概括
年长的成年人与年轻的成年人不同地组织触觉材料体验,由于感官衰退而融合了粗和细粒度的感知,影响了情感相关性.
科学领域:
- 老年学是一门学科.
- 触觉和触觉感知是一种触觉和触觉感知.
- 老龄化心理学的心理学
背景情况:
- 人类通过感知 (例如,粗性,流动性) 和情感 (例如,价值,兴奋) 维度来感知材料.
- 之前对年轻成年人的研究已经确定了这些感知和情感维度之间的系统相关性.
- 老年人经常经历触觉能力的下降,特别是细节感知,这表明物质感知可能与年龄相关的差异.
研究的目的:
- 调查触摸材料的感知-情感组织在年轻人和老年人之间如何不同.
- 为了确定与年龄相关的触觉感知下降是否会影响材料被分类和情感体验的方式.
主要方法:
- 30名年轻人 (平均年龄22岁) 和15名老年人 (平均年龄66岁) 手动探索了25种不同的材料.
- 参与者使用18个感知和9个情感形容词来评价材料.
- 用因子分析来提取每个年龄组的关键感知和情感维度.
主要成果:
- 两个年龄组都发现了类似的潜在感知和情感维度.
- 年长的成年人,与年轻的成年人不同,将粗和细粒度合并成一个单一的感知维度.
- 在年龄组之间对粗度,颗粒度和价值的感知中观察到显著差异;老年人没有显示在年轻人中发现的阳性价值-颗粒度相关性.
结论:
- 年长的成年人与年轻的成年人不同地组织和体验触觉材料的特性,这可能是由于与年龄有关的感官衰退.
- 特定的感知维度 (粗,细粒度) 和它们与情感价值的关系在老年时会发生变化.
- 尽管有感官变化,但感知组织的某些方面,包括精细感知,在老年成人中仍然保留着.

01:11Sensory Perception: Organization of the Somatosensory System
3.0K
The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the...

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.

01:25Factors Affecting Perception
1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...

01:27Tactile and Chemical Senses

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex.

The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...
