The development of mathematical marking conventions from prehistory to the present is characterized by a trend from conventions with more iconic relationships to concrete structures of the physical world (such as more pictorial ancient land surveying marks) to marking systems with less-iconic relationships to physical structures (that represent numbers, operations, infinity, and other more abst...

Iconic memory, the short-lasting visual memory of a briefly flashed stimulus, is an important component of most models of visual perception. Here we investigate what physiological mechanisms underlie this capacity by showing rapid serial visual presentation (RSVP) sequences with and without interstimulus gaps to human observers and macaque monkeys. For gaps of up to 93 ms between consecutive im...

This study reports on an experiment examining the impact of iconic graphics on participants’ understanding of domains represented by entity relationship diagrams. Cognitive load theory and the cognitive theory of multimedia learning are used to hypothesize that iconic graphics reduce the cognitive load of model viewers, leading to more complete mental models and consequently improved understand...

This paper presents a study of iconic gestures as attested in a corpus of Greek face-to-face television interviews. This study takes place in an interactional context that is different from the narrative genre that has been primarily examined so far regarding the semantics and the communicative significance of the iconic gestures. We attempt to classify the iconic gestures attested according to...

Bimodal bilinguals are hearing individuals fluent in a sign and spoken language. Can the two languages influence each other such despite differences visual (sign) vocal (speech) modalities of expression? We investigated cross-linguistic influences on bimodal bilinguals’ expression spatial relations. Unlike languages, uses iconic linguistic forms that resemble physical features objects relation ...

We present a conceptual framework and a process model for feature extraction and iconic visualization. The features are regions of interest extracted from a data set. They are represented by attribute sets, which play a key role in the visualization process. These attribute sets are mapped to icons, or symbolic parametric objects, for visualization. The features provide a compact abstraction of...

In this paper an iconic notation for describing the composition between the relations of a new qualitative representation model based on trajectories in two dimensions is presented. This qualitative representation model represents a new intuitive approach for describing the spatiotemporal features of two mobile entities through the relations between its trajectories. In order to describe the co...
