Keyword:  视知觉无意识启动效应形状优势;
Abstract: 研究了视知证无意识加工中是否存在形状优势效应.被试为天津师范大学本科生60名.仪器为pentiun 11l高分辨率计锋机,程序用E-prime心理实验软件系统编制而成.在实验1中,用信号检测论技术发现,当启动图形呈现时间为20ms时,被试是不能觉知到该图形的.在实验2和3 中,被试的任务分别是判断图形的形状和颜色,用MANOVA分析启动图形对靶图形的启动效应时发现,启动图形的颜色线索不会影响靶图形的形状判断,但启动图形的形状线索却能抑制或促进靶图形的颜色判断.实验证据提示,在判断物体整体特征时,无意识知觉具有形状优势效应.
