This one treats animation principles as cognitive science rather than just art rules. The approach is refreshingly specific: squash and stretch aren't stylistic choices, they're matching what our brains expect from persistence of vision and observed physics. It frames staging as information architecture for human attention limits, and breaks down why anticipation makes motion readable to our predictive processing systems. If you're building animation tools or teaching Claude to critique motion work, the perceptual psychology angle gives you better reasoning foundations than the usual "make it look good" heuristics. The pose-to-pose versus straight-ahead framing as different philosophies is a nice touch for articulating intent.
