概括
将随机抽样与双语婴儿的高成年语音抽样进行比较,可以发现语言环境估计的差异. 高成年语音采样捕获了更多的语言混合和儿童定向语音 (CDS).
科学领域:
- 儿童语言习得 儿童语言习得
- 发展语言学是发展语言学.
- 语音语言病理学 语言病理学
背景情况:
- 儿童语言成绩受到环境因素的影响,如双语接触,电子媒体和儿童指导言语 (CDS).
- 之前的研究利用一天的录音和手动注释来研究这些语言环境预测因素.
- 分析这些记录的采样方法可能会影响研究结果.
研究的目的:
- 为了比较两种常见的抽样方法的有效性:随机抽样和基于高成年语音的抽样.
- 为了确定这些采样方法是否产生不同估计的双语婴儿的语言行为.
- 为研究人员提供信息,帮助他们为特定的研究问题选择合适的采样技术.
主要方法:
- 分析了37个西班牙语-英语家庭与婴儿 (4-22个月) 的全天录音.
- 使用两种方法提取样本:随机抽样和基于高成年语音的抽样.
- 标注语言,CDS,电子媒体,社会背景,轮流和婴儿的样本.
主要成果:
- 在大多数行为 (16/17措施) 中,两种采样方法之间发现了高度的相关性和一致性.
- 基于高成年语音的抽样产生了更高的语言混合,CDS和对话转折的估计.
- 随机抽样结果为电子媒体存在和一对一的社会背景提供了更高的估计.
结论:
- 随机和高成年语音采样方法在很大程度上可靠地估计双语婴儿的语言行为.
- 采样方法的选择应以具体的研究重点为指导,因为每个方法都突出了语言环境的不同方面.
- 了解这些差异对于准确解释早期语言发育研究至关重要.

Language Development
359
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...

Random Sampling Method
11.1K
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...

Group Design
8.9K
The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...
