prescisive abstraction
Prescisive abstraction or prescision, variously spelled as precisive abstraction and prescission, is a formal operation that marks, selects, or singles out one feature of a concrete experience to the disregard of others.
The above definition derives from one given by Charles Sanders Peirce (CP 4.235) in the context of distinguishing two kinds of abstraction, the other being hypostatic abstraction.
