Explorations in Cognitive Semiotics
Edited By Jordan Zlatev, Göran Sonesson and Piotr Konderak
This volume constitutes the first anthology of texts in cognitive semiotics – the new transdisciplinary study of meaning, mind and communication that combines concepts and methods from semiotics, cognitive science and linguistics – from a multitude of established and younger scholars. The chapters deal with the interaction between language and other semiotic resources, the role of consciousness and concepts, the nature of metaphor, the specificity of human evolution and development, the relation between cognitive semiotics and related fields, and other central topics. They are grouped in four sections: (i) Meta-theoretical perspectives, (ii) Semiotic development and evolution, (iii) Meaning across media, modes and modalities, (iv) Language, blends and metaphors.

Iconic Properties are Lost when Translating Visual Graphics to Text for Accessibility
Imagine a blind or low-vision individual who needs to access a graphic representation, for example a financial chart (Figure 1a). Unlike a sighted individual, who can see the actual chart, what the blind or low-vision individual accesses, usually aurally, is often its text description. Both individuals are accessing a representation of rising and falling stock prices over time. However, whereas the sighted individual sees words and undulating shapes, all the screen reader user hears are words (Figure 1d).
