Are words read visually (by means of a direct mapping from orthography to semantics) or phonologically (by mapping from orthography to phonology to semantics)? The authors addressed this long-standing debate by examining how a large-scale computational model based on connectionist principles would solve the problem and comparing the model's…

Dyslexic students may be disadvantaged in their use of written language, impeding academic achievement, and requiring remediation and concessions. A proximal analysis assessed the operations of the 3 major pathways (orthography to semantics, orthography to phonology, and phonology to orthography) within models of reading and spelling through…

An instructional application consists of a set of resources and activities to implement interacting, interrelated, and structured experiences oriented towards achieving specific educational objectives. The development of computer-based instructional applications has to follow a well defined process, so models for computer-based instructional…

Compared to young, older adults are more likely to forget events that occurred in the past as well as remember events that never happened. Previous studies examining false memories and aging have shown that these memories are more likely to occur when new items share perceptual or semantic similarities with those presented during encoding. It is…

A personalized e-learning framework based on a user-interactive question-answering (QA) system is proposed, in which a user-modeling approach is used to capture personal information of students and a personalized answer extraction algorithm is proposed for personalized automatic answering. In our approach, a topic ontology (or concept hierarchy)…

Proposes a communication model based on a general systems-general semantics perspective in which communicators and their environments are considered as interrelated parts which continually interact with each other. (RB)

While studies of college-level readers have yielded evidence both for and against the use of phonological or speech recoding in the recognition of written words, no consistent picture of when recoding occurs has yet emerged. However, one model, the adjunct access model, can account for the previous research findings. According to this model,…

Native English speakers performed a phoneme-monitoring task to assess whether ambiguous words (homographs) require extra processing capacity under two conditions: no prior context and prior context provided by disambiguating subject-noun and verb combinations. Phoneme detection latencies were reliably longer for homographs than for control words…

Utilizes a factor analyst technique on the scores of college freshmen responding to a form of Osgood's semantic differential instrument. A three-dimensional vectorial model is constructed to explain involvement in science. (CP)

Discusses the deficiencies of the nativistic explanation of language acquisition, reviews and critiques existing theories of syntax while highlighting the trend toward a semantic description of linguistic development, and argues that a satisfactory account of language acquisition will not emerge until this process is viewed within a larger…

Describes a model that distinguishes seven types of meaning that can function in reading: discoursal, lexical, morphological, propositional, syntactic, rhetorical, and functional. (MKM)

An experiment was designed to answer the following: (1) can children as young as 2 1/2 to 3 years of age employ contextual cues in order to distinguish request from offers? and (2) do children's discrimination skills for these illocutionary acts improve with age? A model of the comprehension of illocutionary force is proposed. (Author/AM)

Discussion of software reusability focuses on classification and retrieval problems and proposes a method based on encoding semantic information to help solve those problems. Highlights include representation of semantic information; quiddity; the SRM (software resource model) and SRD (software resource diagram); and results of experiments with…

Discussion of models for indexing and searching information resources on the Internet focuses on the results of a simple query on a number of existing search systems and on two proposed index metadata structures for indexing and supporting search and discovery: the Dublin Core Elements List and the Semantic Header.

The role of prosodic breaks (PB) in the parsing of locally ambiguous noun phrases (NP) + verb (V) + NP + prepositional phrase (PP) was examined in four word-monitoring experiments. Results indicate that PBs can influence sentence parsing. The article discusses possible mechanisms in the framework of two models. (32 references) (Author/CK)
