How would you abbreviate the term self-actualization during a fast-moving psychology lecture?

The best abbreviation for self-actualization in a fast-moving lecture would depend on the context and what's already been established. Here are a few options, ranked in order of preference:

1. SA: Simple, clear, and widely understood within a psychology context once introduced.

2. Self-act.: A slightly longer but still concise option, useful if you need more clarity than just "SA."

3. Act. (if the context makes it clear you're referring to self-actualization and not something else): This is risky and should only be used if there's no possibility of confusion.

Avoid anything too obscure or potentially ambiguous. The goal is speed and clarity.
