概括
到24个月,婴儿在语言学习中不再表现出高过渡概率 (HTP) 的优势. 相反,他们努力地绘制出违反这些学习模式的单词,影响早期的语言学习.
科学领域:
- 发展心理学 发展心理学
- 认知科学 认知科学
- 语言学的语言学.
背景情况:
- 婴儿利用过渡概率 (TPs) 学习语言,将高TP (HTP) 单词映射到意义上.
- 这种HTP优势已在18个月以下的婴儿身上得到证实.
研究的目的:
- 为了调查HTP优势是否在24个月大的婴儿中持续存在,随着他们的词汇发展的进步.
- 为了确定对TP的敏感性如何影响幼儿的词引用映射.
主要方法:
- 两组24个月大的婴儿 (N=64) 接受了意大利语的句子,其中包括HTP和低TP (LTP) 词.
- 一项映射任务评估了婴儿学习HTP和LTP单词的能力,以及违反这些统计模式的序列.
主要成果:
- 婴儿在HTP和LTP词语中表现出同等的学习能力.
- 虽然婴儿学习LTP违规类似于LTP单词,他们学习HTP单词比HTP违规更有效.
结论:
- 在24个月后,HTP在语言学习中的优势会减少.
- 幼儿表现出难以映射违反既定HTP模式的单词形式,这表明语言学习策略的转变.

Language Development
367
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...

Associative Learning
370
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.

Cognitive Learning
243
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.

Language and Cognition
346
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.

Purposive Learning
121
E. C. Tolman emphasized the purposiveness of behavior — the idea that much of our behavior is goal-directed. For instance, employees who aim for a promotion work diligently to meet their targets. Tolman argued that when classical conditioning and operant conditioning occur, the organism acquires certain expectations. In classical conditioning, a child might fear a dog because they expect it to bite. In operant conditioning, a person might consistently work overtime because they expect a...

The Nativist Approach
55
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...
