10 Second Tip: Always Anticipate
AnticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation. The anticipat... More is one of the Principles of Animation, but where and when should it be used? Does every action need an anticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation. The anticipat... More? Does it really make a difference?
To answer that last question first: Absolutely. All the principles are important, of course, but anticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation. The anticipat... More has a way of getting more bang-for-your-buck than almost any other technique. The reason for this has to do with your relationship with the audience.
As an animator, your job is to entertain the audience, and one of the best ways to do that is to subconsciously lead them towards whatever comes next. As human beings, we enjoy a natural feeling of anticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation. The anticipat...

Any time you move a character, it pays to give a little visual-nudge to the audience and say “hey, something’s about to happen.”
You don’t have to go crazy here. Not every anticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation. The anticipat... More needs to be the textbook “wind up before the pitch” style movement.

As Mariel Cartwright explains in this video on Animation for Games, even one frame of anticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation.

No matter what your next animated movement is, try out a little anticipationPreparing a motion by first going into the opposite direction to build up momentum is called anticipation. The anticipat...

What do you mean? A source for this claim? Hmm… I don’t know a good scientific proof for this, I can only speak from experience. Any medium or fast action without anticipation can be really hard to catch and might be perceived as “too much” at once.
