Data original authors contacted for original materials: 19/10/2012. We originally sought to replicate part of a 1996 Psychological Science paper by Buss and colleagues and contacted the lead author for these materials. Given that the 1996 paper included a physiological measure, and the 1999 and 2004 paper included an updated version of the questionnaires used in 1996, we chose to replicate the 1999 and 2004 papers. Buss also attended us that the later questionnaire was more accurate.
