  abstract  = {Background: Discourse abilities play an important role in the assessment, classification, and therapy outcome evaluation of people with aphasia. Discourse production in aphasia has been studied quite extensively in the last 15 years. Nevertheless, many questions still do not have definitive answers.Aims: The aim of this review is to present the current situation in the research on a number of crucial aspects of discourse production in aphasia, focusing on methodological progress and related challenges. This review continues the discussion of the core themes in the field, aiming to render it as up-to-date as possible.Main Contribution: The review focuses on a number of unexplored theoretical issues, specifically, the interface between micro- and macrolinguistic abilities, and the relationship between linguistic competence and communicative success in aphasia. The emphasis on theoretical challenges, along with the thorough discussion of methodological problems in the field, makes this review a starting point and a comprehensive information source for researchers planning to address language production in people with aphasia.Conclusion: Although the picture is not yet complete, recent advancements lead to a better understanding of the processes involved in aphasic discourse production. Different approaches provide insights into the complex multifaceted nature of discourse-level phenomena; however, methodological issues, including low comparability, substantially slow down the progress in the field.},

  abstract  = {Objective: How do patients with severe aphasia perform in the clock test? Methods:Ten patients with severe aphasia performed the clock test in two modes: copy a given clock (copy condition) and set a clock by drawing the clock hands, where a given digital display (11:10) should be transformed into an analogue display (time setting condition). Results: Not a single patient with severe aphasia was able to master any mode of the clock test. Both copy and time conditions were severely impaired by executive, conceptual, motoric visuospatial and apraxic disorders - impairments of language system were only one of numerous influencing factors. Conclusions and clinical relevance:The clock test measures and requires for its execution so many different cognitive, motoric and perceptual functions that it cannot adequately differentiate between patients with severe aphasia and other severe brain damage.},
