Why FACS Coding Is Harder Than It Looks

Описание: 00:00 – Let’s talk about AUs (I’m not reciting the manual)
00:14 – What I’m actually doing: how to practise AUs and why it matters
00:27 – For me, FACS is about empathy, mentalizing, perspective-taking
00:58 – Why practising matters more than mechanically meeting criteria

01:14 – The scoring rules problem (and why nobody really follows them)
01:23 – Reality: most people reduce FACS (mFACS / modified schemes)
01:49 – Labour, cost, and why automation keeps coming up
02:09 – Automation attempts and why they’re methodologically shaky

02:22 – Quick tour of core AUs (with practice notes, not perfection)
02:30 – AU1 & AU2: inner and outer brow raise
02:43 – AU4: brow lower (adults don’t reliably separate components)
03:15 – AU5: upper lid raise
03:26 – AU6: constant arguments, anatomy matters, manuals aren’t neutral
04:14 – Facial anatomy differences and why appearance ≠ muscle action

05:12 – Inter-rater disagreement is normal (that’s why agreement stats exist)
05:28 – Important rule: never see other coders’ scores first

05:54 – AU7: lid tightener
06:06 – AU8: compound movement, manual vs reality
06:19 – AU24 & AU26: lip press vs jaw relax and why people confuse them

06:51 – AU9, AU10, AU11: subtle distinctions, lots of disagreement
07:29 – AU12 & AU13: smiles aren’t simple
07:52 – AU14: buccinator and the “resting 12” problem

08:46 – AU15–AU18: lower-face movements
09:18 – AU20 & AU21: platysma, watch the neck
09:33 – AU22–AU24: compound effects and overcoding risk

10:58 – Beginner trap: overcoding, then learning to dial it back
11:18 – AU25 & AU26 revisited: anatomy changes everything
12:26 – You don’t memorise FACS, you reference it

12:43 – The bigger issue: FACS as a methodological minefield
13:20 – Rules that don’t always hold (38 vs 39, 26 vs 28, etc.)
13:42 – The manual isn’t the Bible

13:59 – What FACS really is: small-sample R&D from the 1970s
14:30 – Contemporary work filling the gaps (anatomy differences, updates)
15:00 – Learn FACS if you must, then move beyond it

15:25 – Next video: real coding
