HOME. Without doubt, it’s one of the most evocative words in any language. Whether it’s a suburban semi, igloo, yurt or a particular patch of desert, the familiarity and domesticity of home usually provokes relief when you arrive.

But why? What is it about being in a specific place that makes us feel so good? Why is being away from home so stressful for some that US psychologists once recognised homesickness as a potent progenitor of mental illness in recent immigrants? All this, and much more, is explained in John S. Allen’s book Home.

New Scientist. Science news and long reads from expert journalists, covering developments in science, technology, health and the environment on the website and the magazine.
Allen is a proponent of and researcher in the newish field of neuroanthropology – the study of the relationships between culture and the brain – a science that owes its quantitative existence to technological advances in brain imaging. Without the ability to localise what, where and by how much, the study of emotional responses lay forever in the qualitative realm. Techniques like MRI, fMRI and arterial spin labelling all allow cunning investigators to start teasing out long inaccessible answers about what it is to be human, how we got this way, and the links to our animal antecedents.

Allen uses these tools to explore the privileged place of home in our cognition, while introducing us to as many as 17 emotions, Neanderthal homemaking and five psychological roots of economic cycles.

More than anything, research by Allen and his colleagues shows that notions of sanctuary, certainty and the consequent capacity to relax are key to our concept of home, how we identify it and why we need it. An affirming read for the commute home.
