Acquired prosopagnosia without word recognition deficits.
It has long been suggested that face recognition relies on specialized mechanisms that are not involved in visual recognition of other object categories, including those that require expert, fine-grained discrimination at the exemplar level such as written words. But according to the recently proposed many-to-many theory of object recognition (MTMT), visual recognition of faces and words are ca...
متن کاملWord and text processing in acquired prosopagnosia.
OBJECTIVE A novel hypothesis of object recognition asserts that multiple regions are engaged in processing an object type, and that cerebral regions participate in processing multiple types of objects. In particular, for high-level expert processing, it proposes shared rather than dedicated resources for word and face perception, and predicts that prosopagnosic subjects would have minor deficit...
متن کاملCovert recognition in acquired and developmental prosopagnosia.
BACKGROUND Some patients with prosopagnosia have covert recognition, meaning that they retain some familiarity or knowledge of facial identity of which they are not aware. OBJECTIVE To test the hypothesis that prosopagnosic patients with right occipitotemporal lesions and impaired face perception lack covert processing, whereas patients with associative prosopagnosia and bilateral anterior te...
متن کاملEmotional attention in acquired prosopagnosia.
The present study investigated whether emotionally expressive faces guide attention and modulate fMRI activity in fusiform gyrus in acquired prosopagnosia. Patient PS, a pure case of acquired prosopagnosia with intact right middle fusiform gyrus, performed two behavioral experiments and a functional imaging experiment to address these questions. In a visual search task involving face stimuli, P...
متن کاملAnalytic Word Recognition without Segmentation
Nowadays, the real tendency in handwriting recognition is oriented towards the analytical approach. For such orientation the letter model learning quality is primordial. Consequently, it is needed to reduce the human intervention in this processing phase in order to limit the initial bias. Currently, the analytical approaches are divided into two categories depending on the use or not of the se...
