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。

关 键 词:基础心理学  认知语言学  探测方法  左右视野  辨别力

Abstract: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.
Keywords:Basic Psychology  Cognitive Linguistics  Bar-probe task  The left and right fields of vision  Discriminability
