 Professor Reason recently persuaded 35 people to keep a diary of all their absent-minded actions for two weeks. When he came to analyze their embarrassing errors, he was surprised to find that nearly all of them fell into a few groups.

One of the women, for instance, on leaving her house for work one morning threw her pet 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 programme 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（颠倒）in the programme.” About one in twenty of the incidents the volunteers reported were these “programme assembly failures.”

Twenty percent of all errors were “test failures” — mainly due to not verifying the progress of what the body was doing. A man about to get his car out of the garage passed through the back yard where his garden jacket and boots were kept, put them on — much to his surprise. A woman reported, “I got into the bath with my socks on.”

The commonest problem was information “storage failures”. People forgot the names of people whose faces they knew, went into a room and forgot why they were there, mislaid something, or smoked a cigarette without realizing it.

The research so far suggests that while the central processor of the brain is liberated from second-to-second control of a well-practiced routine, it must repeatedly switch back its attention at important decision points to check that the action goes on as intended. Otherwise the activity may be gotten by another frequently and recently used programme, resulting in embarrassing errors.

Applications and utility programs use the services provided by the kernel to provide practical business functionality.

In operating systems such as Windows or most versions of Unix, the kernel (68) everything except application and utility programs.

In microkernel operating systems such as Digital Unix and Apples forthcoming Mac OS Server, the kernel (69) supports only multitasking and memory management. Other services such as applications, utilities and the user interface support device drivers, API and graphics which all (70) outside the microkernel.
