Upon hearing a scalar adjective in a definite referring expression such as “the big…,” listeners typically make anticipatory eye movements to an item in a contrast set, such as a big glass in the context of a smaller glass. Recent studies have suggested that this rapid, contrastive interpretation of scalar adjectives is malleable and calibrated to the speaker's pragmatic competence. In a series of eye‐tracking experiments, we explore the nature of the evidence necessary for the modulation of pragmatic inferences in language comprehension, focusing on the complementary roles of top–down information ‐ (knowledge about the particular speaker's pragmatic competence) and bottom‐up cues (distributional information about the use of scalar adjectives in the environment). We find that bottom‐up evidence alone (e.g., the speaker says “the big dog” in a context with one dog), in large quantities, can be sufficient to trigger modulation of the listener's contrastive inferences, with or without top‐down cues to support this adaptation. Further, these findings suggest that listeners track and flexibly combine multiple sources of information in service of efficient pragmatic communication. 相似文献

This study evaluated a distraction intervention designed to reduce the distress of preschool children undergoing repeated chemotherapy injections. Twenty-nine children aged 2-5 years were randomly assigned either to distraction by a developmentally appropriate electronic toy or to a wait-list control. Children who received the distraction intervention demonstrated lower overt behavioral distress and were rated by parents and nurses as less anxious than children in the control condition. The improvements were maintained over the 8-week intervention. The results suggest that a developmentally appropriate, multisensory, variable-distracting activity that requires active cognitive processing and active motor responses may be a viable cost-effective alternative to more time-intensive parent-training programs for preschool-age children. 相似文献
