Right Hemisphere Brain Damage

This study examined the generality of a previous finding indicating that difficulty suppressing or inhibiting context-inappropriate interpretations is an important predictor of narrative discourse comprehension for adults with right brain damage RBD) (C. A. Tompkins, A. Baumgaertner, M. T. Lehman, & W. Fassbinder, 2000). Forty adults with RBD and 39 without brain damage listened to two-sentence stimuli and judged whether a probe word fit with the overall stimulus meaning. An ambiguous initial sentence elicited both dominant and less preferred inferences, and the second sentence resolved the ambiguity toward the initially less-likely interpretation. Probes represented the dominant inference for the first sentence and were presented at two poststimulus intervals. Probe judgment response times indicated that neither group suppressed the eventually inappropriate inferences in the time intervals studied. However, multiple regression analysis demonstrated that for individual participants with RBD, the extent of suppression from one interval to the next was a significant predictor of performance on a specialized measure of inference comprehension. The discussion evaluates these findings and identifies directions for future research.

Right Hemisphere Brain Damage

Normal comprehension skill is linked with the proficiency of a suppression mechanism, which functions to dampen mental activation that becomes irrelevant or inappropriate to a final interpretation. This study investigated suppression and discourse comprehension in adults with right brain damage (RBD). To index suppression function, 40 adults with RBD and 40 without brain damage listened to sentence stimuli that biased the meaning of a sentence-final lexical ambiguity (e.g., SPADE), then judged whether a probe word (e.g., CARDS) fit the overall sentence meaning. Probes represented the contextually inappropriate meanings of the ambiguities and were presented in two conditions: 175 ms and 1000 ms poststimulus. The same probes were used with unambiguous comparison stimuli. Probe judgment response times indicated that only the group without brain damage suppressed inappropriate interpretations over time. In a multiple regression analysis, suppression function added significantly to predicting performance on a general measure of narrative discourse comprehension for participants with RBD. The discussion addresses how suppression deficits may account more broadly for comprehension difficulties after RBD; it also considers several unresolved issues concerning the suppression construct and the suppression deficit hypothesis.

Predictive inferencing was evaluated in 13 adults with right hemisphere damage (RHD) and 11 adults without brain damage (NBD). Brief narrative stimuli that strongly suggested a single outcome were constructed to vary recency of mention of inference-related information. Reading times were recorded for narrative-final sentences that disconfirmed the target inferences. Slowed reading time on the final sentences was an indicator of inference generation. Adults with RHD generated target predictive inferences in contexts with recent mention of strongly biasing inference-related information. This group also evidenced maintenance of inferences over time, but to a lesser degree than participants in the NBD group. Overall, individuals with better auditory comprehension or larger estimated working memory capacity tended to maintain inferences better than did the other participants. The results are discussed in relation to current hypotheses of inferencing and discourse comprehension in adults with RHD.

Right Hemisphere Brain Damage

Evidence conflicts as to whether adults with right hemisphere brain damage (RHD) generate inferences during text comprehension. M. Beeman (1993) reported that adults with RHD fail to activate the lexical-semantic bases of routine bridging inferences, which are necessary for comprehension. But other evidence indicates that adults with RHD activate multiple interpretations in various comprehension domains. In addition, the activation of contextually inappropriate interpretations is prolonged for many adults with RHD and predicts poor discourse comprehension. This study contrasted Beeman's activation failure hypothesis with the prediction that adults with RHD would generate multiple interpretations in text comprehension. The relation between activation of textually incompatible inferences and discourse comprehension was also investigated for this group. Thirty-seven adults with RHD and 34 without brain damage listened to brief narratives that required a bridging inference (BI) to integrate the text-final sentence. This final sentence, when isolated from its text, was strongly biased toward a contextually incompatible alternate interpretation (AI). Auditory phoneme strings were presented for lexical decision immediately after each text's initial and final sentence. Adults with RHD were both faster and more accurate in making lexical decisions to BI-related target words in final-sentence position than in initial-sentence position. Thus, contrary to the activation failure hypothesis, adults with RHD generated the lexical-semantic foundations of BIs where they were required by the text. AI generation was evident in accuracy data as well, but not in response time data. This result is partially consistent with the multiple activation view. Finally, greater activation for contextually incompatible interpretations was associated with poorer discourse comprehension performance by adults with RHD.

The Subject

Abstract The relations between the emotions and the brain's functioning have been the subject of scientific investigation over the past decade. This report continues this investigation in a single case study that required the subject to evoke different emotional states (happiness, love, depression) and rate the emotional states on an intensity scale while brain activity was monitored by quantitative electroencephalography (QEEG). The variations in brain activation patterns in these evoked emotional states indicated a predominant QEEQ activation of the beta2 (32–64 Hz) frequency range for all emotional states, with specificity of left hemisphere and temporal lobe activation for happiness and right hemisphere for depression. The response pattern also indicated a greater activation of central and posterior locations for the emotional states.

Right Hemisphere Brain Damage

Narrative discourse is investigated in clinical and healthy populations. This study explored the discourse strategies used to tell stories, comparing the patterns of people with left- and right-hemisphere brain damage, as well as healthy speakers. We analyzed picture-elicited discourses by four people with aphasia, two people with right hemisphere damage, and four healthy speakers. We examined their microlinguistic properties, as well as macrolinguistic features, such as the discourse production type of utterances and patterns of story component usage. We identified two storytelling strategies used by the speakers: a narrative strategy marked by a prevalence of narrative discourse production type utterances and scarce use of evaluation clauses, and a quasi-narrative strategy with the opposite pattern. These strategies were used by both healthy speakers and participants with brain damage
