There were no significant facilitating effects to the retention of signaled information in the overuse of text signals condition, but there were in the selective use of text signals condition. Experiment 3, in which 2 small experiments contained, studied the effects of reader-based factors. Experiment 3a examined the effects of the familarity to the text topics and the readers' reading levels. Experiment 3b explored the effects of cognitive style and the intention to use the text signals. The results were as the follows: There were no significant difference between the signaled and unsignaled conditions in the circumstance of high familarity to the text topics, but there were significant differences between them in the circumstances of lower familarity to the text topics. There were no significant differences between the signaled and unsignaled conditions for the field-independent participants, but there were for the field-dependent participants. All the participants with different reading levels were helped by the text signals.

实验3 对不同主体因素条件下文章标记效应进行了研究，分2个分实验，实验3a以高中二年级学生为被试，研究了文章主题熟悉程度与阅读水平对文章标记效应的影响，实验3b以初中二年级学生为被试，探索了读者不同的认知方式与标记利用的意向对文章标记效应的影响，实验3结果发现，读者的阅读水平、对文章主题的熟悉程度、认知方式和利用标记意向等因素影响着文章标记效应，在文章主题熟悉的条件下，有无文章标记无显著差异，但在主题不熟悉条件下，有文章标记的效果显著优于无标记的效果；对场独立被试而言，有无标记无显著差异，但对场依存被试来说，有标记条件显著优于无标记条件；文章标记对不同阅读水平被试都有显著促进效应；文章标记利用意向对场独立与场依存被试都有显著促进效应。

In addition, deterministic calculations were carried out using (1) arithmetic mean values of untransformed hydraulic parameters,(2) arithmetic mean values obtained after backtransformation of Gaussian distributed parameters, and (3)alternatively using a set of mean bimodal retention and conductivity curves. Predictions obtained with the two stochastic methods and the deterministic cases are compared with measured cumulative outflow and moisture content profiles from fifteen 1 m long undisturbed soil columns collected along the same transect.
