> Words beginning and endings are learned too because people raising young kids are spending a great deal of time decomposing and telling them simple words. Repeating "cat", "cat", "cat" with pauses. I'm pretty sure that years ago I read in a textbook somewhere that the effect size for this kind of thing is very small relative to other "parent talk" behaviors like exaggerated intonation? (But I also wouldn't be surprised if that was just the author's take and not at all a settled matter.)
