Abstract: The color–object Stroop is one of the paradigm of the color–word Stroop .The color–word task cannot be administered to those who are unable to read，but color–object Stroop task can. The color-object relies on the strong to attend to the color of an object to pay less attention to surface features such as color. The Theory on color-object has three Points. Firstly, Lexical interference account. Suppose that a child is asked to name colors and is then shown a picture of red scissors. The picture may activate both the word scissors and the word red, and the activation of scissors may interfere with the production of red. Secondly, Task sets competition. as a visible object with a familiar form affords many possible tasks: naming, lexical decision, semantic classification, translation, free association, and color naming, et al. Thirdly, executive control account. The color–object interference is the outcome of immature executive control in children. In present study, we study the material type and color typicality influence the color-object Stroop through 2 experiments. In experiment 1, to study color - object (picture) Stroop effect. Thirty-three college students were shown pictures of familiar objects in a color that was typical of high, medium, low and baseline. Each picture in one of four colors. Subjects were asked to name the name and color. The results showed that the color typicality were significant. The naming names and the color have significant color – object Stroop effect. In experiment 2, to study color - object(word) Stroop effect. Twenty nine college students were shown word of familiar objects in a color that was typical of high, medium, low and baseline. each word in one of four colors. The results showed that the color typicality were significant. Naming names didn’t exist with color- object Stroop effect, but color naming did exist. We founded the different about color - objects(picture) Stroop and color - object (word) Stroop. It may be the processing is different to pictures and words .But the results of color typicality are the same.

Key words: Stroop effect, Color-object Stroop effect, Material type, Color typicality

摘要： 通过两个实验考查材料类型和颜色典型性对颜色-物体Stroop效应的影响。实验1，考查颜色-物体（图片）Stroop效应。结果颜色典型性差异显著,命名图片的颜色和图片的名称都产生显著的颜色-物体Stroop效应。实验2，考查颜色-物体（词语）Stroop效应。结果颜色典型性差异显著，命名词语的颜色产生颜色-物体Stroop效应，命名词语的名称未产生颜色-物体Stroop效应。结论，材料类型和颜色典型性影响颜色-物体Stroop效应。
