Cognitive ScienceDewey (1896): “Sequences of acts are composed such that

subsequent experiences categorize and hence give meaning to what was experienced before.”

Gero (1998): “where you are when you do what you do matters”

Experimental StudiesSchön and Wiggins (1992): “interaction of making and seeing”

Suwa, Gero and Purcell (1999): “Sketches serve as a physical setting in which design thoughts are constructed on the fly in a situated way.”

Situatedness


Where you are when, matters




What you focus on matters

No unique representation of world, depends partly on your expectations
