Infant Perception of Numerosity

摘要: A multiple habituation paradigm was used to determine whether 10--12-month-old infants were able discriminate between visual arrays which differed only in their numerosity (2 vs. 3, 4, or 4 5 items). 96 tested one of two conditions. In the heterogeneous condition, habituated a series slides number items remained invariant, while item type (e.g., dogs, houses, etc.), size, and position varied on each slide. homogeneous both (chicks) size stimuli varied. Infants conditions then with contained either N + 1 - items. The results demonstrated that, regardless condition (homogeneous/heterogeneous), 2 3 unable For versus discrimination, x sex interaction indicated that females discriminated males make discrimination condition. Since subjects this study preverbal infants, suggest early counting skills are preceded by more perceptual awareness numerosity.
