Martha Farah's landmark book Visual Agnosia presented the first comprehensive analysis of disorders of visual recognition within the framework of cognitive neuroscience, and remains the authoritative work on the subject.

However, when the distractors were similar to each other and from the same semantic category his functioning decreased significantly. This associated with right-sided lesions interrupting the melodic route in the brain. Each disorder is illustrated with a clinical vignette, followed by a thorough review of the case report literature and a discussion of the theoretical implications of the disorder for cognitive neuroscience.

If someone for instance is offered a cup of hot tea and he does not recognize it as hot, he can get hurt or burned. Out Of Stock Overview The cognitive neuroscience of human vision draws on two kinds of evidence: functional imaging of normal subjects and the study of neurological patients with visual disorders.

Similarly, copying a line drawing of a beach scene led to a simplified version of the drawing, though the main features were accounted for. The most common forms are visual- seeingand auditory- hearing agnosia, but the condition can also occur with the other senses.
