The volume explores the relationship between well-studied aspects of language (constructional alternations, lexical contrasts and extensions and multi-word expressions) in a variety of languages (Dutch, English, Russian and Spanish) and their representation in cognition as mediated by frequency counts in both text and experiment. The state-of-the-art data collection (ranging from questionnaires to eye-tracking) and analysis (from simple chi-squared to random effects regression) techniques allow to draw theoretical conclusions from (mis)matches between different types of empirical data. The sister volume focuses on language learning and processing.
