本研究比较了数字的倾向，引起自发的知觉颜色或味道（联觉）的倾向，可视化的数字占据特定的视觉空间配置（数字形式）。数字形式的患病率被发现显着较高的联觉经验的颜色相比，联觉经验的味道和控制参与者缺乏任何联觉经验。这表明，通感颜色感觉的存在增强了以视觉空间格式明确表示数字的倾向，尽管这两种症状在逻辑上可能是独立的（即可能有没有颜色的数字形式，也可能有没有形式的彩色数字）。数字形式在男性和女性中同样常见，不像以前报道的通感。表明了强烈的女性偏见拥有数字形式的个体也可能拥有其他有序序列（例如天、月、字母）的视觉空间形式，这表明是数字的有序性质而不是数字量产生了这种特殊的表征模式。最后，我们还描述了数字形式对数字比较任务表现的一些影响。(c)2005 Elsevier B.V.保留所有权利。
This study compares the tendency for numerals to elicit spontaneous perceptions of colour or taste (synaesthesia) with the tendency to visualise numbers as occupying particular visuo-spatial configurations (number forms). The prevalence of number forms was found to be significantly higher in synaesthetes experiencing colour compared both to synaesthetes experiencing taste and to control participants lacking any synaesthetic experience. This suggests that the presence of synaesthetic colour sensations enhances the tendency to explicitly represent numbers in a visuo-spatial format although the two symptoms may nevertheless be logically independent (i.e. it is possible to have number forms without colour, and coloured numbers without forms). Number forms are equally common in men and women, unlike previous reports of synaesthesia. that have suggested a strong female bias. Individuals who possess a number form are also likely to possess visuo-spatial forms for other ordinal sequences (e.g. days, months, letters) which suggests that it is the ordinal nature of numbers rather than numerical quantity that gives rise to this particular mode of representation. Finally, we also describe some consequences of number forms for performance in a number comparison task. (c) 2005 Elsevier B.V. All rights reserved.
