Results revealed that the haptic oblique effect occurs when the sensory motor traces associated with exploratory movement are represented more abstractly at a cognitive level.Abstract:
This review examines the isotropy of the perception of spatial orientations in the haptic system. It shows the existence of an oblique effect (i.e., a better perception of vertical and horizontal orientations than oblique orientations) in a spatial plane intrinsic to the haptic system, determined by the gravitational cues and the cognitive resources and defined in a subjective frame of reference. Similar results are observed from infancy to adulthood. In 3D space, the haptic processing of orientations is also anisotropic and seems to use both egocentric and allocentric cues. Taken together, these results revealed that the haptic oblique effect occurs when the sensory motor traces associated with exploratory movement are represented more abstractly at a cognitive level.read more

Haptic perception: a tutorial.
TL;DR: This tutorial focuses on the sense of touch within the context of a fully active human observer and describes an extensive body of research on “what” and “where” channels, the former dealing with haptic perception of objects, surfaces, and their properties, and the latter with perception of spatial layout on the skin and in external space relative to the perceiver.

Tactile and Haptic Illusions
TL;DR: This paper surveys the research literature on robust tactile and haptic illusions by briefly considering a number of important general themes that have emerged in the materials surveyed.

Perception of upright: Multisensory convergence and the role of temporo-parietal cortex
Amir Kheradmand,Ariel Winnick +1 more
TL;DR: This review focuses on neural mechanisms that subserve orientation constancy within the cerebral cortical networks involved in perception of spatial orientation, sensory models that address the neurophysiology underlying perception of upright, and the current evidence for the role of cerebral cortex.

Spatial orientation constancy is impaired in anorexia nervosa
TL;DR: The findings reinforce the role of the PC in anorexia nervosa and suggest that this dysfunction affects spatial orientation constancy as well as body boundaries.

Perceived self-orientation in allocentric and egocentric space: effects of visual and physical tilt on saccadic and tactile measures
TL;DR: Perception of allocentric and egocentric space is likely influenced by multiple senses that define common egOCentric and allocentric frames of reference accessible for saccadic and tactile estimates of perceived self-orientation.

Hand movements: a window into haptic object recognition.
TL;DR: Two experiments establish links between desired knowledge about objects and hand movements during haptic object exploration, and establish that in free exploration, a procedure is generally used to acquire information about an object property, not because it is merely sufficient, butBecause it is optimal or even necessary.

A neurological dissociation between perceiving objects and grasping them
TL;DR: The quantitative analyses demonstrate strikingly accurate guidance of hand and finger movements directed at the very objects whose qualities she fails to perceive and suggest that the neural substrates for the visual perception of object qualities such as shape, orientation and size are distinct from those underlying the use of those qualities in the control of manual skills.

Observations on active touch.
TL;DR: Preliminary results indicate that the cross-modal matching of these novel preceptions is possible even for a naive observer, and that practice can bring about errorless judgments in all observers so far tested.
