Spoiled Princess,
it is true that New Jerseyans and New Englanders speak more like people from England that Americans.
When a linguistics professor of mine once mentioned that a point from the text, that Brittish accents have more vowel sounds than American accents do, the entire class was confused. She had to gloss that with a the statment that, well, in New Jersey, there are actually more.
This test, interestingly is based on vowel pronunciation - not inflection, vocabulary, or rhotic/non-rhotic r's.
Can you tell me where in England the people who speak with the rhotic accents are from? That is to say, they alternate between voiced, and silent R's the way most of us do in New York and New Jersey, not always the silent R's (non-rhotic) of London and most of the UK? They sound almost like us. I often mistake them for Americans, although Americans from other states know right away they are Brittish! I am told that this group of Englishmen gave us the basis our accent.
(This is interesting and confusing though, because non-rhotic (silent R's)
accents are in general receeding in the USA. In the South, they are rapidly receeding, even though the southerners by no means are loosing their distinctive twang otherwise. The non-rhotic accents of New York and New Jersey are sometime associated with the older generation or the working classes. On the other hand the rhotic accents of England are the ones that are receeding.)
