The sixth sense

The "sixth sense" is often said to be a strong feeling that a person has about something or someone. Read about one mother's experience.

I had a feeling ...

Kathy Sansano arrived home from work two months ago at 7:00 in the evening. "Usually, my husband is home before me, but when I got in, his briefcase was there, but he wasn't," recalls Sansano. She just thought that he want to the store for something. Sansano began preparing dinner, but couldn't shake the feeling that something was wrong. "I just started feeling very anxious and had to sit down. Five minutes later my husband phoned to say that our son had been injured in a football game at school."

Luckily, the boy only had a broken wrist, but Sansano still can't explain how she knew something was wrong. "It might have been 'mother's intuition (直觉)'" she laughs. "My son and I have always been very close."

Science points out five basic senses that humans use to experience the world. There is now evidence that human may also own a sixth sense-or an intuition about people or events. Recent studies suggest that insects and animals release odorless(meaning "without any smells") chemicals into the environment to send signal emotions such as fear or aggression (侵略). When another creature of the same kind senses the chemical, certain behavior is caused in that creature; for example, it will prepare to fight or to protect itself.

Scientists believe that humans long ago may have communicated using these kinds of chemical signals. "I walked into the room, and something just didn't seem right." It may be that the person is sensing chemical messages that have been produced by others. Kathy Sansano's husband may have left the house feeling afraid and worried about their son. When Kathy got home, she sensed his worry.
