1. How does the speaker attract the attention of the listeners? She begins by offering to give the public free advice regarding daily life. In close succession, she chooses to engage the audience in a small exercise that seems to gently explain what the audience expects from her speech. In the exercise, she highlights some key things the audience could do right now and states that these will be covered later in the talk. Additionally, she introduces the topic of body language in a humorous way that completely engages the audience.2. How does the speaker build credibility? The speaker lightly mentions the fact that science, particularly the social sciences, has contributed greatly 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 area of ​​prejudice extensively. Additionally, she rounds out her credibility by claiming that she also teaches at a competitive business school.3. What is the speaker's purpose?The overall purpose of the speaker who appears is to explain how body language or nonverbal behavior influences communication and interactions: how we perceive others and how they perceive us. Additionally, she breaks it down to make it clear that non-verbal expressions also impact how powerful or weak we feel.4. What types of support does the speaker use? The speaker uses examples extensively to convey her message. It mainly provides them in the form of photos, or even videos as in the case of the handshake. She also uses testimonials to show how body language helps judge others. Additionally, she also makes expansive use of the medium of paper to look and feel confident. People tend to judge us based on our own body language. So if we adopt a posture that shows weakness, then that is what others understand. But this can be reversed if we learn to use just a few minutes of our time, as the speaker suggests, to properly constitute our mindset to adapt to a particular situation, which will undoubtedly lead to very pleasant. The fact that science offers evidence of the same thing described in the speech also serves to solidify my agreement with this suggestion. It is clear that indeed, the way we communicate non-verbally has a significant influence on how we feel in any given situation. Therefore, as the speaker said, we can change the way we perceive ourselves by making simple changes to our life, such as occasionally trying the power pose..
