概括
双语者很容易学习并回忆出每个语言的独特语音运动计划,即使感觉运动需求不同. 这种特定于语言的学习抵消了听觉反的改变,并且在它们被移除后仍然存在.
科学领域:
- * 认知神经科学 认知神经科学
- * 语音产生和运动控制
- *双语和学习第二语言.
背景情况:
- * 感官运动学习和记忆回忆是上下文依赖的,主要研究肢体运动.
- *语音产生涉及复杂的运动控制,受任务相关环境的影响.
- *双语者可能会在第一 (L1) 和第二 (L2) 语言之间出现干扰,影响语音表示.
研究的目的:
- * 调查双语者是否可以根据生产语言来获取和回忆不同的语音声音的感觉运动计划.
- * 为了确定语言背景是否会影响言语中运动学习的特异性.
- *将发现与预测双语语音学习广泛干扰的理论进行对比.
主要方法:
- * 参与者在经历实时,语言特定的听觉反变化时产生交错的英语和法语句子.
- * 听觉反变化在语言之间大小相同,但方向相反.
- *实验测试了学习持久性和对语言背景 (句子生成) 的特异性.
主要成果:
- *双语者在演讲中表现出语言特异性的感觉运动学习,适应和抵消听觉反变化.
- *即使在反改变被删除之后,这种学习适应仍然存在.
- *学习是特定于语言背景 (句子生成语言) 的,并没有观察到非语言线索.
结论:
- *双语者可以获得和回忆高度特定的语音运动表现,根据生产语言量身定制.
- * 感官运动语音学习取决于上下文,并且可以是特定于语言的,挑战广泛的L1-L2干扰理论.
- *语言之间对比的感觉运动需求不一定会导致干扰,但可以促进精确的运动学习.

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

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.

Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

677
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

01:14Piaget's Stage 1 of Cognitive Development
594
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.
