Semantic as opposed to acoustic encoding in STM

Abstract

The Ss were given triads of consonants or words in the Peterson and Peterson situation. After PI had been built up for the CCCs the Experimental group was given a word trigram such as Pea, Kay, Bee and the Control group received the homophonic triad P, K, B. A significant improvement in performance was shown for the Experimental group and none for the Control It is concluded that semantic factors override any acoustic factors which might operate in this type of STM situation. © 1968, Psychonomic Journals.
