[ed. See also: How Actors Remember Their Lines (Nautilus)
Actors face the demanding task of learning their lines with great precision, but they rarely do so by rote repetition. They did not, they said, sit down with a script and recite their lines until they knew them by heart. Repeating items over and over, called maintenance rehearsal, is not the most effective strategy for remembering. Instead, actors engage in elaborative rehearsal, focusing their attention on the meaning of the material and associating it with information they already know. Actors study the script, trying to understand their character and seeing how their lines relate to that character. (...)

Similarly, when psychologists Helga and Tony Noice surveyed actors on how they learn their lines, they found that actors search for meaning in the script, rather than memorizing lines. The actors imagine the character in each scene, adopt the character’s perspective, relate new material to the character’s background, and try to match the character’s mood. Script lines are carefully analyzed to understand the character’s motivation. This deep understanding of a script is achieved by actors asking goal-directed questions, such as “Am I angry with her when I say this?” Later, during a performance, this deep understanding provides the context for the lines to be recalled naturally, rather than recited from a memorized text. In his book Acting in Film, actor Michael Caine described this process well:
You must be able to stand there not thinking of that line. You take it off the other actor’s face. Otherwise, for your next line, you’re not listening and not free to respond naturally, to act spontaneously. (...)In describing how they remember their lines, actors are telling us an important truth about memory—deep understanding promotes long-lasting memories.
