A study is described which examined the retrieval of regular and irregular past tense verbs. Results suggested that preterites such as "taught" are not stored as separate and independent lexical units but are formed from the verb stem by means of derivational rules. (Author/RM)

The principal recent models of semantics, conceptual, and lexical memory are explicated and criticized. A description of long-term is developed in terms of these models. (Text is in French.) (DB)

Working from theories of text grammar and logic, the authors suggest and tentatively confirm several hypotheses concerning the role of micro- and macro-structures in comprehension and recall of texts. (Text is in French.) (DB)

Reports on two experiments which question the assumption that semantic processing is superior to nonsemantic processing, and which demonstrate that effective semantic elaboration cannot be equated with the quantity of semantically congrous information. (Author/AM)

Research on educable retarded children is reviewed to explicate components of and a theory of intelligence. Studies of control processes in memory and problem solving indicate that the ability to generalize is a major component of intelligence. Research on individual differences in components of information processing systems are also discussed.…

Four possible mechanisms for short-term item recognition are distinguished. Manipulations of recency, particularly of negative probe items, provide critical tests. Two experiments were conducted using Sternberg's varied-set reaction time paradigm, coupled with procedures intended to minimize rehearsal and control the recency of probes and memory…

Four stories were divided into function word units; a dozen variables were all found to be statistically significant predictors of recall. For the more structured stories, subjects' intuitions, gist, and redundancy were the best predictors; for the less structured stories, serial position and repetition were best. (EJS)

Planning the menu for a dinner party, which involves problem-solving with a large body of knowledge, is used to study the daily operation of human memory. Verbal protocol analysis, a technique devised to investigate formal problem-solving, is examined theoretically and adapted for analysis of this task. (Author/MV)

Eight, ten, and twelve year old children were tested on a novel procedure involving the successive presentation of standard and comparision stimuli. Two hypotheses were evaluated: one dealing with memory effects, and the other with children's pretesting of choice responses in spatial information processing. (Editor/RK)

The effects of particular drugs in human memory abilities was examined. The degree of memory enhancement produced by arecholine and choline and the impairment after scopolamaine were inversely proportional to the subject's performance in placebo; that is, "poor" performers were more vulnerable to the drugs than were "good" performers. (Author/CP)

Two experiments examined the roles of semantic and surface information in reading and recognizing sentences. Results indicate that reading and recognition are interactive processes, involving conceptually driven and data driven operations; the interaction may be either automatic or controlled. Semantic and surface information are conceptualized as…

Begins by discussing a number of problems in applying a levels-of-processing approach to memory as proposed in the late 1960s and then revised in 1972 by Craik and Lockhart, suggests that some of the basic assumptions are false, and argues for information-processing models devised to study working memory and reading, which aim to explore the…

Reaction time to verify property statements was examined in the context of two semantic distance factors--typicality of the category member in the subject of the statement, and dominance of the category member's property in the predicate. (Author/NCR)

Three word-identification experiments suggest that a model derived from experiments with pseudowords can be applied successfully to word identification. The data derived from the experiments confirm the role of higher order verbal units in word identification and suggest the structural components of a verbal-mediation theory of reading. (Editor/RK)

The water jug task model was extended to four variations of the Missionaries--Cannibals river-crossing problem. Different cover stories resulted in large differences in number of illegal moves, but no difference in number of legal moves to solution. The three-stage process model explains both legal and illegal moves. (Author/GDC)
