概括
脸上的点可能会引起厌恶,而不是恐惧,正如学生的反应所示. 瞳孔收缩到脸上的点与对照人群没有显著差异,但恢复速度更快.
科学领域:
- 心理学 心理学 心理学
- 神经科学是一个神经科学.
- 生理学 生理学 生理学
背景情况:
- 在自然背景上的点触发与副交感激活相关的瞳孔收缩,暗示厌恶.
- 虽然众所周知,面部上的点会引起比非面部背景更强烈的厌恶,但对瞳孔收缩的直接比较仍然不清楚.
研究的目的:
- 为了调查面部上的点是否与非面部背景相比引起更强烈的瞳孔收缩.
- 探索对面部点的反应中寄同情和同情神经系统活动的作用.
主要方法:
- 瞳孔测量用于测量瞳孔大小变化.
- 参与者看到了面部呈现的点,相位乱的面部 (光度和空间频率控制),以及面部单独的刺激.
主要成果:
- 观察到面部点和相模糊面部的初始瞳孔收缩,但与对照组相比没有显著差异.
- 瞳孔对面部点的反应恢复到基线的速度比相位混的面部更快,在后期阶段瞳孔尺寸更大.
结论:
- 这些发现表明,无论背景如何,点可能会激活副交感神经系统,可能引起厌恶而不是恐惧.
- 交感和副交感活动之间的动态相互作用可能解释了观察到的瞳孔反应恢复和大小的差异.

01:24Vision
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
01:20Anatomy of the Eyeball
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle layer, the vascular tunic,...
