Body language is a big clue to noticing cognitive overload. Some easy to recognize indicators include:

• Frustration
• Glazed over eyes
• Look of boredom

If you are evaluating learners in an online class, or a technical course, learners that are experiencing cognitive overload often have an increased error rate.

Another key factor for trainers is evaluating your class, do a mini audience and needs analysis as you go along. Ask yourself these questions:

• How are the learners responding to practice and group activities?
• What kinds of questions are your learners asking? Are they behind or ahead of the group?

Those learners who are experiencing cognitive overload feel overwhelmed and frustrated. Most often, they won't be the ones asking the questions because they are afraid they will ask a dumb question. Be aware of your audience at all times, and review your instructional design!

Now that you can recognize cognitive overload, let's look at some very easy strategies to avoid this situation all together.
