Wiki Version:
This project contains additional materials and information related to: Schultheiss, O. C., Wirth, M. M., & Stanton, S. J. (2004). Effects of affiliation and power motivation arousal on salivary progesterone and testosterone. Hormones and Behavior, 46(5), 592-599. I have added the main data file (SYSTAT and SPSS), syntax (SYSTAT, but can be viewed in any text editor), and output on Oct 23 2019. Although the data file contains more data than what was reported in the paper (i.e., it also includes data from a dot-probe task), the study was originally designed to specifically test whether affiliation arousal, but not other types of arousal, would increase participants' salivary progesterone. The hypothesis was based on earlier correlational findings by Schultheiss, Dargel & Rohde (2003, Hormones & Behavior). Had the option existed, we would have preregistered this hypothesis, because it was the one we set out to test in the first place. Please check for further updates.
