　　Most episodes of absent-mindedness forgetting where you left something or wondering why you just entered aroom-are caused by a simple lack of attention,says Schacter. “You’re supposed to remember something, butyou haven’t encoded it deeply.”

　　Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phonein a pocket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget that the phone is in the jacket now hanging in you wardrobe (衣柜). “Your memory itself isn’t failing you,” says Schacter. “Rather, you didn’t give your memory system the information it needed.”

　　Lack of interest can also lead to absent-mindedness. “A man who can recite sports statistics from 30 years ago,” says Zelinski, “may not remember to drop a letter in the mailbox.” Women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on justthat.

　　Visual cues can help prevent absent-mindedness, says Schacter. “But be sure the cue is clear and available,” he cautions. If you want to remember to take a medication (药物) with lunch, put the pill bottle on the kitchen table—don’t leave it in the medicine chest and write yourself a note that you keep in a pocket.

　　Another common episode of absent-mindedness: walking into a room and wondering why you’re there. Most likely, you were thinking about something else. “Everyone does this from time to time,” says Zelinski. The best thing to do is to return to where you were before entering the room, and you’ll likely remember.
