Clocking attention in the human brain
-

University of Oxford, United Kingdom
The temporal dimension is unquestionably fundamental for organizing experience; but has remained largely left out of mainstream attention research. Work in my laboratory seeks to redress this omission by investigating the neural systems and modulatory mechanisms through which temporal expectations influence perception and action. We have demonstrated the ability to orient attention flexibly and voluntarily to the anticipated timing of task-relevant events - effects which have now been replicated by several research groups using different tasks and sensory modalities. In addition, temporal and spatial expectations have been noted to interact strongly to enhance excitability in visual areas, suggesting that temporal expectations may moderate the effects of other top-down biasing signals on neural processing. In the talk, I will illustrate the pervasive effects of temporal expectations on behavioural performance, and review the progress being made in understanding the neural systems and mechanisms involved.
