【摘要】：目的:通过展开听力障碍儿童到成人的视觉注意发展研究,考察听力障碍是否会引起注意机制的改变。方法:采用瑞文标准推理测验排除智力障碍,将受试分成两组:听力障碍组(10～12岁儿童11名、14～16岁青少年15名、成人15名)和听力正常组(10～12岁儿童12名、14～16岁青少年16名、成人15名),采用DMDX系统呈现实验材料,并记录受试完成视觉注意任务的反应时和准确率。结果:10～12岁儿童受试的反应时长于14～16岁青少年受试和成人受试[(925.2±277.2)vs(784.7±240.4),(764.2±197.2);均P0.05];组内变量线索的有效性主效应显著,被试对有效线索提示的反应快于无效线索的反应[(762.8±164.0)vs(849.1±238.6),P0.001]。结论:听力障碍改变了个体的视觉注意技能,但是听力障碍受试和听力正常受试在内源性和外源性注意方面表现一样,听力障碍并没有影响到个体的注意机制的发展。
[Abstract]:Aim: to investigate whether hearing impairment may lead to the change of attention mechanism through the study of visual attention development from children with hearing impairment to adults. Methods: using the Raven standard reasoning test to eliminate mental retardation, the subjects were divided into two groups: hearing impairment group (11 children aged 10 to 12 years, 15 adolescents aged 14 to 16 years, and 15 adults) and normal hearing group (12 children aged 10 to 12 years). DMDX system was used to present the experimental materials and record the reaction time and accuracy of the subjects to complete the visual attention task. Results: the reaction time of children aged 10 to 12 was longer than that of adolescents and adults (925.2 卤277.2) vs (784.7 卤240.4), (764.2 卤197.2); The main effect of cues in group was significant, and the response to effective cues was faster than that of ineffective cues [(762.8 卤164.0) vs (849.1 卤238.6), P0.001]. Conclusion: hearing impairment changes the individual's visual attention skills, but the hearing impairment subjects and the hearing normal subjects have the same performance in endogenous and exogenous attention, and hearing impairment does not affect the development of individual attention mechanism.
