This paper reviews the aspects of cognitive science that relate best to using electrical and magnetic recording to understand the function of brain systems. It outlines a framework for relating cognitive activities of daily life (typing, reading) to underlying neural systems. The framework uses five levels of analysis: task, elementary operations,…

Hearing-impaired speechreaders use linguistic context to compensate for the poor visibility of some speech movements. Constraints on spoken language enhance speechreading performance and help compensate for the paucity of sensory data. The largest effects come from linguistic constraints imposed by sentence context--syntactic, semantic, and…

Dynamic visual acuity (DVA) is defined as the performer's ability to visually discriminate parts of an object when there is relative motion between the target and the performer. According to research findings, this visual attribute may play a key role in motor-task performance. Researchers have found a significant relationship between DVA and…

From the perspective of reading specialists, factors contributing to reading difficulties include visual and auditory limitations, instructional and environmental problems, and emotional difficulties. A hierarchy of word recognition skills is presented. The usefulness of diagnosing children learning disabled or dyslexic is examined in the context…
