Two artifacts found in the same stratigraphic layer are assumed to be of similar age due to the?
saw5 [17]

Two artifacts found in the same stratigraphic layer are assumed to be of similar age due to the Law of Association.

The principal laws of the association are contiguity, repetition, attention, pleasure-pain, and similarity. The fundamental legal guidelines were formulated with the aid of Aristotle in about 300 B.C. and by way of John Locke in the 17th century.

Aristotle counted 4 laws of association when he examined the techniques of remembrance and recall: The law of contiguity things or events that occur near each other in space or time tend to get related collectively in the thoughts. Laws of the association are the principle underlying the connections inside the memory between certain ideas, feelings, or behaviors.

Aristotle's analysis of gaining knowledge of memory consists of four laws of association: the legal guidelines of continuity, assessment, frequency, and similarity. Accounting for learning and reminiscence in phrases of such legal guidelines of affiliation is referred to as institutions.
