New research, attempting to throw light upon how male and female brains differ, has found that timing is everything．American Vanderbilt University researchers Stephen Camarata and Richard Woodcock discovered that females have a significant advantage over males in timed tests and tasks．The study involved more than 8,000 males and females ranging in age from 2 to 90 from across the US．

　　“We found hardly any differences in overall intelligence．But we discovered that females performed better than men in time limited situations,”Camarata said,“It is very important for teachers to understand this difference in males and females when it comes to assigning work and tests．”

　　Many males can do a better job without strict time limits, added Camarata．

　　“Consider that many classroom activities, including testing, are directly or indirectly related to processing speed,”the researchers wrote in their report．“The higher performance in females may contribute to a classroom culture that favors females, not because of teacher bias(偏见)but because of inherent(与生俱来的)differences in gender processing speeds．”

　　The researchers found that males scored lower than females in all age groups in tests measuring processing speed．However, the study also found that males consistently outperformed females in some language abilities, such as identifying objects and knowing antonyms(反义词)and synonyms(同义词)．The research contradicts the popular belief that girls develop all communication skills earlier than boys．

　　The researchers found no significant overall intelligence differences between males and females in any age groups．

　　“We believe there are fundamental differences in how male and female brains end up getting organized,”Camarata said,“Our next studies will give us some insight into where these processing differences are occurring．”
