Review for NeurIPS paper: Language as a Cognitive Tool to Imagine Goals in Curiosity Driven Exploration

Neural Information Processing Systems 

Additional Feedback: Line-by-line comments: Figure 1 - This figure is quite cluttered. I would recommend removing/simplifying some of the graphics (e.g. the thought bubbles) and, when possible, moving them outside the environment canvas. Line 37 - Do the citations on lines 38-39 substantiate the preceding claim that language actually influences children's exploration behavior? This seems like a very difficult claim to test, how do you disentangle mental maturity with language acquisition? Note that I do not consider children "narrating their ongoing activities" to be a meaningful change in behavior if it is not accompanied by a change in how the children actually complete those activities.
