We Remember More Than You Think

It always leads to an interesting discussion when people talk about memories – their earliest ones, are memories accurate, or why do we forget so much. A new wrench in the worksstudy proved that we store more memories than we realize. This was the study:

Group A – Chinese girls adopted at infancy by French Canadian parents. These girls never spoke Chinese again and had no recall of the language.

Group B – Chinese girls adopted at infancy by French Canadian parents and are bi-lingual, speaking both French and Chinese.

Group A and B were compared with a French speaking non-Chinese control group, C. All girls underwent fMRIs scans while listening to tapes of Chinese language being spoken. The brains of A and B lit up in identical ways. The area of the left superior temporal gyrus (sound processing) was activated. Group C’s brain lit up on the other side. The author’s conclude, “Early acquired information is maintained in the brain” and early experiences unconsciously influence the neural processes for hers, maybe indefinitely.
