In order to assess an individual for<unk> , it must be verified that the individual is not suffering from a loss of sensation, and that both their language abilities and intelligence are intact. In order for an individual to be diagnosed with<unk> , they must only be experiencing a sensory deficit in a single modality. To make a diagnosis, the distinction between apperceptive and associative<unk>  must be made. This distinction can be made by having the individual complete copying and matching tasks. If the individual is suffering from a form of apperceptive<unk>  they will not be able to match two stimuli that are identical in appearance. In contrast, if an individual is suffering from a form of associative<unk> , they will not be able to match different examples of a stimulus. For example, an individual who has been diagnosed with associative<unk>  in the visual modality would not be able to match pictures of a laptop that is open with a laptop that is closed. Pure alexia Individuals with pure alexia usually have difficulty reading words as well as difficulty with identifying letters. In order to assess whether an individual has pure alexia, tests of copying and recognition must be performed. An individual with pure alexia should be able to copy a set of words, and should be able to recognize letters. Prosopagnosia Individuals are usually shown pictures of human faces that may be familiar to them such as famous actors, singers, politicians or family members. The pictures shown to the patient are selected to be age and culture appropriate. The task involves the examiner asking the individual to name each face. If the individual cannot name whose face appears in the picture, the examiner may ask a question that would help to recognize the face in the picture.
