Object-based attentional facilitation and inhibition are neuropsychologically dissociated (2015)
Journal Article
Smith, D., Ball, K., Swalwell, R., & Schenk, T. (2016). Object-based attentional facilitation and inhibition are neuropsychologically dissociated. Neuropsychologia, 80, 9-16. https://doi.org/10.1016/j.neuropsychologia.2015.11.003

Salient peripheral cues produce a transient shift of attention which is superseded by a sustained inhibitory effect. Cueing part of an object produces an inhibitory cueing effect (ICE) that spreads throughout the object. In dynamic scenes the ICE sta...

Dissociating the neural mechanisms of distance and spatial reference frames (2014)
Journal Article
Lane, A. R., Ball, K., & Ellison, A. (2015). Dissociating the neural mechanisms of distance and spatial reference frames. Neuropsychologia, 74, 42-49. https://doi.org/10.1016/j.neuropsychologia.2014.12.019

This study investigated if the neural mechanisms involved in processing distance (near and far) and frame of reference (egocentric and allocentric) can be dissociated. 36 participants completed a conjunction visual search task using either an egocent...

The role of the oculomotor system in covert social attention (2014)
Journal Article
Morgan, E., Ball, K., & Smith, D. (2014). The role of the oculomotor system in covert social attention. Attention, Perception, and Psychophysics, 76(5), 1265-1270. https://doi.org/10.3758/s13414-014-0716-1

Observing a change in gaze direction triggers a reflexive shift of attention and appears to engage the eye-movement system. However, the functional relationship between social attention and this oculomotor activation is unclear. One extremely influen...

Oculomotor preparation as a rehearsal mechanism in spatial working memory (2014)
Journal Article
Pearson, D., Ball, K., & Smith, D. (2014). Oculomotor preparation as a rehearsal mechanism in spatial working memory. Cognition, 132(3), 416-428. https://doi.org/10.1016/j.cognition.2014.05.006

There is little consensus regarding the specific processes responsible for encoding, maintenance, and retrieval of information in visuo-spatial working memory (VSWM). One influential theory is that VSWM may involve activation of the eye-movement (ocu... Read More about Oculomotor preparation as a rehearsal mechanism in spatial working memory.

Functional Interaction between Right Parietal and Bilateral Frontal Cortices during Visual Search Tasks Revealed Using Functional Magnetic Imaging and Transcranial Direct Current Stimulation (2014)
Journal Article
Ellison, A., Ball, K., Moseley, P., Dowsett, J., Smith, D., Weis, S., & Lane, A. (2014). Functional Interaction between Right Parietal and Bilateral Frontal Cortices during Visual Search Tasks Revealed Using Functional Magnetic Imaging and Transcranial Direct Current Stimulation. PLoS ONE, 9(4), Article e93767. https://doi.org/10.1371/journal.pone.0093767

The existence of a network of brain regions which are activated when one undertakes a difficult visual search task is well established. Two primary nodes on this network are right posterior parietal cortex (rPPC) and right frontal eye fields. Both ha...

Covert visual search within and beyond the effective oculomotor range (2013)
Journal Article
Smith, D., Ball, K., & Ellison, A. (2014). Covert visual search within and beyond the effective oculomotor range. Vision Research, 95, 11-17. https://doi.org/10.1016/j.visres.2013.12.003

Covert spatial attention is tightly coupled to the eye-movement system, but the precise nature of this coupling remains contentious. Recent research has argued that covert attention and overt eye-movements many share a common biological limit, such t...

Site-Dependent Effects of tDCS Uncover Dissociations in the Communication Network Underlying the Processing of Visual Search (2013)
Journal Article
Ball, K., Lane, A., Smith, D., & Ellison, A. (2013). Site-Dependent Effects of tDCS Uncover Dissociations in the Communication Network Underlying the Processing of Visual Search. Brain Stimulation, 6(6), 959-965. https://doi.org/10.1016/j.brs.2013.06.001

Background: The right posterior parietal cortex (rPPC) and the right frontal eye field (rFEF) form part of a network of brain areas involved in orienting spatial attention. Previous studies using transcranial magnetic stimulation (TMS) have demonstra...

Oculomotor involvement in spatial working memory is task-specific (2013)
Journal Article
Ball, K., Pearson, D., & Smith, D. (2013). Oculomotor involvement in spatial working memory is task-specific. Cognition, 129(2), 439-446. https://doi.org/10.1016/j.cognition.2013.08.006

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. The ability to represent, remember, and manipulate spatial information is known... Read More about Oculomotor involvement in spatial working memory is task-specific.

Near and far space: understanding the neural mechanisms of spatial attention (2013)
Journal Article

Visuospatial neglect is a multicomponent syndrome, and one dissociation reported is between neglect for near (peripersonal) and far (extrapersonal) space. Owing to patient heterogeneity and extensive lesions, it is difficult to determine the precise... Read More about Near and far space: understanding the neural mechanisms of spatial attention.

Inhibition of Return impairs phosphene detection (2012)
Journal Article

Efficient visual exploration requires the ability to select possible target locations via spatial attention and to deselect previously inspected locations via inhibition of return (IOR). Although a great deal is known about the effects of spatial att... Read More about Inhibition of Return impairs phosphene detection.
