Read&Answer is software that mimics paper-and-pencil situations in which a reader interacts with one or more documents to perform a specific task, such as answering questions, writing an essay or similar activities. Read&Answer presents documents and questions with a mask. The reader unmasks documents and questions so that only a piece of information is available at a time. This way the entire interaction between the reader and the documents on the task is recorded and can be analyzed. To know more about Read&Answer, read Vidal-Abarca et al. (2011). Behavior Research Methods, 43, 179-192. Read&Answer generates an output that can be analyzed with RADAR.
