History of Isolation Research
Nathaniel Rich delves into the history of isolation research, noting that past studies have established the detrimental impacts of prolonged and confined isolation on the human psyche.
Studies examining the psychological effects of confinement
Various experiments have documented the psychological challenges that arise from isolation.
Hebb's sensory deprivation experiments showing intellectual impairment, attitude changes, hallucinations
Donald O. Hebb's research at McGill University played a pivotal role in understanding isolation's effects on mental functions. Hebb's studies revealed that intellectual impairment, attitude changes, and hallucinations were among the outcomes for subjects who were exposed to extended periods of monotony. The subjects, who initially engaged in deep sleep and contemplation, eventually lost their ability to maintain focus, encountered blank periods, and reported experiencing surreal hallucinations.
Other isolation studies confirming similar effects of monotony on human psyche
Rich further cites examples from history that confirm Hebb's findings. During World War II, British Royal Air Force pilots on solo reconnaissance flights exhibited a decline in performance due to the monotony of prolonged missions. Subsequent experiments involved subjects being confined in subterranean caves or small, bright cockpits, which led to irritability, hostility, and hallucinations—some cases being exacerbated by the administration of amphetamines.
Moreover, modern experiments like the HI-SEAS Mars simulations, conducted between 2013 and 2017, studied how volunteers adapted to isolated living conditions. ...

- The lag in communication due to the distance to "Mars" is a reference to the delay in sending and receiving messages between Earth and Mars. Because of the vast distance between the two planets, it can take anywhere from a few minutes to over 20 minutes for a signal to travel one way. This delay can impact real-time conversations and interactions between individuals on Earth and those on a simulated Mars mission. The communication delay is a significant challenge that astronauts and their families must navigate during missions to distant planets.
- When a scent triggers a memory, it can evoke strong emotions and vivid recollections tied to past experiences. This phenomenon is due to the close connection between the brain regions responsible for processing smell and memory. Scent can elicit nostalgic feelings, transport individuals back in time, and create a profound emotional response. The olfactory system's direct link to the brain's limbic system, associated with emotions and memories, plays a significant role in how scents can trigger powerful emotional reactions.
- Preparing a bittersweet last meal before a departure is a symbolic gesture that signifies the impending separation and the emotional weight of the upcoming journey. It serves as a poignant moment of connection and reflection between individuals who are about to part ways for an extended period. The act of preparing and sharing a meal can convey deep emotions, nostalgia, and the acknowledgment of the temporary nature of the current togetherness.
