加工

The psychology the processing process will usually divide into the controllability processing process and the automatic processing process, this experiment through to will count along the number research and the inverse number research, further explained along number more participation will be the automatic processing process, but the inverse number more will be the controllability processing process, will need to realize attention.

心理学通常将加工过程分为控制性加工过程和自动加工过程，本实验通过对数数的顺数研究和逆数研究，进一步说明顺数更多参与的是自动加工过程，而逆数更多的是控制性加工过程，需要意识的注意。
