“…The parenthetical phrases, in most cases, may be considered to constitute a form of 'formulaic language' which may be particularly vulnerable in individuals with RHD (e.g., Van Lancker, 2004) 5 , thus providing a possible alternative account of the somewhat surprising difficulty experienced by listeners with these sentences. It has also been proposed that processing of proper nouns may be more impaired subsequent to RHD (Van Lancker & Ohnesorge, 2002), whereas common nouns may be more affected by LHD. Upon close inspection, it is evident that more proper nouns appear in the non-integrated versions of the appositive stimuli and the integrated versions of the tag stimuli-precisely those conditions in which perceptual errors were greatest for the RHD speakers' productions.…”

The present investigation focussed on the neural substrates underlying linguistic distinctions that are signalled by prosodic cues. A production experiment was conducted to examine the ability of left-(LHD) and right-(RHD) hemisphere damaged patients and normal controls to use temporal and fundamental frequency cues to disambiguate sentences which include one or more Intonational Phrase level (IPh) prosodic boundaries.Acoustic analyses of subjects' productions of three sentence-types -parentheticals, appositives, and tags -showed that LHD speakers, compared to RHD and normal controls, exhibited impairments in the control of temporal parameters signalling phrase boundaries, including inconsistent patterns of pre-boundary lengthening and longer-thannormal pause durations in non-boundary positions. Somewhat surprisingly, a perception test presented to a group of normal native listeners showed listeners experienced greatest difficulty in identifying the presence or absence of boundaries in the productions of the RHD speakers. The findings support a cue lateralization hypothesis in which prosodic domain plays an important role.

“…Similarly, Van Lancker and Nicklay (1992) found that two people with global aphasia comprehended personally familiar names better than non-personal words, and one of the people studied by Saetti et al (1999) could name relatives and friends well, despite a much greater difficulty with contemporary famous people. Findings such as these have generated the view that the right hemisphere might contribute to the processing of personal items (e.g., see Van Lancker & Ohnesorge, 2002). Interestingly, the one participant in this study who failed to show an advantage for personally relevant vocabulary had right hemisphere damage.…”

“…Similarly, impairments in person-specific semantics are typically associated with right hemisphere damage (e.g., Kitchener & Hodges, 1999;Thompson et al, 2004), although see Miceli et al (2000) for an exception to this rule. Visual field experiments show that although common and proper nouns have a right visual field/left hemisphere advantage, this is smaller for proper nouns (Ohnesorge & Van Lancker 2001; see also Van Lancker & Ohnesorge 2002). In an attempt to reconcile such contradictory findings, Thompson et al (2004) suggest that processing of person-specific semantic knowledge depends primarily on right temporal regions, while general semantic knowledge depends more on the left.…”

Processing proper nouns in aphasia: Evidence from assessment and therapy

et al. 2004

Background: Dissociations between proper and common names following brain damage have frequently been reported (see Yasuda, Nakamura, & Beckman, 2000, for review) and suggest that these different word classes are processed by distinct mechanisms. The dissociations are often observed in people with relatively pure impairments, but might also be expected more generally in aphasia. There is the further possibility that the different vocabulary groups require different therapy approaches. Yet, to our knowledge, no study has explored whether treatments that are known to be successful with common nouns are also successful with proper nouns. Aims: This study had two main aims: to compare the comprehension and production of common and proper nouns in 20 people with aphasia; and to investigate whether semantic naming therapy is equally effective for common and proper nouns. Methods & Procedures:A total of 20 people with aphasia were tested in their ability to comprehend and produce matched sets of proper and common nouns. The stimuli comprised: 20 famous people, 20 famous places, 20 high-familiarity common nouns, and 20 lowfamiliarity common nouns. Participants were also tested with personally relevant proper names, such as the names of family members. In the second phase of the study 10 of the original participants were given semantic therapy for both common and proper nouns. Experimental measures explored effects on treated and untreated words. Outcomes & Results: Initial testing found that comprehension scores were generally high, with no word class effect. In production, proper nouns were significantly more difficult to name than the matched common nouns. However, this finding excluded personally relevant proper nouns, which were the most successfully named items. Results from the second phase showed that semantic therapy was equally effective in improving naming of both common and proper nouns. As in many previous studies, effects were almost entirely confined to treated items. Conclusions: Our findings suggest that proper nouns induce more naming failures in aphasia than common nouns. However, despite this, they seem equally amenable to therapy. Clinical and theoretical implications are discussed.

“…The NFT distribution in our patient suggests the possibility of corticocortical disconnection of the frontal lobes from parietal or temporal areas that may have contributed to the occurrence of RP by disrupting brain circuits that link parietal or temporal areas responsible for place recognition and for similarity and familiarity matching to frontal lobe regions [10,14,15], or connections between closely located areas in the right temporal lobe which are required for the visual recognition of faces and scenes [2,8].…”
