Satiation experiments in rats have revealed that BSR does not produce satiety. The effects of expected satiety and expected satiation appear to extend beyond meal planning. As with primary reinforcers, an organism can experience satiation and deprivation with secondary reinforcers. Among the Massagetians was Spargapises who ate and drank himself to inebriation and satiation. Satiation rates when eating depend on interactions of trait self-control and healthiness of the food. These satiation and alternation behaviors are evolutionarily adaptive. The vagus nerve also plays a role in satiation following food consumption. One may manipulate one's own behavior by affecting states of deprivation or satiation. Some initial conjectures related directly to the satiation of specific and general maternal hunger. Furthermore, intrinsic warm glow may be more resilient to satiation effects than extrinsic warm glow. For example, the process of satiation helps the organism maintain a stable internal environment (homeostasis). The characteristic of orthographic satiation as opposed to semantic satiation is that meaning remains intact. Predator satiation can be considered a type of refuge from predators. There are studies that also linked semantic satiation in education. The action of the bamboo is thought to be an ecological control mechanism (predator satiation).
