Humas often tap into the processes of social and spatial cognition at the same time, for example, when regulating their spatial distance to each other based on sympathy, or when imagining a spatial perspective based on another person’s viewpoint. This temporal and functional proximity could lead to an partial overlap of spatial and social cognitive processes. We examine the social and spatial character of bodies and body parts, how social cues influence perceived distance and environments, and whether object orientation exhibits a social aspect as well.
Bodies are physical and social entities. Distinguishing one’s body from the world is probably the most basic form of self-representation. Humans use visual and somatosensory cues for estimating location and shape of their body and body parts. Our results showed that prior methods used to distinguish between visual and somatosensory representations are not specific for body parts as assumed before, but also apply to spatial objects and parallel findings in memory for spatial object arrangements. Another line of research is concerned with the full body illusion in which participants can feel that a virtual body in front of them is actually their body. Our results show that contrary to earlier conceptions this feeling of body identity and the subjective body location go hand in hand and are not separated. In the further course of this project we aim at examining effects of the visual full-body illusion on somatosensory body-part estimation.

Collaborative spatial problem solving
Almost all human-made objects involved collaborative spatial problem solving in the process of their construction or production. We aim to examine the underlying cognitive processes targeting at strategies, memory requirements, shared representations, and spatial transformations. First results on the case of collaborative search (e.g., firefighters searching a building for victims) indicate that collaborative in comparison to individual search might result in qualitative better, but not necessarily more efficient performance. We currently examine the interaction of working memory and search strategy and extend the problem to a collaborative 3D puzzle task.

Social influences on spatial perception
Within this project we examine potential social influences on room and distance perception. Results show cultural differences on the estimation of rooms. Participants also estimate virtual characters and objects facing them as closer than when they face away from them. Most humans and animals perceive and interact with their front. We currently examining whether social processes indicated by perceived animacy, relation to attention and social distances, or non-social object processing are responsible for the observed asymmetries.
