概括
手语经验,而不仅仅是聋,扩大了聋手语者向左阅读的范围. 这种增强的视觉注意力有助于阅读效率,但并不能完全解释聋人观察到的更快的阅读速度.
科学领域:
- 认知心理学 认知心理学
- 语言学的语言学.
- 神经科学是一个神经科学.
背景情况:
- 聋和手语经验影响视觉注意力分布.
- 阅读跨度大小,阅读的视野,通常是不对称的.
- 与听力阅读者相比,聋人手语阅读者表现出更大的向左阅读跨度.
研究的目的:
- 为了确定早期的聋或手语经验是否导致聋手语者左侧阅读范围的增强.
- 为了研究视觉注意力在阅读跨度大小中的作用.
- 为了比较听力无标记者,听力标记者和聋人标记者的阅读效率.
主要方法:
- 凝视条件移动窗口范式用于测量向左阅读跨度.
- 参与者包括听力无标记者,听力早期标记者,以及具有匹配阅读能力的聋早期标记者.
- 阅读效率指标 (率,跳过的单词,回归) 被记录下来.
主要成果:
- 聋人和听力标记者表现出相同的,较大的左向阅读范围 (10个字符),与听力非标记者 (4个字符) 相比.
- 手语经验是扩大向左阅读范围的一个重要因素.
- 聋手语者比听力组表现出更高的阅读效率 (更快的速度,更多的跳过单词,更少的回归) 比听力组.
结论:
- 手语经验有助于更大的向左阅读跨度.
- 聋人手语读者阅读效率的提高不仅仅是由于他们的左侧跨度更大.
- 视觉注意力和阅读处理受到手语学习和聋的显著调节.

01:27Language and Cognition
681
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.

01:28Lateralization
937
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.

01:17Sign Test for Matched Pairs
370
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.

01:25Learning Disabilities
543
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
