This is an example of negative reinforcement.
Her mother scolded her every time Jane bit her nails - so Jane learned that every time she bites her nails, she is going to be scolded sternly by her mother. In order to avoid that, she stopped biting her nails, and thus the reinforcement was successful.
The answer is relative. To simplify, the core anthropological concept is based on the idea that people construct their version of reality in relation to the particular context in which the culture has existed. The cultural beliefs, values, and behaviors are relative to the circumstances in which they are constructed. The cross-cultural understanding means determining the relations that lead to specific assemblies. In addition, the cultural anthropology is a division of anthropology that is concentrated on the study of cultural variation between humans. It is in contrast to social anthropology in which distinguishes cultural variation as a subdivision of the anthropological constant.
