In "Honest Signals: How They Shape Our World" and the related publications "Understanding 'Honest Signals' in Business" and "Social Dynamics: Signals and Behavior", Alex Petland puts forth the idea that non-semantic communication (communication we do without explicitly representing thoughts using words/drawings, such as our gestures or aspects of our voice) falls into the following four types.
Types of Non-Semantic Communication
Jerky, uneven motions indicate many different thoughts indicating openness to influence. Consistent emphasis and timing indicates mental focus.
How much the social patterns of each participant match. Correlates with trust. Verbally this is measured by sub-second utterances ("Uh-huh") and exchanges built on these utterances ("OK?", "OK!", "Done?", "Yup.").
The amount one forces or cedes their social patterns to another. Could also be considered as who's driving the conversation.
4. Activity level
Describes how much energy in general is being expended in the interaction. Verbally, this can be considered by the ratio of silence to exclamations.
He then applies these four concepts to analyse various scenarios (speed dating, negotiation) and demonstrates their predictive power.
Do other theories or frameworks exist with an alternative interpretation of non-semantic communication while still having the same predictive power?
