A Practical Experiment
Take a small rectangular piece of paper. Hold on the two sides by length by your both hands and try to apply equal force to outwards by both hands. If it is possible by you to apply equal forces by both hands then the paper should tear into two equal sized pieces, which is practically impossible as your brain can not focus equally on your both hands and equally manage the force exerted by your hands.
Adept-ability and Human multitask-ability
There has been much research on Human multitask-ability. Some research suggests that the human brain can be trained to multitask. One study was conducted to train seven people to perform two simple tasks, either separately or together, and conducted brain scans of the participants. The persons performed poorly at the beginning but, after training, they were able to perform the tasks simultaneously quite efficiently.
Brain scans of the participants indicate that the prefrontal cortex (resides in frontal lobe of brain) of your brain quickened the ability to process information and enabling the individuals to multitask more efficiently. However, the study also suggests that the brain is incapable of performing multiple tasks at one time, even after extensive training. This study further indicates that, while the brain can adept at processing and responding to certain information, it cannot be multitasking in a true sense.
实际的实验
带一个小的长方形纸。坚持双方的长度你的双手和尝试运用等力向外的双手。如果它是可能的您申请等势力的双手然后应撕成2同等大小的块，这几乎是不可能的，为你的大脑不能平等聚焦你的双手和同样管理所施加的力的手。
adept-ability和人类multitask-ability
有很多研究人类multitask-ability。一些研究表明，人类的大脑可以训练任务。一项研究进行了培训七人完成简单的任务，单独或一起，并进行了大脑扫描的参与者。人表现不佳的开始，经过培训，他们能够执行的任务，同时比较有效。
脑部扫描的与会者表明，前额叶皮层（居住在额叶脑）你的大脑加快处理信息的能力和使个人多任务更有效。然而，研究也表明，大脑不能执行多个任务在同一时间，即使在广泛的培训。这项研究进一步表明，虽然脑能善于处理和应对某些信息，它不能在多任务的真正意义。
