Abstract

Pragmatic language impairment is closely related to the executive function difficulties in patients with acquired brain injury(ABI). This study was designed to explore the correlation between two domains following ABI. Thirty-five participants with ABI were grouped into 21 aphasics due to stroke and 14 TBIs. All subjects were over 55 years old. Measures of two domains were administered to all participants. As a result, figurative language comprehension and functional/symbolic language were significantly correlated with the activating task in aphasic group. All tasks were significantly correlated in TBI group. Aphasic patients' figurative language comprehension significantly predicted the activating task. In TBI group, figurative language expression and functional/symbolic language were the predictable tasks of planning and activating, respectively. Current study demonstrates the evidence of a significant association between pragmatic language and executive function, and provides appropriate tasks used for cognitive-linguistic intervention of individuals with ABI.

후천성 뇌손상(ABI) 환자의 인지-언어 능력은 하위 영역 간 상호작용의 맥락에서 고려되어야 하는데, 특히 화용언어는 통합적 인지 처리를 관장하는 집행기능과 직결된다. 본 연구에서는 ABI 환자를 대상으로 화용언어와 집행기능 간의 상관성을 규명하고자 하였다. 이를 위해 만 55세 이상의 ABI 환자군 35명(뇌졸중에 의한 실어증 21명, TBI 14명)을 대상으로 화용언어와 집행기능 관련 5개 하위 과제를 평가하였다. 그 결과, 실어증 집단은 비유언어 이해 및 기능/상징언어가 실행화 과제와 유의한 상관성을 보였고, TBI 집단은 모든 과제 간에 유의한 상관성이 있었다. 실어증 집단의 비유언어 이해는 실행화, 그리고 TBI 집단의 비유언어 표현과 기능/상징언어는 각각 계획화와 실행화를 가장 잘 예측하는 과제였다. 본 연구를 통해 ABI 이후의 인지-언어적 중재 시 상호 보완적으로 활용할 수 있는 화용언어 및 집행기능 과제들을 제시할 수 있었다.
