本研究旨在评估单侧右脑损伤(RHD)如何影响词义隐喻方面的知识和加工。在听觉词汇判断任务中，可以表达隐喻意义或字面意义的歧义形容词被用作目标词。目标之前有有效的(与目标的隐喻或字面意义相关的)、中性的或无关的质数。在两种注意条件下呈现了初始-目标对，旨在有利于相对自动或相对费力的心理处理，并收集了反应时间数据。风湿性脑病中风患者在自动状态下的表现与左脑损伤和正常对照组相似，当被给予特定的加工策略时，表明他们保留了一些隐喻词义的知识。然而，当让他们自己收集策略时，两组大脑受损的人都遇到了困难。这些结果和RHD文献中的其他结果从注意资源容量和注意分配模型的角度进行了讨论。
This study was designed to assess how unilateral right hemisphere brain damage (RHD) affects the knowledge and processing of metaphoric aspects of word meaning. Ambiguous adjectives that could convey either a metaphoric or a literal meaning were used as target words in auditory lexical decision tasks. Targets were preceded by primes that were valid (related to the target’s metaphoric or literal meaning), neutral, or unrelated. Prime-target pairs were presented in two attention conditions, designed to favor either relatively automatic or relatively effortful mental processing, and reaction time data were gathered. RHD stroke patients performed similarly to left-brain-damaged and normal control subjects in the automatic condition, and when provided with specific processing strategies, indicating that they retained some knowledge of metaphoric word meanings. When left to glean strategies for themselves, however, both brain-damaged groups had difficulty. These results and others from the RHD literature are discussed in terms of attentional resource capacity and attentional allocation models.
