The superiority of learner-paced over system-paced instructions was demonstrated in multiple experiments. In these experiments, the system-paced presentations were highly speeded, causing cognitive overload, while the learner-paced instructions allowed adjustments of the presentational flow to the learner's needs by pacing facilities, mostly…

We present a developing distributed cognition theory of interdisciplinary collaboration that incorporates concepts from both situated cognition and information processing theory. This theoretical framework is being refined as it is used for analyzing interdisciplinary collaboration within the National Institute of Science Education (NISE). The…

The technique for examining the time course of information processing developed by D. E. Meyer et. al. (1988) is analyzed. Research is provided, which suggests that this new method gives important qualitative support to some stochastic models and quantitative support to the continuous diffusion model of information processing. (SLD)

Reading is a process that bridges the distinction between perceptual and cognitive processes but the formalisms of the information processing approach to the study of reading apply most naturally either to models assuming a series of noninteracting stages of information processing or to a set of independent parallel processing units. This paper…

Argues that anticipating communication has cognitive tuning effects such that individuals think descriptively and entertain a greater variety of thoughts when they anticipate receiving information, but think valuatively and avoid information searches when they perceive they will primarily convey rather than receive information in a forthcoming…

Describes a classroom technique that promotes higher levels of thought and enhances learning in graduate and undergraduate teacher education classes. (DF)

Discusses the meaning crisis in modern society in terms of information overload. Points out reasons for meaning lag: (1) slowness of meaning formation; (2) sparseness of social networks; (3) substitution of meaning of a lower quality as a compensation for lost meaning; and (4) information becoming noiselike. (PD)

In reply to "Educational Foundations for Tomorrow's Information Scientists" (Bulletin of ASIS, June/July 1989), which identifies 10 key concepts as educational foundations for information science, it is argued that paradigms found in computer science education and the dimension of human information processing further complicates the…

Focuses on delineating ways of knowing in nursing, with particular attention to the process of scientific discovery and clinical judgment. (JOW)

Examined how information-processing load affects the writing process by having 40 undergraduates write a short essay up to a supplied ending sentence with increasing content constraints. Results found that a high information-processing load led to lower-rated story coherence, but not to lower- rated quality. (36 references) (MDM)

Viewing television requires mental effort. Among the findings in this study, results indicated that more mental effort was required to process simple video and auditory information than complex information because the cognitive system is activated to a higher degree by complex messages and thus processes information more efficiently. (PD)

Investigates performance of 8, 10, 12 year olds and adults on cognitive tasks in terms of several processing-speed measures, each of which may change independently with age. Results underscore the complexity of developmental change in processing efficiency. (Author/RH)

Theoretical/empirical foundations on which reaction times are measured and interpreted are discussed. Models of human information processing are reviewed. A hybrid procedure and analytical framework are introduced, using a speed-accuracy decomposition technique to analyze the intermediate products of rapid mental processes. Results invalidate many…

This study investigated the problem representations formed by college students while solving mathematics problems. Problem representation characteristics indicative of understanding were identified by analyzing audio-tapes and written work of sixteen subjects, ages 16 to 24, who solved mathematics problems using the think-aloud technique. These…

In the pair of experiments reported here the authors investigated the relationship between meaningfulness of problem statements and subjects' use of these statements in problem-solving tasks. Subjects (96 university students) were required to memorize meaningful formulae such as "volume = area x height" or corresponding symbolic formulae such as…
