Cortical beta power reflects decision dynamics and uncovers multiple facets of post-error adaptation (2018)
Journal Article
Fischer, A. G., Nigbur, R., Klein, T. A., Danielmeier, C., & Ullsperger, M. (2018). Cortical beta power reflects decision dynamics and uncovers multiple facets of post-error adaptation. Nature Communications, 9, doi:10.1038/s41467-018-07456-8

Adapting to errors quickly is essential for survival. Reaction slowing after errors is commonly observed but whether this slowing is adaptive or maladaptive is unclear. Here, we analyse a large dataset from a flanker task using two complementary app... Read More

Electrophysiological correlates of error monitoring and feedback processing in second language learning (2017)
Journal Article
Bultena, S., Danielmeier, C., Bekkering, H., & Lemhöfer, K. (2017). Electrophysiological correlates of error monitoring and feedback processing in second language learning. Frontiers in Human Neuroscience, 11(29), doi:10.3389/fnhum.2017.00029. ISSN 1662-5161

Humans monitor their behavior to optimize performance, which presumably relies on stable representations of correct responses. During second language (L2) learning, however, stable representations have yet to be formed while knowledge of the first la... Read More

Gender influences on brain responses to errors and post-error adjustments (2016)
Journal Article
Fischer, A. G., Danielmeier, C., Villringer, A., Klein, T. A., & Ullsperger, M. (2016). Gender influences on brain responses to errors and post-error adjustments. Scientific Reports, 6, doi:10.1038/srep24435

Sexual dimorphisms have been observed in many species, including humans, and extend to the prevalence and presentation of important mental disorders associated with performance monitoring malfunctions. However, precisely which underlying differences... Read More

Reducing speed and sight: how adaptive is post-error slowing? (2016)
Journal Article
Ullsperger, M., & Danielmeier, C. (2016). Reducing speed and sight: how adaptive is post-error slowing?. Neuron, 89(3), doi:10.1016/j.neuron.2016.01.035. ISSN 0896-6273

After errors, humans and monkeys dynamically change decision boundaries which results in posterror slowing of decisions. Simultaneously decreased sensitivity to sensory information counteracts post-error increases in accuracy. Early post-error adjust... Read More

Acetylcholine mediates behavioral and neural post-error control (2015)
Journal Article
Allen, E., Danielmeier, C., Jocham, G., Onur, O., Eichele, T., & Ullsperger, M. (2015). Acetylcholine mediates behavioral and neural post-error control. Current Biology, 25(11), 1461-1468. doi:10.1016/j.cub.2015.04.022

Humans often commit errors when they are distracted by irrelevant information and no longer focus on what is relevant to the task at hand. Adjustments following errors are essential for optimizing goal achievement. The posterior medial frontal cortex... Read More
