Journal Article
Clinical insight in schizophrenia: Time-specific associations with symptoms, cognition and antipsychotic mechanisms
Background: Impaired clinical insight in schizophrenia is associated with poor treatment adherence and outcomes. Previous research on the influence of symptoms, cognition, and antipsychotic exposure has been inconclusive and restricted to multi-episode samples. We examined time-specific…

No foreign language effect in Schizotypy: Evidence from German-English bilinguals
Previous research has suggested that fewer schizophrenic and schizotypal traits are reported in a second language than a mother tongue. Such results make sense in the light of the so-called Foreign Language Effect (FLE), whereby bilinguals make more rational decisions and are less influenced by…

Journal Article
Unique signatures in verbal fluency task performance in schizophrenia and depression
Background: Verbal fluency tasks reveal consistent impairments among individuals with schizophrenia (SSD) and shed valuable insight on semantic and cognitive processing. However, comparisons with other psychiatric groups remain limited. Doing so may help clarify whether characteristics are unique…

Diagnosis and management of cognitive impairment associated with schizophrenia: Real-world evidence from a cross-sectional survey of psychiatrists
Background: Cognitive impairment is a core feature of schizophrenia that can reduce functional capacity and quality of life in patients. However, it is unclear how physicians approach cognitive impairment associated with schizophrenia (CIAS) in real-world clinical practice. This study examines the…

Journal Article
Psychosis-proneness is associated with reduced cognitive error-monitoring during instrumental learning
Background: People higher in psychosis-proneness tend to resist belief revision despite contradictory evidence, potentially due to impaired error-monitoring. Post-error slowing (PES), one measure of error-monitoring, is linked to working memory (WM) recruitment. With limited WM capacity…

Journal Article
Cognitive deficits in individuals with comorbid personality disorder and schizophrenia: A scoping review
Objective: It is estimated that approximately 40 % of individuals diagnosed with schizophrenia also meet the diagnostic criteria for a personality disorder. This comorbidity is associated with an unfavorable prognosis for the illness. Given that cognition is currently the best predictor of…

Journal Article
Empathic accuracy in individuals at ultra-high risk for psychosis: Using a task with dynamic real-life emotional stimuli
Background: Empathy as a key component of social cognition may be impaired in individuals at ultra-high risk (UHR) for psychosis. The Empathic Accuracy Task (EAT) was designed to address the dynamic and interactive nature of real-world social interactions. This study aimed to examine empathic…

Self-reported cognitive functioning on the behavior rating inventory of executive function in psychotic disorders: Effects of gender, education and cognitive functioning
Introduction: Psychotic disorders (PD) are among the most severe mental disorders and cognitive impairment contributes to this. Few studies have investigated self-reported executive function (srEF)in PD using the Behavior Rating Inventory of Executive Function Adult version (BRIEF-A) and have found…

Journal Article
Call to action on social cognition measures in clinical research
Objective: To describe current practices and key barriers in social cognition (SC) assessment, given its central role in psychiatric and neurological disorders and the limitations of existing measures. Methods: Fifty-two SC experts from 20 countries completed an online survey regarding SC tests and…

Journal Article
Impairments in biological motion perception reflect affective disturbance in individuals at clinical high-risk for psychosis
Background: Social cognitive impairments are common in individuals at clinical high-risk (CHR) for psychosis. Emotion recognition, a key component of social cognition, has been extensively examined in the CHR population, primarily with facial emotion recognition tasks, which have consistently…

Journal Article
Exploring the interplay between language use and cognitive function in schizophrenia spectrum disorders: Insights from patients, first degree relatives, and healthy controls
Background: For people with schizophrenia spectrum disorders (SSD), communication characterized by disrupted language use is common. However, the role of cognitive function in everyday language disruptions in SSD remains unclear. Family studies help control for confounding factors such as symptom…

Journal Article
Theory of mind difficulties in people with social anhedonia: Evidence from behavioural and task-based functional magnetic resonance imaging findings
Background: Social Anhedonia (SA) is recognised as a negative symptom of the schizophrenia spectrum. Despite the emerging evidence of general impairment in Theory of Mind (ToM), the behavioural manifestation and underlying neural mechanisms of ToM deficits in SA remain unclear. The current study…

Journal Article
Visual suppression deficits as a biomarker of working memory impairment in schizophrenia
Introduction: Although working memory (WM) deficits are well established in schizophrenia (SZ), their underlying source is still unclear. It has been proposed that these WM deficits may depend on an imbalance between cortical excitation and inhibition (E/I), but its importance for SZ remains…

Journal Article
Divergent age-related cognitive impairments in first-episode psychosis
Background: Cognitive impairment is a core feature of first-episode psychosis (FEP), but its age-associated cognitive patterns remain unclear. Prior studies suggest FEP is associated with baseline cognitive deficits and accelerated decline, yet inconsistencies exist regarding whether cognitive…

Journal Article
Early versus adult onset of schizophrenia: an examination of premorbid and current IQ
Background: Cognitive deficits are core findings in schizophrenia, but whether the severity of impairments is related to the age of onset remains unclear. We hypothesized that early onset schizophrenia (EOS; onset before age 19) is associated with lower IQ compared to adult-onset schizophrenia…

Journal Article
A clinical control study of modified electroconvulsive therapy and sodium valproate as enhancement strategies for ultra-treatment-resistant schizophrenia
Background: A substantial proportion of patients with schizophrenia show an inadequate response to clozapine, a condition termed ultra-treatment-resistant schizophrenia (UTRS). While modified electroconvulsive therapy (MECT) and sodium valproate are common augmentation strategies, head-to-head…

Journal Article
Premorbid functioning trajectories and the one-year course of cognitive performance in first-episode psychosis: a cluster analysis in PSYSCAN
Background: We examined the course of cognitive performance in first-episode psychosis (FEP) compared to healthy controls (HC), and whether this varied across subgroups of patients defined by premorbid functioning (PMF) trajectories, using a clustering approach. Methods: Data were collected in 302…

Neurocognitive function in schizophrenia spectrum disorders: A 20-year prospective study of a community sample
Longitudinal studies of neurocognition in schizophrenia spectrum disorders (SSD) usually follow relatively young first-episode patients across several years. Comparatively little is known about the neurocognitive trajectory of samples also consisting of older patients. This is a 20-year follow-up…
