The auditory perception is a fundamental part of our interactions with and experience of the external environment. We receive considerable amount of information from our surroundings through sounds. The auditory system takes care of this continuous flow of information in a seemingly effortless manner. It functions as an adaptive and cognitive alarm system that scans our surroundings, detects an...

In this text, an unconventional paradigm for robotic multisensory perception and action will be presented in the form of a generalisation of a framework devised in previous work by the authors, the Bayesian Volumetric Map (BVM). The BVM, a log-spherical inference grid providing an egocentric and probabilistic representation of spatial information, was designed to bridge multisensory perception ...

In this paper we propose interactive visualization techniques which support the spatial comprehension of angiogram images by emphasizing depth information and introducing combined depth cues. In particular, we propose a depth based color encoding, two variations of edge enhancement and the application of a modified depth of field effect in order to enhance depth perception of complex blood vess...

This study examines the role of the magnocellular system in the early stages of face perception, in particular sex categorization. Utilizing the specific property of magnocellular suppression in red light, we investigated visually guided reaching to low and high spatial frequency hybrid faces against red and grey backgrounds. The arm movement curvature measure shows that reduced response of the...

Spatial localization is a basic process in vision, occurring reliably when people encounter an object or person. Yet the role of spatial-location in the visual perception of people is poorly understood. We explored the extent to which spatial-location distorts the perception of gender. Consistent with evidence that the perception of objects is constrained by their location in visual scenes, enh...

According to wide literature, a global impairment in the temporal and spatial domains as well as an increased crowding effect is common of dyslexics. The aim of the study was to evaluate if such subjects suffer from a more general impairment of spatial relationship perception (SRP) and in particular from anomalous spatial relationship anisotropy (SRA) thus accounting both for their global perce...

Human perception is highly flexible and adaptive. Selective processing is tuned dynamically according to current task goals and expectations to optimize behavior. Arguably, the major source of our expectations about events yet to unfold is our past experience; however, the ability of long-term memories to bias early perceptual analysis has remained untested. We used a noninvasive method with hi...

In this paper, evidences that visuo-spatial perception in the peri-personal space is not an abstract, disembodied phenomenon but is rather shaped by action constraints are reviewed. Locating a visual target with the intention of reaching it requires that the relevant spatial information is considered in relation with the body-part that will be used to perform the task. This entails the selectio...

We have proposed that haptic activation of the shape-selective lateral occipital complex (LOC) reflects a model of multisensory object representation in which the role of visual imagery is modulated by object familiarity. Supporting this, a previous functional magnetic resonance imaging (fMRI) study from our laboratory used inter-task correlations of blood oxygenation level-dependent (BOLD) sig...

Neuropsychological findings used to motivate the ‘‘two visual systems’’ hypothesis have been taken to endanger a pair of widely accepted claims about spatial representation in conscious visual experience. The first is the claim that visual experience represents 3-D space around the perceiver using an egocentric frame of reference. The second is the claim that there is a constitutive link betwee...
