The Hofstede Cultural Dimensions are a theory for cross-cultural communication evaluation, developed by Geert Hofstede. These dimensions regard anthropological problem areas that different national societies handle differently like i.e. culture on the values of its members and the relationshipt towards behavior.
Albert Mehrabian developed a communication model, in which he demonstrated that only 7% of what we communicate consists of the literal content of the message. The use of one’s voice, such as tone, intonation and volume, take up 38% and as much as 55% of communication consists of body language. This 7 – 38 – 55 -model is still much used today.
