I. e. letter a is composed of /, \, and . & wiesel, 1962) humans are wired to detect simple features. Psychological support (gibson, 1960s) more likely to make mistakes if letters are similar (p vs. r) than if letters are different (g vs. l) Combines 3-d aspects of marr"s theory with feature aspects (biederman, 1987) Geons = geometrical ions; representations of 3-d shapes.

Only works for simple stimuli (i. e. fingerprints, barcodes, etc. ) Only works for exact matches (no sloppy matches (i. e. penguin/chicken does not fit. Participants only recognized component deletions, not segment deletions.
