数字认知文献中的一个新生概念-类比假设（Pinel，Piazza，Bihan，& Dehaene，2004）-假设符号的表示有一个共同的噪音代码（例如，数字）和非符号（例如，数量、物理尺寸、亮度）大小。目前的工作从一般识别理论（GRT;阿什比和汤森，1986）的角度对这一假设进行了各种测试-信号检测理论（绿色和瑞典人，1966）的多维扩展。GRT被应用于数值大小和物理大小的维度，其目标如下：（a）表征这些维度在心理空间中的内部表征，以及（B）评估支配这些维度感知的各种类型的（不）依赖性和可分性。结果表明，各种违反的独立性和可分性与Stroop不一致，但没有与Stroop一致的刺激。结果表明，Stroop一致性和不一致性刺激之间的结构有很深的差异，远远超出了所涉及的语义关系。
A nascent idea in the numerical cognition literature - the analogical hypothesis (Pinel, Piazza, Bihan, & Dehaene, 2004) - assumes a common noisy code for the representation of symbolic (e.g., numerals) and nonsymbolic (e.g., numerosity, physical size, luminance) magnitudes. The present work subjected this assumption to various tests from the perspective of General Recognition Theory (GRT; Ashby & Townsend, 1986) - a multidimensional extension of Signal Detection Theory (Green & Swets, 1966). The GRT was applied to the dimensions of numerical magnitude and physical size with the following goals: (a) characterizing the internal representation of these dimensions in the psychological space, and (b) assessing various types of (in) dependence and separability governing the perception of these dimensions. The results revealed various violations of independence and separability with Stroop incongruent, but not with Stroop congruent stimuli. The outcome suggests that there are deep differences in architecture between Stroop congruent and incongruent stimuli that reach well beyond the semantic relationship involved.
