概括
与母语 (L1) 相比,双语者在第二语言 (L2) 中进行创造性思维时经历的认知干扰较小. 这表明,通过减少心理干扰,双语可能为创造性任务提供优势.
科学领域:
- 认知神经科学 认知神经科学
- 心理语言学 心理语言学
- 创造力研究 创意研究
背景情况:
- 人类的创造力在很大程度上涉及语言的理解和生产.
- 双语是普遍存在的,但它对创意产出的影响仍然没有得到充分的研究.
- 双语者增强的抑制控制可能会影响创造性想法评估.
研究的目的:
- 研究操作语言如何影响双语个体的创造性产出.
- 在L1与L2.2的创意任务中检查认知干扰和神经振荡.
主要方法:
- 使用修改的替代用途任务 (AUT) 与波兰语 (L1) - 英语 (L2) 双语.
- 在任务周期中评估创意产出 (想法原创性,不寻常性) 和神经活动 (EEG).
- 专注于认知干扰和大脑振荡 (α和β频段).
主要成果:
- 双语者在L2产生不寻常使用的认知干扰较小,而不是L1.
- 思想的独创性并没有受到操作语言的显著影响.
- 右后方阿尔法功率随着任务周期的增加而增加,并行于原创性收益.
- 较低的α功率 (8-10 Hz) 在L1中较高,而L2.2中发生了更大的β脱同步.
结论:
- 在双语中,创意产出在很大程度上不受操作语言的影响.
- 减少L2中的β脱同步表明竞争心理表现的干扰较小.
- 双语者在创造性任务中可能会在他们的L2中经历较少的"语义洪水",而不是他们的L1.

Language and Cognition
340
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Cognitive Learning
237
Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

Lateralization
318
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

High-Level and Low-Level Awareness
258
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Interference and Decay
121
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...

Subconsciousness and No Awareness
233
The concept of subconscious awareness refers to the processing of information below the level of conscious thought, which significantly influences both behaviors and decisions. It is also known as waking subconscious awareness. This complex level of cognition operates without the direct awareness of the individual, facilitating rapid and simultaneous handling of multiple information streams.
An illustrative example of subconscious processing is its role in problem-solving. Often, individuals...
