Structural Equation Modeling of Spatial Presence: The Influence of Cognitive Processes and Traits

This article examines the formation process of spatial presence, which is conceived as a two-step process involving the construction of a mental model of the mediated environment, followed by the emergence of spatial presence. During both stages, cognitive processes and user traits are in effect. We present data derived from a pooled set of data of three studies using the same virtual environment. Structural equation modeling is used to confirm the proposed theoretical model. The results show that attention and the trait of visual spatial imagery are positive predictors of the mental model of the mediated environment. In the second step, the formation of spatial presence is governed by involvement, the suspension of disbelief, and the domain-specific interest, together with the mental model.     

Multisensory self‐motion encoding in parietal cortex

Navigation through the environment requires the brain to process a number of incoming sensory signals, such as visual optical flow on the retina and motion information originating from the vestibular organs. In addition, tactile as well as auditory signals can help to disambiguate the continuous stream of incoming information and determining the signals resulting from one's own set of motion. In this review I will focus on the cortical processing of motion information in one subregion of the posterior parietal cortex, i.e., the ventral intraparietal area (VIP). I will review (1) electrophysiological data from single cell recordings in the awake macaque showing how self‐motion signals across different sensory modalities are represented within this area and (2) data from fMRI recordings in normal human subjects providing evidence for the existence of a functionally equivalent area of macaque area VIP in the human cortex.
