There are two major hypotheses concerning the developmental trends of processing speeds. These hypotheses explore both local and global trends. The study presented here investigates the effects of people's different knowledge on the speed with which they are able to process information. The participants in this study are gifted children aged 9, 11, and 13 years. A total of 94 of the participants were members of gifted programs, whereas the other 93 children received standard education. They were required to finish two information-processing tasks: a Choice Reaction Time task and an Abstract Matching task. The results show that the reaction time of gifted children who received accelerated education in gifted programs was significantly faster than that of the children who received standard education at every age. These results seem to imply that the educational atmosphere in which a child is placed plays a significant role in the development of gifted children's speed of information processing
