stimulus predifferentiation

Stimulus predifferentiation is a concept in psychology related to how prior exposure to a situation can improve subsequent learning. It's like seeing a film about a microscope before using one; you're better prepared to learn the skills needed to operate it.1

In laboratory studies, subjects are first familiarized with a stimulus. Later, they learn new tasks involving that same stimulus. For instance, if someone practices labeling lights, they might learn faster to press switches connected to those lights. This prior exposure helps learners distinguish environmental components, potentially by making stimuli more distinct or encouraging focused observation. It's a form of learning that builds upon initial acquaintance with stimuli, aiding in the acquisition of new responses.1
