What does Ma Dongmei Horse mean? What does Ma Dongmei winter mean in May and Ma Dongmei in May?

It means that a person has a bad working memory. This is a clip from the movie Goodbye Mr. Loser, which refers to an "interrupted" uncle who still can't remember his name after listening to it many times. This is a typical example of poor working memory.

The fragment is as follows:

Charlotte: Grandpa, do the Ma Dongmei family live in Room 322 upstairs?

Grandpa: Ma Dong what?

Charlotte: Ma Dongmei.

Grandpa: What winter plum?

Charlotte: Ma Dongmei.

Grandpa: What is a horse?

Charlotte: OK, Grandpa, please calm down first.

Working memory has three obvious characteristics:

First, the time is short. Working memory exists in seconds, just like the cache of a computer. If this information is not used, it will naturally decay over time.

Second, the capacity of working memory is limited. Scientists believe that the average person's working memory length is 7 2 memory units, that is, 5-9.

The third characteristic of working memory is anti-interference.
