But in the condition when the first project is characters and the end project is pictures , the reaction time is faster when the end project is also characters , along with that the transformation speed of imagery presentation is faster than that of proposition presentation, the reason may be that imagery presentation can stimulate proposition presentation automatically, the transformation is self-moving processing and independent from will, but it is not self-motive but controlled processing and will needs when the proposition presentation transforms into imagery presentation.

但在首项目是字的时候，尾项目是图的条件下被试反应时快于尾项目是字的条件下，又表明图像表征比命题表征的转换速度快，原因可能是由于图像表征能够自动激活命题表征，其转化是自动加工的、几乎不信赖于意志努力的，而命题表征转化为图像表征却不是自动的，而是控制加工的、需要意志努力的过程。
