Although Kamin began his career as an animal researcher, he became interested in the study of intelligence after an episode involving his students and a former colleague in 1972.
While teaching at Princeton, Kamin invited Richard Herrnstein (one of the authors of The Bell Curve) to speak to his students about one of his areas of focus, the visual world of the pigeon.
After further investigation of the history of the IQ debate, he was shocked to find that respected psychologists such as Yerkes and Brigham had put forth racial theories about IQ in the 1920s and concluded that the unsupported assumption that IQ was inherited led to unjust social policy in the 1920s.
Kamin discovered that if a rat learned something about a single stimulus (for example a flashing light) then later when the rat was trained to learn something about a compound stimulus (for example a flashing light and a buzzer/noise together) then it ignored the buzzer/noise part of the compound stimulus.
This became known as "Kamin blocking" and demonstrated the very important principle that one way that animals decide what to attend to in the environment is on the basis of what they have already learned.
Using this programme we tested Kamin blocking in 30 people diagnosed with schizophrenia and 30 healthy volunteers in collaboration with the psychiatric research group of Professor M Reveley at the Leicester General Hospital.
