| Abstract: | Investigated whether words made up of probable letters and probable letter combinations are more accurately recognized than words made up of improbable letters and improbable letter combinations. The experimental method corrected shortcomings in previous research which has shown accuracy of word recognition to be affected only by word probability and not by letter probability. The shortcomings were the confounding of different letter probability dimensions within one another. In the present investigation with 40 19-43 yr old adults, 100 words were assessed with respect to the probabilities of their letters and, independently, the conditional probabilities of their letters. Subsequent tests of recognition accuracy in a brief presentation showed accuracy to be greatest for words made up of letters having either high simple probabilities or high conditional probabilities. It is concluded that word recognition is an active, perhaps serial, process which makes liberal use of individual letter statistics to facilitate accurate recognition.
