概括
明确的语音指令有助于中国英语学习者调整他们对元音持续时间和光谱线索的依赖. 益处各不相同,先前的经验影响了英语母音感知结果.
科学领域:
- 获得第二语言的学习.
- 语音学和语音学 语音学和语音学
- 精神声学是一种精神声学.
背景情况:
- 了解第二语言 (L2) 学习者如何感知和产生英语元音对于有效的语言教学至关重要.
- 汉语发言者经常与英语母音对比作斗争,比如 /iː/ vs. /ɪ/,依赖于与母语英语发言者不同的语音线索.
研究的目的:
- 调查中文L2英语学习者如何权衡 /iː/-/ɪ/对比的元音持续时间和光谱线索.
- 探索明确的语音指令在修改暗示权重方面的有效性.
- 为了确定培训的好处是否根据个体学习者的差异而有所不同.
主要方法:
- 一项前后设计研究,涉及48名普通话语言的L2英语学习者.
- 随机分配给一个控制组 (n=23) 和一个实验组 (n=25).
- 强迫选择识别任务使用合成的连续元音;实验组接受了明确的语音指令.
主要成果:
- 最初,学习者主要使用持续时间,具有与L2LP模型一致的显著个体变化.
- 在实验组中,明确的指令减少了对持续时间的依赖,增加了对光谱线索的依赖.
- 具有平衡初始暗示使用和先前沉浸经验的学习者显示出更大的远离持续时间的转移.

Factors Affecting Perception
3.0K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.

Language and Cognition
909
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.

Non-Verbal Cues
393
Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...

Auditory Perception
1.4K
The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the...

Subliminal Perception
934
Subliminal perception refers to the processing of sensory information that occurs below the level of conscious awareness. Researchers study subliminal perception by presenting a stimulus, such as a word or image, very quickly, typically around 50 milliseconds. This rapid presentation is often followed by another stimulus, such as a pattern of dots or lines, which blocks further mental processing of the initial stimulus. As a result, if participants cannot identify the initial stimulus better...

Perceiving Loudness, Pitch, and Location
1.2K
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
