用Ｓ－Ｒ相容性来操纵心理潜伏期的反应选择过程，用反应的复杂性来操纵心理潜伏期的反应组织过程。发现Ｓ—Ｒ相容性影响反应选择过程；反应的复杂性影响反应组织过程；Ｓ—Ｒ相容性对反应时的效应与反应的复杂性对反应时的效应有交互作用。提出心理潜伏期的心工模型，很好地解释了Ｓ—Ｒ相容性对反应时的主效应，反应复杂性对反应时的主效应，以及Ｓ—Ｒ相容性与反应的复杂性对反应时的效应的超加法交互作用的等实验现象。 The reaction selection process that manipulates the psychological latency with S-R compatibility manipulates the reactive tissue processes of the psychological latency with the complexity of the reaction. It is found that the S-R compatibility affects the reaction selection process; the complexity of the reaction affects the process of the reaction; the effect of the S-R compatibility on the reaction and the complexity of the reaction have an interaction on the reaction-time effect. The mental model of psychological latency was proposed to explain well the main effect of S-R compatibility on reaction, the main effect of reaction complexity on reaction, and the compatibility of S-R and the complexity of response to reaction When the effect of super-additive interaction and other experimental phenomena.
