Two experiments are described. One measured performance of subjects on pairs of concurrent verbal tasks, monitoring sentences for certain items while reading. Secondary task performance combined with a primary task is proportional to its performance in isolation. The second experiment checked certain results of the first. (CHK)

Investigated children's understanding of meaning of the cognitive verb "know" (as defined by an abstractness and conceptual difficulty hierarchy). Found that knowledge increased with development, and low levels of meaning were mastered before high levels, and more rapidly. Understanding in audio-taped stories was more difficult than in video-taped…

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)

A theory of the components of verbal intelligence is developed and tested in this series of experiments. After reviewing alternative theoretical frameworks for understanding verbal intelligence, a componential theory of verbal comprehension is proposed. This theory specifies the information-processing components, context cues, and mediating…

Discusses evidence that social understanding informs word learning in infants. Asks: (1) Is genuine social understanding necessary for word learning?; (2) Are social clues criterial for infants' learning?; (3) Can word learning proceed without aid of social understanding?; and (4) Is social clue processing too difficult for everyday word learning?…

Chapter 1 describes the children and their families, chapter 2 discusses the…
