Presents study designed to further evaluate the nature of spoken-language comprehension under conditions of varying perceptual load by manipulating different comprehension conditions. Investigates effects of subsidiary task paradigms on course of simultaneous comprehension processing. Argues that these can only be used when accompanied with probes…

Discusses the cognitive processes involved in constructing linear orderings from pairwise relationships of information items. Examines the effects that sentence types used in presenting information have on these processes, and tests two models designed to clarify the acquisition of spatial knowledge and the processing of locative and comparative…

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)

This study examines two views of lexical storage and word production, a derivational hypothesis and an independent unit hypothesis. Reaction times and errors were related to derivational complexity. A model of lexical retrieval process incorporating derivational processes is proposed. (Author/SW)

Examines, through an investigation of the effect of word frequency on lexical decision, alternative views of how the internal lexicon is structured and searched. A model is developed based on two internal lists: one a ready-access list, the other a complete list. (Author/AM)

Describes an experiment to test two assumptions concerning what is stored in the memory with regard to sentence structure: (1) that the linear effect observed is based on a tally model rather than on an integrationist mechanism; (2) that this linear effect is not uniquely the result of a mechanism operating at comprehension.

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)

Discusses a sequential, three-stage model of how nonliteral expressions are understood, as proposed in recent linguistic, philosophical, and psychological studies. Testing the model's implication that nonliteral meanings of sentences are ignored whenever literal meanings are plausible, finds evidence that both meanings are processed simultaneously…

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.
