材料类型和颜色典型性影响颜色-物体Stroop效应

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。

The Effect of Material Type and Color Typicality on the Color-Object Stroop Effect

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 the color-object Stroop task can.The color-object relies on strength to attend to the color of an object to attract less attention to the surface features such as color.The theory on color-object has three points.The first is the exical interference account.Suppose that a child was asked to name colors and was 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.The second is the task sets competition.A visible object with a familiar form affords many possible tasks:i.e.,lexical decision,semantic classification,translation,free association,and color naming.The third is the executive control account.The color-object interference is the outcome of immature executive control in children.In the present study,we examined how the material type and color typicality influenced the color-object Stroop through two experiments.Experiment 1 studied the 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 the baseline.Each picture was in one of four colors.The subjects were asked to name the color.The results showed that the color typicality was significant.The color naming had significant color-object Stroop effect.Experiment 2 studied the color-object(word) Stroop effect.Twenty-nine college students were shown words of familiar objects in a color,which was typical of high,medium,low and the baseline.Each word was in one of four colors.The results showed that color typicality were significant whereas color naming was not.But color naming did exist.We found the different between color-objects(picture) Stroop and color-object(word) Stroop.The processing may be different between pictures and words.But the results of color typicality were the same.
