姿勢で気分は変わる？タブレットを立てて背すじがのびた人は前向きに、200人の実験

How You Hold a Tablet May Shape Your Mood and Choices

音声・ゲームはこちらから

1Researchers at McGill University in Canada have found that sitting up straight while using a tablet may slightly improve people's mood and lead to better choices in a game. The study appeared in the British Journal of Psychology. The university announced the results in August.

2Nearly 200 people from the university community took part. They were told that they were testing a mobile app, but the real question was how their posture affected them. In one group, the tablet sat on a stand on an adjustable table, which made people sit upright. In the other, the tablet lay flat on a lowered desk, so people hunched over it. Video software measured the angle of each person's neck to check their posture.

3Next, the participants played a computer game in which they pumped up a virtual balloon. Every pump added money, but if the balloon burst, they lost everything they had earned in that round. They could stop and keep their money at any time.

4Over the course of the game, the upright group took greater risks and tended to earn more. Jorge Armony, the senior author of the study, said these players were not acting more impulsively but were choosing a more effective strategy. The upright group also reported significantly stronger feelings of pride, which are linked to a positive mood.

5The study was also designed to avoid a problem with earlier research on power poses, in which people may have guessed what was being tested. In interviews afterward, most participants said they had not noticed that their posture was being changed. Armony said the effects were small and were seen only in a lab, and that changing posture is unlikely to transform someone's life.

全文訳

1カナダのマギル大学の研究者たちが、タブレットを使うときに背すじをのばして座ると、気分が少しよくなり、ゲームでよりよい判断ができるかもしれないことを見つけました。この研究は、英国心理学会の学術誌に掲載されました。大学は8月に、その結果を発表しました。

2大学の関係者ら200人近くが参加しました。参加者はスマホ向けアプリを試すと言われていましたが、本当に調べたのは、姿勢が人にどう影響するかでした。一方のグループではタブレットが高さを変えられる机の上のスタンドに置かれ、そのため背すじがのびました。もう一方では、低くした机にタブレットが平らに置かれていたので、背中を丸めてのぞきこむ形になりました。動画のソフトで一人ひとりの首の角度をはかり、姿勢を確かめました。

3次に参加者は、画面の中の風船に空気を入れていくコンピューターゲームをしました。1回空気を入れるごとにお金がふえますが、風船が割れると、その回にかせいだお金はすべてなくなります。参加者はいつでもやめて、お金を受け取ることができました。

4ゲームを通して、背すじがのびたグループはより大きなリスクをとり、より多くかせぐ傾向がありました。研究の責任者のホルヘ・アルモニー教授は、この人たちは衝動的に動いていたのではなく、より効果的な作戦を選んでいたと話しました。背すじがのびたグループは、誇らしい気持ちも目立って強いと答えました。この気持ちは前向きな気分と結びついています。

5この研究は、これまでの「パワーポーズ」の研究にあった、参加者が何を調べられているか察していたかもしれないという問題をさけるようにも作られていました。あとの聞き取りでは、ほとんどの参加者が、自分の姿勢が変えられていたことに気づかなかったと答えました。アルモニー教授は、効果は小さく、実験室の中で見られたものにすぎず、姿勢を変えるだけで人生が大きく変わることはないだろうと話しました。

文法ポイント：前置詞 + 関係代名詞（in which など）

関係代名詞の前に前置詞を置く形。本文の a computer game in which they pumped up a virtual balloon は「その中で風船に空気を入れていくゲーム」（= a computer game which they pumped up a virtual balloon in とは言わない）。which の前の前置詞は、元の文（they pumped up a balloon in the game）から来ている。入試の空所補充の定番。
