Final answer:
Both positive and negative types of contact with other people affect culture, as these interactions can lead to the exchange of ideas, beliefs, or conflicts that bring about change in a culture's practices and understandings.
Step-by-step explanation:
The types of contact with other people that affect culture are both positive and negative contacts. Cultures evolve and change through the influences of various interactions, and these contacts can be seen as exchanges of ideas, beliefs, technologies, and art forms, among other cultural elements. Both positive experiences such as friendly trade, or the exchange of ideas, and negative experiences like conflicts or colonization can significantly impact a culture by introducing new concepts or altering existing practices. For instance, a positive contact like cultural exchange programs can lead to a greater understanding and appreciation of different ways of life, whereas a negative contact such as war can lead to the adoption of certain survival strategies or technologies that alter a culture's way of living.
Cultural change is an ever-present facet of human societies, driven by both internal dynamics and external interactions with different groups. Locally, a society might experience cultural lag when old norms struggle to catch up with new technologies or social practices, impacting how people interact and perceive their world. Additionally, wide-ranging factors such as economics, religion, and geopolitics can all play roles in cultural development – whether constructive or destructive.
