Autism: tactile perception and emotion

Journal of Intellectual Disability Research, 2007
AbstractBackground  For many years, and especially since Waynbaum and Wallon, psychology and psychopathology have dealt with cognitive perception, but have had little to do with the affective qualities of perception. Our aim was to study the influence of the sensory environment on people with autism.Method  Several experiments were carried out using ...

Neutral networks for tactile perception

Proceedings. 1988 IEEE International Conference on Robotics and Automation, 2003
The real-time solution to a basic inverse problem of tactile perception is investigated. Regularized solutions of this problem are obtained by a neural-analog network. Favorable setting times and noise immunity are observed in simulations and breadboard level experiments. >

The tactile perception of stimulus orientation

Somatosensory & Motor Research, 2008
Studies of the visual system suggest that, at an early stage of form processing, a stimulus is represented as a set of contours and that a critical feature of these local contours is their orientation. Here, we characterize the ability of human observers to identify or discriminate the orientation of bars and edges presented to the distal fingerpad ...

Cortical adaptation and tactile perception

Nature Neuroscience, 2014
Cortical neurons reduce spiking responses to repetitive sensory stimulation, but the perceptual impact of this adaptation has been difficult to assess. Work now shows that it has profound consequences for tactile perception.

An approach to integrated tactile perception

Proceedings of International Conference on Robotics and Automation, 2002
This paper presents an integrated approach to tactile perception, both in terms of data acquisition and data interpretation. In humans, touch sensing is implemented through a number of different sensing elements embedded in the skin. The interpretation of perceived data to the level of detection of basic features, such as material, shape of surface ...

Tactile Perception of Digital Images

2017
This paper introduces a prototype system of the tactile perception of digital images. The prototype system is comprised of several models, which include automatic image segmentation, texture shape recovery, multi-points interaction, real-time image deformation, and texture tactile rendering. For a common digit image, the prototype system in some extent

Psychophysical Dimensions of Tactile Perception of Textures

IEEE Transactions on Haptics, 2013
This paper reviews studies on the tactile dimensionality of physical properties of materials in order to determine a common structure for these dimensions. Based on the commonality found in a number of studies and known mechanisms for the perception of physical properties of textures, we conclude that tactile textures are composed of three prominent ...

Robotic tactile perception

IMTC/99. Proceedings of the 16th IEEE Instrumentation and Measurement Technology Conference (Cat. No.99CH36309), 2003
The paper presents a review of the biological basis and technological implementation issues of robotic tactile perception. Sensor construction and kinesthetic probing aspects are discussed for an experimental tactile perception system.

Sex Differences in The Perception of Tactile Simultaneity

Cortex, 2000
A tactile simultaneity task was used to investigate the effects of sex on simultaneity thresholds. Participants were required to judge whether pairs of tactile stimuli delivered unimanually or bimanually were simultaneous. Unimanual stimulation delivered stimuli to the same cerebral hemisphere, while bimanual stimulation resulted in the delivery of one

Application of Tactile Perception Enhancement

2010
Surrounding environment is mainly perceived through sight and hearing. Our sense of touch is mostly dedicated to explore the surface of objects using hands and fingers. Tactile sensitivity of the body skin is rather limited in common life, however this represents a viable channel to pass information.
