Illusions as a tool to study the coding of pointing movements

DDJ de Grave, E Brenner, JBJ Smeets - Experimental Brain Research, 2004 - Springer
Pictorial illusions bias our judgments about certain visual attributes. Such illusions are
therefore only expected to influence a task if these attributes are used to perform the task …

[HTML][HTML] The influence of the Brentano illusion on eye and hand movements

DDJ de Grave, VH Franz, KR Gegenfurtner - Journal of Vision, 2006 - jov.arvojournals.org
When making an eye movement and a hand movement toward a visual target, the
movements could be guided by visual judgments of direction and distance (or length) of the …

Is there dissociation of perceptual and motor responses to figural illusions?

RB Post, RB Welch - Perception, 1996 - journals.sagepub.com
Open-loop reaching for locations within figural illusions was measured in three experiments.
The experiments differed with respect to whether subjects were provided a visible target …

The Ponzo illusion affects grip-force but not grip-aperture scaling during prehension movements.

SR Jackson, A Shaw - Journal of Experimental Psychology …, 2000 - psycnet.apa.org
Contextual cues such as linear perspective and relative size can exert a powerful effect on
the perception of objects. This fact is demonstrated by the illusory effects that can be induced …

A coordinate system for the synthesis of visual and kinesthetic information

SI Tillery, M Flanders, JF Soechting - Journal of Neuroscience, 1991 - Soc Neuroscience
The results of this study suggest that information derived from kinesthetic inputs alone is not
normally used to generate an estimate of the location of the hand in extrapersonal space …

Visual illusion and action

M Gentilucci, S Chieffi, E Daprati, MC Saetti, I Toni - Neuropsychologia, 1996 - Elsevier
The role of allocentric cues on movement control was investigated in the present study.
Pointing movements directed to the more distant vertex of closed and open configurations of …

How does action resist visual illusion? Uncorrected oculomotor information does not account for accurate pointing in peripersonal space

P Bernardis, P Knox, N Bruno - Experimental Brain Research, 2005 - Springer
Using spatially identical displays (variants of the Müller–Lyer illusion), we compared the
accuracy of spatial verbal judgments with that of saccadic (eye) and pointing (hand) …

Dissociating visual and kinesthetic coordinates during pointing movements

M Gentilucci, M Jeannerod, B Tadary… - Experimental brain …, 1994 - Springer
Goal-directed movements imply that the visual coordinates in which the localisation of the
goal is coded are transformed into proprioceptive coordinates in which the arm movement is …

Why are saccades influenced by the Brentano illusion?

DDJ de Grave, JBJ Smeets, E Brenner - Experimental Brain Research, 2006 - Springer
In the Brentano version of the Müller-Lyer illusion one part looks longer and the other looks
shorter than it really is. We asked participants to make saccadic eye movements along these …

Amplitude and direction errors in kinesthetic pointing

G Baud-Bovy, P Viviani - Experimental brain research, 2004 - Springer
We investigated the accuracy with which, in the absence of vision, one can reach again a 2D
target location that had been previously identified by a guided movement. A robotic arm …
