Answer:
Erica is suffering from <u>situational anxiety.</u>
<u />
Explanation:
Situational anxiety is different from Generalized Anxiety Disorder, which is a continuous state of worrying that's independent from the situation. Situational anxiety is caused by new elements in a situation, or completely new situations. Those changes cause the person to temporarily lose their ability to stay calm. In Erica's case, one element has changed when compared to previous situations. Even though she is used to giving presentations, she is not used to giving them to her co-workers. The new element is what is making her nervous about it. Maybe she fears being judged by her peers more harshly than by her students, for instance.
Answer:
Visual aids can increase the audience's interest and understanding on a topic.
Explanation:
When explaining a complex or long concept to an audience, the speaker has to avoid information overload so as not to lose the audience's attention, which is usually short-spanned. Visual aids such as infographics can help summarize the information, exemplify the concepts through images, make it more memorable and simple to understand, etc.
The reason why people can process information better through images is that, according to studies (such as the study <em>Functional representation of vision within the mind: A visual consciousness model based in 3D default space
</em> by RavinderJeratha, Molly W.Crawforda and Vernon A.Barnesb), between 50-80% of the human brain is used for some sort of visual processing.
