概括
马尔莫塞特子表现出齐夫的简短定律,这是一个语言模式,频繁的呼叫更短. 这表明声学统计规律,就像人类语言中的规律一样,可能起源于非语言灵长类动物的声系统.
科学领域:
- 灵长类动物的沟通方式
- 语言学的语言学.
- 生物声学是一种生物声学.
背景情况:
- 人类语言表现出统计规律,例如Zipf的简短定律,其中频繁的单词较短.
- 目前尚不清楚这些语言规律是否早于人类语言,并且存在于非语言灵长类动物的发音中.
研究的目的:
- 为了调查Zipf的简短法则在子子的发音中的存在.
- 为了确定语音统计规律是否可以在非语言灵长类动物的通信系统中出现.
主要方法:
- 一个声调调节范式被用来检查大黄蜂声调效率.
- 松鼠被赋予了选择其发声的自由,以观察新出现的模式.
主要成果:
- 松鼠表现出声压缩策略,包括增加呼叫率和减少呼叫时间.
- 统计分析揭示了声格模式与齐夫的简短法则一致的松鼠.

01:24Components of Language
308
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

01:22Language Development
393
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...

01:27Language and Cognition
367
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.

194
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...

01:10Higher Mental Functions of the Brain: Language
903
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...
