Being as lazy as possible. We take the everything-the-speaker-said-on-a-trial and count the number of occurances of different classes of words (defined by dictionary / regex).

trying to pick up on “literal” descriptions
“squar|triangle|triangular|diamond|shape|”, “trapez|angle|degree|parallel|rhomb|box|cube|line|white|black”
face|head|heads|back|shoulder|shoulders”, “|arm|arms|leg|legs|foot|feet|body|knee|knees|”, “toe|toes|hand|hands|body|butt|heel|heels|ear|ears|nose|neck|chest|hair
right|left|above|below|under|over|top|bottom|behind|side|beneath
“kick|crouch|squat|kneel|knelt|stood|”, “stand|sit|sat|lying|walk|facing|fall|looking|”, “lean|seat|laying”
woman|man|person|guy|boy|girl|dude|lady
trials where none of the above classes of words appeared (~ abstract only)
