Affordances : Patterns We Can Use

I have been studying Soc Psych and am beginning to have a bit of an idea. What I’ve read so far is Soc Attitude and Soc Perception. In perception one thing is standing out: patterns. I mean patterns in the most general sense of the word. Soc Interaction is based on patterns and one theory for non-verbal patterns calls them “affordances“.  A theory on impressions calls them “traits”.  They are both the same thing, perceptual patterns we can use.

But I like the word affordance because in the theory related to it utility is mentioned.

I have seen the word affordance used in design.  Simply put a design affordances are “patterns physical or virtual we can use.”

That makes my more general definition, affordances, “patterns we can use”.

Affordance is discussed in Wikipedia as well.
