Imagining half the world : investigation of representational neglect with group studies and single cases
Based on ten experiments, this thesis examines representational neglect in brain damaged patients and in matched controls. The patients sometimes show a specific deficit in visual imaging: neglected one half of their mental representations. Although several studies addressed the issue of visuo-perceptual neglect, the representational defect is underinvestigated. Only a few standardized tests are available for its detention and assessment, and therefore rarely it is diagnosed in clinical practise or investigated in experimental work. In this thesis some new tests to investigate representational neglect are proposed. Moreover, representational neglect is evaluated in different sensory modalities (visual, tactile as well as within the personal domain) to address the issue of supramodality or plurimodality of this deficit.
