I like how Leland explained and provided examples of learning principles the presentors presented in there in presentation. An example is the signalling principle and Dr. Bavelier uses this by using underlines and arrows. Another concept i enjoyed that was covered was the Dual coding theory that Leland points out the presentor Dr.Bavelier utilizes by making mental images that connects to the lesson she is teaching.

I wonder if you Leland could of used some images in your post to connect the multimedia principles shown in the presentation that you outlined to help better prove the point they are present.

Overall really great post that connects multiple multimedia principles shown in the Ted talk! Great job Leland!
