title: Peripheral aspects of writing can be differentially affected by sensorial and attentional defect: evidence from a patient with afferent dysgraphia and case dissociation.
abstract: This study reports a patient with right posterior cerebral atrophy who was affected by afferent dysgraphia, characterised by case dissociation: cursive better than upper-case print. The patient also had severe visuocostructional deficit and simultanagnosia. The hypothesis advanced to explain this dissociation is that cases are not equally dependent on visual and kinaesthetic control. Thus, if visual and kinaesthetic feedback (or the attention to them) are impaired by cerebral lesions, upper case can be expected to be more impaired than cursive.
