The rat's speed-of-locomotion gradient in the approach to food
Hull's 1934 paper in the Journal of Comparative Psychology reports rats running a straight runway fitted with electrical contacts so that each section could be timed. As the 2006 review by Kivetz and colleagues describes it, the rats ran faster the closer they came to the food. No figure from the study is used in the article.
