Contains details on his 5 extraneous principles.

Extraneous Principle 1: Coherence

This screenshot is of the main screen of the Brain Anatomy iPad app. The main menu exhibits good coherence, as it does not contain any extraneous words or pictures. All of the images for the different views have the corresponding text overlaid.

Extraneous Principle 2: Signaling

This screenshot exhibits both good and bad examples of signaling (the highlighting of key concepts). The corpus callosum section of the brain is highlighted (good), but the corresponding menu option to the left is not highlighted (bad). Ideally, both the menu item on the left, and the corresponding section of the brain would be highlighted.

Extraneous Principle 3: Redundancy

This screenshot is of the view that shows the horizontal sections of the brain. The 6 pictures to the left and right of the center image are previews, and are therefore not redundant. If there were labels on the color lines in addition to the previews, that would be considered redundant.

Extraneous Principle 4: Spatial Contiguity

This screenshot is a poor example of spatial contiguity. The list of all of the possible brain sections are listed to the left, but there is no way to tell which name corresponds to which part of the brain without tapping on each individual name. The words and images are displayed on separate parts of the screen, instead of close to each other and in a way that is more spatially intuitive

Extraneous Principle 5: Temporal Contiguity

This screenshot is another example of "the good and the bad." To the right is a good example of temporal contiguity, as the different parts of the brain are shown in different colors, that correspond to the labeled key at the bottom of the screen, and are shown simultaneously. There is, however, a bad example on the same screen. In order to highlight individual sections of the brain, you need to tap on each individual label on the left, which is a list of numbers instead of matched colors.
