概括
语言发育迟缓的儿童可以学习使用形状来学习新词. 这项研究训练了晚谈者 (LTs) 的形状概括,发现他们学会了应用这个词学习策略.
科学领域:
- 发展心理学 发展心理学
- 语言学的语言学.
- 儿童语言的获取儿童语言的获取
背景情况:
- 迟说话的人 (LTs) 经常表现出词汇发展的延迟.
- 这种延迟的一个潜在原因是不典型的词学习策略的使用,如"形状偏差".
研究的目的:
- 为了调查说话迟到的人是否可以获得形状偏差.
- 为了确定是否获得形状偏差可以加速晚说话的人的词汇学习.
主要方法:
- 十四个迟说话的人被随机分配到一个形状训练组或对照组.
- 形状训练组了解到,具有相似形状的物体具有相同的名称.
- 控制组学习了没有形状的真实单词.
主要成果:
- 形状训练组的孩子们成功地基于形状来概括训练的标签.
- 在培训组中没有观察到对形状不熟悉的标签的泛化.
- 对照组显示随机标签扩展,表明没有学习的战略.
- 表达性词汇的发展没有受到培训的显著影响.
结论:
- 迟谈者可以接受训练,以获得和利用形状偏差.
- 获得形状偏差有助于学习标签的概括.
- 需要进一步的研究来探索形状偏差训练对整体词汇加速的影响.

Lateralization
314
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.

Language Development
327
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...

Stereotype Content Model
14.0K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

The Representativeness Heuristic
15.8K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Concepts and Prototypes
118
The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Labeling Emotion
116
Emotional labeling is a cognitive process that involves identifying and naming one's emotions, such as anger, fear, happiness, or sadness. It allows individuals to recognize and express their internal emotional states, a critical aspect of emotional regulation and communication. Labeling emotions requires more than mere recognition; it also involves drawing upon memory and contextual cues to understand the current situation and apply a corresponding emotional label. For instance, feeling...
