Investigates the effects of linguistic context, more particularly, semantic context in the form of an incomplete sentence, on the ability of observers to classify letter strings as words or nonwords. (Author/RK)

The duration and timing of the context is which letters occur is shown to influence the perceptibility of the target in experiments demonstrating that early on enhanced word presentations and pronounceable-pseudoword contexts increase letter perceptibility. The perceptibility of letters in strings sharing several or few letters with words is…

Experiments tested the predictions that words are perceived more accurately in strongly constraining word contexts than in weakly constraining word contexts, and that a strong perceptual advantage would be present for letters in words vs. letters alone or in unrelated-letter strings. Several alternative theories of word perception are discussed.…

High frequency words typed in normal and alternating case were presented tachistoscopically in the fovea and parafovea to children and adults. Dependent measures were percentages of letters and words correct. Few differences between age groups were found. Serial position curves also showed similarities across grades in the parafoveal information…

Orthographic context and visual letter information were independently varied in a letter recognition task. The results contradicted the qualitative predictions of nonindependence theories of reading and are accurately described by a quantification of independence theory. (Author/CP)

Schuberth and Eimas (EJ 159 939) reported that context and frequency effects added to determine reaction times in a lexical decision (word v nonword) task. The present reexamination shows that context and frequency do interact, with semantic context facilitating the processing of low-frequency words more than high-frequency words. (Author/CP)

In this study, eight groups of kindergarten children were trained to discriminate position and order differences in verbal and nonverbal item sequences in the context of a matching task or an associative learning task or both. Transfer was measured by having the subjects sight learn a list of words contrasting in position and order. Subsequently,…
