This response to Brainerd and Reyna's paper (in this issue) argues that the common resources hypothesis can be applied to a wider range of phenomena than can the output-interference hypothesis. Presents results of a dual-task experiment under bidirectional deficits. Concludes that dual-task studies do not provide critical tests of the resources…

Explains exploratory sequential data analysis (ESDA) and outlines ESDA characteristics that could help human-computer interaction investigators using sequential data make better conceptual and methodological choices. Behavioral, cognitive, and social factors are considered, and failures of expertise, time management, and databased problems are…

Examines a model for children's strategies for inclusion tasks. Suggests that young children are not consistent in task strategies and that they display mixed response strategies. Strategies may change with development. (ET)

Explains how indexers choose keywords and how results can differ between indexers by focusing on certain properties of the terms rather than on the terms themselves. Based on research in semiotics, cognitive science, discourse analysis, and reading theories. Indexing terms from 833 bibliographic records from an environmental database are analyzed.…

Focuses on the interpretation of research data of Berthier, Starkstein, Lylyk, and Leiguarda (1990) reporting a case of faster recovery, after selective sodium amytal injection, of the patient's second language than his native language. Paradis (1990) argued that these results do not support Ojemann and Whitaker's (1978) hypothesis. (five…

Interest regarding neural information processing in autism is growing because atypical perceptual abilities are a characteristic feature of persons with autism. Central to our review is how characteristic perceptual abilities, referred to as "perceptual signatures," can be used to suggest a neural etiology that is specific to autism. We review…

Three experiments were conducted that provide a direct examination of within-category discontinuity manipulations on the implicit, procedural-based learning and the explicit, hypothesis-testing systems proposed in F. G. Ashby, L. A. Alfonso-Reese, A. U. Turken, and E. M. Waldron's (1998) competition between verbal and implicit systems model.…

Recent research has indicated a link between retrieval-induced forgetting and the production of misinformation effects (J. Saunders & M. D. MacLeod, 2002). The mechanism underlying this relationship, however, remains unclear. In an attempt to clarify this issue, the authors presented 150 participants with misinformation under conditions designed…

This study tested the hypothesis that memory is a major source of variance in temporal processing. Participants categorized intervals as short or long. The number of base durations and interval types mixed within blocks of trials varied from 1 session to another. Results revealed that mixing 2 base durations within blocks increased categorization…

Two processes have been hypothesized to underlie improvement in perception: attunement and calibration. These processes were examined in a dynamic touch paradigm in which participants were asked to report the lengths of unseen, wielded rods differing in length, diameter, and material. Two experiments addressed whether feedback informs about the…

Observers often miss the 2nd of 2 visual targets (first target [T1] and second target [T2]) when these targets are presented closely in time; the attentional blink (AB). The authors hypothesized that the AB occurs because the attentional response to T2 is delayed by T1 processing, causing T2 to lose a competition for attention to the item that…

In today's knowledge economy, technology is utilized more than ever to deliver instructional material to the learner. Nonetheless, information may not always be presented in a manner that maximizes the learning experience, resulting in a negative impact on learning outcomes. Drawing on the Task-Technology Fit model, a research framework was…

The schema theory of comprehension as it relates to understanding while reading is reviewed in this report. Several techniques for the study of on-line measurement of comprehension are described that are based on a series of ten stories, each with two versions. The report notes that when subjects were asked to generate interpretations of stories…

The primary purpose of this study was to determine empirically whether an individual's cognitive style differentially influences his hypothesizing behavior within a relatively simple information processing task. A characteristic of cognitive style explored is the manner in which an individual perceives and analyzes a stimulus configuration;…

This study explores how an individual's cognitive style influences the development of a strategy in a concept identification task and how an individual tests his hypotheses in a concept learning set task. Subjects for the research were given the Hidden Figures Test as a means of identifying their cognitive styles. Half of the subjects were…
