สรุป	Dialectometry is the quantitative measurement of how linguistically different dialect sites are from one another, aggregated across many features at once. Pioneered by Jean Séguy in the early 1970s and developed by Hans Goebl in Salzburg and John Nerbonne in Groningen, it takes the rich response data of traditional dialect atlases and computes, for every pair of survey sites, a single number summarizing their overall linguistic distance. These pairwise distances are then clustered and mapped, turning a sprawling atlas of individual features into an aggregate picture of dialect landscapes, continua, and boundaries that no single feature could reveal.	Perceptual dialectology studies what ordinary, non-linguist speakers believe about language variation: where they think different dialects are spoken, what those dialects sound like, and how correct, pleasant, or different they judge them to be. Developed in its modern form by Dennis R. Preston in the 1980s, it is a branch of folk linguistics that treats lay perceptions as data in their own right rather than as errors to be corrected. Through draw-a-map tasks, dialect ranking, and identification exercises, it reveals the mental maps and social evaluations that shape how people experience the linguistic landscape around them.
