Abstract 摘要
This study aimed to prove that counterfactual reasoning was accessible without contextual cues in Chinese, further demonstrating developmental differences in mastering counterfactuality in this language. This study challenged the traditional view that counterfactual thinking is exclusively available through discourse in conversational Chinese due to the lack of a subjunctive mood. It was argued that without morphological inflections, Chinese counterfactual reasoning could be reached through unique coercive tactics with negative linguistic expressions. The sentence-verification paradigm (Carpenter and Just, 1975) was employed to probe counterfactual comprehension by comparing mental representations of contrary-to-fact sentences. It was predicted that successful counterfactual reasoning would be observed in these coercions. Meaning-based representations would be formed in mental models, rather than structural ones. Because of the discrepancy between linguistic form and meaning in counterfactuals, extra time was required to process counterfactual clauses. The results confirmed the predictions. It was concluded that the same cognitive concept is reached in distinct linguistic ways. Developmental differences in mastering Chinese counterfactual reasoning were observed, and the function of negation in Chinese counterfactuals was discussed.

本篇论文研究主旨以心理语言学实验法找到处理中文假设语气的证据,论证说明以中文为母语的使用者具有不需言谈脉络线索的推理能力,此外,研究也找到推理能力在发展上的差异。传统观点认为由于中文缺乏虚拟语气的构词句法结构,与过去事实相反假设语气思维只在具有充足推理线索的言谈会话中出现,这篇研究透过词汇与句法结合,加上否定词的使用,成功表达与过去事实相反的推理语意。实验采用语句确认典范(Carpenter and Just, 1975)透过比较语句的心智表征测试与过去事实相反语气的理解。研究预期受试者完全了解与过去事实相反的假设语气意义,形成以语意为基础的心智表征而非语法结构为主的表征,且处理与过去事实相反假设语气的反应时间比起表达事实的语句更长。得到的结果与预期相符,说明相同的认知行为可以藉由不同的语言表达方式达成,更进一步由不同年龄层受试者证明中文与过去事实相反假设语气语句处理的差异。文中对中文否定词在假设语气中的功能也有进一步的讨论。
