Landi, Nicole; Perfetti, Charles A. – Brain and Language, 2007
The most prominent theories of reading consider reading comprehension ability to be a direct consequence of lower-level reading skills. Recently however, research has shown that some children with poor comprehension ability perform normally on tests of lower-level skills (e.g., decoding). One promising line of behavioral research has found…

Reichle, Erik D.; Perfetti, Charles A. – Scientific Studies of Reading, 2003
In reading research, morphological processing and monomorphemic word identification have generally been treated separately. We describe a computational model that brings both kinds of reading together within a single framework. This model assumes that word knowledge-the orthography, phonology, and meaning of words-accumulates with experiences with…

Perfetti, Charles A.; Beck, Isabel – 1982
There are at least two kinds of phonetic knowledge: phoneme synthesis and analytic knowledge. In phoneme synthesis a person demonstrates phonetic knowledge by being able to assemble segments into larger units. With analytic knowledge one knows that syllables or words are analyzable into constituent segments. One type of knowledge enables learning…

Hogaboam, Thomas W.; Perfetti, Charles A. – Journal of Educational Psychology, 1978
Three experiments examined the relationship between reading skill and decoding. Children decoded and matched words and pseudowords of different syllable lengths presented in both aural and printed form. Prior verbal experience was manipulated. Decoding differences were not wholly attributable to prior experience with word units, as processes…

Perfetti, Charles A.; And Others – Journal of Educational Psychology, 1978
Vocalization latencies of young readers were a function of set size, number of syllables, and stimulus material. Differences between skilled and less skilled readers were absent for naming colors, digits, and pictures, but present for words; differences increased with number of syllables (and letters). Reading skill and decoding are discussed.…

Perfetti, Charles A.; And Others – Memory & Cognition, 1979
Word identification latencies and word prediction accuracy were compared for groups of skilled and less skilled fifth grade readers in three experiments. In each experiment, discourse context reduced identification latencies for less skilled as well as skilled readers. This was true both when context was heard and when it was read. The general…

Bell, Laura C.; Perfetti, Charles A. – Journal of Educational Psychology, 1994
Highly skilled and less skilled college readers (n=29) were compared on several information-processing and language-comprehension tasks that tap cognitive components of reading. Results confirm that both areas distinguish skilled and less skilled readers and suggest that reading ability is a continuous function. (SLD)

Perfetti, Charles A. – 1983
One model of interactive processing useful in describing word identification processes in discourse context is of a weakly interactive type. This type assumes that the time to identify a word in context is an activation function, whereas the time to activate a word in memory beyond some criterial identification threshold is a multiplicative…

Perfetti, Charles A.; McCutchen, Deborah – 1986
The notion that a set of restricted-generalized abilities underlies both reading and writing is explored in this essay. Following a definition of schooled language competence (SLC), the first section asserts that knowledge and problem solving are insufficient and nonlinguistic approaches to language competence. The second section focuses on…

Perfetti, Charles A. – 1983
Reading encompasses a wide range of verbal processes, among them such simple verbal processes as word decoding, letter recognition, name retrieval, and semantic access. The question is whether simple verbal processing differences are adequate to account for general reading ability differences. Across different verbal domains and different ages,…
