【摘要】：目的探讨3～5年级小学生对不同频率纯音、调制音的时长间隔感知处理能力及其与学业成绩之间的相关性。方法采用3×4×2混合实验设计,对105名3～5年级小学生分别用不同声音类型(纯音、调频音、调幅音)和不同频率(500、1 000、2 000、4 000Hz)的声音组合进行时长感知测试,比较其最小差别感知阈值。结果①3～5年级小学女生对500Hz纯音的时长感知能力较4 000Hz强(P=0.008),对500Hz调幅音的时长感知能力较500Hz调频音更强(P=0.025);3～5年级小学男生对500Hz调幅音的时长感知能力较1 000Hz差(P=0.025),而女生对500Hz调幅音时长感知能力较男生强(P=0.027);②3～5年级小学生的学业成绩与时长感知能力呈负相关(r=-0.425,P0.05)。结论时长感知能力作为听觉中枢处理的最基本能力之一,可能直接影响3～5年级小学生个体学习能力的发展。
[Abstract]:Objective to explore the relationship between the processing ability of time interval perception and academic achievement of pupils in grade 3 and 5 in different frequency pure tone and modulation tone. Methods using a 3 脳 4 脳 2 mixed experimental design, 105 pupils in grade 5 were tested with different sound types (pure sound, frequency modulation, amplitude modulation) and different frequencies (5001000 / 2 000 / 4 000Hz). The minimum difference perception threshold is compared. Results the duration perception of 500Hz pure tone was stronger than that of 4 000Hz (P0. 008), and that of 500Hz AM was stronger than that of 500Hz FM (P0. 025). 3The duration perception of 500Hz amplitude modulation in primary school boys in grade 5 was worse than that in 1 000Hz (P0. 025), while the duration perception of 500Hz in girls was stronger than that in males (P0. 027). There was a negative correlation between the academic achievement and the time perception ability of the pupils in grade 5 (r = -0.425, P 0.05). Conclusion as one of the most basic abilities of auditory central processing, the ability of time perception may directly affect the development of individual learning ability of grade 3 pupils.
