I'm reading a book about communication styles, and it claims that "A Japanese woman who not only doesn't cry but laughs when talking about her husband's death might be misdiagnosed by a Westerner who does not know that laughter is the customary and expected Japanese way of masking emotions".
Can someone tell me how much truth there is in that? The book is from the mid 80s and written by an American so I'm unsure how much to trust it (for this specific thing).
