Visual judgments of distance are often inaccurate. Nevertheless, information on distance must be procured if retinal image size is to be used to judge an object’s dimensions. In the present study, we examined whether kinesthetic information about an object’s distance—based on the posture of the arm and hand when holding it—influences the object’s perceived size. Subjects were presented with a computer simulation of a cube. This cube’s position was coupled to that of a rod in the subject’s hand…

Lack of depth constancy for grasping movements in both virtual and real environments.
TLDR
The findings clearly demonstrate that systematic biases in grasping actions are not induced by the use of virtual environments and that action and perception may involve the same visual information, which does not engage a metric reconstruction of the scene.
Grasping lacks depth constancy in both virtual and real environments.
TLDR
Comparisons of grasping movements performed in three experimental conditions demonstrate that systematic biases in grasping actions are not a prerogative of virtual environments and that the visuomotor system is subject to the same biases affecting perceptual estimates.
How removing visual information affects grasping movements
TLDR
The results show that occluding (part of) the hand’s movement path influences the movement trajectory from the beginning, and indicate that the control mechanisms are more complex than those suggested by current views on grasping.
Size, weight, and expectations
The size-weight illusion is well-known: if two equally heavy objects differ in size, the large one feels lighter than the small one. Most explanations for this illusion assume that because the
Observing and engaging in purposeful actions with objects influences estimates of their size
TLDR
The hypothesis that in vivo size estimation of familiar objects may employ a mechanism that derives size from memory and that size memory can be distorted by the way an object was used is supported.
Integration of haptics and vision in human multisensory grasping
TLDR
It is demonstrated that the availability of the haptic positional cue together with the visual cues is sufficient to achieve the same grasping performance as when all cues are available.
Modeling the Combination of Motion, Stereo, and Vergence Angle Cues to Visual Depth
TLDR
The simulation results suggest that relative to the weak and strong models, the modified weak fusion model is a good candidate model of the combination of motion, stereo, and vergence angle cues, although the results also highlight areas in which this model needs modification or further elaboration.

The Interaction of Oculomotor Cues and Stimulus Size in Stereoscopic Depth Constancy
TLDR
Binocular estimates of the heights and distances of planar surfaces of different sizes revealed that angular size and viewing distance interact in a similar way to determine perceived size and perceived distance.
Absolute motion parallax and the specific distance tendency
In the absence of definitive cues’to distance, the perceived distance of an object will be in error in the direction of the object appearing at a distance of about 2 m from O. This tendency to

This article reports a further investigation into the capacity to compare objects seen with objects touched. An earlier experiment had suggested that cross-modal comparisons are quite as accurate as

TLDR
The results reveal that vision is strongly dominant, often without the observer's being aware of a conflict.
