Journal Article

The DLPFC is thought to be critically involved in maintaining attention away from behaviourally irrelevant information, and in the establishment of attentional control settings. These play an important role in the phenomenon of top-down bias to featu... Read More about The Role of the Left Dorsolateral Prefrontal Cortex in Attentional Bias.

The Limitations of Reward Effects on Saccade Latencies: An Exploration of Task-Specificity and Strength (2019)
Journal Article

Saccadic eye movements are simple, visually guided actions. Operant conditioning of specific saccade directions can reduce the latency of eye movements in the conditioned direction. However, it is not clear to what extent this learning transfers from... Read More about The Limitations of Reward Effects on Saccade Latencies: An Exploration of Task-Specificity and Strength.

Light social drinkers are more distracted by irrelevant information from an induced attentional bias than heavy social drinkers (2018)
Journal Article

It is well established that alcoholics and heavy social drinkers show a bias of attention towards alcohol-related items. Previous research suggests that there is a shared foundation of attentional bias, which is linked to attentional control settings...

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 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...

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)

Attention mediates access of sensory events to higher cognitive systems and can be driven by either top-down voluntary mechanisms or in a bottom-up, reflexive fashion by the sensory properties of a stimulus. The exact mechanisms underlying these diff... Read More about Deficits of reflexive attention induced by abduction of the eye.
