April 29,
2011: As
a follow-up of the conference entitled "Perception & Action - An
Intredisciplinary Approach to Cognitive Systems Theory", which took
place September 14-16, 2010 at the Santa Fe Institute, NM, USA, key
findings, perspectives and future challenges in the field are presented
and discussed.

- February 1, 2011: An active binocular
vision system with saccade and vergence capabilities mimic
fundamental human vision. The combination of saccadic and vergence
mechanisms provides the system a way to explore and reconstruct
positional information of attended objects in the environment.

2010: A
persistent question has been whether it is depth cues or depth cues or
depth perception that guides saccades and vergence eye movements. The
study has shown that saccdes and perception combine disparity and
perspective cues to depth in a similar way. Contrary to perception and
saccades, vergence seems dominated by a single cue, binocular
disparity.

- April 26,
2010: The
study aimed at understanding how the estimation of egocentric distance
is affected by exposure to systematic visual alteration the distance
estimation aftereffect of two components: a response to a sustained
results convergence demand onto the oculomotor system, and a response
to an inter-sensory conflict or to a conflict between expected and
actual visual feedback.

July 02, 2009: Perisaccadic shift
might be caused by neural representations of eye position or space that
are plastic and that arise from non-motor, extraretinal mechanisms.
This suggests a perceptual system that continuously calibrates itself
in response to changes in oculomotor and muscle systems to reconstruct
a stable percept of the world.
