The ability to allocate attentional resources to relevant aspects of a stimulus event is a critical skill needed for efficient information processing. Evidence suggests that this ability to focus on relevant information without interference is dependent on the nature of the stimulus structure of the information to be processed. To test the…

Human working memory can be defined as a component system responsible for the temporary storage and manipulation of information related to higher level cognitive behaviors, such as understanding and reasoning (Baddeley, 1992; Becker & Morris, 1999). Working memory, while able to manage a complex array of cognitive activities, presents with an…

The conditions under which explicit instruction in checking, combined with worked examples, may be beneficial in learning how to translate sentences into algebraic equations was examined from the perspective of cognitive load theory. In two experiments it was shown that Grade 8 and 9 students were initially disadvantaged by the inclusion of a…

Three experiments investigated the conditions under which redundant verbal information would facilitate a listener's performance. Kindergarteners, first graders, and fourth graders were asked to select which of several groups of pictures a message (either redundant or constructive) described. Verbal redundancy was found to facilitate only older…

Two experiments investigated the effects of four teaching treatments on sixth graders' learning of an ecology curriculum. Recitation was more significant in improving learning than the other treatments--probing or followup questioning; redirection of a question to another student; and higher cognitive questioning.

Impromptu speech is characterized by the simultaneous processes of ideation (the elaboration and structuring of reasoning by the speaker as he improvises) and expression in the speaker. Other elements accompany this characteristic: division of speech flow into short segments, acoustic relief in the form of word stress following a pause, and both…

A study investigated the process of information extraction in reading in order to determine whether language constraints in texts reduced the amount of visual detail noticed by the reader during the reading of specific words. A detailed examination was made of 20 college students' eye movement patterns as they read a group of selected passages.…

Cloze procedure, a testing method which systematically deletes words in written prose and then measures the accuracy of the information is reviewed from a historical viewpoint. Redundancy is placed in a verbal context and can be noted on three separate levels of language: (1) surface syntactic structure; (2) deep syntactic structure; and (3)…

A study was conducted to determine if increasing the redundancy of sections in scientific articles where typical readers became bored or confused would have a desirable effect on other readers. Undergraduate journalism students applied R. F. Carter's signalled stopping technique to two different science articles by indicating points where they…

This book, uniting the material from numerous lectures on communication theory, is designed to serve as the introduction to a series entitled "Studies in Communication," which will appear during the next few years. It is not intended for the expert in each of the many fields related to human communication, but, rather, it is designed for the…

A study was conducted into the operation of an interactive-compensatory model of reading. Specifically, it examined the development of context-free word recognition skills, their role in contextual reading, and the degree to which one word recognition skill might compensate another. Four word factors were examined: (1) orthographic redundancy (the…

This article hypothesizes that language repetition of young children (in the sense used by Kobashigawa and Snow) does not help language acquisition. The evidence comes from the results of a prior study in which no indication was found that mothers who repeat themselves a great deal have children who acquire language more quickly. However,…

The idea of reducing the redundancy of a verbal message in a statistical way is presented as a practiced technique of language testing. Considering the temporality of speech comprehension, and the necessarily sequential intake of information, these cues may include the serial order of elements and transitional probability. To give the background…
