Extreme variation in social experience has even been shown to overwhelm hormonal effects on the development of these behaviours [Thornton et al., 2009]. This study will document the developmental timing of sex differences in social...

Lateral views of the walking of 5 monkeys were taken by a video-camera and the timing of touchdown and liftoff was recorded. The total number...

It was found that there are many common features in the process of infant socialization in species of the genus Mαcαcα: mothers play an important and active role...
