    Volker Thoma

    Professor of Cognitive Psychology

    My research focuses on the cognitive and neural mechanisms underlying cognitive control, judgment and decision-making, particularly in behavioural addictions such as gambling and problematic social media use. A major strand of my work uses non-invasive brain stimulation, especially transcranial direct current stimulation (tDCS), to examine the role of prefrontal brain regions in inhibitory control, reflective thinking and reward regulation. I investigate whether stimulating the dorsolateral prefrontal cortex can strengthen cognitive control and reduce impulsive decision-making. My research combines behavioural experiments with EEG, event-related potentials (ERPs) and eye-tracking to examine neural and attentional processes. The long-term aim is to develop theoretically informed interventions for behavioural addiction and problematic reward-seeking behaviour.
