This report summarizes research on experienced programmers' comprehension of computer programs that was carried out over a three-year contract period (1982-85). Following an extensive review of the programming skill literature, an analysis of programs based on the multiple abstractions (points-of-view) that characterize program text and design was…

The first of three articles on the ways in which people formulate their observations, this paper considers the basic assumptions of both syntactic and paradigmatic models of cognition and their applications in natural (i.e., human) and artificial (i.e., computer) information processing. The analysis begins with background information on the nature…

A study examined the efficacy of the keyword method of vocabulary instruction by comparing it with five methods designed to increase semantic processing of the definitions of the vocabulary words. Subjects in all five experiments were college students. In the first three experiments, recall of the definitions from the vocabulary words was the…

This paper describes and illustrates a simulation model for the processing of grammatical elements in a sentence, focusing on one aspect of sentence comprehension: the assignment of the constituent elements of a sentence to the correct thematic case roles. The model addresses questions about sentence processing from a perspective very different…

Seventy good readers and 70 poor readers who were students at a community college participated in a study that examined the role of adversative connectives in helping students integrate information across sentence boundaries. Three functions of adversative connectives were examined: contrast or conflict, parallel points, and foregrounding…

A study investigated language patterning, as an indication of synthetic mental activity, in comparison groups of normal pre-middle-aged adults (30-42 years), normal elderly adults (75-93), and elderly adults (71-91) with Alzheimer's dementia. Semiotic theory was used as the conceptual context. Linguistic measures included the Token Test, the…

Issues in syntactic processing, that aspect of the human sentence comprehension mechanism that recovers a syntactic structure for a given word string, are discussed. In particular, two structural ambiguities in Mandarin Chinese are examined and their successful parsing within the framework of minimal parsing models is discussed. Recent work…

A study investigated whether very young children use the concept of mutual exclusivity to make an initial link between a word and an object, and whether its use is linked to age or intelligence differences. Three groups of normally-developing children, aged 1 to 3 years, and three groups of older, mildly retarded children with similar levels of…

Investigates the metalinguistic ability of monolingual or bilingual children between five and nine years of age on two language tasks (grammaticality judgment and correction). (HOD)

Two experiments tested claim that transparency of Korean fraction names promotes fraction concepts. Findings indicated that U.S. and Korean first- and second-graders erred similarly on a fraction-identification task, by treating fractions as whole numbers. Korean children performed at chance when whole-number representation was included but…

Three studies of language comprehension skills compared 9- and 10-year-old learning-disabled children (LDC) with difficulty retaining verbal information (n=8) with LDC with normal memory spans (n=8) and normally achieving children (n=16). LDC did not have significant impairments in listening comprehension. However, LDC may experience difficulties…

Examined whether superior mathematics performance of students from Japan, Korea, and China may be due, in part, to differences in cognitive representation of number affected by Asian language features. Results suggested that the unique characteristics of the Asian number language system may facilitate the teaching and learning of mathematics,…

In two experiments, mothers told their infant and an adult a story that involved target words, and women taught an assembly procedure involving novel terminology to another adult. In speech to infants, mothers positioned focused words on pitch peaks, but in speech to adults, the emphasis was more variable. (BC)

Phonetic skills and vocabulary size were investigated in 37 toddlers identified with specific expressive language impairment and 20 comparison toddlers. Results indicate significant differences in numbers of consonant types and tokens, although the most frequently present consonants were consistent across groups. No predictive relationship emerged…

A study examined central auditory processing ability of 15 children with attention-deficit hyperactivity disorder (ADHD), 15 children with ADHD and learning disabilities (LD), and 15 controls. Results indicated lower central-auditory-processing ability and significant correlations between reading and ADHD and reading and…
