Text Complexity.

Legend: The level of complexity of both types of written content (psychographed: P and control task: CT) was analyzed for each volunteer separately (Experienced: Exp and Less expert: Lex). Average complexity scores for psychographed content were higher than those for control-task writing, for both the whole sample [16.8 (SD 3.33) vs 14.4 (SD 2.95) - p = 0.007] and for experienced mediums [18.4 (SD 2.30) vs 15.4 (SD 3.36) - p = 0.041]. For less expert mediums, the difference was near significance [15.2 (SD 3.63) vs 13.4 (SD 2.41) - p = 0.066]. Planning for psychography writing was, on average, more sophisticated than for the control task, and the higher level of complexity relating to the more extensive planning work during psychography would require more activity from areas involved in cognitive processing.说明：本研究针对两类书写内容：灵写内容（psychographed，简称P）与对照任务书写（control task，简称CT）的复杂度水平，分别针对每名被试进行分析，被试分为资深通灵者（Experienced，简称Exp）与非资深通灵者（Less expert，简称Lex）两个亚组。 在全体被试样本[16.8（标准差（standard deviation，SD）3.33）vs 14.4（标准差（standard deviation，SD）2.95），p=0.007]与资深通灵者亚组[18.4（标准差SD 2.30）vs 15.4（标准差SD 3.36），p=0.041]中，灵写内容的平均复杂度得分均显著高于对照任务书写内容。 非资深通灵者亚组的组间差异则接近统计学显著性水平[15.2（标准差SD 3.63）vs 13.4（标准差SD 2.41），p=0.066]。 平均而言，灵写任务的前期规划复杂度亦高于对照任务；灵写过程中更繁复的规划工作所对应的更高复杂度水平，需要认知加工相关脑区投入更多活动。
