Flexible construction of visual spatial relations

There is significant work on how we recognize structure within objects and scenes that we have previously encountered. But we have strikingly little understanding of how the visual system flexibly represents spatial structure across arbitrary arrangements of objects (e.g. displays such as graphs or diagrams). I will review a set of possible visual mechanisms and argue for a counter-intuitive possibility – that relations across space are coded by changes in the location of the attentional 'spotlight' over time.
