Prosopagnisia - created from Mind Map

Visual agnosia is the inability to recognise familiar objects presented visually. Most neuropsychologists distinguish between 'apperceptive agnosia' and 'associative agnosia'. Associative agnosia Apperceptive agnosia Associative agnosia is a failure that occurs at a later stage in the object recognition process. In contrast to apperceptive agnosias, patients with associative agnosias can draw objects, match similar objects and describe the component parts. However they cannot associate these details with stored knowledge about the objects in order to recognise them. This form of agnosia consists of a failure to recognise an object because of an inability to perceive its form. Patients are typically unable to draw the object, match objects or describe component parts.

Visual agnosias

Prosopagnosia is a condition where individuals can describe a person's face and its expressions but cannot recognise whose face it is unless they use other non-facial information such as hair, clothing or voice. A common complaint from prosopagnosics is that they have trouble following the plot of movies because they cannot keep track of the actors' identity.Research study: De Renzi and Di Pellegrino
