Placing all information on the slide area results in an overwhelming amount of information on the slide. When the text on screen is the same as what is narrated, it creates redundancy that reduces understanding. The busy slide splits attention from the speaker’s narration. Not using the notes area ignores a critical source of information, the speaker’s voice. FIGURE 2-15 The conventional PowerPoint approach does not incorporate the dual-channels concept and instead places both visual and verbal information in the slide area.

And when you apply the new sequence to your own presentations, you’ll see how BBP taps into the powerful potential of PowerPoint that has been waiting for you all along. NOTE The Ribbon has been minimized throughout the figures in this book to make the graphics more visible. If you ever need to minimize your Ribbon, click the Customize Quick Access Toolbar button next to the Quick Access Toolbar on the upper left in the PowerPoint window, and then select Minimize The Ribbon. Trick 1: Use Slide Sorter View to Manage the Volume Open a new, blank PowerPoint presentation, and on the View tab, in the Presentation Views group, click Slide Sorter, as shown in Figure 2-2.

Research Reality 2: You Have to Address the Two Channels The next research reality, the concept of dual channels, states that people receive and process new visual and verbal information in not one, but two separate but related channels. Allan Paivio described his theory of dual coding in the 1970s, and during the same decade, Alan Baddeley and Graham Hitch described a similar two-channel structure in working memory. Today, the concept has become a widely accepted standard among researchers. In the dual-channels model, the images someone sees are processed through a visual channel, the domain of images including photographs, illustrations, charts, and graphs, as illustrated conceptually in Figure 2-13 (top).
