概括
成年人语音声区分的实验性破坏表明,模两可的语音会损害语音短期记忆 (pSTM). 这种影响是特定于语境的,不支持语音感知缺陷,导致语言障碍中的PSTM困难.
科学领域:
- 认知心理学 认知心理学
- 神经科学是一个神经科学.
- 语言学的语言学.
背景情况:
- 语音任务缺陷是神经发育语言障碍的特征.
- 感知缺陷理论将语音功能障碍与语音处理问题联系起来.
- 从语音感知到语音表现的直接因果关系仍然未确立.
研究的目的:
- 通过实验评估语音声区分和声学短期记忆 (pSTM) 之间的因果关系.
- 调查是否语音感知障碍是语言障碍中观察到的PSTM缺陷的基础.
主要方法:
- 使用自动音频变形技术创建模两可的语音音节.
- 采用一个pSTM任务,参与者用高和低模两可的音节回忆字母名称序列.
- 对成年参与者 (N=36和N=26) 进行了两项实验,以测试回忆能力.
主要成果:
- 在字母名字字母名字对中,高模两可的音节与低模两可的音节相比,回忆精度较低.
- 对于字母名字词形态音节,没有观察到显著的模糊性成本.
- 模两可的效应是具体的,有限的,并没有转移到不可混的项目,不同于语音噪音的发现.
结论:
- 模两可的语音声音通过与语音噪音处理不同的机制明显损害了pstm.
- 这些发现不支持这样的假设,即语音感知缺陷是语言障碍患者pSTM困难的主要原因.

Language and Cognition
349
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.

Interference and Decay
143
Forgetting is a complex cognitive phenomenon influenced by several factors, among which interference and decay are particularly prominent. These processes explain why individuals often struggle to retrieve specific information from memory, leading to lapses in recall that can be observed in everyday situations.
Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...

Tip-of-the-Tongue Phenomenon
147
The tip-of-the-tongue (TOT) phenomenon is a cognitive experience characterized by a temporary inability to retrieve specific information from memory despite having a strong feeling of knowing the information. Although individuals cannot access the target word or detail, they frequently recall related elements, such as its initial letter, syllable count, or context. This partial retrieval often causes frustration, as one might recognize a familiar face or know that a name starts with a specific...

Higher Mental Functions of the Brain: Language
876
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Working Memory
175
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...
