Multiple heads, multiple devices

Levels of mapping effectiveness
Cultural interpretation of mappings, perception of space and time (relative to time, relative to person, what does going forward/backward in time mean), analog of forward/backward to text direction.

Discrimination and the information used for it
Constraints simplifying memory

Short term memory and its strengths and weaknesses
Long term memory and its strengths, weaknesses and nature

How to aid retention and recall, but best to not require memory at all.

Learned helplessness, false self-blame, imprecise behavior and how to counter it with positive psychology and giving opportunities for quick and convenient error correction and smooth continuation of the task.

Seven Fundamental Design Principles derived from The Seven Stages of Action

Precise Behavior from Imprecise Knowledge, Knowledge in the World

Behavioral and Reflective levels of processing

Levels of processing and their relation to the Seven Stages of Action
Flow State
Storytelling
The process of assigning blame, blaming the wrong things

Cognition, the relationship between cognition and emotion, declarative and procedural memory, conscious and subconscious processing.

The Three Levels of Processing, the most basic of which is the Visceral Level.
