Manumerical cognition: Assessing the contributions of ordinal, cardinal and spatial components of finger counting to adult numerical cognition

受知识表征具体化方法的启发，该项目首次测量了手指计数的序数、基数和空间方面对成人数字认知的详细贡献。计数时的手指姿势既具有顺序/序数属性，又具有静态/基数属性，其在视觉和听觉通道中对数字加工的贡献将通过两个方面的研究来考察。被动手指刺激(6个实验)评估当时间或空间分布的触觉刺激与计数模式一致时，数字识别是否受益于时间或空间分布的触觉刺激。我们还直接测量了计数姿势的活跃生产(9个实验)，并确定了它对大小和奇偶性加工的影响。这些预期的结果为当前关于知识表示的理论观点、数字知识的多模式模型和教学实践提供了参考。

Inspired by an embodied approach to knowledge representation, this project measures, for the first time, detailed contributions of ordinal, cardinal, and spatial aspects of finger counting to adult numerical cognition. Finger postures in counting have both sequential/ordinal and static/cardinal attributes, and their contributions to number processing in the visual and auditory modalities will be examined with two lines of research. Passive finger stimulation (6 experiments) evaluates whether numerosity discrimination benefits from temporally or spatially distributed tactile stimulation when it is congruent with counting patterns. Active production of counting postures (9 experiments) is also directly measured, and its effects on magnitude and parity processing determined. The expected results inform current theoretical views of knowledge representation, multimodal models of number knowledge, and pedagogical practice.
