On the link between attentional search and the oculomotor system: is pre-attentive search restricted to the range of eye movements? (2020)
Journal Article
Casteau, S., & Smith, D. (2020). On the link between attentional search and the oculomotor system: is pre-attentive search restricted to the range of eye movements?. Attention, Perception, and Psychophysics, 82(2), 518-532. https://doi.org/10.3758/s13414-019-01949-4

It has been proposed that covert visual search can be fast, efficient, and stimulus driven, particularly when the target is defined by a salient single feature, or slow, inefficient, and effortful when the target is defined by a nonsalient conjunctio...

Associations and Dissociations between Oculomotor Readiness and Covert Attention (2019)
Journal Article
Casteau, S., & Smith, D. (2019). Associations and Dissociations between Oculomotor Readiness and Covert Attention. Vision, 3(2), Article 17. https://doi.org/10.3390/vision3020017

The idea that covert mental processes such as spatial attention are fundamentally dependent on systems that control overt movements of the eyes has had a profound influence on theoretical models of spatial attention. However, theories such as Klein’s... Read More about Associations and Dissociations between Oculomotor Readiness and Covert Attention.

Covert Attention Beyond the Range of Eye-movements: Evidence for a Dissociation between Exogenous and Endogenous orienting (2018)
Journal Article
Casteau, S., & Smith, D. (2020). Covert Attention Beyond the Range of Eye-movements: Evidence for a Dissociation between Exogenous and Endogenous orienting. Cortex, 122, 170-186. https://doi.org/10.1016/j.cortex.2018.11.007

The relationship between covert shift of attention and the oculomotor system has been the subject of numerous studies. A widely held view, known as Premotor Theory, is that covert attention depends upon activation of the oculomotor system. However, r...

The effect of offset cues on saccade programming and covert attention (2018)
Journal Article
Smith, D., & Casteau, S. (2019). The effect of offset cues on saccade programming and covert attention. Quarterly Journal of Experimental Psychology, 72(3), 481-490. https://doi.org/10.1177/1747021818759468

Salient peripheral events trigger fast, “exogenous” covert orienting. The influential premotor theory of attention argues that covert orienting of attention depends upon planned but unexecuted eye-movements. One problem with this theory is that salie...

The magnification-factor accounts for the greater hypometria and imprecision of larger saccades: Evidence from a parametric human-behavioral study (2017)
Journal Article
Vitu, F., Casteau, S., Adeli, H., Zelinsky, G., & Castet, E. (2017). The magnification-factor accounts for the greater hypometria and imprecision of larger saccades: Evidence from a parametric human-behavioral study. Journal of Vision, 17(4:2), 1-38. https://doi.org/10.1167/17.4.2

Saccades quite systematically undershoot a peripheral visual target by about 10% of its eccentricity while becoming more variable, mainly in amplitude, as the target becomes more peripheral. This undershoot phenomenon has been interpreted as the stra...

An image-based population model of human saccade programming in the Superior Colliculus (2014)
Journal Article
(2014). An image-based population model of human saccade programming in the Superior Colliculus. Journal of Vision, 14(10), 1215-1215. https://doi.org/10.1167/14.10.1215

Models of saccade programming in the superior colliculus (SC) have been limited in what inputs they can accept, typically isolated coordinates in visual space (e.g., Ottes et al., 1986, Vision Research [1]). We addressed this problem by integrating [... Read More about An image-based population model of human saccade programming in the Superior Colliculus.

How the distorted representation of visual space in our brain constrains the way we move our eyes. (2014)
Journal Article
(2014). How the distorted representation of visual space in our brain constrains the way we move our eyes. https://doi.org/10.1167/14.10.751

The representation of visual space is distorted in several areas of the brain, including the Superior Colliculus (SC) where population averaging presumably determines the amplitude of saccadic eye movements. We previously showed, based on human behav... Read More about How the distorted representation of visual space in our brain constrains the way we move our eyes..
