本研究采用刺激探测任务,探讨负数的低水平加工能否引起空间注意的转移。实验一仅用负数作为线索,结果表明:对负数绝对值大小的加工能引起空间注意的转移。实验二用正数、负数和零混合作为线索,结果表明:对负数数量大小的加工能引起空间注意的转移。本研究表明,对负数的低水平加工可以引起空间注意的转移,但是其绝对值还是数量大小的加工引起注意转移依赖于共同参与的其它数字加工产生的影响。
By using the stimuli detection task, the present study was to investigate, whether low level processing of negative numbers could cause spatial shifts of attention, and whether it depended upon their magnitude or absolute value. The results of Experiment 1, in which only negative numbers were included, revealed spatial shifts of attention depending upon the absolute value of negative numbers, whereas the results of Experiment 2, in which positive, negative numbers and zero were mixed, revealed spatial shifts of attention depending upon their magnitude. As a whole, the study suggested that low level processing of negative numbers could cause spatial shifts of attention. However how it does, seemed to depend upon the inter- influence of other involved numbers.
