概括
感官反,而不是明显的视觉处理,解释了为什么动作变化不遵循韦伯定律. 在视觉引导的操作中,反减少了对象大小的响应可变性缩放.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 发动机控制器的控制器
背景情况:
- 韦伯定律描述了感知噪声与刺激强度的缩放.
- 这种缩放通常不在视觉引导的操作中,这表明分开的感知-动作处理.
- 这项研究调查了感官反在动作可变性中的作用.
研究的目的:
- 测试是否感官反,而不是分离的视觉处理,解释了韦伯定律在视觉引导的行为中缺乏.
- 为了确定在线和明确的感官反如何影响掌握期间的响应变化.
- 检查性能错误线索是否影响知觉大小估计变化.
主要方法:
- 实验涉及模掌握和手动大小估计.
- 在不同的感官反条件下 (在线视觉,触觉,错误线索) 测量了相对于物体大小的响应变化.
- 没有反的模掌握显示了韦伯定律的缩放;反减少了这种缩放.
主要成果:
- 只有当感官反缺席时,剧掌握的响应变化与物体大小进行缩放.
- 在线视觉或触觉反的存在,甚至在相邻试验中的反,减少了这种扩展.
- 一个视觉错误提示类似地减少了感知大小估计中的变化度量.
结论:
- 感官反调节了运动反应的变化,解释了在视觉引导的行为中韦伯定律的明显缺失.
- 减少缩放与感官反影响的运动映射的适应性变化有关.
- 这表明对感知和行动的统一,反调制的处理,挑战分离处理理论.

Perception
433
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...

Sensory Perception: Organization of the Somatosensory System
2.8K
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...

Factors Affecting Perception
1.5K
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.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

Introduction to Special Senses
5.5K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

Somatosensation
36.4K
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.

What is a Sensory System?
92.8K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.
