Two event-related brain potential (ERP) components, the frontocentral feedback-related negativity (FRN) and posterior P300, are key in feedback processing. The FRN typically exhibits greater amplitude response to negative unexpected outcomes, whereas P300 is generally more pronounced for positive outcomes. In an influential ERP study, Hajcak et al., (2005) manipulated outcome valence expectancy a guessing task. They found was larger outcomes regardless of expectancy, valence. These findings...
In patient studies, impairments of sense body ownership have repeatedly been linked to right-hemispheric brain damage. To test whether a dominance for could also be observed in healthy adults, the rubber hand illusion was elicited on both hands 21 left-handers and 22 right-handers. this illusion, participant's real is stroked while hidden from view behind an occluder, nearby visible prosthesis synchrony. Most participants experience illusionary perception touch sensations arising prosthesis....
Abstract Social context influences social decisions and outcome processing, partially depending on inter-individual differences. The present study investigated context-dependent modulation of behavior feedback processing in the ultimatum game (UG) relation to differences anxiety. Thirty-two healthy adults completed UG both under observation without observation. Offers were allegedly either randomly generated by computer or drawn from a pool offers previous human players. Overall, fewer...
Social anxiety disorder (SAD) is a prevalent and disabling mental disorder, associated with significant psychiatric co-morbidity. Previous research on structural brain alterations SAD has yielded inconsistent results concerning the direction of changes in gray matter (GM) various regions, as well relationship between structure SAD-symptomatology. These heterogeneous findings are possibly due to limited sample sizes. Multi-site imaging offers new opportunities investigate SAD-related larger...
Most studies on emotion processing induce emotions through images or films. However, this method lacks ecological validity, limiting generalization to real-life processing. More realistic paradigms using virtual reality (VR) may be better suited investigate authentic emotional states and their neuronal correlates. This pre-registered study examines the underpinnings of naturalistic fear, measured mobile electroencephalography (EEG). Seventy-five healthy participants walked across a plank...
Abstract The present study investigated temporal aspects of cerebellar contributions to the processing performance errors as indexed by error-related negativity (ERN) in response-locked event-related potential (ERP). We co-registered EEG and applied single-pulse transcranial magnetic stimulation (spTMS) left posterolateral cerebellum an extra-cerebellar control region (vertex) while healthy adult volunteers performed a Go/Nogo Flanker Task. In Go trials, TMS pulses were at four different...
Summary Integration of a rubber hand into body representation is intact, which indicates intact multimodal integration despite impaired processing proprioceptive or tactile input in complex regional pain syndrome. In patients with syndrome (CRPS) type 1, static stimuli impaired, whereas more sensory functions appear preserved. This study investigated higher order multisensory body-relevant using the illusion CRPS patients. Subjective self-reports and skin conductance responses to watching...
Abstract Our understanding of altered emotional processing in social anxiety disorder (SAD) is hampered by a heterogeneity findings, which probably due to the vastly different methods and materials used so far. This why present functional magnetic resonance imaging (fMRI) study investigated immediate disorder‐related threat 30 SAD patients healthy controls (HC) with novel, standardized set highly ecologically valid, complex visual scenes. rated as compared neutral scenes more unpleasant,...
Recent rodent data suggest that the cerebellum – a region typically associated with processing sensory prediction errors (PEs) also processes PEs in reinforcement learning (RL-PEs; i.e., from action outcomes). We tested whether cerebellar output is necessary for RL-PE regions more traditionally action-outcome processing, such as striatum and anterior cingulate cortex. The feedback-related negativity (FRN) was measured proxy of cerebral probabilistic feedback task using...
To survive and thrive in our ever-changing environment, we need to be able predict the consequences of actions. We update these predictions by learning through trial error, associated prediction errors (PEs). Recent rodent data suggest that cerebellum – a region typically with processing sensory PEs supervised error-based also processes reinforcement (RL-PEs; i.e., from action outcomes). A proxy outcome regions traditionally RL-PE coding, such as striatum anterior cingulate cortex, can...
Event-related potentials (ERP) research has identified a negative deflection within about 100 to 150 ms after an erroneous response – the error-related negativity (ERN) - as correlate of awareness-independent error processing. The short latency suggests internal monitoring system acting rapidly based on central information such efference copy signal. Studies monkeys and humans have thalamus important relay station for signals ongoing saccades. present study investigated processing...
