The following article has been retracted: “Twenty-First Birthday Drinking: Extreme Drinking Episodes and White Matter Microstructural Changes in the Fornix and Corpus Callosum” by Cassandra Boness, Ozlem Korucuoglu, Jarrod Ellingson, Anne M. Merrill, Yoanna E. McDowell, Constantine J. Trela, Kenneth Sher, Thomas Piasecki, and John Kerns (Experimental and Clinical Psychopharmacology, 2020, Vol. 28, No. 5, 553–566. http://dx.doi.org/10.1037/pha0000336).
The explanation for the retraction: In preparing to use the DTI images for secondary data analysis, it was discovered that multiple participants had the wrong DTI data included for Session 1 analyses. This was due to a file transfer error that incorrectly substituted another participant’s DTI data for the correct DTI data. In correcting the error and reanalyzing the data, our findings changed in ways that were nontrivial and, thus, exceed what would be appropriate for a corrigendum.
