“Experimental psychology” might be a bigger field than you imagine. It includes tons of work characterizing sensory perception. These studies tend to replicate pretty well and they have a pretty broad range of real-world applications: psychoacoustic models for audio compression, principles like pop-out and serial/parallel search that inform user interfaces, color reproduction. In fact, psychophysical experiments pinned down the properties of cone cells over a hundred years before they were directly measured. Psychometrics, the study of test/assessment design, also shows up all over the place: education, obviously, but also marketing and other forms of evaluation.
