Oculomotor involvement in spatial working memory is task-specific

Keira Ball, David G. Pearson, Daniel T. Smith
2013 Cognition  
Abstract Many everyday tasks, such as remembering where you parked, require the capacity to store and manipulate information about the visual and spatial properties of the world.  ...  It is argued that the oculomotor system is required to encode and maintain spatial locations indicted by a change in physical salience, but not non-salient spatial locations indicated by the meaning of  ...  Acknowledgments This work was supported by the Economic and Social Research Council (RES-000-22-4457).

Dissociation of Spatial and Temporal Coupling in the Bimanual Movements of Callosotomy Patients

Elizabeth A. Franz, James C. Eliassen, Richard B. Ivry, Michael S. Gazzaniga
1996 Psychological Science  
Normal subjects produced deviations in the trajectories when spatial demands for the two hands were different, despite temporal .synchrony in the onset of bimanual movements, Callosotomy patients did not  ...  This neural dissociation indicates that spatial interference in movements results from callosat connections, whereas temporal synchrony in movement onset does not rely on the corpus ccdlosum.  ...  NS30256. and NS31443-02 from the National Institutes of Health and by the James S.

The Premotor theory of attention: Time to move on?

Daniel T. Smith, Thomas Schenk
2012 Neuropsychologia  
Secondly, spatial attention is functionally equivalent to planning goal directed actions such as eye-movements (i.e. planning an action is both necessary and sufficient for a shift of spatial attention  ...  Fourthly, the eye-movement system has a privileged role in orienting visual spatial attention. This article reviews empirical studies that have tested these predictions.  ...  These data indicate that proprioceptive information about eye-position plays an important role in spatial attention.  ...

Sources of variability in interceptive movements

Eli Brenner, Jeroen B. J. Smeets
2009 Experimental Brain Research  
How this is best achieved depends on the exact task, but to get an idea of what factors may limit performance we asked people to hit a moving virtual disk through a virtual goal, and analysed the spatial  ...  and temporal variability in the way in which they did so.  ...  We use an interception task that requires high spatial and temporal accuracy.  ...

Spatial Cognition in Teleost Fish: Strategies and Mechanisms

Fernando Rodríguez, Blanca Quintero, Lucas Amores, David Madrid, Carmen Salas-Peña, Cosme Salas
2021 Animals  
Teleost fish rely on a multiplicity of sensory cues and can use a variety of spatial strategies for navigation, ranging from relatively simple body-centered orientation responses to allocentric or "external  ...  For example, a crucial brain center for egocentric orientation in teleost fish is the optic tectum, which can be considered an essential hub in a wider brain network responsible for the generation of egocentrically  ...  local and directional information combined with these memories to orient and navigate through the environment.  ...

Oculomotor preparation as a rehearsal mechanism in spatial working memory

David G. Pearson, Keira Ball, Daniel T. Smith
2014 Cognition  
In this study we experimentally prevented healthy participants from planning or executing saccadic eye-movements during the encoding, maintenance, and retrieval stages of visual and spatial working memory  ...  One influential theory is that VSWM may involve activation of the eye-movement (oculomotor) system.  ...  Acknowledgments This work was supported by the Economic and Social Research Council (RES-000-22-4457).

Parietofrontal circuits in goal-oriented behaviour

W. Pieter Medendorp, Verena N. Buchholz, Jurrian Van Der Werf, Frank T. M. Leoné
2011 European Journal of Neuroscience  
Parietal and frontal cortical areas play important roles in the control of goal-oriented behaviour.  ...  After a survey of the functional specialization of these areas in monkeys, we discuss homologous regions in the human brain in terms of topographic organization, storage capacity, target selection, spatial  ...  Acknowledgements We thank our colleagues Jan Van Gisbergen and Tobias Heed for critical comments on previous versions of this manuscript.  ...

Event processing in the visual world: Projected motion paths during spoken sentence comprehension

Yuki Kamide, Shane Lindsay, Christoph Scheepers, Anuenue Kukona
2016 Journal of Experimental Psychology. Learning, Memory and Cognition  
Specifically, eye-movement effects started immediately after hearing the verb and were in line with data from an additional mouse-tracking task that encouraged a more explicit spatial reenactment of the  ...  In Experiment 1, participants listened to sentences describing the movement of an agent to a goal while viewing visual scenes depicting the agent, goal, and empty space in between.  ...  The first hypothesis (global orientation) predicts that verb-related spatial biases in eye-movements should be observable across the entire visual display.  ...

Interference between saccadic eye and goal-directed hand movements

H. Bekkering, Jos J. Adam, Ankie van den Aarssen, Herman Kingma, H. T. A. Whiting
1995 Experimental Brain Research  
Latencies of eye and hand movements in response to small and large visual target stimuli were measured while employing dual-task methodology.  ...  The aim of the present study was to investigate the nature of the interference effect when the eye is accompanied by a goal-directed hand movement rather than when the eye moves alone.  ...  Acknowledgements The authors thank Iwan de Jong and Harry Wandler for excellent technical assistance.  ...

From physiological principles to computational models of the cortex

Jeremy Fix, Nicolas Rougier, Frederic Alexandre
2007 Journal of Physiology - Paris  
In this article, we first discuss three levels at which a cortical circuit might be observed to provide a modeler with sufficient information to design a computational model and illustrate this principle  ...  Similarly, the advantages of such a joint approach are twofold: computational models are a powerful tool to experiment brain theories and assess them on the implementation of realistic tasks, such as visual  ...  , texture in various areas of the temporal lobe; eye, head and body centered information in the parietal lobe).  ...

Modeling the influence of action on spatial attention in visual interactive environments

Ali Borji, Dicky N. Sihite, Laurent Itti
2012 2012 IEEE International Conference on Robotics and Automation  
Comparing with other top-down task-driven and bottom-up spatio-temporal models, our approach shows higher NSS scores in predicting eye positions.  ...  In particular, two contributions this paper makes are: 1) employing multimodal information including mean eye position, gist of a scene, physical actions, bottom-up saliency, and tagged events for state  ...  Our goal in this study is to introduce a top-down spatial attention model which could automatically direct gaze based on task.  ...

Spatial memory guides task resumption

Raj M. Ratwani, J. Gregory Trafton
2008 Visual Cognition  
In this paper, we focus on the perceptual processes underlying task resumption and show that spatial memory guides task resumption.  ...  In Experiment 2, a spatial interruption disrupted resumption performance more than a nonspatial interrupting task. Together, these results implicate spatial memory as a mechanism for resumption.  ...  The goal of this experiment was to examine the pattern of eye movements upon resumption to determine whether a spatial representation is maintained and whether this representation allows for one to return  ...

Claus Lamm, Christian Windischberger, Ewald Moser, Herbert Bauer
2007 NeuroImage  
We are grateful to the anonymous reviewers for their highly valuable comments and their positive feedback.  ...  Processing of spatial orientation information One major goal of the present study was to test whether dPM is genuinely involved in the processing of visuo-spatial orientation information.  ...  Hemodynamic responses triggered by goal-directed eye movements (COMPARE), and by fixation (FIXATE) of a crosshair were separately assessed using an eye movement control condition.  ...
