Sumario:As humanity prepares for deep space exploration, understanding the impact of spaceflight on bodily physiology is critical. While the effects of non-terrestrial gravity on the body are well established, little is known about its impact on human behaviour and cognition. Astronauts often describe dramatic alterations in sensorimotor functioning, including orientation, postural control, and balance. Changes in cognitive functioning as well as in socio-affective processing have also been observed. Strikingly, no comprehensive theoretical model exists to outline the impact of non-terrestrial gravity on behaviour. Here, we have reviewed the key literature across the last 10 years and explored the impact of non-terrestrial gravity across three key functional domains: sensorimotor functioning, cognition, and socio-affective processing. We have proposed and preliminary validated a neurocognitive model to account for the effects of non-terrestrial gravity in these domains. Understanding the impact of non-terrestrial gravity on human behaviour has never been timelier and it will help mitigate against risks in both commercial and non-commercial spaceflight.
