This study investigated the role of strategy instruction and working memory capacity (WMC) on word problem solving accuracy in children with (n = 100) and without (n = 92) math difficulties (MD). Within classrooms, children in Grades 2 and 3 were randomly assigned to one of four treatment conditions: verbal-only strategies (e.g., underlining…

Reaction time and accuracy do not always reflect the same perceptual processes; therefore, the convergence of reaction time with accuracy within the context of a specific information processing model should be demonstrated empirically rather than assumed a priori. (Author/PN)

A parallel distributed processing model of visual word recognition and pronunciation is described. A key feature is the assumption that there is a simple, uniform procedure for computing a phonological representation from an orthographic representation for irregular words as well as regular words. (SLD)

Work with patients with attentional deficits produced by posterior cerebral lesions has shown that such patients can identify words correctly even when they fail to report letters in nonwords contralateral to the lesion. Because of this, it has been assumed in cognitive neuropsychology that lesions do not produce new phenomena but instead provide…

Seven studies were conducted to investigate the interactions between imagery-ability and experimental treatments that parallel instructional procedures. The general orientation of the studies was to extend the concepts of imaginal and verbal coding systems to include individual differences in symbolic habits. Thus all the studies took into account…

A study assessed the role of orthographic structure in college students' perceptual recognition and judgment of letter strings. Lexical status, word frequency, bigram frequency, log bigram frequency, and regularity of letter sequencing were orthogonally varied across a series of experiments. Six-letter words and their anagrams were used as test…

Concludes that there may be differential effectiveness of method of reading instruction according to sex, with females finding letter training simpler than word training and males finding the reverse. (FL)

Although evidence is accumulating that the major reading difficulty dyslexics experience involves decoding and recognizing printed words, it is not clear that all dyslexics read poorly for the same reasons. A study investigated dyslexic children between 7 and 14 years of age to see if their reading errors and patterns of performance would enable…

A study investigated the concept of visual memory and its relationship to the spelling process by examining the attempts of a group of Australian elementary school children to spell a selection of words containing silent consonants. Subjects, 360 second, third, and fourth grade students divided into three spelling ability groups, were given 20…

Nonverbal context is important in the language acquisition process. The present study compares different amounts and ordering of pictorial context with respect to their effect on learning word-referent relations in a second language. Twenty-five monolingual English-speaking high school students were shown twenty Spanish sentences and pictures of…

Nineteen moderately/severely retarded students (ages 9-22) completed ten 15-minute computer-assisted instruction sessions and seven basic cognitive tasks measuring simple learning, choice reaction time, relearning, probed recall, stimulus discrimination, tachictoscopic threshold, and recognition memory. Stimulus discrimination, probed recall, and…
