120 bits a day for native language acquisition

Some researchers at U. Rochester and U. Cal. Berkeley attempted to estimate how much information a child learns to acquire a native language.

To put our lower estimate in perspective, each day for 18 years a child must wake up and remember, perfectly and for the rest of their life, an amount of information equivalent to the information in this sequence:

0110100001101001011001000110010001100101
0110111001100001011000110110001101101111
0111001001100100011010010110111101101110

Even at the lower end, it suggests the presence of mechanisms in the brain that help in language acquisition. I guess a question I have is what is the threshold for there not to be one? (The upper end is almost 2,000 bits a day.)

And we are talking about every bit here being new information.  Similar to the Five Books a Day post, these are NEW bits every day.

The amounts are staggering to me. And it strikes me how impressively children learn about the world, categorize the data, and synthesize it into information. The challenge as a parent is to ensure the child gets enough exposure to acquire all this data.
