A new study from UCLA-University of Glasgow has found how we have stereotyped even the manner in which men and women express negative emotions - while men express theirs in the form of anger, women are expected to be sad - but never the other way round.

Researchers created videotapes of men and women throwing baseballs in such a manner as to convey a range of emotions and then and asked volunteers to make judgments about the throwers'' emotions and gender.
