大人が語の意味の推測を行う際の他者の動作・形状バイアス・命名の作用

抄録

The present study examined whether adults' inferences about word meanings are influenced by others' actions upon objects, shape bias, and labeling the objects. In Experiment 1, an experimenter presented 24 Japanese adults a nonsense label with standard solid object that was either rigid (e.g., steel) or flexible (e.g., sponge). The experimenter performed an action on the object that emphasized the shape (e.g., rolling) or the material (e.g., squeezing) of these standards. The experimenter then asked these adults to choose a novel object likely to share the label with the standard from one with the same shape and one with the same material. In Experiment 2, the experimenter asked 32 Japanese adults to choose an object with and without nonsense labels. The results showed that the adults used action information to make their choices regardless of the presence of labels. When labels were provided, the adults attended action information in a greater degree than when no labels were provided.
