This issue investigates the functions of interrogative speech acts in cognition regarded as a distributed, culture-based process. The first article by Borchmann, Mortensen & Tranekjær is an introduction to the theme. The subsequent eleven articles are grouped into three sections under three themes.
Class, form and function includes three articles addressing issues related to classification and analysis of questions and identification of stable relations between form and function: Niels Møller Nielsen; Simon Borchmann; Johannes Heim & Martina Wiltschko.
Multifunctionality and context comprises five articles, four identifying and describing genre-specific, interaction type-specific or activity-crossing functions of questions, and one focusing on deceptive or evasive answers from a verbal as well as non-verbal analytical perspective: Louise Tranekjær; Patricia Mayes & Mary Clinkenbeard; Rita Finkbeiner; Winnie Collin; Dawn Archer
Systems, variation and change includes three articles suggesting or adopting a global perspective on questioning sequences, and accounting for the relation between the local and the global level of dialogical systems that serve specific purposes: Eva-Maria Graf, Frédérick Dionne & Thomas Spranz-Fogasy; Sune Sønderberg Mortensen; Line Brink Worsøe & Thomas Wiben Jensen.
