作り笑いの効果は？1回なら気分が上向くことも、10回続けると逆効果も　約1200人の実験

A Fake Smile May Help Once, but Not Again and Again

音声・ゲームはこちらから

1A new study has found that one fake smile can make people feel a little happier. But smiling many times when you don't want to may not help.

2The study was done by the University of Florida in the United States. About 1,200 people took part online. They looked at nice pictures, like kittens and flowers, or unpleasant pictures.

3Some people were asked to smile at the pictures. Others just reacted naturally. Some did this once, and some did it 10 times. Then they said how happy they felt.

4After unpleasant pictures, one fake smile made people a little happier. But when people had to smile 10 times, this good effect became smaller. Some people were also told that they could lose money if they did not follow the rules. When people smiled 10 times and could also lose money, the good effect went away completely.

5The lead scientist once worked at a theme park. He had to smile at every customer there.

全文訳

11回の作り笑いで、人は少しだけ幸せな気分になれることが、新しい研究でわかりました。でも、笑いたくないのに何回も笑うと、役に立たないかもしれません。

2この研究は、アメリカのフロリダ大学が行いました。約1200人がオンラインで参加しました。参加した人は、子ネコや花のような楽しい写真か、いやな写真を見ました。

3写真を見て笑顔を作るように言われた人がいました。ほかの人は、ただ自然に反応しました。これを1回だけした人もいれば、10回した人もいました。そのあと、どのくらい幸せに感じるかを答えました。

4いやな写真のあと、1回の作り笑いで、人は少し幸せな気分になりました。でも、10回笑わなければならないと、このよい効果は小さくなりました。さらに、指示どおりにしないとお金が減るかもしれないと言われた人もいました。10回笑ったうえにお金が減るかもしれないと言われた人では、よい効果がすっかり消えました。

5研究の中心になった科学者は、以前テーマパークで働いていました。そこでは、お客さん全員に笑顔を見せなければなりませんでした。

文法ポイント：make ＋人＋形容詞（人を～にする）

make ＋人＋形容詞で「（人）を～な状態にする」。本文の one fake smile can make people feel a little happier（1回の作り笑いで人は少し幸せに感じる）は make ＋人＋動詞の原形、one fake smile made people a little happier は make ＋人＋形容詞の形。
