乳幼児における数量のクロスモダルマッチング(第23回大会 優秀発表賞抄録)

抄録

This study investigated whether infants and young children are able to perform crossmodal matching of small numerosities, i.e., the recognition of numerical equivalence between sets presented with different sensory modalities. In an infant experiment that used a violation-of-expectation paradigm, 6-month-old infants looked significantly longer at the numerically non-equivalent events (e.g., 2-tone/3-object events) than at the numerically equivalent events (e.g., 3-tone/3-object events). In a child experiment that used a matching-to-sample task, 3- to 4-year-old children were able to select correctly the stimulus card that matched the number of tones they heard (0-4 tones). These findings suggest that infants and children are capable of relating small numerosities of sets presented with different sensory modalities.
