雅思啊,我看看
i think stereotypes have a function in that a chunk of information is easily retained and follows the rules of parsimony-simplicity, which is easily computerised in the mind, in some form of memory system-if we had to remember every minute detail about every single person that we have or have not met.
and with time getting to know someone gradually brings more pieces of info to the picture so a stereotype can be either confirmed or broken. A stereotype also serves the function of having a reference point in memory to latch onto so we can understand new info.
But on the flipside i think that stereotypes taken as representative of a culture is more damaging then beneficial. For example-chinese and oriental people arent very well represented by the media in the uk- there has not been one english soap with a chinese/korean/japanese character in it. Adverts which in the last few months have consisted of stereotyped portrayals of chinese and the oriental culture. this does not show people in an accurate light-we are not all kung fu fighters who are stupid-you even had mainstream television shows mocking the fact that the japanese cannot pronounce r-what childish humour? I mean for god sake there was a whiskas advert which was very offensive too-stereotypes can often be true as they consist of stratified information that has built up over time. but they are no use for getting to know real people.
