Associations in humans can be measured with the Implicit Association Test, a psychological test which measures the implicit (subconscious) relation between two concepts, which was created by Anthony G. Greenwald in 1995. It has been used in investigations of subconscious racial bias, gender and sexual orientation bias, consumer preferences, political preferences, personality traits, alcohol and drug use, mental health, and relationships. The test measures the associations between different ideas, such as race and crime. Reaction time is used to distinguish associations; faster reaction time is an indicator of a stronger association. A D score is used to represent the participant's mean reaction time. If the participant's mean reaction time is negative, then that individual is thought to have less implicit bias. If the participant's mean reaction time is positive, then that individual is thought to have more implicit bias. A D score for each participant is calculated by deleting trials that are greater than 10,000 milliseconds, deleting participants that respond quicker than 300 milliseconds on over 10% of trials, determining inclusive standard deviations for all trials in Stages 3 and 4 and also in Stages 6 and 7. Mean response times are determined for Stages 3, 4, 6, and 7, the mean difference between Stage 6 and Stage 3 (MeanStage6 - MeanStage3) will be computed as well as the mean difference between Stage 7 and Stage 4(MeanStage7 - MeanStage4), each difference is divided by its associated inclusive standard deviation, and the D score is equivalent to the average of the two resulting ratios.
