DESCRIPTION:The sources that guide attention are manifold and interact in 
 complex ways. Internal goals\, task rules\, or salient external stimuli ha
 ve shown to be some of the strongholds of attentional control. But what gu
 ides attention in complex\, real-world environments? I have been arguing f
 or a while now that attention during scene viewing is mainly controlled by
  generic scene knowledge regarding the meaningful composition of objects t
 hat make up a scene (a.k.a. scene grammar). Contrary to arbitrary target o
 bjects placed in random arrays of distractors\, objects in naturalistic sc
 enes are placed in a very rule-governed manner. That is\, different types 
 of scene priors — i.e. expectations regarding what objects (scene semant
 ics) are supposed to be where (scene syntax) within a scene — strongly g
 uide attention. Violating such semantic and syntactic scene priors results
  in differential ERP responses similar to the ones observed in sentence pr
 ocessing and might suggest some commonality in the mechanisms for processi
 ng meaning and structure across a wide variety of cognitive tasks. In this
  talk\, I will highlight some recent projects from my lab in which we have
  tried to shed more light on the hierarchical nature of scene grammar. In 
 particular\, a certain type of objects\, which we have started to call “
 anchor objects”\, seems to play a crucial role during visual search\, ob
 ject perception and memory in naturalistic environments.
