If you have decided to use any visual aids in your presenta tion (see Chapter 7) or if you will be using a microphone, then the position from which you speak will probably be deter mined. Avoid the use of a lectern if possible. A lectern presents a psychological barrier between the speaker and the audience and makes the speaker’s task of persuasion more difficult. A lectern can become a leaning post for the speaker who gradually progresses from resting his hands, then elbows on the welcome support, to posing like the Hunchback of Notre Dame. It is much more effective to stand so that the audience can get a full-length view of you.
