概括

患有眼 (眼) 的儿童表现出眼手协调和运动计划受损. 这种视觉状况影响精确的抓取和对象操纵,而不是达到运动.

科学领域:

神经科学是一个神经科学.
发展心理学发展心理学
眼科医生眼科眼科

背景情况:

眼手协调对于日常视觉运动控制至关重要.
眼,或惰的眼睛,与视觉运动的缺陷,如缓慢的运动和抓住错误在儿童.

研究的目的:

调查眼对眼睛和手部运动时间协调的影响.
在患有眼症的儿童中,在达到,抓取和放置任务时表征视觉运动控制缺陷.

主要方法:

招募了28名患有野视的儿童和56名典型发育的同龄人 (6-14岁).
使用一个珠子线程任务,同时记录眼睛和手的动作.
分析了运动启动,固定时间和眼睛-手的延迟.

主要成果:

患有野外视障碍的儿童的整体表现较差,对物体操纵的缺陷比触及更大.
双眼儿童的运动反应时间较短,但抓取和放置的固定时间较长.
减少眼手延迟差异表明,在双眼儿童中,手动开始之前,眼睛运动已经开始.

结论:

眼会影响运动规划和执行,特别是在对象操纵任务期间.
增加的固定时间表明,难以处理视觉信息用于眼的运动反应.
研究结果证实,在患有野视的儿童中,有显著的视觉运动控制缺陷.

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
