How does television content impact children’s behavior? (credit: modification of work by “antisocialtory”/Flickr)
テレビの内容は、子どもの行動にどのような影響を与えるのだろうか。(出典:“antisocialtory”/Flickrの作品を改変)
Have you ever wondered whether the violence you see on television affects your behavior? Are you more likely to behave aggressively in real life after watching people behave violently in dramatic situations on the screen? Or, could seeing fictional violence actually get aggression out of your system, causing you to be more peaceful? How are children influenced by the media they are exposed to? A psychologist interested in the relationship between behavior and exposure to violent images might ask these very questions.

テレビで見る暴力が自分の行動に影響を与えているのかどうか、疑問に思ったことはないだろうか。画面の中の劇的な場面で人々が暴力的に振る舞うのを見たあとは、現実の生活で攻撃的に振る舞いやすくなるのだろうか。それとも、作り物の暴力を見ることが、かえって攻撃の衝動を発散させ、人をより穏やかにしてくれるのだろうか。子どもは、自分が触れるメディアからどのような影響を受けるのだろうか。行動と、暴力的な映像にさらされることとの関係に関心を持つ心理学者なら、まさにこうした問いを立てるかもしれない。
Since ancient times, humans have been concerned about the effects of new technologies on our behaviors and thinking processes. The Greek philosopher Socrates, for example, worried that writing—a new technology at that time—would diminish people’s ability to remember because they could rely on written records rather than committing information to memory. In our world of rapidly changing technologies, questions about their effects on our daily lives and their resulting long-term impacts continue to emerge. In addition to the impact of screen time (on smartphones, tablets, computers, and gaming), technology is emerging in our vehicles (such as GPS and smart cars) and residences (with devices like Alexa or Google Home and doorbell cameras). As these technologies become integrated into our lives, we are faced with questions about their positive and negative impacts. Many of us find ourselves with a strong opinion on these issues, only to find the person next to us bristling with the opposite view.

人間は古代から、新しい技術が私たちの行動や思考の過程に及ぼす影響を気にかけてきた。たとえばギリシャの哲学者ソクラテスは、当時の新しい技術だった文字を書くことが、人々の記憶する力を弱めるのではないかと心配した。人々は情報を記憶にとどめる代わりに、書かれた記録に頼れるようになるから、というのである。技術が急速に変わっていく今の世界では、こうした技術が私たちの日常生活に及ぼす影響や、その結果として生じる長期的な影響について、問いが次々と生まれ続けている。スマートフォンやタブレット、コンピューター、ゲームの画面を見て過ごす時間(スクリーンタイム)の影響に加えて、技術は私たちの乗り物(GPSやスマートカーなど)や住まい(AlexaやGoogle Homeのような機器、ドアベルカメラなど)にも入り込みつつある。こうした技術が生活に組み込まれていくにつれて、私たちはその良い影響と悪い影響についての問いに直面する。私たちの多くは、気づけばこうした問題について強い意見を持っている。ところが、ふと見ると、隣にいる人は正反対の意見を抱いて気色ばんでいる。
How can we go about finding answers that are supported not by mere opinion, but by evidence that we can all agree on? The findings of psychological research can help us navigate issues like this.

単なる意見ではなく、私たちの誰もが同意できる証拠に裏づけられた答えを見つけていくには、どうすればよいのだろうか。心理学の研究から得られた知見は、こうした問題の中で進むべき道を見つける助けになりうる。
