The author considers the problem of creating images, namely its psychological and ontological aspects. Based on the assumption that mental representation is not a mimetic reproduction of objective reality, but a reference to mutually imputed collective knowledge, the author discusses various factors of this situation. The concept proposed by the author is based on presumption that the measure of the...
The reconciliation of theories of concepts based on prototypes, exemplars, and theory‐like structures is a longstanding problem in cognitive science. In response to this problem, researchers have recently tended to adopt either hybrid theories that combine various kinds of representational structure, or eliminative theories that replace concepts with a more finely grained taxonomy of mental representations...
The measurement, or at least the estimation, of the operators’ workload is an important aspect of usage-oriented design of professional systems. Various approaches to the a priori measurement of workload have been proposed. They can be classified into three categories: performance measures, physiological measures and subjective measures. Subjective methods have many advantages such as high ‘face validity’,...
The measurement of the operators’ workload is an important aspect of usage-oriented design of professional systems. In domains such as avionics, air traffic management or mission systems, being able to quantify the operators’ workload under stress, and in potentially demanding physical and mental conditions, is mandatory to anticipate overload and prevent human errors. Current approaches to workload...
Maps, graphs, and diagrams use simplified graphic forms, like lines and blobs, to represent basic spatial relations, like boundaries and enclosures. A schema is an iconic representation where perceptual detail has been abstracted away from reality in order to provide a more flexible structure for cognition. Unlike truly symbolic representations of spatial relations (i.e., prepositions) a schema preserves...
