概括

这项研究表明,语义漂移在单词关联任务中迅速发生,单词频率影响早期反应. 在25秒的任务中观察到语义漂移和单词频率效应.

科学领域:

认知心理学认知心理学
计算语言学计算语言学
心理语言学心理语言学

背景情况:

语义漂移,词语意义随时间的变化,通常在较长的时间内进行研究.
语言和定位模拟 (LASS) 理论在认知中提出了不同的语言和模拟系统.
单词频率效应 (WFE) 表明,更频繁的单词被处理得更快,更早.

研究的目的:

在一个短暂的,定时的词汇关联任务 (25秒) 中调查语义漂移.
检查单词频率效应 (WFE) 对早期单词关联的影响.
测试LASS理论关于语言与模拟系统激活的预测.

主要方法:

参与者完成了一个定时的词汇关联任务,使用五个提示词 (树,狗,质量,塑料,爱).
使用GloVe嵌入和BERT.使用GloVe嵌入和BERT.生成的关联被分析为语义距离 (共乘相似性).
WordNet 语法集被用来评估跨时间四分位数的语义多样性和独特性.

主要成果:

从第一个到第四个时间四分位数观察到显著的语义漂移,支持LASS.
工会的多样性是显而易见的,早期的协会显示多样性减少和更高的频率.
效果大小在提示词之间有所不同,这表明位于模拟强度的差异.

结论:

语义漂移甚至可以在短时间,分钟以下的词汇关联任务中检测到.
这些发现支持LASS理论,并为WFE提供了一个时间维度.
词汇关联任务提供了一个可扩展的方法来研究语义变化和认知过程.

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Interference and Decay

Interference and Decay

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...

Tip-of-the-Tongue Phenomenon

Tip-of-the-Tongue Phenomenon

The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...
