagery for Letters and Words. Final Report.
Weber, Robert J.
In a series of six experiments, undergraduate college students visually imagined letters or words and then classified as rapidly as possible the imagined letters for some physical property such as vertical height. This procedure allowed for a preliminary assessment of the temporal parameters of visual imagination. The results delineate a number of visual image phenomena: (1) visual image sequencing and formation is guided by implicit speech when long unpronounceable letter strings are used; (2) when short pronounceable words are used, the entire string can be simultaneously represented in visual imagination, and implicit verbal control is required; (3) the capacity of the visual image system is very limited--between three to five letters for short easily pronounceable letter strings; and (4) visual image and visual percept representations of words are comparable for very short pronounceable letter strings, but as the length of the string increases visual image capacity for simultaneous representation is soon exceeded.
