Bidirectional Mapping Between the Symbolic Number System and the Approximate Number System.
Previous studies have discussed the symmetry of bidirectional mapping between approximate number system (ANS) and symbolic number system (SNS). However, these studies neglected the essential significance of bidirectional mapping in the development of numerical cognition. That is, with age, the connection strength between the ANS and SNS in ANS-SNS mapping could be higher than that in SNS-ANS mapping. Therefore, this study attempted to explore the symmetry of bidirectional mapping by examining whether the connection between the ANS and SNS is the same. Using two types of dot array materials (extensive and intensive) and sequence priming paradigms, this study found a stable negative priming effect in the ANS-SNS priming task, but no priming effect in the SNS-ANS priming task. In addition, although sensory cues (extensive and intensive) could affect performance in the ANS-SNS mapping task, these cues did not affect performance in the ANS-SNS priming task. In general, this study provides valuable insight into the symmetry of bidirectional mapping.
期刊介绍：
As its name implies, Experimental Psychology (ISSN 1618-3169) publishes innovative, original, high-quality experimental research in psychology — quickly! It aims to provide a particularly fast outlet for such research, relying heavily on electronic exchange of information which begins with the electronic submission of manuscripts, and continues throughout the entire review and production process. The scope of the journal is defined by the experimental method, and so papers based on experiments from all areas of psychology are published. In addition to research articles, Experimental Psychology includes occasional theoretical and review articles.
