HEAD MOVEMENT CAN BE OFF-PUTTING 

When talking, be conscious of your head and the way it can move while you are presenting. Try to avoid excessive and vigourous head movements in a forwards backwards or sideways direction. 

Pronounced head movements can occur during delivery by distracting listeners from spoken words. They can become entranced by how nodding, bobbing, and head movement occur.

Using the head to emphasise the point can be a reinforcing gesture providing it’s not carried too extreme. Head movements need to be sparing and calculated to add to what’s being spoken. Don’t allow them to become distracting. 

Quite often on television presenters  demonstrate the excessive head movement. Learn about what not to do by seeing  how it’s done and measure your response as a listener when this distraction takes place.
