Even if we meet, we should not know what it means to be covered in dust and have frosty temples.

This poem is from Su Dongpo's Jiang Chengzi. Remember dreams. " The author and his dead wife were separated by Yin and Yang for ten years, and their career was bumpy and hit repeatedly. At this time, it is travel-stained and exhausted. Even if I can really meet in my dream, I'm afraid my wife won't recognize me. Even readers are deeply saddened by this. This poem is a forgotten phenomenon from the psychological point of view. The so-called forgetfulness means that things that have been experienced before can no longer be recognized or recalled, or are wrongly recognized or recalled. Forgetting may be permanent and can never be recognized and reproduced. It may also be temporary, such as forgetting words, not answering the names of acquaintances, remembering knowledge in the examination room, and remembering it when you leave the examination room. It's all temporary forgetfulness There are many different situations in the degree of forgetting, not only in the obvious quantity and quality, but also in the number and time of review required for recovery.

There are many factors that affect forgetting.

The influence of the meaning of memory materials. If the materials on the back are boring and of little significance to study and life, such materials are easy to forget.

The nature of memory materials will also affect the process of forgetting. If students study poetry, prose, essays and expositions at the same time. The strongest memory is poetry, and the fastest forgetting is expository writing. Guildford's research shows that different materials have different forgetting curves, among which meaningless syllables are the easiest to forget. In addition, the process of forgetting is also affected by the amount of materials, which is large and easy to forget.

Interference between forward suppression and backward suppression. The interference of previous learning materials on post-recall learning materials. Backward inhibition refers to the interference of post-learning materials on maintaining and recalling pre-learning materials. When reciting the text, we all have this experience. We remember the beginning and end firmly, but the middle part is relatively poor. This is because the beginning part is disturbed by backward vision inhibition, the end part is disturbed by forward vision inhibition, and the middle part is disturbed by forward vision inhibition and backward vision inhibition at the same time. Therefore, in order to forget unnecessarily, we should pay special attention to the negative effects of two kinds of inhibition in the memory process.

In real life, forgetting is not all bad. Those unpleasant past events and painful experiences can be forgotten, which is of great practical significance to improve mental health and work efficiency.
