Is a mental phenomenon by which viewers drive more meaning from the interaction of two sequential shots than from a single shot in isolation. this comes from and experiment done in the early 20the century?

I believe the answer is: The Kuleshov Effect

The Kuleschov Effect was popularized by  Soviet filmmaker Lev Kuleshov  in the early 1900s.
When audiences are presented with two sequential shots, the audiences could make a connection on why the characters felt the emotion that they displayed, and allow them to  drive more meaning from the scenes.
