The characteristics of cognitive neuroscience tests in a schizophrenia cognition clinical trial: psychometric properties and correlations with standard measures

In comparison to batteries of standard neuropsychological tests, cognitive neuroscience tests may offer a more specific assessment of discrete neurobiological processes that may be aberrant in schizophrenia. The N-back and AX-Continuous Performance Task (AX-CPT) are two promising cognitive neuroscience tests designed to measure specific components of working memory and contextual processing respectively…read more.

Confidence, performance, and accuracy of self-assessment of social cognition: a comparison of schizophrenia patients and healthy controls

Impairments in self-assessment in schizophrenia have been shown to have functional and clinical implications. Prior studies have suggested that overconfidence can be associated with poorer cognitive performance in people with schizophrenia, and that reduced awareness of performance may be associated with disability…read more.

Depression and reduced emotional experience in schizophrenia: correlations with self-reported and informant rated everyday social functioning

Negative symptoms and depression persist in one third of patients with schizophrenia. Previous studies suggested that depression has more impact on self-perceived compared to observer-rated social functions. Reduced emotional experience, a subdomain of negative symptoms, predicts social functioning deficits, although its role in self-assessment is unclear. We examined depression and reduced emotional experience and self-reports …

Autism symptoms, depression, and active social avoidance in schizophrenia: association with self-reports and informant assessments of everyday functioning

Participants with schizophrenia self-reported their everyday functioning and social cognitive ability as well as their depression. All were rated with the PANSS and a separate rater generated all-sources ratings of everyday functioning and social cognitive ability. Correlations between self-reported everyday functioning and social cognitive ability, ratings of everyday functioning and social cognitive ability, and the …

Predictors of social functioning in patients with higher and lower levels of reduced emotional experience: social cognition, social competence, and symptom severity

Deficits in social functioning in schizophrenia are primarily predicted by negative symptoms, social cognition deficits, and social skills deficits. Here we examine those predictive variables across variations in the severity of reduced emotional experience. We hypothesized that in patients with high symptom severity, factors such as social cognition would have reduced importance for predicting social …

Effects of oxytocin on empathy, introspective accuracy, and social symptoms in schizophrenia: a 12-week twice-daily randomized controlled trial

The effects of intranasal oxytocin, a neuropeptide involved in prosocial behavior and modulation of neural networks underlying social cognition and emotion regulation, have been studied in schizophrenia. We tested the hypothesis that twice-daily intranasal oxytocin administered for 12-weeks would improve tertiary and exploratory outcomes of self-reported social symptoms, empathy and introspective accuracy from the Jarskog …

Targeting reduced neural oscillations in patients with schizophrenia by transcranial alternating current stimulation

Transcranial alternating current stimulation (tACS) modulates endogenous neural oscillations in healthy human participants by the application of a low-amplitude electrical current with a periodic stimulation waveform. Yet, it is unclear if tACS can modulate and restore neural oscillations that are reduced in patients with psychiatric illnesses such as schizophrenia. Here, we asked if tACS modulates …
