Both psychophysical and physiological studies have examined plasticity of spatial auditory processing. While there is a great deal known about how the system computes basic cues that influence spatial perception, less is known about how these cues are integrated to form spatial percepts and how the auditory system adapts and calibrates in order to maintain accurate spatial perception. After sum...

This paper considers interaction of the human arm with "virtual" objects simulated mechanically by a planar robot. Haptic perception of spatial properties of objects is distorted. It is reasonable to expect that it may be distorted in a geometrically consistent way. Three experiments were performed to quantify perceptual distortion of length, angle and orientation. We found that spatial percept...

One of the primary functions of the sensory nervous system is to determine and represent where stimuli originate from. This is critical for identifying predators and prey, as well as mate selection and attending objects of interest. Audition is one of the three primary senses that can provide some information about extrapersonal space, together with vision and olfaction. The latter two sensory ...

The recognition of facial affect is a core component of social cognition and is influenced by bottom-up and topdown processes. Spatial frequency-specific processing is a fundamental mechanism underpinning visual perception that also contributes to emotion processing. Yet, it remains relatively unclear how this bottom-up process modulates analysis of affect signals. In this study, face images we...

Several lines of evidence show that visual perception is altered at the locus of visual attention: detection is faster, performance better and spatial resolution increased. It is however not known whether attention can affect visual perception further away from its locus. In the present study, we specifically question whether and how visual attention influences spatial perception away from its ...
