Interesting, but a couple of points worth considering. It is more an issue of them missing alot when you speak to them Language grasp =/= communications skills. (1) Plenty of studies on body language and other forms of cognitive bias back this up. Attractive people are deemed more trustworthy etc. (2) There are huge swathes of social interactions and nuances that cultural signals. 'Westenized' children educated for example in the us or uk grasp intuitively things completely alien to their parents or to similar kids brought up in the east. Such examples of ""comprehension has noting to do with wether or no the kids have accents or their "language skills". (3) A regional welsh, working class, or a northern uk dialect is almost indecipherable to many americans. But such would not likely be a signal that this person won't be able to pick up westernized social cues.
