Numerous studies argue that cortical reorganization may contribute to the restoration of motor function following stroke. However, evolution changes during post-stroke has been little studied. This study sought identify dynamic in functional organization, particularly topological characteristics, execution network stroke recovery process. Ten patients (nine male and one female) with subcortical infarctions were assessed by neurological examination scanned resting-state magnetic resonance...
Objective. Several studies have provided evidence for the claim that a subgroup of (schizophrenic) patients with current delusions share jumping to conclusions (JTC) bias. The primary aim present study was investigate whether currently deluded and non‐deluded schizophrenic perform differently on three tasks tapping probabilistic reasoning. Method. Probabilistic reasoning assessed in 31 patients, 28 psychiatric controls, 17 healthy controls. In addition traditional draws decision procedure,...
Background Altered brain development is evident in children born very preterm (24–32 weeks gestational age), including reduction gray and white matter volumes, thinner cortex, from infancy to adolescence compared term-born peers. However, many questions remain regarding the etiology. Infants are exposed repeated procedural pain-related stress during a period of rapid development. In this vulnerable population, we have previously found that neonatal associated with atypical birth...
A neuropsychological paradigm is introduced that provides a measure of bias against disconfirmatory evidence (BADE), and its correspondence with delusions in people schizophrenia schizoaffective disorder was investigated. Fifty-two patients diagnosed or (36 were acutely delusional) 24 healthy control participants presented delusion-neutral pictures each trial, asked to rate the plausibility four written interpretations scenario depicted by picture. Subsequently, new provided background...
<h3>Background:</h3> Previous schizophrenia research involving the "beads task" has suggested an association between delusions and 2 reasoning biases: (1) "jumping to conclusions" (JTC), whereby early, resolute decisions are formed on basis of little evidence (2) over-adjustment probability estimates following a single instance disconfirmatory evidence. In current study, we used novel JTC-style paradigm provide new information about cognitive operation common these biases. <h3>Methods:</h3>...
Background Although antipsychotic medication still represents the treatment of choice for schizophrenia, its objective impact on symptoms is only in medium-effect size range and at least 50% patients discontinue course treatment. Hence, clinical researchers are intensively looking complementary therapeutic options. Metacognitive training schizophrenia (MCT) a group intervention that seeks to sharpen awareness cognitive biases (e.g. jumping conclusions) seem underlie delusion formation...
Cognitive interventions increasingly complement psychopharmacological treatment to enhance symptomatic and functional outcome in schizophrenia. Metacognitive training (MCT) is targeted at cognitive biases involved the pathogenesis of delusions.To examine long-term efficacy group MCT for schizophrenia order explore whether previously established effects were sustained.A 2-center, randomized, controlled, assessor-blind, parallel trial was conducted. A total 150 inpatients or outpatients with...
The Psychotic Symptom Rating Scales (PSYRATS) is an instrument designed to quantify the severity of delusions and hallucinations typically used in research studies clinical settings focusing on people with psychosis schizophrenia. It comprised auditory (AHS) subscales (DS), but these do not necessarily reflect psychological constructs causing intercorrelation between clusters scale items. Identification important some contexts because item clustering may be caused by underlying etiological...
Background. The present study attempted to extend previous research on source monitoring deficits in schizophrenia. We hypothesized that patients would show a bias attribute self-generated words an external source. Furthermore, it was expected schizophrenic be over-confident regarding false memory attributions. Method. Thirty and 21 healthy participants were instructed provide semantic association for 20 words. Subsequently, list read containing experimenter- as well new subject required...
Previous work has suggested that a bias against disconfirmatory evidence (BADE) may be associated with the schizophrenia spectrum. The current investigation focused on whether BADE (1) overlaps traditional measures of memory and executive functions or selectively taps into unique aspect cognition (2) is correlated delusional ideation but not other aspects schizotypy. Sixty-eight undergraduate students were administered Schizotypal Personality Questionnaire (SPQ), test, Rey Auditory Verbal...
Patients diagnosed with schizophrenia consistently demonstrate impairment in memory acquisition. However, no empirical consensus has been achieved on whether or not patients are more prone to produce false memories.A visual variant of the Deese-Roediger-McDermott (DRM) paradigm was administered 35 and 34 healthy controls. Recognition recognition confidence were later tested for studied lure items. Strong contextual cues at encouraged adoption a gist-based retrieval strategy, which predicted...
