Schizophrenia and automatic processing: an exploratory study.
1991
This study deals with the schizophrenic deficit as one of automatic processing. To test the idea, a special experimental task was designed on which 21 schizophrenics, 21 depressives, and 21 normal subjects had to complete a series of simple geometric figures. When the subjects had thoroughly learned this activity, another information source, a brief story, was introduced, and the subjects had to pay attention to the story while they did the task. Two dependent variables were considered, execution time and performance. There were no differences among the three groups in the first experimental condition; but in the second condition, when the distractor was introduced, schizophrenics needed m…
Evidence for gesture-speech mismatch detection impairments in schizophrenia.
2019
Patients with schizophrenia suffer from impairments in the perception and production of gestures. The extent to which patients can access the semantic association between speech and co-verbal gestures in concrete or abstract/metaphorical meaning contexts is unknown. We investigated 1) how patients differ from controls in gesture matching performance, 2) how performance differs in the context of abstract versus concrete meaning, and 3) whether formal thought disorder (FTD) symptom severity predicts task impairment. Forty-five patients with schizophrenia spectrum disorders (two subgroups, mild and severe) took part in this study. Participants were presented with video clips, each showing an a…
Why have I failed? Why have I passed? A comparison of students’ causal attributions in second language acquisition (A1–B2 levels)
2019
Background Previous literature highlights the importance of causal attributions in achievement and motivation. However, the studies about causal attributions in second language acquisition (SLA) are limited and scarce. Aims This study was designed to determine the frequency of successful and unsuccessful activities per English level and to compare the causal attributions (explanations of outcomes) on successful and failure authentic tasks undertaken in the context of learning English as a foreign language (EFL) acquisition in an Official School of Languages (OSL). Sample To this aim, 407 native Spanish students from levels A1 (n = 111), A2 (n = 113), B1 (n = 98), and B2 (n = 85) in OSL part…
Visual Search for Grouped versus Ungrouped Icons in a Computer Interface
2000
The paradigm of visual search was used to investigate how participants looked for a target file among distracter files in an icon-based computer interface. The purpose of these experiments was to study the effect of icons and spatial grouping on scanning speed. Does spatial grouping of identical icons increase the scanning speed? Do icons themselves speed up the search for a target file when compared with a condition in which the files are indicated with mere textual labels? Our results showed that both the presence of icons and their grouping had a significant positive effect on the scanning speed. Potential applications of this research include the design of graphics-based interfaces, su…
Model order effects on ICA of resting-state complex-valued fMRI data : application to schizophrenia
2018
Abstract Background Component splitting at higher model orders is a widely accepted finding for independent component analysis (ICA) of functional magnetic resonance imaging (fMRI) data. However, our recent study found that intact components occurred with subcomponents at higher model orders. New method This study investigated model order effects on ICA of resting-state complex-valued fMRI data from 82 subjects, which included 40 healthy controls (HCs) and 42 schizophrenia patients. In addition, we explored underlying causes for distinct component splitting between complex-valued data and magnitude-only data by examining model order effects on ICA of phase fMRI data. A best run selection me…
Visuospatial processing in schizophrenia: Does it share common mechanisms with pseudoneglect?
2011
International audience; ''Schizophrenia patients demonstrate behavioural and cerebral lateralised anomalies, prompting some authors to suggest they exhibit a mild form of right unilateral neglect. To better describe and understand lateralised visuospatial anomalies in schizophrenia, three experiments were run using tasks often utilised to study visuospatial processing in healthy individuals and in neglect patients: the Behavioural Inattention Test (BIT), the manual line bisection task with and without a local cueing paradigm, the landmark task (or line bisection judgement), and the number bisection task. Although the schizophrenia patients did not exhibit the full-blown neglect syndrome, th…

Evaluation of the Possible Impact of a Care Network for Stroke and Transient Ischemic Attack on Rates of Recurrence
2010
We aimed to demonstrate that a stroke network is able to reduce the proportion of recurrent cerebrovascular events. In 2003, we set up a care network with the aim to reduce the proportion of stroke recurrence. For the statistical analysis, recurrent cerebrovascular events observed from 1985 to 2002 within the population of Dijon made it possible to model trends using Poisson logistic regression. From 1985 to 2002, we recorded 172 recurrent cerebrovascular events which were used to model trends before the creation of the care network. Within the period 2003–2007, we observed 162 recurrent cerebrovascular events compared with 196.7 expected cerebrovascular events with a significant standardiz…
Auditory Mismatch Negativity and Repetition Suppression Deficits in Schizophrenia Explained by Irregular Computation of Prediction Error
2015
Background The predictive coding model is rapidly gaining attention in schizophrenia research. It posits the neuronal computation of residual variance (‘prediction error’) between sensory information and top-down expectation through multiple hierarchical levels. Event-related potentials (ERP) reflect cortical processing stages that are increasingly interpreted in the light of the predictive coding hypothesis. Both mismatch negativity (MMN) and repetition suppression (RS) measures are considered a prediction error correlates based on error detection and error minimization, respectively. Methods Twenty-five schizophrenia patients and 25 healthy controls completed auditory tasks designed to el…
Improving Quality of Care in Inflammatory Bowel Disease Through Patients’ Eyes: IQCARO Project
2019
Abstract Background Quality improvement is a major topic in inflammatory bowel disease (IBD) care, and measuring quality of care (QoC) is necessary for QoC improvement. Most QoC projects or consensus statements are designed from the health care professional point of view. Having QoC indicators designed for and fully evaluable by patients may provide a key tool for external evaluation of QoC improvement measures. The aim of the IQCARO project was to identify indicators to measure QoC from the IBD patient’s point of view. Methods An extensive review of the literature to identify indicators of QoC was performed; first the identified indicators were reviewed by a steering committee including pa…
