概括
通过第一人称视角体验的体内运动会影响自动姿势控制,模仿一个人自身动作的感觉运动表现. 然而,这种效果是暂时的,在幻觉结束后不会持续下去.
科学领域:
- 认知神经科学 认知神经科学
- 发动机控制器的控制器
- 化身研究研究的体现
背景情况:
- 身体自我代表涉及身体所有权和代理意识.
- 化身幻觉表明,身体所有权可以诱导一种行动意识.
- 之前的研究集中在自愿运动上,让自动感官运动过程未被充分探索.
研究的目的:
- 研究虚拟化身运动的实施 (1PP) 和观察 (3PP) 如何影响姿势控制.
- 为了确定自动传感运动过程是否受到体内运动的影响.
- 检查运动实施方案在静态和动态任务期间对压力中心 (CoP) 的影响.
主要方法:
- 参与者体现或观察到一个虚拟的化身执行单脚.
- 通过测量压力中心 (CoP) 位移来评估姿势控制.
- 实验包括在暴露于实施方案/观察条件期间和之后进行的实验.
主要成果:
- 只有在第一人称视角 (1PP) 实施方案条件下,CoP位移在稳定站立期间与化身坐相连贯地转移.
- 在暴露于1PP或3PP条件后,在稳定站立或双腿坐时没有观察到显著的CoP转移.
- 体内运动与感应运动系统中的自我运动类似,影响全身自动控制.
结论:
- 体内运动由感觉运动系统处理,类似于自我生成的运动,影响自动姿势控制.
- 多感官集成可能支持体现和姿势控制.
- 运动体现对感觉运动系统的影响是短暂的,只持续幻觉的持续时间.

Somatosensation
36.9K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Deindividuation
22.4K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Composite Bodies
1.6K
A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

Virtual Work
1.6K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Impression Management Techniques I: Managing Appearances
296
Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...

Magical Thinking
350
Magical thinking encompasses the belief in assumptions that defy logical reasoning yet appear intuitively convincing. It is a common psychological phenomenon that persists across various cultural and individual contexts. While these assumptions contradict empirical evidence and scientific laws, they often serve meaningful psychological roles in promoting emotional resilience and a sense of control, especially under stress or uncertainty.Thought-Action Fusion and the Law of SimilarityA key...
