Systematic review and meta-analysis of the visual mismatch negativity in schizophrenia.

Mismatch negativity (MMN) is an event-related potential component automatically elicited by events that violate predictions based on prior events. To elicit this component, researchers use stimulus repetition to induce predictions, and the MMN is obtained by subtracting the brain response to rare or unpredicted stimuli from that of frequent stimuli. Under the Predictive Processing framework, one increasingly popular interpretation of the mismatch response postulates that MMN represents a prediction error.

Autistic traits and event-related potentials in the general population: A scoping review and meta-analysis.

Background: Differences in short and long-latency Event-Related Potentials (ERPs) can help us infer abnormalities in brain processing, considering early and later stages of stimuli processing across tasks and conditions. In autism research, the adult population remains largely understudied compared to samples at early stages of development. In this context, this scoping review briefly summarises what has been described in community and subclinical adult samples of autism.

Refining the link between psychopathy, antisocial behavior, and empathy: A meta-analytical approach across different conceptual frameworks.

The current meta-analysis includes 477 records (N = 142,692) and comprehensively explores the complex interplay between psychopathy, antisocial behavior, and empathy. First, empathy domains (cognitive and affective) were used to dissociate antisocial behavior from psychopathy. Cognitive empathy was more impaired in antisocial groups (g = -0.

Abnormal Habituation of the Auditory Event-Related Potential P2 Component in Patients With Schizophrenia.

Auditory event-related potentials (ERP) may serve as diagnostic tools for schizophrenia and inform on the susceptibility for this condition. Particularly, the examination of N1 and P2 components of the auditory ERP may shed light on the impairments of information processing streams in schizophrenia. However, the habituation properties (i.

Callousness and meanness traits are associated with increased N2 amplitude in a community sample of adolescents and adults.

The lack of consistent findings in the research field of psychopathy unveils the heterogeneity of this personality structure and, therefore, a dissociation of its phenotypic components is a promising venue to conciliate paradoxical results. The current study aims to assess the dissociable effects of psychopathic traits on N2 and P3 modulation, while analyzing the stability of some endophenotypic processes across development. A sample of adolescents (n = 33) and adults (n = 31) completed, respectively, the Youth Psychopathy Inventory and the Triarchic Psychopathy Measure and performed the same Go/No-Go task during an EEG recording.
