Higher-level perceptual inferences result from the combination of various kinds of information that may also originate from different sensory modalities. Here, we investigate the principles underlying the organization of higher-level neural representations and study how neural populations serve to integrate information from multiple sources. The central research questions are:

• Is prior knowledge encoded in an amodal or modality-specific fashion? What are the changes when moving from basic multi-modal cue integration tasks to spatial cognition or representation of numerosity?
• How is knowledge about priors acquired and generalised to novel conditions?
• What are the relevant time-scales for learning priors?
• How is information from sources with different reliability integrated?
