Mammals priming pheromones

Signaling pheromones are animal-produced, interindividual chemicals that modulate behavior in conspecifics. Like visual and auditory signals, they have comparatively rapid effects exchange of signals takes seconds or minutes. (Priming pheromones [Ch. 8], hy comparison, trigger slower endocrine or developmental processes.) The pheromone concept, originally based on insects (Karlson and Luscher, 1959), has been debated for vertebrates, notably mammals (e.g. Beauchamp etal., 1976 Johnston, 2001). Often it is better to use the term body odors to avoid particular assumptions. Now the term pheromones is widely used for vertebrates, without any particularly narrow definition implied.
