You have to respect the
limits of working memory

Too often we assume the “pipeline” metaphor for communication
Effective Communication with PowerPoint… Really? Working Memory

In reality, the “pipeline” metaphor is flawed.

The mind does not process a “pipeline” of information.

We need a new metaphor for communication.

The “eye of the needle” metaphor reflects current research.

You have to address the two
channels
![Page 23: There are three “Research Realities” that must be addressed](https://reader038.vdocument.in/reader038/viewer/2022103022/56649cc55503460f9498e92f/html5/thumbnails/23.jpg)
Effective Communication with PowerPoint… Really? Dual Channels
We process on two separate but related channels.
Visual Channel
Audio Channel

Effective Communication with PowerPoint… Really? Dual Channels
When someone speaks, you process the verbal information at one speed. When the speaker also displays the text of the speech, you process the information at a different speed – your mind first takes in the text visually and then verbalizes it for processing in the verbal channel. Because the same information is arriving through the same channel at different speeds, working memory has to split its efforts and reconcile the differences.

Effective Communication with PowerPoint… Really? Dual Channels
Crossing channels overloads the audience’s working memory.

You have to guide attention.
