初中数学优差生注意转换中的线索和准备效应

Effects of Cue and Preparation in Shifting Attention of High-and Low-proficiency Junior High School Learners of Math

选取34名初中数学优差生为被试,采用任务转换实验考察其注意转换中的线索效应和准备效应。结果表明:一般转换代价出现了线索效应和准备效应,特定转换代价仅出现了线索效应,优生比差生更善于利用线索和准备间距提高任务转换成绩。

The paradigm of task switching was used to examine the effects of subjects were 34 high- and low-proficiency junior high school learners of cue and preparation in shifting attention. The math. The results indicated that there were significant effects of cue and preparation for general switch cost ; and there were only significant effects of cue for special switch cost. High-proficiency learners could make better preparations for the incoming trail through cue and preparation interval than low-proficiency learners.
