Effects of prenatal stress on lever-press acquisition with delayed reinforcement in male and female rats.

abstract：:Humans respond to an infant crying with an increase in cortisol level and heightened alertness, a response interpreted as emotional contagion, a primitive form of empathy. Previous results are mixed when examining whether dogs might respond similarly to human distress. We examined whether domestic dogs, which have a l...

However, in many temperate species, it is now recognized that both males and females produce song.
