基于“上声的本质是低平调”的观点,通过合成真词和非真词刺激音的平调连续统,采用选择辨认和区分实验的方法,分别对两组汉语被试、一组韩语被试进行高平调(阴平)和低平调(上声)的听感分界的考察。结果发现:母语经验和刺激类型在辨认和区分实验中互相作用,但作用大小各不相同。辨认边界、边界宽度、辨认反应时间受母语经验的影响显著;而区分峰值、峰界对应、区分反应时间则受刺激类型的影响显著。另外,通过三组被试实验的对比,还证明了上声感知空间的动态性特点。 Based on the viewpoint that “the nature of the sound on the lower is flat tone ”, through the method of selecting and distinguishing experiments by synthesizing the flat-tone continuum of real words and non-real-word stimuli tones, In the group of Korean subjects, the auditory demarcation of Gao Ping Diao (Yin Ping) and low flat tone (Shang Sheng) was investigated. The results showed that mother tongue experience and stimulus types interact with each other in distinguishing and distinguishing experiments, but the effects vary in size. Identifying the boundaries, the width of the border, and the recognition reaction time are significantly affected by the mother tongue experience. However, the distinction peak, the peak boundary correspond, and the distinction reaction time is significantly affected by the type of stimulation. In addition, through the comparison of the three groups of experimental subjects, it also proves the dynamic characteristics of the upper acoustic perception space.
