WHAT'S NEW

  • 30 Jul 08: Revised version of submitted ms. reporting the Brief Implicit Association Test (on Unpublished Mss. page)

  • 9 Jun 08: Some new content on the IAT validity page.

  • 30 Mar 08: A pre-final draft of the in-press meta-analysis of predictive validity of the IAT is downloadable here (also on page with downloadable unpublished papers, see menu in PUBLICATIONS at left).  The final version will be about 25% larger in size (number of studies).  This is because of our efforts to locate additional papers that we could confirm as having been available in some published or unpublished form before the cutoff date of 1 Feb 07.  All numerical results will therefore certainly change, and some conclusions will be affected in at least minor ways.  It will be perhaps another month before all analyses are completed and incorporated into a final draft.

  • 13 Feb – 13 Mar 08: Reverse Bradley Effect discovered. The Democratic primaries have been most interesting, in part for the extent to which pre-election polls have been off grossly beyond their margins of error in predicting the gap between Clinton and Obama.  Over-prediction of a Black candidate is known as the Bradley Effect, after the incorrect polling prediction in 1982 that the Black mayor of Los Angeles, Tom Bradley, would comfortably win the 1982 California governship (he narrowly lost).  This year's Democratic primaries included states in which Bradley Effects occurred, but also ones in which the reverse occurred, with the difference apparently being related to varying percentages of Blacks in the states' populations.  Click here for an up-to-date graph of these surprising poll-vote discrepancies.

  • 29 Dec 07: Update of SPSS syntax for computing IAT measures using the D scoring algorithm introducted in 2003.  The update corrected some minor errors and includes some simplified description of the D measure in a small pdf file.  I regret having waited this long to make the D measure computations more accessible.  Alas, it's still not so easy.

  • 8 Sep 07: Minor updates on the IAT page: (a) fixed an error of an important file being missing from the downloadable Generic IAT zipfile on the IAT software page and (b) added some new links and updated a few old ones on the IAT validity page.

  • 26 Aug 07: Update of SPSS syntax for computing IAT D measure.  This can be found at the software link under IAT at left.  The update provides some new summary material and fixes a minor error in computing error-penalty versions of the D measure.  Thanks to Klaske Glashouwer of University of Groningen for bringing this to my attention.

  • 24 Aug 07: After exhausting reprints of a somewhat quirky 1982 chapter, titled "Is anyone in charge? Personalysis versus the principle of personal unity", I scanned and posted an electronic copy.  The chapter opposes the naive conception of the person as a unitary entity.  It can be found on both the "by date" and "by topic" (topic: self) links under "Publications", at the left.

  • 6 May 07: New items on the page with unpublished material (see PUBLICATIONS link at left).  Two of these have to do with recent inventions of variations of the IAT method — the Brief IAT and the Multifactor IAT (perhaps eventually to be called "Multidimensional IAT").  I expect that the Brief IAT will gradually replace many research uses of the standard IAT.

  • 28 Dec 06: Link to a downloadable PsyScope script and associated SPSS syntax for a self-esteem IAT, contributed by Jennifer Borton and Mark Oakes of Hamilton College — See IAT link at left.

  • 28 Dec 05: As recently advertised, there is major new content available via the IAT submenu (at left). Follow the link to the new IAT validity issues topic. This new page provides an annotated bibliography for recent and continuing debates on 14 topics related to construct validity, internal validity, and statistical conclusion validity of IAT measures. Approximately 50 downloads of various authors' works can be linked to or downloaded from this page.

    If you have problems accessing any of the material on this site, Please contact me. I would like to make this page broadly accessible, which means not only accommodating diverse browsers, but also accommodating diverse visitors.

    The downloadable material consists of .pdf or .zip files. To read downloaded pdf files you will need Acrobat Reader. To extract from downloaded zip (compressed) files you will need a file-decompression utility such as WinZip (now included in most operating systems).

    I am asked about the Chinese symbol at the left.  It was given to me (as a stamp) by graduate students at East China Normal University in Shanghai, when I visited there in May, 2002.  They translated it as "three clear", referring to clarity in pronunciation, expression, and thought.  They explained that they found those qualities in the presentations I gave (in English) during that visit. (Yes, of course I was pleased!)
