The Implicit Association Test (IAT) is a popular social psychology tool that assesses how closely people’s brains link concepts. A 10-minute computer-based measure, the IAT requires test-takers to rapidly pair words or pictures from two target conditions (e.g., male and female) with an attribute (e.g., “kind”) such that faster responses are interpreted as more strongly associated in memory than slower responses. These unknown cognitive connections may lead to implicit bias, which may influence subtle forms of discrimination. There is a desire to apply the IAT in a research framework to better understand people’s implicit biases against those who stutter. This design uses the Java’s Swing Graphic User Interface through a JApplet, which allows the Stuttering IAT to be accessed over the internet and capable of collecting and storing data. While the primary purpose is the large-scale collection of data for research purposes, the test also provides users with an estimated degree of personal preference [no, slight, moderate, or extreme] for either people who stutter or people who do not stutter.
