Altered Decision Behavior of Dopamine Receptor Knock-out Mice in a Free Binary Choice Task
… important role in updating values according to reward prediction error by reinforcement learning theory, since the finding that phasic activity of midbrain dopamine neurons signals the difference between actual and predicted outcomes (reward prediction error). However, the extent and nature of …

Methodologies and Tools for the Emergence of Cooperation in Biorobotics.
… cognitive architectures, applying them in a reward-based learning mechanism leading to the emergence of cooperation capabilities and perform tasks where one robot alone cannot succeed. The selected technique to induce the emergence of cooperation was based on a selection of specific sub-set …

Motivated Agents
… and decision-making is through reinforcement learning, which relies on external reward-based learning mechanisms to influence the agent’s behavior. While rewards are a primary incentive for learning both in the brain and in machines, recent studies have shown that reward signals in the brain …

Investigating Maladaptive Habit Formation and Threat Influences in Obsessive-Compulsive Disorder
… used to assess the motivational influences of reward-related cues on behaviour. The current state of human appetitive PIT was examined and used as a framework underpinning the acquisition of maladaptive habits. The PIT procedure was then adapted to capture context-dependent threat influences …

Age Differences in Reward Anticipation and Memory
… to that of older adults, research has shown that reward cues can enhance motivated learning and item memory performance of younger adults. In an fMRI study that examined the influence of reward anticipation on episodic memory formation, Adcock and colleagues (2006) examined memory performance in …

Auswirkungen akuten psychosozialen Stresses auf Feedback‐basiertes Lernen
Die Dissertation beschäftigt sich mit der Frage, ob und wie Feedback-basiertes Lernen durch Stress moduliert wird. Der Zusammenhang zwischen Stress und Kognition sowie die zugrunde liegenden biologischen Mechanismen sind Gegenstand der kognitiven Stressforschung. Während der Einfluss von Stress und …
