Scale errors offer evidence for a perception-action dissociation early in life.
We report a perception-action dissociation in the behavior of normally developing young children. In adults and older children, the perception of an object and the organization of actions on it are seamlessly integrated. However, as documented here, 18- to 30-month-old children sometimes fail to use information about object size and make serious attempts to perform impossible actions on miniatu...
متن کاملPerceived slant: a dissociation between perception and action.
Perceived slant is grossly overestimated, such that 5 degrees hills look to be about 20 degrees. However, overestimation is found only in visual and verbal measures of apparent slant; action measures are accurate. This dissociation is consistent with several lines of research that suggest that there exist two perceptual processes, one for visually guided actions and another for explicit awarene...
متن کاملNo dissociation between perception and action in patient DF when haptic feedback is withdrawn.
Goodale et al. (1991) reported a striking dissociation between vision for perception and action. They examined DF, a human patient who had damage to her ventral visual stream and suffered from visual form agnosia. She was unable to perceive an object's size but could match the opening of her hand to the object's size during grasping. It was concluded that grasping relied on a separate represent...
متن کاملPerception-Action Dissociation Generalizes to the Size-Inertia Illusion Running title: Perception-Action Dissociation in Size-Mass Illusions
Two objects of similar visual aspects and of equal mass, but of different sizes, generally do not elicit the same percept of heaviness in humans. The larger object is consistently felt to be lighter than the smaller, an effect known as the ‘size-weight illusion’. We investigated whether the same effect can be observed if the mass of an object is available to participants through inertial rather...
متن کاملDissociation of perception and action in audiovisual multisensory integration
The 'temporal rule' of multisensory integration (MI) proposes that unisensory stimuli, and the neuronal responses they evoke, must fall within a window of integration. Ecological validity demands that MI should occur only for physically simultaneous events (which may give rise to non-simultaneous neural activations), and spurious neural response simultaneities unrelated to environmental multise...
