概括
脱人格化/脱现 (DP/DR) 症状不会改变视觉感知. 这项研究没有发现PD/DR影响个人如何评价或调整图像现实性的证据,这表明改变的经验是认知性的,而不是感知性的.
科学领域:
- 心理学 心理学 心理学
- 神经科学是一个神经科学.
- 认知科学 认知科学
背景情况:
- 脱人格化/脱现 (DP/DR) 涉及到对现实的主观经验的改变.
- 脱现的特点是脱离环境和改变视觉感知.
- 缺乏实证研究,真正的感知变化在脱现期间是缺乏的.
研究的目的:
- 调查与非个性化/非现实化 (DP/DR) 症状相关的潜在的真实感知变化.
- 确定DP/DR症状是否影响视觉刺激的评估和调整.
- 为了测试假设,在脱现中改变的生动性反映了认知解释,而不是感知改变.
主要方法:
- 进行了两项在线实验,使用各种和和对比度的自然现场图像.
- 参与者 (Exp 1中的N=200,Exp 2中的N=125) 完成了剑桥非个人化量表 (CDS) 的状态版本.
- 实验1评估了主观真实性评级;实验2涉及调整图像对比度/和度以匹配个人经验. 使用贝叶斯模型比较.
主要成果:

Altered States of Awareness
956
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Depth Perception and Spatial Vision
1.7K
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.

Hallucinogens and Psychedelics
555
Hallucinogens are psychoactive substances that profoundly alter perceptual experiences, generating unreal visual and sensory images. Often referred to as psychedelic drugs — a term derived from the Greek words "psyche" (mind) and "delos" (revealing) — these substances include marijuana and lysergic acid diethylamide (LSD), among others. These drugs vary in intensity and effects.

Dissociative Identity Disorder
590
Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...

Visual Agnosia
872
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

Color Vision
1.3K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
