概括
这项研究发现,参与者经常误解自己的心率 (HR),特别是当心率偏高时.
科学领域:
- 心理生理学 心理生理学
- 神经科学是一个神经科学.
- 人与计算机的交互
背景情况:
- 准确的整体感知,或感知身体内部状态,对健康至关重要,并具有诊断潜力.
- 心脏整感准确度 (CIAcc) 测量至关重要,但不同环境中外部感官信息 (外感) 的影响尚未得到充分理解.
- 现有的测量CIAcc的方法可能会被用于表示心率 (HR) 的感觉模式所混.
研究的目的:
- 调查任务环境 (屏幕与屏幕) 的作用. 虚拟现实) 和感官模式 (音频,视觉,音频视觉) 影响心脏整体感知精度 (CIAcc).
- 检查实时心率 (HR) 修改对CIAcc和相关心理措施的影响.
- 引入一种新的,可适应的方法来测量跨不同感官和环境环境的心脏整感受.
主要方法:
- 使用PolarH10 HR监控器开发了一种模式依赖的心脏识别任务,实时改变显示的HR (±15%,±30%,无).
- 采用了50名参与者的混合因素设计,比较了屏幕和VR环境,以及音频,视觉和音频视觉模式.
- 评估了CIAcc,整感觉意识,心身测量,VR存在和经验后反应.
主要成果:
- 参与者显著低估了他们实际的HR,将其与修改后的HR混为一谈,高达30%的变化.
- 任务环境 (屏幕与VR) 没有影响CIAcc,但影响了与头脑相关的测量;感官模式没有影响CIAcc.
- 整合音频反增强了整感觉意识,而更大的VR存在与较低的CIAcc.相关.
结论:
- 开发的心脏整体感应测量方法轻量级,可伸缩,对HR修改敏感.
- 结果表明,虽然环境和模式可能不会直接改变CIAcc,但音频反可以提高对内部状态的认识.
- 虚拟现实存在和CIAcc之间的反向关系凸显了沉浸式环境中生物反应用的潜在挑战和机遇.

01:15Sensory Modalities
1.4K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

01:27Assessment of the Cardiovascular System III: Palpation
369
Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
