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。 相似文献

An adolescent female chimpanzee (Pan troglodytes) was trained to discriminate auditory compound stimuli differing in tonal frequency and/or tone on-off rate. Following acquisition
training and overtraining, she was shifted to multidimensional stimulus control testing using redundant relevant auditory
stimulus sets with discriminability of elements in each dimension varied systematically. Although the control by both dimensions
changed significantly as a function of discriminability, the degree of dimensional control was stronger in the tone on-off
rate than in the tonal frequency. These results clearly demonstrated “attentional” control of the chimpanzee's auditory discrimination
behavior and the interaction between two dimensions of auditory stimuli.
