So much of our experiences as people rests upon the spaces and environments we occupy and traverse. In particular, the rooms where we socialize, rest, eat, learn and work have a heavy bearing on who we are and how we live. But when these spaces change, how does that process affect us? This week, Mark Ashin joins us to discuss the phenomenon of rooms shifting in time and how our memories and perceptions are tied not only to rooms themselves, but particular decorations or appearances the room might take on.
