- 人类的记忆 人类的记忆
背景情况:
- 注意力和记忆力是内在相关的认知功能.
- 注意力提升效应 (ABE) 表明,与目标相关的刺激在编码过程中更好地被记住.
- ABE还影响识别,在检索过程中,与目标相关的刺激更容易被识别为"旧".
研究的目的:
- 研究目标检测如何影响识别记忆的潜在机制.
- 要区分目标检测对内存检索和内存编码的影响.
主要方法:

01:12Retrieval

Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

140
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...
