Working Memory01:24

Working Memory

156
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

631
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

科学领域:

  • 认知神经科学 认知神经科学
  • 眼科医生 眼科 眼科
  • 心理学 心理学 心理学

背景情况:

  • 眼动在记忆回忆和视觉想象中的作用是活跃的,但尚未完全理解.
  • 在认知任务期间,眼动的内部合需要进一步调查影响因素.

研究的目的:

  • 研究工作负载,空间参考可用性和想象的运动方向如何影响内部合的眼睛运动.
  • 为了确定眼睛的运动是否是由听觉线索驱动的,或者在视觉空间任务中与内部表示保持一致.

主要方法:

  • 一个视觉空间工作记忆任务,涉及在矩阵内的补丁的心理运动.
  • 操纵工作负载 (矩阵大小),空间参考可用性 (空白对空矩阵) 和运动方向 (听觉线索).
  • 积极任务性能与控制条件的比较 (积极/被动倾听).

主要成果:

  • 眼睛的运动始终与想象中的补丁运动相匹配,独立于听觉或语义线索.
  • 工作负载影响到瞳孔直径,感知需求和性能,但不影响眼动合.
  • 空间参考可用性改善了眼动合,增加了频率,精度和弹性.

结论:

  • 双眼运动反映了注意力转移到视觉和内部表示的信息,而不仅仅是减少工作负载.
  • 眼睛的运动是在涉及内部表征的认知任务中对注意力方向的自然反应.
  • 这些发现表明,注意力,眼动和内部认知过程之间存在着根本的联系.
