1. How does the speaker attract the attention of the listeners? Start by offering to give the audience free advice on everyday life. In quick succession, he chooses to involve the audience in a small exercise that seems to explain in a moderate way what the audience should expect from his speech. In the exercise, highlight some essential things the audience could do right now and say that these will be presented later in the speech. Furthermore, it introduces the topic of body language in a fun way while fully engaging the audience.2. How does the speaker build her credibility? The speaker lightly mentions that science, particularly the social sciences, has contributed much to understanding the effects of body language on judgments. She then goes on to mention that she is actually a social psychologist and has studied the field of prejudice extensively. Furthermore, he complements his credibility by stating that he also teaches at a competitive business school.3. What is the speaker's purpose? The overall purpose of the speaker meeting is to explain how body language or nonverbal behavior influences communication and interactions: how we see other people and how they see us. It also breaks it down to make it clear that even nonverbal expressions have an impact on how powerful or weak we feel. What types of media does the speaker use? The speaker uses examples extensively in conveying his message. It mainly provides them in the form of images and even videos as in the case of handshake. He also uses testimony to show how body language enables our judgment of others. Furthermore, she extensively uses the use… of the medium of paper… calmness to appear and feel confident. People tend to judge us based on our individual body language. So, if we assume a posture that indicates weakness, then this is what is understood by others. But this can be reversed, if we learn to use just a few minutes of our time, just as the speaker suggests, to properly train our mindset to adapt to a particular situation, which, without a doubt, will result in very pleasant results. The fact that science offers evidence for what is illustrated in the speech also serves to solidify my agreement with this suggestion. It's clear that, in fact, how we communicate nonverbally has a significant impact on how we feel about ourselves in a given situation. Therefore, just as the speaker stated, we can change the way we see ourselves by adopting simple changes in our lives, such as occasionally trying the power pose.
