For young kids, the temptation to cheat is 'tremendous' and 90% peek in these experiments. Even adolescents and adults are tempted in similar situations, says Dr. Lee.

對于兒童來說，偷看的誘惑力是巨大的，因此有90%的兒童在實驗中都偷看了玩具。即便是青少年和成年人在類似的情況下也受到了引誘，李強說。

When the test giver returns to the room, the child is asked if he or she peeked. At age 2, about a quarter of children will lie and say they didn't. By 3, half of kids will lie, and by 4, that figure is 90%, studies show.

測試者回到房間后詢問孩子們是否偷看了玩具。研究顯示，在兩歲的孩子里，大約有四分之一的人會撒謊說他們沒有看過。三歲的孩子有一半會說謊，而到了四歲，這個數(shù)字是90%。
