    Behavioral and Neural Plasticity of Ocular Motor Control: Changes in Performance and fMRI Activity Following Antisaccade Training.Sharna D. Jamadar, Beth P. Johnson, Meaghan Clough, Gary F. Egan & Joanne Fielding - 2015 - Frontiers in Human Neuroscience 9:160690.
    The antisaccade task provides a model paradigm that sets the inhibition of a reflexively driven behaviour against the volitional control of a goal-directed behaviour. The stability and adaptability of antisaccade performance was investigated in 23 neurologically healthy individuals. Behaviour and brain function were measured using functional magnetic resonance imaging (fMRI) prior to and immediately following two weeks of daily antisaccade training. Participants performed antisaccade trials faster with no change in directional error rate following two weeks of training; however this increased (...)

    The effect of uncertainty on prediction error in the action perception loop.Kelsey Perrykkad, Rebecca P. Lawson, Sharna Jamadar & Jakob Hohwy - 2021 - Cognition 210 (C):104598.
    Among all their sensations, agents need to distinguish between those caused by themselves and those caused by external causes. The ability to infer agency is particularly challenging under conditions of uncertainty. Within the predictive processing framework, this should happen through active control of prediction error that closes the action-perception loop. Here we use a novel, temporally-sensitive, behavioural proxy for prediction error to show that it is minimised most quickly when volatility is high and when participants report agency, regardless of the (...)
