![]() Blood Pressure and Heart Rate in the Rabbit During Animal Hypnosis. The researchers say this suggests that tonic immobility is preserved in humans as an involuntary defensive strategy.Ĭarli, G. ![]() Some participants reported immobility while listening to the description, and this was associated with increased heart rate and diminished heart rate variability. In one study, participants with post-traumatic stress disorder listened to descriptions of their own traumas as scientists took physiological measurements. Tonic immobility has been hypothesized to happen in humans who are facing an intense trauma such as sexual assault. In evolutionary terms, this makes sense: a quiet, compact baby is easier for a mother to carry away from danger. In 2013, scientists found that in both mice and humans, a mother carrying an infant causes three similar responses in the infant: passivity, a decreased heart rate, and a cessation of crying. The researchers concluded that the response to PIBI makes it easier for mother cats to carry their kittens. Also unlike an animal in a tonic state, the cats remained responsive. It's not a fear or pain response the cats didn't show any dilated pupils, increased heart rate, or faster breathing. PIBI seems to be different from tonic immobility. The majority of the cats had a positive response to the treatment, becoming passive, curling their spines, and dipping their tails between their legs. In one study, scientists induced PIBI in cats by placing standard 2-inch binder clips along the loose skin at the napes of their necks. Distributed under a CC-BY-SA 3.0 license. It's been used by scientists studying farm animal welfare to determine when chickens are most fearful for instance, hens in cages are more fearful than those in pens, and hens on the top tier of battery cages are more fearful than those on the lower levels. Tonic immobility in chickens is thought to be a defensive mechanism caused by fear. If you start the line right in front of the chicken's beak and draw it straight out, the chicken will focus on the line and remain immobile anywhere from 15 seconds to 30 minutes. The chicken will focus on your finger.Īnother method is to put the chicken on the ground on its stomach and then draw a line in the dirt with a stick or your finger. You can wave your finger in front of its face - starting with your finger close to its beak and then pulling your finger slowly straight back. You can lay it on its side, tuck its head under its wing and gently rock it, or put it on its back and stroke its sternum. There are several ways to "mesmerize" a chicken.
