Comment on Cesana-Arlotti et al. (2018)

The origins of logical concepts is one of the central topics in cognitive science. Cesana-Arlotti and colleagues provide novel eye-tracking measures from preverbal infants compatible withdisjunctive reasoning. However, the evidence is not conclusive. We provide a simpler object tracking account that would produce the same processing signatures. Future research must make a priori predictions that distinguish these accounts.
