Demonstrates that the theoretical principles developed by Tversky and his colleagues in the context of similarity judgments are not restricted to this domain but hold for comparative judgments in general. Contributes to the exploration of the cognitive processes that underlie responses in survey interviews. English Preface by Norbert Schwarz. Text in German
