Research summary

I am interested in understanding attention and cognitive control, and the neural mechanisms underlying these processes.

Several classic tasks in experimental psychology are thought to tap in to our ability to control our behaviour (eg. by withholding a response to a rare stimulus amongst frequent stimuli that require a button press). The ability to control our behaviour is also something that is encountered in day-to-day life and in the media; we often refer to individuals who are less able or likely to control their actions as 'impulsive’. My research is about understanding the way these tasks and abilities relate to each other, as well as understanding what causes people to vary along these dimensions. I use a range of behavioural, statistical, and brain imaging techniques to examine this.

Research topics and related papers

Individual differences and cognitive control

My primary area of research, supervised by Prof. Petroc Sumner, based on understanding the relationship between laboratory based tasks of cognitive control and the concept of  'impulsivity’. In particular, we are interested in how different measures of control relate to each other, how individuals vary in their ability to control their behaviour, and what the neural mechanisms of these differences are.

Selective attention in working memory and perception

Our capacity for maintaining information in a state that is available for report or operation (a state referred to as short-term or working memory) is limited. Similarly, our ability to attend to information in our sensory environment is limited. I am interested in the relationship between these limitations. Specifically, some models of working memory propose that a single item held in memory (eg. a digit or object location) has privileged access for cognitive operations. People are faster to mentally update the location of the same object on two consecutive  steps in a sequence of operations compared to when performing operations on two different objects on consecutive steps. My work has examined whether this state of privileged access is related to perceptual attention, and using a variety of methods (eye-tracking, EEG, statistical modelling) to understand how priority is maintained and modified in working memory.

In addition to these primary areas of research, I am also interested in the application of various methods  to questions in the areas of sensory processing, attention, and memory.
