Pragmatics is appropriate use of language across a variety of social contexts that provides accurate interpretation of intentions. The occurrence of the right hemisphere lesions can interfere with pragmatic abilities, and particularly with the processing of nonliteral speech acts.
Since the objective of this study was to assess different aspects of pragmatic competence in the right hemisphere damage (RHD) patients, 20 Iranian patients with right hemisphere lesions were examined by adult pragmatic profile (APP) and a novel checklist was introduced for Persian language speaking individuals. Meanwhile, 40 healthy adult individuals, who were age and gender matched with RHD patients, were considered as the control group. After obtaining video records, all subjects were evaluated for 35 pragmatic skills, including 24 verbal, 5 paralinguistic, and 6 nonverbal aspects, by a two-point scale system.
Studying RHD patients and their healthy counterparts revealed that the performance by participants with right hemisphere lesions exhibited a high degree of inappropriate pragmatic abilities compared with controls in all domains. Furthermore, RHD patients showed a trend of increasing difficulty in understanding and producing different pragmatic phenomena, including standard communication acts.
Present results indicated that the right hemisphere lesions significantly affected pragmatic abilities in verbal, paralinguistic and nonverbal aspects. Such a pattern of performance, which is in line with deficits previously reported for RHD, proved the unquestioned role of the right hemisphere in processing nonliteral language.
语用学是指在各种社会情境中对语言的恰当运用,它能准确诠释意图。右半球损伤的出现会干扰语用能力,尤其是对非字面言语行为的处理。
由于本研究的目的是评估右半球损伤(RHD)患者语用能力的不同方面,对20名患有右半球损伤的伊朗患者进行了成人语用概况(APP)测试,并为说波斯语的个体引入了一份新的清单。同时,将40名年龄和性别与RHD患者匹配的健康成年人作为对照组。在获取视频记录后,通过两点量表系统对所有受试者的35种语用技能进行评估,包括24种言语、5种副语言和6种非言语方面。
对RHD患者及其健康对照者的研究表明,与对照组相比,右半球损伤参与者在所有领域的语用能力表现出高度的不恰当性。此外,RHD患者在理解和产生不同语用现象(包括标准交流行为)方面呈现出困难增加的趋势。
目前的结果表明,右半球损伤在言语、副语言和非言语方面显著影响语用能力。这种表现模式与先前报道的RHD缺陷一致,证明了右半球在处理非字面语言方面的毋庸置疑的作用。
