Babies, memory, categorising and 'chunking'

Interesting research just published (mentioned in New Scientist): "Babies also remember only three things at a time, and they get past the limitation by categorising.". The 'alo' refers to the general human capacity. Which indicates that our memory is not about dloping brains but about developing thinking tools and skills. Another blow to genius. Needless to say, this fits with the insights about the importance of 'chunking' in learning and I'm adding it to my ongoing theological reflection relating to the importnace of 'naming' for human culture and development (see 'homo loquens' tag).
