Snow + rocks and a further note on Gestalt theory
In the preceding post upon Gestalt Theory I warned photographers about the low ROI in reading tomes about cognitive psychology as a way to improve their own picture making.
The main reason is that the theory is based on phenomena which partly pertain to culture and partly to evolution/selection (nature). As an example consider that linear perspective is a cultural artifact as well described by Erwin Panofsky in "Perspective as Symbolic Form". This is an important question to all those involved in figurative arts. Cultural rules can be subverted (to a certain degree) while "natural" rules can be used. Other cognitive psychology schools, aware of this duality, approached the problem from other point of view as in the case of developmental psychology from Jean Piaget. More or less the separation of the two planes has been the object of most cognitive psychology till today.
