空间转换在记叙文阅读情境模型建构中的作用

The Role of Spatial Shift in Constructing Situation Model of the Narrative Reading

采用探测词和事件分割范式探讨了空间转换与事件转换分离的情况下,空间转换在记叙文情境模型建构中的作用。实验1a重复前人研究,探讨空间转换对阅读时间和情境模型更新的影响,并验证在空间转换对情境模型的影响的研究中,采用多指标探测范式的合理性。实验1b探讨在空间转换与事件转换相分离的条件下,空间转换对情境模型更新的影响;实验2a探讨空间转换对事件分割的影响,并验证在空间转换对情境模型的影响的研究中,采用事件分割范式的合理性;实验2b探讨空间转换与事件转换相分离的条件下,空间转换对事件分割的影响,从而验证空间转换对情境模型更新的影响。结果表明,当空间转换与事件转换相分离时,不引起情境模型的更新,事件单元是建构记叙文心理表征的核心单元,空间转换只有在标识事件转换的情况下,才能引发读者更新情境模型。

Situational model is one of the most intensively investigated topics on discourse comprehension. Up to date, it is widely agreed that narrative comprehension includes mental representation that is based on text description. Event-indexing model explains situational model in detail. The former model proposes that events are the core units of the mental representation, which are defined in five situational dimensions： time, space, character, causality and intentionality. Space is an important dimension for constructing situational model, and a number of studies have shown that readers track spatial information while reading texts. In addition, some studies provided evidence supporting that readers use spatial shift to segment the consecutive narrative. Radvansky and Copeland （2010） explored the influence of spatial shift on the processes of situational model updated in narrative reading by multi-index detection paradigm, which integrated the previous study on spatial situational model updating. However, after scrutinizing their experiment, we found that they did not separate the factors spatial shift and event shift, which actually are not consistent. Based on the above consideration, event segmentation and probe words paradigms were adopted to investigate the function of event shift and spatial shift in narrative reading by four experiments. Experiment 1a repeated a previous study, exploring the effect of spatial shift on situational model updating and reading time, and further verified the rationality of using multi-index detection paradigm in our study. Experiment 1b investigated the influence of spatial shift on situational model updating under the separation of spatial shift and event shift. Experiment 2a studied the effect of spatial shift on event segmentation, and further verified the rationality of using event segmentation paradigm in our study. Experiment 2b explored the influence of spatial shift on event segmentation under the separation of spatial shift and event shift, which can verify the affect of spatial shift to situational model updating. The results showed that the separation of spatial shift and event shift did not cause the updating of situational model. Event unit was the core unit of constructing the narrative’s mental representation. Only when the event shift was identified could spatial shift cause readers to update situational model.
