The most direct function of this function is that users can play with 1.25, 1.5 or even twice the speed, which improves efficiency and saves valuable time.
Later, in the center of the secondary culture, there appeared many "ghost animals" effect videos made by the double-speed function, which were deeply loved by young people.
There are different reasons behind people choosing "double speed". In the content of entertainment and leisure, uneven quality is an important reason why people choose double speed when absorbing content.
Furthermore, it is to acquire knowledge more quickly and effectively, so as to improve the skills of career development.
However, with the increasing popularity of "two-speed" life, netizens began to discuss what kind of influence this habit would have.
Do the advantages outweigh the disadvantages, or do the disadvantages outweigh the advantages? On the Zhihu, some netizens asked: "Is it harmful to always play videos at twice the speed?"
Some people think that "at the speed of 1.25 times, the sound can be heard more clearly and the speech speed can be faster, which can keep people focused." But 1.5 times or more, some sounds are burnt, which is counterproductive. "
Others said, "Listening to people or doing something is easy to worry, feeling too slow and inefficient; Always feel bored part of the acceleration is not fast enough; Eyes are easy to get tired; Listening to normal double-speed sounds feels slow and easy to fall asleep. "
Regarding the influence of double-speed playback, Li Baoming, a professor at the School of Education of Hangzhou Normal University who has been engaged in the study of brain cognitive function for a long time, thinks that the content should be different first.
