Latent toxoplasmosis has been previously found to cause behavioural and personality changes in humans, which are specific for each gender. Here we tested the stress hypothesis of these gender differences based on the assumption that latent toxoplasmosis causes long-term subliminal stress. In line with this hypothesis, the gender difference will appear specifically in situations with interperson...

Healthy males completed a validated attachment style measure, received intranasal oxytocin or placebo, and privately chose between cooperation and non-cooperatio...
