| Abstract(in English) | In communicative situations, the referent of utterance is not always explicit. Therefore, our communication is sometimes ambiguous. For example, if someone says, "Look at 'that'!" we can identify "that" by looking for an event or object that is highly relevant to the cognitive environment we share with our communicative partner. This is one of the pragmatic processes of disambiguation, which shows that reference assignment is not necessarily about simply decoding the signals emitted by others. Because events that occur only rarely are more informative than events that occur frequently, and short-term memory is limited, events that occur close in time to an attention-catching event, such as an utterance, are more salient. Thus, we hypothesized that 'recency and rarity bias' would be at work when humans assign ambiguous utterances to referents. Immediately after the last event appeared, an initiator asked 'Did you see that?' and participants were asked to judge which event the initiator was referring to. The results showed that the percentage of participants who selected rare events steadily decreased as the rare event became more distant from the utterance. The results of the control condition ruled out the possibility that the majority of participants correctly selected the event that preceded the utterance and only selected the perceptually salient event. These results suggest that the compounding processes that humans use to determine the target of instructions in communicative settings show a bias towards salient events, especially those that are rare and temporally proximate, because they are more informative. |
