A new study suggests that intelligence is more about what the brain chooses to ignore than simply its ability to process information rapidly.
The research, which was published in the journal Current Biology, suggests new ways of testing intelligence that may be less biased by cultural knowledge— as many have claimed other IQ tests are. It may also help to explain the profound intellectual talents of some autistic people. “It’s a really interesting potential new paradigm,” says Scott Barry Kaufman, adjunct assistant professor of psychology at New York University, who was not associated with the research.
Scientists led by Duje Tadin, assistant professor of brain and cognitive sciences at the University of Rochester, studied 67 people in two similar experiments. Before beginning, all participants took IQ tests: the first twelve took short versions, the rest sat for the full battery of testing. Then they watched videos of both small and large objects that moved, very slightly, either to the right or to the left of a screen and tried to identify the direction of motion.
