Abstract

Humans need to monitor their actions continuously to detect errors as fast as possible and to adjust their performance to prevent future errors. This process of action monitoring can be investigated by measuring the error-related negativity (ERN), an ERP component elicited immediately after an error. In the current study, we investigated action monitoring after administration of the classic antipsychotic haloperidol (2.5 mg), the atypical antipsychotic olanzapine (10 mg), and the antidepressant paroxetine (20 mg), a selective serotonin reuptake inhibitor. Healthy volunteers (N = 14) were administered the three compounds and placebo in a randomized, double-blind, single-dose, four-way cross-over design. All participants performed a speeded two-choice reaction task, while event-related potentials and behavioral measurements were obtained. Both haloperidol and olanzapine significantly reduced ERN amplitudes. After paroxetine, the ERN was not different from placebo. N2 congruency effects were not affected by treatment condition. Only olanzapine demonstrated behavioral effects, namely a slowing of responses, an increase in error rates, and the absence of performance adjustments. The attenuated ERNs after the dopamine antagonist haloperidol are in line with the presumed role of dopamine in action monitoring. Haloperidol is thought to block dopaminergic signaling, thus reducing ERN amplitudes. On the other hand, the effects of olanzapine are mainly caused by its sedative side effect…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
