Aksentijevic-Gibson complexity is an original complexity measure based on the amount of change in a string or 2D array that has been successfully implemented on data from psychology to physics. The key ingredient to computing the measure is a change symmetry (CS)-a novel form of structure (also known as generalised palindrome) which represents a central or mirror symmetry based on the redundant arrangement not of symbols but of changes. This results in patterns that although globally symmetrical do not appear as such when inspected locally. We used this property to (a) affect the registration of a target, (b) prime the symmetry judgment of 2D arrays and (c) faces using 1D patterns possessing change symmetry. In Experiment 2, we applied the lock and key principle to complete the prime without showing its structure at once. In Experiments 3 and 4, we presented subjects with fast sequences of CSs such that the configuration of an individual pattern was masked by the subsequent pattern leaving only the structural "essence" of the prime symmetry. The results strongly support the contention that higher-level hidden structure of change symmetry successfully primes the symmetry perception of 2D arrays as well as facial attractiveness.
阿克森提耶维奇-吉布森复杂度是一种基于字符串或二维数组变化量的原始复杂度度量方法，已成功应用于从心理学到物理学的数据。计算该度量的关键要素是变化对称性（CS）——一种新颖的结构形式（也称为广义回文），它基于冗余排列而不是符号，代表一种中央或镜像对称，这种排列基于变化。这导致了尽管全局对称但局部检查时并不明显的模式。我们利用这一特性来：(a) 影响目标的注册，(b) 为二维数组和 (c) 面孔的对称判断提供启动，使用具有变化对称性的一维模式。在实验 2 中，我们应用锁和钥匙原理来完成启动，而不立即显示其结构。在实验 3 和 4 中，我们向受试者呈现快速的 CS 序列，使得单个模式的配置被后续模式掩盖，只留下启动对称的结构“本质”。结果强烈支持这样一种观点，即变化对称性的更高层次隐藏结构成功地为二维数组的对称性感知以及面部吸引力提供了启动。
