This confirms that unborn babies can hear their environment well enough to perceive language, and that culture and mindset are already being moulded before birth.

The study doesn't investigate the case of babies born in bilingual environment, or the influence of foreign-language TV exposure (e.g. pregnant mothers watching original films or series in English every day).
