A developmental psychologist begins with an established theory of cognitive development, which posits that children under the age of seven cannot understand the concept of conservation. From this theory, the psychologist formulates a specific, testable hypothesis that a sample of five-year-old children will fail a conservation of liquid task, and then conducts an experiment to collect empirical evidence to test this prediction.

Which of the following terms describes this scientific process of starting with a theory and drawing a specific, testable hypothesis from it?
