Regional Dialect Perception

This paper and experiment made me think about other things besides residential history that could affect dialect perception.  For instance, does gender, race and/or age also affect people's regional dialect perception?  The paper briefly discussed age, but only in so much as to say that adults are better at distinguishing between different regions because of more travel experience.  This same experiment can be done only with the listeners being all female or male, of different races, and then at different ages.  With that information you would be able to compare it to the information gathered from the first study.  I also thought it was really interesting to see which listening groups believed they sounded more similar to which groups, even if they were from the same region and the only difference was whether they were mobile or non mobile.  I also thought it was counterintuitive that the number of stimulus repetitions did not have any effect on accuracy of dialect distinction.  

To comment on an old topic,  I was recently watching Mrs. Doubtfire  and was reminded of accent discrimination in the scene when Daniel (the father) calls impersonating different potential housekeepers.  Miranda would hang up the phone in particular when he pretended to have a very strong accent from another country, and say that the position is already filled ( just like in the article we read about discrimination).
