How were the young chimpanzees treated at the first laboratory?

At the first laboratory, young chimpanzees were often subjected to harsh and inhumane treatment. They were kept in isolated conditions, deprived of social interaction, and used in experiments that caused physical and psychological distress. This treatment was driven by a lack of understanding of their emotional and social needs, leading to significant suffering among the animals. Over time, such practices prompted ethical reconsiderations regarding the treatment of primates in research settings.
