Discusses the role of visualization of information in learning. Theorizes that the comprehension of visualizations is a process of structure mapping between a visuo-spatial configuration and a mental model. Tests the model and finds differences in the use of text and picture information to answer different kinds of text questions. (DSK)

Experiments explored the hypothesis that immediate memory span varies with length of recalled words. Relationships between memory and word length, temporal duration, reading speed and visual and auditory presentation were investigated. Results are interpreted in terms of a phonemically-based store of limited temporal capacity with varied…

G. Wolford's perturbation model of letter identification is designed to account for identification errors of briefly presented characters. Its chief assumptions are that features are extracted in parallel, that some of these features become perturbed or mislocalized, and that mislocalizations are more likely to occur in the direction of the fovea…

Three experiments use a tachistoscopic word recognition task to investigate how skilled readers covert visual input into a speech-related or phonological code during reading. (Author/NCR)
