概括
当方法发生变化时,评估儿童发育是很棘手的. 这项研究发现,婴儿的寻找行为和年龄较大的孩子的指针准确度有很强的相关性,这表明一种统一的方式来跟踪单词学习的发展.
科学领域:
- 儿童发展 儿童发展
- 认知心理学 认知心理学
- 语言学的语言学.
背景情况:
- 发育研究经常使用不同的年龄组不同的措施 (例如,婴儿看与学龄前儿童指).
- 这种差异使得评估语言学习等技能中持续的发育变化变得更加复杂.
- 连接这些不同的措施的经验数据很少.
研究的目的:
- 调查婴儿寻找措施和学龄前儿童指向措施在词语学习任务中的关系.
- 为了确定婴儿看的行为是否可以预测新兴的知识错过了指向措施.
- 为评估发展轨迹提出一个更具凝聚力的方法.
主要方法:
- 分析了来自914名儿童 (年龄为2.5-6.5岁) 的数据,这些数据来自36项文字或声音学习实验.
- 使用了两个替代选择测试试验.
- 比较看的比例 (婴儿) 与指的准确性 (年长的孩子).
主要成果:
- 在寻找比例和指向精度之间观察到强烈的正相关性 (r=0.7).
- 与"先看"假设相反,看行为没有显示出对知识的敏感性,指针准确性错过了.
- 当指向精度是随机的时,看的比例也是随机的,表明并行灵敏度.
结论:
- 这种强烈的相关性表明,看和指的措施可能反映了词语学习中共同的潜在发展过程.
- 在这种情况下,婴儿寻找行为并不是比指向准确度更敏感的知识前体.
- 这些发现支持一种潜在的方法途径,用于更持续地评估早期词汇获取中的发育变化.

Language Development
329
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 and Cognition
339
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.

The Nativist Approach
38
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...

Piaget's Theory of Cognitive Development from Childhood into Adulthood
101
Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.

Observational Learning
154
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Piaget's Stage 2 of Cognitive Development
66
The preoperational stage, the second of Jean Piaget's four stages of cognitive development, spans approximately ages 2 to 7 and is characterized by the emergence of symbolic thinking. During this stage, children use language, images, and symbols to represent objects and concepts, enabling them to engage in imaginative and pretend play. This symbolic thinking supports children's ability to perform make-believe actions, such as imagining a broom as a horse or their hand as a phone,...
