Unpaired, two-tailed t-tests of subject-condition PC expression coefficients.

Of the 34 PCs admitted to analysis by the Kaiser-Guttman criteria, only PC 1, 3, 26 and 32 showed significant differences (p<0.05 corrected for multiple comparisons according to the Bonferroni t procedure, in bold) in any of the nine indicated t-tests comparing subject-condition expression coefficients corresponding to the phases of the paradigm. P1 and P2, explorations of first and second parallelepipeds; R1, interval between explorations; R2, recovery between presentations of pairs; Ss, exploration of the spheres; a, above and b, below the discrimination threshold.

依据凯泽-古特曼准则（Kaiser-Guttman criteria）纳入分析的34个主成分（Principal Components, PC）中，仅PC 1、PC 3、PC 26与PC 32在9项针对实验范式各阶段对应被试-条件表达系数的t检验中呈现显著差异（经邦费罗尼t检验法（Bonferroni t procedure）校正多重比较后p<0.05，结果以粗体标注）。其中：P1与P2分别对应首个及第二个平行六面体的探索任务；R1代表两次探索之间的间隔时长；R2代表成对刺激再次呈现前的恢复时长；Ss代表对球体的探索任务；a代表高于辨别阈值，b代表低于辨别阈值。
