The effect of language on the categorical perception of color is stronger for stimuli in the right visual field (RVF) than in the left visual field, but the neural correlates of the behavioral RVF advantage are unknown. Here we present brain activation maps revealing how language is differentially engaged in the discrimination of colored stimuli presented in either visual hemifield. In a rapid,...

Is it possible to reason by means of images? If it is, then with what kind of images can we organize thoughts? How can the rules governing the relations between images be established? Could these relations be as complex and productive as those defined within the grammar of the verbal language? The basic construction of any language, especially a developed one, is a structure of formal rules whi...

Spatial language descriptions, such as The bottle is over the glass, direct the attention of the hearer to particular aspects of the visual world. This paper asks how they do so, and what brain mechanisms underlie this process. In two experiments employing behavioural and eye tracking methodologies we examined the effects of spatial language on people's judgements and parsing of a visual scene....

This paper addresses the issue of visual query formulation for temporal databases. We introduce a number of visual constructs that allow users to build queries in a modular, bottom{up fashion based on a temporal Extended Entity{Relationship Model. These constructs are: Temporal projection, temporal selection, time links, ltering and set operators, and temporal aggregates. This paper also identi...

The need to analyze and query spatial data is becoming increasingly important with the advent of applications such as Geographic Information Systems, Image Databases and Remote Sensing. The focus of our research is to support spatial data analysis by developing a direct manipulation environment to visually query as well as browse spatial data and to review the visual results for trend analysis....

Language-mediated visual attention describes the interaction of two fundamental components of the human cognitive system, language and vision. Within this paper we present an amodal shared resource model of language-mediated visual attention that offers a description of the information and processes involved in this complex multimodal behavior and a potential explanation for how this ability is...
