In humans, the visual sense is the most important of the five senses, and a lack of it poses serious limitations, both in daily life activities and also in job placement. The most basic task enabled by the visual system is the navigation of spatial environments. More advanced...

متن کاملSelective visual streaming in face recognition: evidence from developmental prosopagnosia.
Computational considerations suggest that efficient face identification requires the categorization and exclusive streaming of previously encoded face visual primitives into a dedicated face recognition system. Unique evidence supporting this claim is provided by a rare case of developmental pure prosopagnosia with otherwise normal visual and cognitive functions. Despite his normal visual memor...
متن کاملImpaired integration of emotional faces and affective body context in a rare case of developmental visual agnosia.
In the current study we examined the recognition of facial expressions embedded in emotionally expressive bodies in case LG, an individual with a rare form of developmental visual agnosia (DVA) who suffers from severe prosopagnosia. Neuropsychological testing demonstrated that LG's agnosia is characterized by profoundly impaired visual integration. Unlike individuals with typical developmental ...
