スマホで記憶力が低下?カギは「時間」より「使い方」 ハンガリーの大学の研究
It May Be How You Scroll, Not How Long
1Young adults who spend hours scrolling through content on their phones scored lower than expected on memory and attention tests, a study in Hungary has found. Semmelweis University in Budapest, which ran the study, said how people use their phones may matter more than how long they use them.
2The study, published in the journal Acta Psychologica, looked at university students aged 18 to their mid-30s. Inc. magazine reported that 225 students took part. They filled out online questionnaires about their phone use, such as whether they had missed planned tasks because of their phones. They also took memory and attention tests and had their bodies measured.
3Based on their habits, the students were divided into three groups. One group used phones mainly to keep in touch with people. Another mixed messaging with news, entertainment and scrolling but stayed under about four to five hours a day. The third group, about one third of the students, used phones for four to five hours or more a day, mostly to consume content rather than to communicate.
4The heavy-scrolling group slept worse and found it harder to stop themselves from checking their phones. The researchers also found that a nervous personality alone did not make someone addicted to their phone. Low self-control and a strong fear of missing out, or FOMO, mattered more. Total time on phones was linked mainly to physical effects, such as neck strain from looking down.
5The results show a link, not proof that scrolling causes weaker memory. The researchers did not suggest giving up smartphones. They suggested turning off unnecessary notifications, limiting time on social media and avoiding phones before bed.

全文訳
1スマホで何時間もコンテンツをスクロールして見ている若い大人は、記憶と注意力のテストで予想より低い点数だったことが、ハンガリーの研究でわかりました。研究を行ったブダペストのセンメルワイス大学は、スマホをどのくらい長く使うかより、どう使うかのほうが大事かもしれないと述べました。
2学術誌『アクタ・サイコロジカ』にのったこの研究は、18歳から30代半ばの大学生を調べました。アメリカの雑誌Inc.によると、225人の学生が参加しました。学生たちは、スマホのせいで予定していたことをやりそこねたことがあるかなど、スマホの使い方についてのオンラインのアンケートに答えました。記憶と注意力のテストを受け、体の測定もしました。
3習慣をもとに、学生は3つのグループに分けられました。1つのグループは、おもに人と連絡をとり合うためにスマホを使っていました。別のグループは、メッセージにニュースや娯楽、スクロールをまぜて使っていましたが、1日約4〜5時間より少ない時間でした。3つ目のグループは学生の約3分の1で、1日4〜5時間以上スマホを使い、そのほとんどは人とやりとりするより、コンテンツを見ることに使っていました。
4長くスクロールするグループは、睡眠がよくなく、スマホを確かめるのをがまんしにくいと感じていました。研究者たちは、不安になりやすい性格だけでは、スマホに依存するわけではないこともわかりました。自分をおさえる力が弱いことと、「取り残されるのがこわい」という気持ち(FOMO)が強いことのほうが、大きく関係していました。スマホを使う時間の合計は、おもに、下を向くことによる首の負担のような、体への影響と関係していました。
5この結果が示しているのは関係であって、スクロールが記憶力を弱くするという証拠ではありません。研究者たちは、スマホをやめることはすすめませんでした。かわりに、いらない通知を切ること、SNSの時間を決めること、寝る前にスマホを使わないことをすすめました。
文法ポイント:間接疑問(how + 主語 + 動詞 / how long + 主語 + 動詞)
疑問詞のあとを〈主語 + 動詞〉のふつうの語順にすると、文の一部(名詞のかたまり)として使える。本文の how people use their phones may matter more than how long they use them では、how people use their phones(人がスマホをどう使うか)が主語、how long they use them(どのくらい長く使うか)が than のあとに来ている。疑問文の語順(how do people use)にしない点に注意。
