Presentation aids can fulfill several functions: they can serve to improve your audience’s understanding of the information you are conveying, enhance audience memory and retention of the message, add variety and interest to your speech, and enhance your credibility as a speaker. Let’s examine each of these functions.

The old saying “You never get a second chance to make a first impression” points to the fact that first impressions matter. The brain is a predictive organ in that it wants to know, based on previous experiences and patterns, what to expect next, and first impressions function to fill this need, allowing us to determine how we will proceed with an interaction after only a quick assessment of the person with whom we are interacting. Research shows that people are surprisingly good at making accurate first impressions about how an interaction will unfold and at identifying personality characteristics of people they do not know. Studies show that people are generally able to predict how another person will behave toward them based on an initial interaction. People’s accuracy and ability to predict interaction based on first impressions vary, but people with high accuracy are typically socially skilled and popular and have less loneliness, anxiety, and depression; more satisfying relationships; and more senior positions and higher salaries. So not only do first impressions matter, but having the ability to form accurate first impressions seems to correlate to many other positive characteristics.
