What do attention, affordance, salience, and valence have to do with meaning, and what is the architecture of encounter?

I’m still trying to figure out how to simplify these concepts. How am I doing?

• 0:00 Introduction and Encounter
• 0:52 Attention
• 1:53 What is Affordance?
• 3:13 What is Salience?
• 4:12 Example: Salience Connexion and Context (My ex-wife)
• 4:44 What is Valence?
• 5:38 What is Meaning?
• 6:23 Example: Southern Hospitality (Salience and Meaning)

Short and sweet.
