I think sometimes we get carried away with our wonderful tools like lmer().

For this data:
a) in the Classifier construction, it is very clear that Agent favors
Handling, compared to No Agent
b) in the Lexical Item construction, there is no evidence of an effect
of Agent/No Agent on Handshape (because Handshape is largely or
totally invariant*)
You can call this an interaction between Agent and Classifier, if you wanted...
*Are all three 1's "added" or is one of them real?
Either way, you're very close to a situation where Handling only
occurs in one of the four cells, only in Classifier/Agent.
I don't think an extreme distribution like that lends itself to (aka
needs) ordinary quantitative regression analysis (and it's also not
clear how there _could be_ a Subject effect).
Just my two cents,
Daniel
