概括
需要处理的信息在编码过程中不能从工作内存中过出来. 即使在事先确定为无关紧要的信息时,这种信息也会被保留,类似于在后面确定时.
科学领域:
- 认知心理学 认知心理学
- 神经科学是一个神经科学.
- 信息处理 信息处理
背景情况:
- 过是工作记忆的关键认知机制,排除不相关的数据.
- 之前的研究集中在过与任务无关的分心因素,而不是需要简要处理的信息.
研究的目的:
- 调查是否需要处理的信息,但不是长期维护,可以在工作内存编码期间过.
- 为了确定工作内存中过机制的极限.
主要方法:
- 设计了一个新的复杂跨度任务,有三个条件:预备 (过是可能的),逆向 (过被阻止) 和控制 (没有分心).
- 记忆性能在各种条件下进行了比较.
- 记忆测量模型 (Oberauer & Lewandowsky,2019) 用于估计分心器的记忆强度.
主要成果:
- 在预备急状态下,记忆表现与后备急状态相似,但比对照状态更差.
- 需要处理的分心信息在工作记忆中显示出类似的保留,无论暗示时间如何 (前与后暗示).
结论:
- 需要处理的信息在编码阶段无法选择性地从工作内存中过出来.
- 对于必须处理的信息,工作记忆的过效率较低,即使没有长期维护.

Encoding
875
Information enters the brain through encoding, which is the input of information into the memory system. Once sensory information is received from the environment, the brain labels or codes it. The information is then organized with similar information and connected to existing concepts. Encoding occurs through automatic processing and effortful processing.
Automatic processing involves the encoding of details like time, space, frequency, and the meaning of words, usually done without conscious...

System of Memory
7.5K
Memory is categorized into three major systems: sensory memory, short-term memory (STM), and long-term memory (LTM). These systems differ in their capacity and the duration for which they can hold information. Sensory memory captures raw sensory input from the environment, holding it for just a few seconds or less. For example, on hearing a brief, loud sound, like a car horn honking, the sound seems to linger in the mind for a moment even after it stops. This is an instance of sensory memory...

Working Memory
927
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...

Long-Term Memory
701
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

Traumatic Memory
593
Emotionally traumatic events often lead to memories that are exceptionally vivid and enduring, sometimes persisting with remarkable clarity throughout an individual's life. A classic example of this phenomenon is a person who survives a car accident. Even years later, they may recall every detail of the event with startling accuracy — the screeching of the tires, the jarring impact, and the acrid smell of burning rubber. Such vividness contrasts sharply with how an individual...

Repressed Memory
529
Repressed memories are a psychological phenomenon where memories of traumatic events are unconsciously blocked from a person's awareness. This process occurs as a defense mechanism, protecting the mind from the emotional impact of distressing or painful experiences. For example, a person who has experienced childhood trauma may grow up with no conscious recollection of the event. In such cases, the memories are thought to be buried deep within the subconscious, inaccessible to the conscious...
