The psychological preference not only for familiar caretakers, or food, but also for familiar sounds as well as perhaps even the ability to recognize word boundaries. The article relates directly to this class in that it is an excellent example of the use of perception and memory. Not only does the infant perceive and has to ability to finely distinguish between the sounds of words, but shows the ability to retain and remember that sound over a period of time.

While I agree with the authors intention and find a great deal of the interest in the research represented, I find that by only using this one research example the author fails to meet the burden of proof for his conclusion that infants know when words end and begin. The target word should have been presented inside a long nonsense word strung together to see if the infant could distinguish it, but there was no evidence presented here.

The brevity of the article was both a positive (like) in the sense it was well organized and quickly understood, but also...

He also assumed from this that this innate ability may even be the basis of language acquisition, an possible answer to the "black box" riddle. While a fascinating idea and certainly worth some merit, the limited research failed to truly prove the authors point. Certainly there is much more research on language acquisition and development that the author could have found to add more credence to his hypothesis.
