Ted Nettelbeck was interviewed by David Lubinski at the 2008 meeting in Decatur, Georgia.

Ted Nettelbeck is an emeritus professor of psychology at the University of Adelaide in Australia, where he spent his career studying human intelligence and individual differences in cognition.

He is best known for his work on inspection time, a simple perceptual task that measures how quickly a person can take in visual information. Beginning with his research in the 1970s, Nettelbeck helped establish that this basic measure of processing speed is reliably related to psychometric intelligence, giving researchers a window into the elementary cognitive processes that underlie IQ. His studies have ranged across the lifespan and across the full range of ability, from children and university students to older adults and people with intellectual disability.
