Implicit Association Test

The Implicit Association Test (IAT) is an experimental method within social psychology designed to measure the strength of automatic association between mental representations of objects (concepts) in memory. The IAT requires the rapid categorization of various stimulus objects, such that easier pairings (and faster responses) are interpreted as being more strongly associated in memory than more difficult pairings (slower responses).

The IAT is a tool in the development of theories of implicit social cognition, a body of results that suggest that many cognitive processes that affect behavior are unconscious in nature and are inaccessible to observation by the actor. These implicit processes affect perception, influence behavior, and color interpretation of past events. The IAT has been profiled in major media outlets (e.g. in the "Washington Post" [ cite news | last = Vedantam | first = Shankar | title = See No Bias | publisher = Washington Post | date = 2005-01-23 | url = http://www.washingtonpost.com/wp-dyn/articles/A27067-2005Jan21.html | accessdate = 2008-10-10 ] ) and in the popular book "Blink," where it was suggested that one could score better on the implicit racism test by visualizing respected black leaders such as Nelson Mandela. The most prominent implicit association test is one that measures bias on race. Other popular tests look at gender and age bias.

The IAT was introduced in 1998 by Anthony Greenwald, Debbie McGhee, and Jordan Schwartz. Project Implicit, a research and educational outreach program that allows individuals to take the test over the web, is run by social psychologists Greenwald, Mahzarin Banaji, and Brian Nosek.

The IAT has also been used in clinical psychology research. Recent work led by Bethany Teachman at the University of Virginia has shown that implicit associations may be maintaining or causal factors in the development of anxiety disorders.

A recent meta-analysis has suggested that the IAT is a better predictor of some forms of behavior (e.g. discrimination) than traditional 'explicit' self-report methods, [ cite paper | last = Poehlman | first = T.

The IAT has been used to measure attitudes toward objects in the environment, self-esteem, self-identity, and stereotypes. In applied settings, the IAT has been used in marketing and industrial psychology.

Variations of the IAT include the Go/No-go Association Test (GNAT) and the Brief-IAT.

Criticism and controversy

The IAT has engendered some controversy (e.g. in the [http://pqasb.pqarchiver.com/wsj/access/934366591.html?dids=934366591:934366591&FMT=ABS&FMTS=ABS:FT&date=Dec+1%2C+2005&author=Amy+Wax+and+Philip+E.+Tetlock&type=8_90&desc=%27We+Are+All+Racists+At+Heart%27 Wall Street Journal] ; [http://www.sciencenews.org/articles/20060422/bob9.asp Science News Article] ). More specifically, it has been interpreted as assessing familiarity [cite web | title = Dr. Anthony Greenwald / IAT Materials | last = Greenwald | first = Anthony | url = http://faculty.washington.edu/agg/iat_validity.htm#famil | accessdate = 2008-10-11 ] , perceptual salience asymmetries [cite journal | last = Rothermund | first = Klaus | coauthors = Wentura, Dirk | title = Underlying Processes in the Implicit Association Test: Dissociating Salience From Associations | format = PDF | url = http://faculty.washington.edu/agg/IATmaterials/PDFs/R&W.JEPG(2004).pdf | journal = Journal of Experimental Psychology: General | volume = 133 | issue = 2 | pages = 139-165 | date = 2004 | publisher = American Psychological Association ] , or mere cultural knowledge regardless of personal endorsement of that knowledge [ cite journal | last = Karpinski | first = Andrew | coauthors = Hilton, James L. | title = Attitudes and the Implicit Association Test | format = PDF | url = http://faculty.washington.edu/agg/IATmaterials/PDFs/Karpinski&Hilton.JPSP(2001).pdf | journal = Journal of Personality and Social Psychology | volume = 81 | issue = 5 | pages = 774-778 | date = 2001 | publisher = American Psychological Association ] . A more recent critique argued that there is a lack of empirical research justifying the diagnostic statements that are given to the lay public [ cite journal | last = Blanton | first = Hart | coauthors = Jaccard, James | title = Arbitrary Metrics in Psychology | format = PDF | url = http://psychology.tamu.edu/Faculty/blanton/bj.2006.arbitrary.pdf | journal = American Psychologist | volume = 61 | issue = 1 | pages = 27-41 | date = January 2006 | publisher = American Psychological Association ] . Proponents of the IAT have responded to these charges [cite web | title = Dr. Anthony Greenwald / IAT Materials | last = Greenwald | first = Anthony | url = http://faculty.washington.edu/agg/iat_validity.htm#famil | accessdate = 2008-10-11 ] , but the debate continues.
