中文摘要:
      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。
英文摘要:
      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.
