We examined the differences between estimating the emotions of protagonists and evaluating those of readers in narrative comprehension. Half of the participants read stories and rated the emotional states of the protagonists, while the other half of the participants rated their own emotional states while reading the stories. The results showed that reading comprehension was facilitated when highly extraverted participants read stories about, and rated the emotional experiences of, extraverted protagonists, with personalities similar to their own. However, the same facilitative effect was not observed for less extraverted participants, nor was it observed for either type of participants under the condition in which participants rated their own emotional experiences. Thus, at least for highly extraverted participants, readers both facilitated the construction of a situation model and correctly estimated the emotional states of protagonists who were similar to themselves, perhaps due to empathy.

One of the major characteristics of autism is impairment of communication and socialization. While such impairment per se has been well documented, research into effective interventions for children with this developmental disorder is still limited. Here we present preliminary evidence for the possibility of improvement of the capability of social perspective-taking in schoolchildren with autism by having intensive experience with narrative, in which they were exposed to narrative in story books read by their parents over a consecutive 5- to 6-day-period. When their capability was evaluated on the basis of a conventional role-taking task, the mean score tended to increase after the exposure as compared to before the exposure, whereas such a change was not recorded in children who did not experience such exposure. These effects were confirmed when the children were retested 4 months later. Although preliminary, the current study represents a step toward the development of more effective social perspective-taking interventions for children with autism.

We investigated output-monitoring errors in a modified source-monitoring paradigm. Unlike the traditional paradigm that involves two phases, learning and monitoring, the modified paradigm involves three phases, learning, enactment, and monitoring. Three experiments produced two major findings. First, compared with the traditional paradigm, the modified paradigm produced fewer monitoring errors. Second, performing a dual-task during the enactment phase increased monitoring errors for the items that participants repeatedly enacted during the learning phase. In contrast, performing a dual-task during the learning phase did not influence monitoring errors. It only decreased the number of items that were enacted during the enactment phase. We concluded that monitoring errors are more likely to occur (a) when the modality of items matches between the learning and enactment phases (i.e., items are enacted during both phases), and (b) when a dual-task increases processing demands during the enactment phase.

This study focused on the relationship between personal perceptual memory and story comprehension. In two experiments, participants read story texts. Half the participants were asked to retrieve highly vivid perceptual memories (Exp. 1) or autobiographical memories as highly perceptual and personal memories (Exp. 2) before reading a story, and the other half were asked to retrieve less vivid perceptual memories, as a control task, before reading. Results showed that participants read more slowly under the highly perceptual memory retrieval condition only when their experiences were relatively similar to the experiences depicted in the story. Additionally, similarity between story content and participants' experiences was positively correlated with enjoyment of the story in both experiments. We interpreted the results as indicating that individuals are involved in emotional processes when they are able to integrate their own perceptual memories into the story content. Personal perceptual memory also appeared to contribute to story comprehension.
