在心脏循环期间,威胁性刺激不会被视为更接近.
科学领域:
- 心理学 心理学 心理学
- 神经科学是一个神经科学.
- 人与计算机的交互
背景情况:
- 之前的研究表明,在心脏静脉抽缩和腹缩期间,威胁性刺激被感知得更强烈,更接近.
- 这些效应可能受到实验设计的影响,特别是刺激和响应措施的自然性.
研究的目的:
- 调查心脏阶段对威胁和距离感知的影响.
- 检查刺激威胁水平和心脏相对感知近距离之间的相互作用.
- 为了在自然,沉浸式的虚拟现实环境中测试这些效果.
主要方法:
- 一项预先注册的研究涉及41名健康的年轻成年人在沉浸式虚拟现实环境中.
- 参与者在不同的距离 (1.5-5.5米) 观看威胁和非威胁的动物,同时记录心电图 (ECG).
- 参与者表示感知刺激的位置,分析了大约29,000项试验.
主要成果:
- 感知到威胁性和非威胁性动物的距离在心脏阶段 (心经收缩和心脏放松) 之间没有显著差异.

01:05Difference from Background: Limit of Detection
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.

01:06Echo
The human ear cannot distinguish between two sources of sound if they happen to reach within a specific time interval, typically 0.1 seconds apart. More than this, and they are perceived as separate sources.
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case, then the...

01:15Depth Perception and Spatial Vision
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.
