时间选择性注意的左半球优势效应：来自注意瞬脱研究范式的证据

THE LEFT HEMISPHERE ADVANTAGE FOR SELECTIVE TEMPORAL ATTENTION：EVIDENCE FROM AN ATTENTION BLINK PARADIGM

采用注意瞬脱范式探讨时间注意加工上的大脑单侧优势效应的争论。实验选用字母和几何图像两种材料，要求被试报告 T1和 T2呈现的字母或几何图像是否相同。结果发现：无论是字母检测，还是几何图形检测，T2右视野呈现时变化检测正确率都高于左视野。上述结果表明，时间加工任务上存在左半球优势效应，支持时间加工的特异性假设。

The modified Attention Blink Paradigm was used to investigated lateralization for temporal processing.In digit and geometry discrimination tasks,the subjects were required to detect the difference between T1 and T2 stimulus.In both tasks,the performance of the right visual field was higher than left visual field.The results suggest the left hemisphere plays more important role for temporal processing,and support the hypothesis of a functional and heterogeneous left hemisphere advantage for temporal resolution.
