- 人与计算机的交互
背景情况:
- 视觉工作记忆 (VWM) 研究传统上使用静态显示器与突然移除对象.
- 现实世界VWM涉及由于自我运动或物体运动而逐渐消失的物体.
- 已经确定的VWM发现对自然情景的概括性仍然不清楚.
研究的目的:
- 调查VWM的经典发现,包括容量限制和基于空间的选择,是否适用于自然主义的物体消失模式.
- 为了比较VWM在静态,突然移除条件下的性能与动态,逐渐消失条件的性能.
- 评估改变空间关系对VWM的影响.
主要方法:
- 利用虚拟现实 (VR) 来模拟静态 (突然移除) 和流动 (逐渐消失) 条件.
- 参与者在两个模拟环境中执行VWM任务.
- 测量VWM容量和分析视线方向,以证实基于空间的记忆力选择.

Working Memory
375
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Eyewitness Memory
135
Eyewitness memory refers to the recollection of events by someone who has directly witnessed them, often serving as critical evidence in legal settings. This type of memory is commonly used in criminal cases where a witness describes details like a suspect's appearance, clothing, or behavior during a crime. However, despite its perceived reliability, eyewitness memory is prone to significant errors.
One such error is memory distortion, which occurs because human memory does not function...

Visual Agnosia
237
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...

Perceptual Constancy
441
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Sensory Memory
252
Sensory memory captures information from the environment in its original form for a very brief duration, just long enough to be exposed to visual, auditory, and other senses. This type of memory is detailed and rich but quickly lost unless certain strategies are employed to transfer it into short-term or long-term memory. Sensory information is continuously bombarding the human brain, yet only a small fraction is absorbed, as most of it does not significantly impact daily life. For instance,...

Implicit Memories
152
Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
