In 4 experiments, it was shown that hills appear steeper to people who are encumbered by wearing a heavy backpack (Experiment 1), are fatigued (Experiment 2), are of low physical fitness (Experiment 3), or are elderly and/or in declining health (Experiment 4). Visually guided actions are unaffected by these manipulations of physiological potential. Although dissociable, the awareness and action systems were also shown to be interconnected. Recalibration of the transformation relating awareness… 
Perceiving Slant 3 Perceived Slant : A Dissociation between Perception and Action
Perceived slant is grossly overestimated such that 5° hills look to be about 20°. However, overestimation is only found in visual and verbal measures of apparent slant; action measures are accurate.
Rapid recalibration based on optic flow in visually guided action

TLDR
Two experiments showed that actors rapidly recalibrate following a change in brake dynamics, even when they are unaware of the change, suggesting that information in the sensory consequences of the initial brake adjustment is sufficient for recalibration, even in the absence of feedback about the outcome.
Perceived Slant: A Dissociation between Perception and Action
TLDR
The results are consistent with the hypothesis that two perceptual processes underlie the dissociation between explicit awareness and visuomotor assessments of perceived slant.
Embodied Perception and the Economy of Action

Perception informs people about the opportunities for action and their associated costs. To this end, explicit awareness of spatial layout varies not only with relevant optical and ocular-motor
Awareness Is Not a Necessary Characteristic of a Perceptual Effect

TLDR
It is argued that awareness is not a necessary condition for an effect to be perceptual, as evidenced by a lack of awareness in the case of a classic visual illusion.
Perceiving virtual geographical slant: action influences perception.
TLDR
The authors found that in all conditions, perceptual judgments were overestimated and motoric adjustments were more accurate than in previous studies, and the virtual environment allowed manipulation of the effort required to walk up simulated hills.
Dissociating perception and action in Kanizsa’s compression illusion
TLDR
This study is the first in which a comparison of size perception in personal space with bilateral actions performed with both hands is used to investigate motor responses to Kanizsa’s compression illusion.
When and how are spatial perceptions scaled?
TLDR
The results supported the action-specific account, which proposes that the angular information inherent in optic flow and ocular-motor adjustments is rescued and transformed into units related to intended actions.
19. Model-Based Control of PerceptionIAction
The coupling of perception and action in humans and other species is one of the major questions in cognitive science and neuroscience. The empirical domain of perceptionlaction includes reaching and
Two memories for geographical slant: Separation and interdependence of action and awareness
TLDR
The present study extended previous findings of geographical slant perception, in which verbal judgments of the incline of hills were greatly overestimated but motoric (haptic) adjustments were much more accurate than those given when viewing hills.

Two memories for geographical slant: Separation and interdependence of action and awareness
TLDR
The present study extended previous findings of geographical slant perception, in which verbal judgments of the incline of hills were greatly overestimated but motoric (haptic) adjustments were much more accurate than those given when viewing hills.
Visual space perception and visually directed action.
TLDR
Performance was quite accurate in both motoric tasks, indicating that the distortion in the mapping from physical to visual space evident in the visual matching task does not manifest itself in the visually open-loop motoric task.
Optic ataxia: a specific disruption in visuomotor mechanisms. I. Different aspects of the deficit in reaching for objects.
TLDR
The findings suggest that the 2 types of visuomotor mechanisms responsible for the proximal and distal components of visually-directed arm movements are controlled by the parietal cortex and that there should exist a hemisphere asymmetry in the functional organization of these mechanisms.
Perceiving geographical slant
TLDR
It is proposed that the perceived exaggeration of geographical slant preserves the relationship between distal inclination and people’s behavioral potential, thereby enhancing sensitivity to the small inclines that must actually be traversed in everyday experience.
Perception and action in 'visual form agnosia'.
TLDR
It is proposed that many of these perceptual disorders might be the combined result of a selective loss of the cortical elaboration of the magnocellular visual processing stream, and a selective output disconnection from a central processor of visual boundaries and shape primitives in the occipital cortex.
Relation between cognitive and motor-oriented systems of visual position perception.
Although subjects failed to detect a target displacement if it occurred near the time of a saccadic eye movement (a cognitive visual task), they were still able to point to the center of the target
Large adjustments in visually guided reaching do not depend on vision of the hand or perception of target displacement
TLDR
Evidence is presented that a change in the position of a visual target during a reaching movement can modify the trajectory even when vision of the hand is prevented, and the mechanisms that maintain the apparent stability of a target in space are dissociable from those that mediate the visuomotor outputdirected at that target.
A Selective Impairment of Hand Posture for Object Utilization in Apraxia
Omnidirectional increase in threshold for image shifts during saccadic eye movements
TLDR
The failure of subjects todetect target movements occurring during eyemovements provides a tool for investigating themechanism which accomplishes subjective stabiliza­tion.
