Outlines a theory of metaphor that posits varying levels of semantic processing and formalizes the levels in terms of kinds of semantic mapping operators. Predicted complexity of semantic mapping operators was tested using metaphor interpretations of 204 children aged 6-12 years and 24 adults. Processing score increased predictably with age. (SAK)

Three studies investigated second-, fourth-, and sixth-grade students' understanding of class inclusion hierarchies and the relationship of such understanding to the ability to construct external representations for hierarchically structured information. Children understood hierarchical relations and relations expressed in tree diagrams as early…

Two intra-modal immediate repetition priming experiments ask whether speech inputs can link directly to abstract underlying representations, or whether access is mediated via intervening "access representations" of each word's surface phonetic form. (Author/VWL)

Reports two sets of lexical priming experiments in which the morphological, semantic, and orthographic relationships between primes and targets are varied in three SOA conditions. Results showed that morphological structure plays a significant role in early visual recognition of English words that is independent of both semantic and orthographic…

Argues that the lexical production system takes a compositional approach to processing morphologically complex forms in cases of productive word formation even if the semantics of the word cannot be derived formally from the meaning of its constituents. Evidence is presented from a case of acquired naming impairment in a patient whose ability to…

Introduces this issue of the journal, summarizing current issues in spoken word recognition. Argues a full understanding of the process of lexical access during speech comprehension will depend on resolving several issues: what is the form of the representations used for lexical access; how is phonological information coded in the mental lexicon;…

Semantic influences on attention during the 1st fixation on a scene were explored in 3 experiments. Subjects viewed briefly presented scenes; following scene presentation, a spatial probe was presented at the location of an object whose identity was consistent or inconsistent with the scene category. Responses to the probe served as an index of…

Retrieving the answer to a general knowledge question has been shown to involve two metacognitive processes--a feeling-of-knowing that initiates the search of long-term memory and a willingness to continue searching until an answer can be confidently stated. To extend this model, college students were asked to retrieve as many members of 2 natural…

This article deals with two main topics: the interplay of iconicity and metaphors in signed language discourse and the relevance of sociocultural knowledge for a full understanding of LIS metaphors. In metaphors, the iconic features of signs play a role in the creative process of determining a mental fit between two different domains. Iconicity…

This paper presents the Featural and Unitary Semantic Space (FUSS) hypothesis of the meanings of object and action words. The hypothesis, implemented in a statistical model, is based on the following assumptions: First, it is assumed that the meanings of words are grounded in conceptual featural representations, some of which are organized…

N400 is an event-related brain potential that indexes operations in semantic memory conceptual space, whether elicited by language or some other representation (e.g., drawings). Language models typically propose three stages: lexical access or orthographic- and phonological-level analysis; lexical selection or word-level meaning and associate…

A group of 73 normal children (ages 8 to 10) was compared to 49 age-matched developmentally dyslexic children of average intelligence on the California Verbal Learning Test for Children (CVLT-C), to determine if reading disability was associated with impaired verbal memory. Dyslexics differed significantly from controls on 9 of the 12 CVLT-C…

Presents evidence that young children's comprehension of the locatives "in", "on", and "under" is, at least in part, contextually determined. Children were given tasks with verbal instructions which were either contextually congruent or incongruent. Results are interpreted in terms of the non-linguistic as well as linguistic strategies apparently…

A theory of comprehension in verification tasks is developed from a general conception of language comprehension. Models are developed for a task involving transfer verbs "borrow" and "loan" and the possession verb "have." Models and theoretical framework are superior in some respects to constituent comparison and conversion models. (CHK)

Research is reported in which a memory-for-marked-semantic-features theory was juxtaposed to a memory-for-meaning theory. The results were interpreted as supporting a global memory-for-meaning theory. (Author/RM)
