Passage 7
Professor Smith recently persuaded 35 people, 23 of them women, to keep a diary of all their absent-minded actions for a fortnight. When he came to analyze their embarrassing lapses(差错)in a scientific report, he was surprised to find that nearly all of them fell into a few groupings. Nor did the lapses appear to be entirely random.
One of the women, for instance, on leaving her house for work one morning threw her dog her earrings and tried to fix a dog biscuit on her ear. "The explanation for this is that the brain is like a computer," explains the professor. "People program themselves to do certain activities regularly. It was the woman’s custom every morning to throw her dog two biscuits and then put on her earrings. But somehow the action got reversed in the program." About one in twenty of the incidents the volunteers reported were these"program assembly failures".
