| 目的：考查左右视野中不同位置字母的辨别力。方法：采用探测刺激的方法对左右视野中字母位置的识别差异进行了研究。
结果：通过SPSS15.0 进行重复测量方差分析得出：①不同视野的错误率主效应显著（F=5.98，P<0.05）；②探测位置的主效应非常
显著（F=15.39，P<0.01）；③不同视野与探测字母位置的交互作用非常显著（F=11.60，P<0.001）。结论：①位置错误多于字母错误，并
且位置错误中所报告的字母更靠近中央凹。②左视野中的首字母有较差的辨别力，而右视野中的尾字母有较差的辨别力。③左视
野中存在知觉系统的限制，而不是词汇识别策略中大脑左右半球的差异。④对词汇识别中大脑左半球平行加工、右半球系列加工
的说法提出了质疑。 |

| Objective: We assessed the discriminability of various letter positions in the left (LVF) and right (RVF) fields of vision.
Methods: We used a bar-probe task to study the discriminability of letter position in the left and right fields of vision. Results: We used
SPSS15.0 repeated measure to analyze, and get the results that ①the main effect of different fields of vision is significant（F=5.98，P<0.
05）; ②The main effect of different letter positions is very significant （F=15.39，P<0.01）; ③The interaction between different fields of
vision and different letter positions is very significant （F=11.60，P<0.001）. Conclusions: ① The results indicated location errors vastly
outnumber item errors, and the misreported letter was more close to the foveal. ②The obtained error functions highlighted the poor
discriminability of initial letters in the LVF and latter letters in the RVF. ③ There is a restriction of sensory system in the Left field of
vision, not the differences between left and right hemisphere when recognize words. ④ We casted doubt on parallel models in the left
hemisphere and sequential models in the right hemisphere of word processing. |
