拯救腦霧小作戰 I : 用打的? 還是用寫的?

[科學新發現]: 手寫比打字更可能增加大腦的連接。挪威科技大學 1月26日在《心理學前沿》（Frontiers in Psychology）的最新研究表明，與其在鍵盤上打字，手寫(數位觸控筆)可以提高大腦的連接性[1]。

研究方法

研究人員收集了36名大學生的腦電圖資料，這些大學生被反覆提示寫下或輸入螢幕上出現的單詞。書寫時，他們使用數位觸控筆直接在觸摸屏上用草書書寫。當受試者手寫時，不同的大腦區域連通性有增加的趨勢，但打字時則無。研究人員也表示，當在紙上使用真正的筆時，結果預計是相同的。

原因: 書寫時，手指運動促進大腦的連接

反覆敲擊鍵盤的簡單動作，對大腦的刺激相對較小，研究人員van der Meer解釋:

“我們的研究結果表明，使用筆時通過精確控制的手部運動獲得的視覺和運動資訊對促進學習的大腦連接模式做出了廣泛貢獻。…

大腦活動的差異與手寫時字母的仔細形成有關，同時更多地利用感官，”

手寫過程，增加了頂葉大腦區域間的連接，而這些區域涉及感覺和運動處理，以及中樞區域，區域間的這些特定波與記憶形成和編碼有關。

其他科學家的解釋

加州大學默塞德分校的神經科學家Ramesh Balasubramaniam說:

“以前的大量研究表明，手寫可以提高拼寫準確性、記憶力和概念理解力。科學家們認為，追蹤字母和單詞的緩慢過程使個人有更多時間來處理材料和學習。”

[按] 讀研時，有三問:

[問]: 那麼如果加入「語音輸入」，結果會怎樣?

[問]: 中文手寫會比英文字母手寫更刺激腦神經元連結?

[問]:「聽」的語音刺激: 真人說話和數位語音對腦神經元連結又有何不同?

A little battle to save brain fog I: By typing? Or by writing?

To Write Or To Type is a question of brain connections

Handwriting is more likely to increase brain connections than typing. The latest research from the Norwegian University of Science and Technology in Trondheim published in Frontiers in Psychology on January 26 shows that instead of typing on a keyboard, handwriting (digital pen) can improve brain connectivity.

Research Methods

The researchers collected EEG data from 36 college students who were repeatedly prompted to write or type words that appeared on a screen. To write, they use a digital pen to write in cursive directly on the touch screen. Connectivity in different brain regions increased when subjects wrote by hand, but not when they typed. The researchers also said the results were expected to be the same when using a real pen on paper.

Reason: When writing, finger movements promote brain connections

The simple act of repeatedly typing on a keyboard causes relatively little stimulation to the brain, explains researcher van der Meer: the visual and motor information acquired through precisely controlled hand movements when using a pen makes a broad contribution to the brain connectivity patterns that facilitate learning. 

Differences in brain activity are related to how carefully letters are formed when handwriting is done while making greater use of the senses. The process of handwriting increases connections between areas of the parietal brain involved in sensory and motor processing, as well as central areas where these specific waves are associated with memory formation and encoding.

Other Scientists’ Explanations

Ramesh Balasubramaniam, a neuroscientist at the University of California, Merced, explained that extensive previous research has shown that handwriting improves spelling accuracy, memory and conceptual understanding. And scientists believe that the slow process of tracing letters and words gives individuals more time to process the material and learn.

[Q]: So what will happen if "voice input" is added?
