A Markov model was proposed to account for the short-term retention of the spatial arrangement of letters. The model was fit to three spatial location recall conditions in experiments which differed in distractor task. The rate of information transfer from primary to secondary memory was affected by changes in distractor task. (SW)

Two experiments investigated the relationship of verification to the answering of yes-no questions. Subjects verified simple statements or answered simple questions. Various proposals concerning the relative difficulty of answering questions and verifying statements were considered, and a model was proposed. (SW)

Five experiments were conducted that illustrate microprocesses of discourse comprehension related to foregrounding. An intermediate case in which prior memories exist but must be reinstated to active memory was studied in detail. (SW)

A phoneme confusion matrix consisting of 1,620 spontaneous speech errors was analyzed. It is shown that there is no tendency for linguistically unmarked consonants to replace marked consonants and that sound segment errors almost always involve the movement of unitary segments and not the movement of component distinctive features.
