The Implicit Association Test (IAT) is a psychological tool designed to measure the strength of automatic associations between concepts. It assesses how quickly individuals can pair different words or images, revealing underlying biases that may not be consciously acknowledged. The test often focuses on associations related to race, gender, or other social categories. Participants respond to stimuli by categorizing them as quickly as possible, which helps researchers understand implicit attitudes. The IAT is widely used in social psychology to explore topics like prejudice, stereotypes, and implicit bias, providing insights into how these factors influence behavior and decision-making.
