In the experiments outlined in this article, the authors investigate lexical access processes in language production. In their earlier work, T. Pechmann and D. Zerbst (2002) reported evidence for grammatical category constraints in a picture-word interference task. Although grammatical category information was not activated when subjects produced…

Wernicke (1900, as cited in G. H. Eggert, 1977) suggested that semantic knowledge arises from the interaction of perceptual representations of objects and words. The authors present a parallel distributed processing implementation of this theory, in which semantic representations emerge from mechanisms that acquire the mappings between visual…

Studies of patients with category-specific agnosia (CSA) have given rise to multiple theories of object recognition, most of which assume the existence of a stable, abstract semantic memory system. We applied an episodic view of memory to questions raised by CSA in a series of studies examining normal observers' recall of newly learned attributes…

Two tasks of word identification were proposed to children in their last year of upper preschool classes. The results show that identification is not based on an holistic processing but on an analytic one: some letters are enough, especially the first ones. Moreover, their order does not matter. During this period where reading is visuo-semantic…

Traditional models of human memory have postulated the need for a brief phonological or verbatim representation of verbal input as a necessary gateway to a higher level conceptual representation of the input. Potter has argued that meaningful sentences may be encoded directly in a conceptual short-term memory (CSTM) running parallel in time to…

The complexity of Chinese orthography has hindered the progress of research in Chinese to the same level of sophistication of that in alphabetic languages such as English. Also, there has been no publicly available resource concerning the decomposition of Chinese characters, which is essential in any attempt to model the cognitive processes of…

A theory of semantics focusing on relationships between meaning and sound patterns in language evolution is proposed. Using cognate sets from traditional comparative studies of closely-related languages in well-defined language families, the theory addresses the use and shifting of language components. The theory begins with the ego attempting to…

An initial description of the links between cognitive input, discourse rules, and the rules of sentence grammar is made, based on a technique developed for observing the translation of cognitive input into language in a spontaneous, practical speech event: descriptions of the lay-outs of apartments. (Author/RM)

A report is made of research designed to investigate some implications of the concept of semantic flexibility for memory. Four studies of cued recall produced evidence that interpretation of familiar, unambiguous words varied with their contexts. Considerations raised by the research are discussed. (Author/RM)

An experiment is reported which permitted the separate examination of sentence comprehension processes and subsequent sentence memory processes. The similarity between the results of comprehension and recall was discussed in terms of a retrieval process that may be similar in both tasks. (Author/RM)

The technique developed in this research paper for analyzing the information in charts and graphs is designed to reveal design flaws in the display that may prevent them from conveying information effectively. This analytic scheme requires isolating four types of constituents in a display and specifying their structure and interrelations at the…

Two types of operating principles thought to play an important role in early lexical development are discussed. The principles are those concerned with: (1) assignment of reference or meaning to words; and (2) formation and evolution of categories. Discussion also addresses related issues, such as the developmentally important relationship between…

Three studies were conducted in an attempt to replicate previous research concluding that semantic meaning is accessed in the absence of conscious awareness. A pattern mask was used to interrupt the processing of stimulus words after 30 milliseconds; at this duration subjects were not able to identify the stimulus words or even to determine…

A study examined the effect of variation in category dominance on retrieval latencies (and errors) from semantic memory. Subjects, 66 students enrolled in an introductory psychology course, were required to perform 6 successive retrievals from each of 18 conceptual categories. The six retrievals consisted of two successive blocks of three from…

Procedural semantics models have diminished the distinction between data structures and procedures in computer simulations of human intelligence. This development has theoretical consequences for models of cognition. One type of procedural semantics model, called schema theory, is presented, and a variety of cognitive processes are explained in…
