Features of threatening cues and the associated context influence the perceived imminence of threat and the defensive responses evoked.

Cardia…

In academia, parenthood may be perceived as negatively affecting scientists’ commitment and dedication, especially women’s. We conducted a survey amongst Brazilian scientists and found that…
