Social information processing theory has been posited as a description of how mental operations affect behavioral responding in social situations. Arsenio and Lemerise (this issue) proposed that consideration of concepts and methods from moral domain models could enhance this description. This paper agrees with their proposition, although it…

Metadata is often created in a time-consuming process by catalogers, digital library technicians, and others. It is then underused in the systems. But recent experiments by some library organizations indicate that only the surface is being scratched on what data can do. The American West Project at the California Digital Library (CDL) is…

Valid assessment with diverse populations requires tools that are not influenced by cultural elements. This study investigated the relationships between culture, information processing efficiency, and general cognitive capacities in samples of Caucasian and Mexican American college students. Consistent with the neural efficiency hypothesis,…

The number of children and adolescents accessing the Internet as well as the amount of time online are steadily increasing. The most common online activities include playing video games, navigating web sites, and communicating via chat rooms, email, and instant messaging. A theoretical framework for understanding the effects of Internet use on…

This research explores the way in which young children (5 years of age) and adults use perceptual and conceptual cues for categorizing objects processed by vision or by audition. Three experiments were carried out using forced-choice categorization tasks that allowed responses based on taxonomic relations (e.g., vehicles) or on schema category…

According to the feelings-as-information account, a person's mood state signals to him or her the valence of the current environment (N. Schwarz & G. Clore, 1983). However, the ways in which the environment automatically influences mood in the first place remain to be explored. The authors propose that one mechanism by which the environment…

A multiagent connectionist model is proposed that consists of a collection of individual recurrent networks that communicate with each other and, as such, is a network of networks. The individual recurrent networks simulate the process of information uptake, integration, and memorization within individual agents, and the communication of beliefs…

A literature review of the development of the information technology (IT) curriculum in recent decades in Hong Kong reveals that the aim of the curriculum has shifted from Computer Studies to the development of information literacy (IL).

Distance education created new challenges regarding the delivery of large size isochronous continuous streaming media (SM) objects. In this paper, we consider the design of a framework for customized SM presentations, where each presentation consists of a number of SM objects that should be retrieved and displayed to the user in a coherent…

This paper presents a research study that explored the nature of the cognitive preferences of school administrators. It offers insight into the school administrators' mode of information processing. The first of three sections concerns the informational centrality of school principals. Citations from the literature are used to present the ways…

A new method of bus route scheduling uses aerial photography and computer data analysis. Maps generated in this manner can be used with other information to study housing/population patterns, attendance boundaries, and the like. (Author/IRT)

Author analyzed the cognitive systems of different peoples and suggested that having diverse means of acquiring information increased the chances that a culture and its institutions would survive. (Editor/RK)
