Abstract The level of metaphor comprehension and interpretation was investigated in a sample of children with cleft palate (CP), aged 6;0-8;11, and healthy controls matched with age, sex, socioeconomic status, and IQ level. The Wechsler Intelligence Scale for Children - Revised (WISC-R) was used to evaluate the children’s cognitive functioning, and the metaphor tests from a modified version of the Right Hemisphere Language Battery - Polish version (RHLB-PL) were used to assess comprehension of figurative language. The CP and control groups differed significantly in Verbal IQ values and in performance in the Vocabulary test, Comprehension test, Picture Metaphor Explanation test, and Written Metaphor Explanation test. In both metaphor explanation tests, children with CP gave fewer responses than controls. The results suggest no differences between children with CP and controls in understanding figurative language, although they point to weaker performance in communicating responses and producing statements in the CP children group.

Abstract Great emphasis has been placed on the right hemisphere, due to its possible selective contribution, in the processing of metaphorical statements. Objectives: To describe the processing of metaphors in the case of a patient with transcortical motor aphasia, using specific tests for patients with encephalic injuries of the right hemisphere, and to contribute to the discussion on the inter-hemispheric relationships associated with this function. Methods: A 54 year-old man with transcortical motor aphasia was evaluated three years after a left hemisphere stroke. The tasks of comprehension of metaphors were based on the subtest Metaphor Comprehension Task of the Montreal Evaluation of Communications Scale (MEC). Two metaphor comprehension tests were applied, in 45-minute sessions with a 48 hour interval between each. Test 1 involved comprehension of the metaphors according to the options offered, and Test 2 the comprehension of metaphors measured by response time and visual field. Results: Although the right hemisphere was not affected by the stroke in this case, difficulties were observed in the processing of metaphors. Conclusions: This study suggests that the left hemisphere participates in the processing of figurative meanings. The adaptability of the brain can also re-accommodate the uninjured areas of the brain, causing the dynamic of the brain to be modified. As a result, deducing cerebral functions based on clinical data can be problematic. The value of this study is that it can contribute to clinical aspects of language rehabilitation.

The Right

The neurotypical brain is characterized by left hemisphere lateralization for most language processing. However, the right hemisphere plays a crucial part when it is required to bring together seemingly unrelated concepts into meaningful expressions, such as in the case of novel metaphors (unfamiliar figurative expressions). The aim of the current study was to test whether it is possible to enhance novel metaphor comprehension through an easy, efficient, and non-invasive method – intentional contraction of the left hand’s muscles, to activate the motor and sensory areas in the contralateral hemisphere. One hundred eighteen neurotypical participants were asked to perform a semantic judgment task involving two-word expressions of four types: literal, conventional metaphors, novel metaphors, or unrelated, while squeezing a rubber ball with their right hand, left hand, or not at all. Results demonstrated that left-hand contraction improved novel metaphor comprehension, as participants were more accurate and quicker in judging them to be meaningful. The findings of the present work provide a simple and efficient method for boosting right hemisphere activation, which can be used to improve metaphoric language comprehension. This method can aid several populations in which right hemisphere function is not fully established, and who struggle with processing figurative language, such as adolescents and individuals on the autistic spectrum.

Abstract The study assessed the quantity and quality of errors made by schizophrenia patients in understanding and interpretation of the same metaphors, to evaluate metaphor understanding and explanation depending on the type of presentation material, and to analyze the correlation of illness symptoms with metaphor comprehension and explanation. Two groups of participants were examined: a schizophrenia sample (40 participants) and a control group (39 participants). Metaphor processing was assessed by the subtests of the Polish version of the Right Hemisphere Language Battery (RHLB-PL). The patients were also evaluated with the Positive and Negative Syndrome Scale (PANSS). Schizophrenia patients scored significantly lower in explanation of metaphors, making more incorrect literal and abstract mistakes or providing no answer more frequently. No differences were observed in understanding metaphors; no correlation between symptoms and metaphor processing was obtained. In both groups, picture metaphors were easier to comprehend and written metaphors were easier to comprehend than to explain.
