“…Consequently, selective conceptual impairments for other proper names, similar to those reported in APA for conspecifics, are not expected. If these names are thought of as pure referential expressions, however, their selective disruption might result from damage to knowledge of the components of arbitrary semantic links (Semenza, 1997;Semenza & Zettin, 1988, 1989. The performance reported for subject DK (Incisa della Rocchetta et al, 1998) is consistent with this view.…”

As a consequence of a head trauma, APA presented with selective anomia for the names of familiar people, in the absence of comparable disorders for common names and other proper names. Face recognition was normal; and naming performance was unaffected by stimulus and response types. Selective proper name anomia was not due to effects of frequency of usage or of age of acquisition, or to selective memory/learning deficits for the names of people. Even though APA was able to provide at least some information on many celebrities whom she failed to name, she was clearly impaired in all tasks that required full conceptual information on the same people (but she performed flawlessly in similar tasks that involved common names). This pattern of performance indicates that in our subject the inability to name familiar persons results from damage to conceptual information. It is argued that detailed analyses of conceptual knowledge are necessary before it is concluded that a subject with proper name anomia suffers from a purely output disorder, as opposed to a conceptual disorder. The behaviour observed in APA is consistent with the domain-specific hypothesis of conceptual organisation (Caramazza & Shelton, 1998), and in this framework can be explained by assuming selective damage to knowledge of conspecifics. The anatomo-clinical correlates of our subject's disorder are discussed with reference to recent hypotheses on the neural structures representing knowledge of familiar people.

“…As reviewed earlier, lesions that cause people's name deficits are broadly distributed. Nonetheless, it is noteworthy that most lesions suggested are located either`deep' or`marginal' (Semenza 1997) in the LH. It may be possible to assume that neuropsychological and anatomical connections among these areas may contribute to the processing of people's names.…”

Proper names are of practical importance for verbal communication. For instance, they are indispensable for transmission of autobiographical information concerning a person. Recent studies have revealed that proper names are neuropsychologically and anatomically processed in a manner that differs from the processing of common nouns. The current review described proper names, which are labels attached to referents, as being without semantic meaning. The clinical data are presented regarding comprehension and retrieval of people's names, and memory of their unique properties. The validity of a cognitive neuropsychological model of people's name processing is also evaluated.The review suggests that after the initial memory consolidation of a name and a person by the left hemisphere's hippo/parahippocampus, the memory become established in the adjoining fusiform gyrus. Consequently, it is hypothesized that the fusiform gyrus forms a processing network for people's names with the temporal pole and postero temporo/occipital lobe. The research on geographical names, topographical names, and therapeutic approaches for deficits of proper names is also reviewed.

“…Surprisingly little research has examined the ability to identify proper names from the visual presentation modality. By way of contrast, the ability to retrieve proper names corresponding to photographs has been examined extensively in aphasia, and selective impairment of this capacity has been linked with damage to the left temporal lobe (Harris & Kay, 1995;McKenna & Warrington, 1980;Papagno & Capitani, 1998;Semenza, 1997;Semenza & Zettin, 1989;Verstichel, Cohen, & Crochet, 1996). Data from GP indicate that, unlike the ability to recall proper names from memory, the ability to recognize proper names from the visual modality is not abolished as a result of large-scale damage to the temporal lobe of the LH.…”
