Computer-Based Assessment of Implicit Attitudes

Recently, computers are being used extensively in psychological assessment. The most popular measure implicit attitude is the Implicit Association Test "IAT" [2]. According to Aberson and Beeney [3], although the IAT has been applied broadly, little is known about the psychometric properties of the measure. Four different experiments were conducted with four different samples to investigate the temporal reliability of IAT. Also students' opinion (trust) about the validity and reliability of the test was measured. The results showed that while there are numerous reports of moderate validity of the test, its reliability as measured in this study, particularly for the first time users, is relatively low. Familiarity with similar tests, however, improves its reliability.
