pubmed-article:19170102 | pubmed:abstractText | Tonic immobility (TI) is a temporary state of motor inhibition believed to be a response to situations involving extreme fear. Limited attention has been directed to studying TI in humans; however, the phenomenon has been well documented in the animal literature. In humans, TI is believed to occur during sexual assault, and there have been reports of fear-induced freezing in the contexts of air, naval, and other disasters. | lld:pubmed |
