| Περίληψη: | The internet is the primary source of information about a broad range of topics, which may range from consumer and medical decisions to political and socio-scientific issues. The relevant information is often available in the form of written texts that convey divergent perspectives, such as different opinions, competing theoretical assumptions, arguments and counterarguments, and evidence and counterevidence. What are the challenges and potential problems associated with comprehending texts that convey multiple perspectives? How can students be supported to make the most of this obviously complicated reading situation? This chapter attempts to answer these questions from a particular theoretical perspective that revolves around the notion that readers routinely validate text information against pertinent and accessible knowledge and beliefs. We will discuss how validation acts in concert with the two other major component processes of text comprehension, activation and integration. This discussion will be followed by an outline of the Two-step Model of Validation, a model that makes predictions about circumstances that enable or hinder readers to form a coherent and consistent mental representation out of multiple perspectives.
