まとめ
子供
科学分野:
- 言語学;発達心理学;認知科学
背景:
- 中国語には、一般的なトーン3サンドゥ(T3S)と形態素固有のTSという2つのトーンサンドゥ(TS)ルールがあります。子供によるT3Sルールの獲得に関する以前の研究では、結果が混在しており、形態素固有のTS獲得の理解は限られています。
研究 の 目的:
- 中国語を話す子供(4〜6歳)の一般的なT3Sおよび形態素固有のTSルールの理解を調査すること。TSルール獲得の発達軌跡におけるワーキングメモリ(WM)の役割を探求すること。
主な方法:
- 子供たちのT3Sルールおよび形態素固有のTSルールの理解を評価するために、トーンサンドゥ予測処理タスクを利用しました。ワーキングメモリ(WM)容量を測定するためにnバックタスクを実施しました。
主要な成果:
- 子供たちは、6歳児が4歳児と5歳児を上回るパフォーマンスを示し、両方のTSルールを理解する上で発達上の進歩を示しました。ワーキングメモリ容量、特に1バックタスクでのパフォーマンスは、形態素固有のTSルールを処理する子供たちの能力を予測しました。
結論:
- 中国語のトーンサンドゥルールの子供による理解は、年齢とともに発達します。ワーキングメモリは、若い中国語話者における形態素固有のトーンサンドゥルールの獲得において重要な役割を果たします。

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

The Cochlea
50.5K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Language Development

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...

Normal and Tangetial Components: Problem Solving
569
Consider a man with a mass of 70 kg seated in a chair connected to a pin support through a member BC. If the man maintains an upright position, the task is to determine the horizontal and vertical reactions of the chair on the man when the member makes a 45° angle with the horizontal. At this moment, the man has a speed of 5 m/s, increasing at a rate of 1 m/s².

Perception of Sound Waves
5.4K
The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...
