中文摘要：

通过4个实验，考察粤语-普通话双言者与普通话单言者周期性时间推理差异。实验1和实验2表明，无论时间以5为单位、不以5为单位还是以“字”为单位，双言者反应时均比单言者长。实验3和实验4表明，当时间为以5为单位时，双言者和单言者反应时更易受奇偶次任务影响；当时间以“字”为单位时，双言者反应时更易受图形次任务影响。研究表明，语言影响时间的表征方式和推理策略。普通话单言者对周期性时间推理主要采用数字表征和加工方式，粤语-普通话双言者交替使用数字和空间表象的表征和加工方式。粤语-普通话双言者对周期性时间推理慢于普通话单言者源于时间语义表征与加工方式的弱联结。

英文摘要：

How do people represent and process cyclical time？ This is a interesting issue in the domain of time cognition. Up to now, many models have emerged, such as the Image-Word List Model advanced by Freedman. But a lot of researches have proved that the representation and processing strategies of cyclical time were affected by language and culture. A special temporal expression style in Cantonese is five minutes as ＂ a character＂. Does this kind of language expressions affect the cyclical temporal reasoning of Cantonese speakers？ This study compared the differences in cyclical temporal reasoning between Cantonese-Mandarin diglossic speakers and Mandarin speakers. Experiments 1 and 2 examined the subjects＇ cyclical temporal reasoning about the materials of ＂not to five as a unit,＂ ＂5 as a unit＂ and ＂character as a unit＂. Experiments 3 and 4 further investigated the subjects＇ cyclical temporal reasoning for different materials using the two-task paradigm. In the paradigm of two tasks, the primary task was cyclical temporal reasoning; the secondary task was odd-even number judging or picture judging. Experiments 1 and 2 showed that whether the materials is ＂not to five as a unit,＂ ＂5 as a unit＂ or ＂character as a unit,＂ the reaction time of Cantonese-Mandarin diglossiac speakers was longer than Mandarin speakers. Experiments 3 and 4 indicated that when the time materials were ＂5 as a unit＂, the reaction time of the Cantonese-Mandarin diglossic speakers and Mandarin speakers were affected strongly by the odd even number judging secondary task, and when the time materials were ＂＇ character＇ as a unit＂, the Cantonese-Mandarin diglossic speakers were affected strongly by the picture judging secondary task. This results implied that both Cantonese-Mandarin diglossic speakers and Mandarin speakers adopted number processing in time reasoning when the materials were ＂5 as a unit＂, but to the materials of ＂＇ eharacter＇ as a unit＂, Cantonese-Mandarin diglossic speakers
