“…In conclusion, the results of the present investigation are consistent with our previous studies which have carefully manipulated levels of context use and processing demands (Leonard & Baum, 1998;Leonard et al, , 1997a, and suggest that the claim that the RH is specialized for the processing of contextual information and therefore that RHD individuals have difficulty using context to process language (e.g. Cook & Beech, 1990) is a far too simplistic and ill-defined notion.…”

A word-monitoring task was conducted with a group of right-hemisphere-damaged (RHD) patients and a group of nonbrain-damaged control (NC) participants under three attention conditions—isolation, focused attention, and divided attention—to address the hypothesis that individuals with RHD experience difficulty in the use of contextual information under conditions that tax processing resources. Following Leonard et al. [Leonard, C. L., Baum, S. R., & Pell, M. D. (2001). The effect of compressed speech on the ability of right-hemisphere-damaged patients to use context. [...] These findings support those of Leonard et al. and suggest that individuals with RHD are, indeed, able to use certain types of contextual information in language processing even under conditions of reduced processing resources. The results are discussed in relation to potential processing distinctions between structural and nonstructural contexts

“…In support of this claim, recent studies have shown that RBD patients do not always have problems with text-level tasks (e.g., Leonard & Baum, 1998;Leonard et al, 1997aLeonard et al, , 1997b. At the same time, there are studies documenting left-frontal patients' deficits for processing language in context (Channon & Crawford, 2000;Ferstl, Guthke, & von Cramon, 1999;Kaczmarek, 1984;Novoa & Ardila, 1987).…”

Comprehending language in context requires inferencing, particularly for the establishment of local coherence. In the neurolinguistic literature, an inference deficit after right hemisphere brain damage has been postulated, but clinical observation and imaging data suggest that left-frontal lesions might also result in inference deficits. In the present experiment, 25 nonaphasic patients performed a coherence judgment task requiring them to indicate a pragmatic connection between 2 successively presented sentences. Patients with left-temporal or right-frontal lesions performed the task well. In contrast, patients with left-and bifrontal lesions exhibited the most severe deficit. Both error rates and response times were elevated for coherent trials as compared with incoherent trials. These results confirm that the leftfrontal lobe contributes to inference processes.

“…Nicholas and Brookshire (1986;see also, Brookshire & Nicholas, 1984;Wegner, Brookshire, & Nicholas, 1984) found that RHD adults were not impaired in answering questions regarding the main ideas of texts when compared to NBD controls and LHD patients, but were impaired in answering questions relating to propositions not explicitly stated in the text. Other researchers have also questioned the general idea that processing contextual information is disrupted following RHD (Cannito, Jarecki, & Pierce, 1986;Hough, Pierce, & Cannito, 1989;Leonard, Waters, & Caplan, 1997a;Leonard, Waters, & Caplan, 1997b;Tompkins, 1990Tompkins, , 1991aTompkins, Boada, & McGarry, 1992). Leonard et al (1997a,b), for instance, found that RHD adults utilized biased sentence contexts to resolve ambiguous pronouns to the same degree as neurologically intact and LHD controls.…”
