Based on the communication literature, telepresence is defined as “a mediated experience that creates for the user a strong sense of presence and entails an illusion of non-mediation”. The main body of previous studies serves industrial communication where technology is of vital concern. However, in the context of e-commerce, the appropriate focus of telepresence should be the human experience ...

The goal of Intelligence Augmentation (IA) is the development of tools that improve the efficiency of human intelligence. To this end, the authors of this chapter introduce a model of human conceptualization on the basis of a cognitive theory of information processing and a Peircean theory of signs. An account of two experiments is provided. The first concerns conceptualization by individuals, ...

This paper focuses on one aspect of a research study exploring the cognitive processes of decision making by 11 nurse practitioners and 11 general practitioners from the south east of England, using six patient scenarios during 2000. It sets out to explain some of their decision-making processes. This paper is part of a larger study discussing the use of information processing theory as a frame...

A model is proposed in which stochastic choice results from noise in cognitive processing rather than random variation in preferences. The mental process used to make a choice is nonetheless optimal, subject to a constraint on available information-processing capacity that is partially motivated by neurophysiological evidence. The optimal information-constrained model is found to offer a better...

A growing number of information technology systems and services are being developed for persuasive purposes, i.e. to change users’ attitudes or behaviour or both. This paper proposes a taxonomy of general persuasive approaches, with interpersonal, computer-mediated and human-computer persuasion as the key types. It also recognizes and briefly describes related theories from social psychology, n...

DEFINITION Information foraging theory [9] provides scientific predictions and explanations of information-seeking behavior in human-computer interaction (HCI). It also provides engineering models for designing and evaluating information systems and their user interfaces. Information foraging theory assumes that people adapt their information-seeking behavior to maximize their rate of gaining u...

In this article, the author reviews three traditions of cognitive assessment: the structural approach (based on factor analytic research), the information – processing approach, and the dynamic approach (based on learning theory). The theoretical background of each assessment approach is sketched and the advantages and disadvantages of each discussed. The author then processes an integrated two...
