Perceptual control theory states that behaviour controls perception; we act against disturbances in the environment to align hierarchically organised perceived aspects of the self and the world with neurally specified reference values. The diverse symptoms of psychopathology are each examples of loss of control, which are maintained by conflicting control systems, and effective interventions shift and sustain awareness to the source of the conflict to allow trial-and-error changes (reorganisation) in the parameters of the superordinate system to the conflict, until control is restored. Experimental, phenomenological, therapeutic and computational research has examined its mechanisms, and its mode of delivery has extended it from a client-led psychotherapy (method of levels) to brief training, group interventions and computerised modalities.

Pre-stimulus oscillatory neural activity has been linked to the level of awareness of sensory stimuli. More specifically, the power of low frequency oscillations (primarily in the alpha-band, i.e. Read More

In multistability, perceptual interpretations ("percepts") of ambiguous stimuli alternate over time. There is considerable debate as to whether similar regularities govern the first percept after stimulus onset and percepts during prolonged presentation. We address this question in a visual pattern-component rivalry paradigm by presenting two overlaid drifting gratings, which participants perceived as individual gratings passing in front of each other ("segregated") or as a plaid ("integrated").

During a flight, pilots must rigorously monitor their flight instruments since it is one of the critical activities that contribute to update their situation awareness. The monitoring is cognitively demanding, but is necessary for timely intervention in the event of a parameter deviation. Many studies have shown that a large part of commercial aviation accidents involved poor cockpit monitoring from the crew. Read More
