Target of replication. The finding we are attempting to reproduce is that women with a partner will prefer attached men during the less fertile days of their cycle and single men during the more fertile days of their cycle, while single women will show no such preference.
A priori replication criteria. A successful replication would show a statistically significant three-way interaction with man's availability, participant's conception risk, and participant's partnership status such that man’s availability and participant’s conception risk interact significantly for partnered women but not for unpartnered ones. In particular, this interaction should show that women with a partner will prefer attached men during the less fertile days of their cycle and single men during the more fertile days of their cycle.
Materials, Data, and Report. Study materials can be found in the Materials component of this project. Pre-planned cleaning and analysis scripts (including a priori power analyses) can be found in the Cleaning and Analysis node. The raw and cleaned data will be posted in the Dataset node once data collection is complete. The full replication report and other materials will appear in the files section of this node.
Conclusions. Data collection is currently underway so no conclusions can be drawn at this time.
