Non Verbal Cues Signal and Effect.

Our non verbal cues are intimately connected with how we feel and how we perceive ourselves.
Non Verbal cuer
Conditioning is a process whereby automatic feelings and actions are brought on by the presence of particular cues. We become conditioned as a sensory stimulus is repeatedly paired with a feeling, such as an enraged parent with a slap, leading to any anger evoking the emotional fear and hurt.
As we grow used to being with other people, we unconsciously learn to read their non verbal cues particularly as they trigger emotions and memories that let us figure out what will happen next. And we then repeatedly react before the event occurs, for example flinching at an angry voice. Positive cues happen too, such as when we feel good when others smile.
Using itr
Watch for correlations between a person's body position or movement and their thoughts. When they have a negative attitude, get them to change position, for example getting them to sit if they are standing.
Non Verbal cues as evidencer
When we are aroused, we look to our surroundings to find explanation. If you are held hostage with an attractive other person, you may conclude you are fascinated to the person rather than being frightened of the scenario.
In research, Briñol, Petty, and Wagner (2009) felt more confident when reading messages with their back straight and chest out than when they were slouched forward with back curved in a doubt posture.
Using itr
In changing minds, you can help this by arousing the other person (for example by getting them to talk about something that makes them happy) and then presenting a cue (such as your product or idea).
You can also become more confident and powerful by adopting a confident and powerful posture.
Non Verbal Cues as persuasionr
Research has shown that non verbal communication easily acts to persuade others, such as where nodding increased a preference for a pen whilst a shaking head decreased preference for the pen (Tom et al. 1991).
Using itr
We also persuade ourselves by the non verbal communication we are using. For example Strack, Martin, and Stepper (1988) found that subjects who were made to use smile muscles (pen between teeth) enjoyed cartoons more than those who were prevented from smiling (pen between lips).
For persuasion, an implication of this is that if you can get a person to change their body they will also change their mind. A typical example is giving a person who is displaying closed non verbal communication something to hold or getting them to walk, thus forcing them to open their stance.
