对多位数字加工的研究表明，在阿拉伯数字中，无论何时使用与数量相关的任务，它们的位置值数量都会自动激活。然而，到目前为止，它是未知的，是否也被激活时，目标任务是大小无关的位置值。目前的研究使用两位数的奇偶全等效应来检验这个问题：它描述了对十位数奇偶全等数（例如，35，46;十年和单位的奇偶性相同）比十位奇偶性不全等数（例如，25; 36;十年和单位的不同奇偶性）。在这里，我们调查的奇偶一致性效应的（a-）对称性，即是否有差异，无论是参与者正在评估单位数字或十年数字的奇偶性。我们详细说明，如何以及为什么这样的不对称性与位值处理，因为奇偶性的单位数字只干扰奇偶性的十年数字，而奇偶性的十年数字干扰奇偶性的单位数字和综合奇偶性的整个两位数。我们观察到一个显着更大的奇偶一致性效应，在十年奇偶决定比单位奇偶决定。这表明，自动位置值处理也发生在一个典型的奇偶性判断任务，其中大小是无关紧要的。最后，由于研究的跨语言设计，我们可以证明这些结果及其影响是语言无关的。
Research on multi-digit number processing suggests that, in Arabic numerals, their place-value magnitude is automatically activated, whenever a magnitude-relevant task was employed. However, so far, it is unknown, whether place-value is also activated when the target task is magnitude-irrelevant. The current study examines this question using the parity congruency effect in two-digit numbers: It describes that responding to decade-digit parity congruent numbers (e.g., 35, 46; same parity of decades and units) is faster than to decade-digit parity incongruent numbers (e.g., 25; 36; different parities of decades and units). Here we investigate the (a-) symmetry of the parity congruency effect; i.e. whether it makes a difference whether participants are assessing the parity of the unit digit or the decade digit. We elaborate, how and why such an asymmetry is related to place-value processing, because the parity of the unit digit only interferes with the parity of the decade digit, while the parity of the decade digit interferes with both the parity of the unit digit and the integrated parity of the whole two-digit number. We observed a significantly larger parity congruency effect in the decade parity decision than in the unit parity decision. This suggests that automatic place-value processing also takes place in a typical parity judgment task, in which magnitude is irrelevant. Finally, because of the cross-lingual design of the study, we can show that these results and their implications were language-independent.
