此前对普及性发展障碍(PDD)患者的研究表明,他们在理解比喻语言方面存在困难。本研究采用分裂视野范式,考察了23名PDD成人和24名典型发育(TD)成人对习语和反讽的大脑半球加工。结果表明,患有PDD的成年人在理解比喻语言方面相对没有受到损害。TD组在处理习语的非显著意义和段落的反讽结尾方面表现出右脑优势,而PDD组则以双侧的方式处理这些刺激。我们的发现表明,在患有PDD的成年人中,大脑偏侧化是不典型的。成功的表现以及双侧大脑的激活表明,PDD组使用了一种补偿机制。
Previous studies on individuals with pervasive developmental disorders (PDD) have pointed to difficulties in comprehension of figurative language. Using the divided visual field paradigm, the present study examined hemispheric processing of idioms and irony in 23 adults with PDD and in 24 typically developing (TD) adults. The results show that adults with PDD were relatively unimpaired in understanding figurative language. While the TD group demonstrated a right hemisphere advantage in processing the non-salient meanings of idioms as well as the ironic endings of paragraphs, the PDD group processed these stimuli bilaterally. Our findings suggest that brain lateralization is atypical in adults with PDD. Successful performance along with bilateral brain activation suggests that the PDD group uses a compensation mechanism.
