Implicit Association Test

Background and Definition of the Implicit Association Test (IAT)

Psychologists have long suspected the existence of thoughts and feelings that are not accessible by simply asking a person to report them. It may be that people are unwilling to report what they think and feel. Or, even more likely, people may not be aware of everything that they think and feel. Beginning in the 1980s, efficient alternatives to self-report measures were invented to study implicit or unconscious forms of thoughts and feelings. One such measure is the Implicit Association Test (IAT).

The IAT requires respondents to rapidly sort items from four different categories into groups. For example, imagine sorting a deck of playing cards - with red hearts, red diamonds, black clubs, and black spades - two times. For the first time, all the hearts and diamonds are sorted into one pile and all the clubs and spades are sorted into a second pile. This would be quite easy to do because the suits are being sorted by a common perceptual feature - color. Now imagine doing the same task but this time sorting clubs and hearts into one pile and diamonds and spades into the other. This would probably be harder and take longer to complete because clubs and hearts are not as related to each other as are hearts and diamonds. The simple idea is that things that are associated by some feature are easier to put together than things that are not associated.

Now translate the idea of sorting cards by their suit to sorting items by their social categories. A gender IAT, for example, would provide a measure of the relative strength with which female and male are associated with family versus career concepts. Like sorting cards by their suit, sorting female with family ...
