项目摘要

Linguistic influences on numerical cognition have been neglected for years and it has been argued that central semantic number processing occurs largely without linguistic influences. However, the last years have seen a surge of studies showing that different linguistic aspects exert major influence on virtually all domains of numerical processing. Here we will focus on the grammatical attributes of number words, which have never been studied before beyond infant age. The project is the first to make use of the natural specificities of the Polish and German (and in some control studies English) languages in such a trans-lingual approach. In contrast to the transparent rules in German (1 singular, all other numbers plural), grammatical attributes of number words in Polish are much more complex. For instance, verb form changes with number: singular for 1, plural from 2-4, singular again from 5-9; singular for 21, 31 etc., plural for 22-24, 32-34 etc., singular for 25-29, 35-39 etc. Based on early grammatical effects in infant literature and because other linguistic influences persist into adulthood, we hypothesize that above irregularities also influence numerical cognition. The first research line will systematically examine this hypothesis for single-digit numbers in preschool children, elementary school children, and adults. The second research line will focus on grammatical influence on multi-digit numbers, for which German has a particular irregularity as regards the lexical composition of number words: The order of its constituent elements is inverted (one-and-twenty). Therefore, all grammatical aspects influencing multi-digit number processing will be examined in Polish, English and German to dissociate grammatical from lexical linguistic influences. Throughout the whole project, all trans-lingual studies will be conducted exactly parallelized in the different countries. Besides behavioral data (RT and errors), we included advanced methods like fNIRS and eye-tracking for the first time in a such a trans-lingual setting in numerical cognition to better explore underlying (neuro-)cognitive processes driving linguistic differences. We believe that such basic research will considerably improve our understanding of the impetuses of numerical development and cognition.

语言对数字认知的影响多年来一直被忽视，有人认为，中央语义数字处理发生在很大程度上没有语言的影响。然而，过去几年来，大量的研究表明，不同的语言方面施加重大影响，几乎所有领域的数字处理。在这里，我们将集中在语法属性的数字的话，这从来没有被研究之前超过婴儿的年龄。该项目是第一个以这种跨语言方法利用波兰语和德语（在一些对照研究中还有英语）的自然特性的项目。与德语中的透明规则（1个单数，所有其他数字都是复数）相比，波兰语中数字词的语法属性要复杂得多。例如，动词形式随着数字的变化而变化：单数表示1，复数表示2-4，单数表示5-9;单数表示21，31等，复数表示22-24、32-34等，单数为25-29，35-39等。基于早期语法的影响，在婴儿文学，因为其他语言的影响持续到成年，我们假设，上述不规则性也影响数字认知。第一条研究线将系统地检验学龄前儿童、小学儿童和成人的个位数假设。第二条研究路线将集中在语法上的影响，多位数，其中德国有一个特殊的不规则性方面的词汇组成的数字：其组成元素的顺序是颠倒的（一和二十）。因此，所有的语法方面影响多位数处理将在波兰语，英语和德语中进行检查，从词汇语言的影响分离语法。在整个项目中，所有跨语言研究将在不同国家完全平行进行。除了行为数据（RT和错误），我们还首次在数字认知的跨语言环境中纳入了fNIRS和眼动追踪等先进方法，以更好地探索驱动语言差异的潜在（神经）认知过程。我们相信，这样的基础研究将大大提高我们对数字发展和认知动力的理解。
