There are several parameters that may be perceived differently by people of different cultures. These may include:
High and low context cultures: Context is the most important cultural dimension and also immensely difficult to define. The idea of context in culture was an idea put forth by an anthropology by the name of Edward t Hall.
Low-context cultures assume that the individuals know very little about what they are being told, and therefore must be given a lot of background information.
High-context assume the individual is knowledgeable about the subject and has to be given very little background information.
