The idea
John Cacioppo and Louise Hawkley's research treats loneliness as perceived social isolation: what matters is the perception, not the number of people around you.
In practice
Someone in a busy open-plan office, surrounded by colleagues and deeply lonely.
Where people slip
Their two thousand nine review links loneliness to poorer cognitive performance, poorer executive functioning and heightened sensitivity to social threat.
