概括
学习注意力抑制,有助于避免分心因素,只相对于眼睛 (视网膜坐标) 运行. 这种学会的抑制在眼睛运动后不会转移到基于世界的 (空间的) 坐标.
科学领域:
- 认知神经科学 认知神经科学
- 视觉注意力 视觉注意力
- 感知学习学习是感知学习.
背景情况:
- 过去的经历塑造了注意力,导致学会抑制高概率的分散注意力的位置.
- 目前尚不清楚这种学会抑制是视网管 (以眼为中心) 还是空间管 (以世界为中心).
研究的目的:
- 为了调查学习的注意抑制是否在视网膜或空间坐标中运作.
- 为了确定是否学会了抑制转移在不同的参考框架后眼动.
主要方法:
- 参与者在学习阵列中学习了高概率 (HP) 干扰器位置.
- 凝视被转移到测试阵列中,创建了视网膜和空间膜对应的原始HP位置.
- 对注意力抑制进行了测量,以评估坐标框架偏好.
主要成果:

Association Areas of the Cortex
8.9K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Anatomy of the Eyeball
9.4K
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...

The Retina

The retina is a layer of nervous tissue at the back of the eye that transduces light into neural signals. This process, called phototransduction, is carried out by rod and cone photoreceptor cells in the back of the retina.
