Visual backward masking deficits in schizotypy are observed in late but not early onset nicotine smokers

Michael Herzog, Christine Mohr, Guillaume Sierro, Géraldine Beaud

Visual backward masking (VBM) is a potential endophenotype for schizophrenia. Relative VBM deficits were also observed in high as compared to low scorers in one schizotypal subdimension (cognitive disorganisation, CogDis; Cappe et al., 2012). VBM deficits ...

Visual backward masking performance is modulated by sex and schizotypy

Michael Herzog, Christine Mohr, Guillaume Sierro

Deficits in visual backward masking (VBM) may be a stable marker (i.e. endophenotype) of schizophrenia: it is present in patients, their relatives, and healthy individuals (mainly women) scoring high in „cognitive disorganisation” (CD), a schizotypal featu ...

Cognitive disorganisation and Sex affect visual backward masking: data from patients with schizophrenia, non-affected relatives and healthy controls

Michael Herzog, Christine Mohr, Maya Roinishvili, Guillaume Sierro

Endophenotypes (i.e. stable and heritable markers of the illness) are one of the promising tools to understand the pathological mechanisms underlying schizophrenia. We recently showed that deficits in visual backward masking (VBM) meet the criteria for an ...

Visual backward masking deficits are specific to female observers scoring high on cognitive disorganisation

Michael Herzog, Christine Mohr, Guillaume Sierro

Visual backward masking (VBM) deficits are a potential endophenotype of schizophrenia. VBM deficits were found in schizophrenic patients, in their unaffected relatives, and in healthy students scoring high in "cognitive disorganisation" (CD; Cappe et al., ...

Inferring about individual drug and schizotypy effects on cognitive functioning in polydrug using mephedrone users before and after clubbing

Christine Mohr, Daniela Herzig

Objective Mephedrone has been recently made illegal in Europe, but little empirical evidence is available on its impact on human cognitive functions. We investigated acute and chronic effects of mephedrone consumption on drug-sensitive cognitive measures, ...

Visual backward masking deficits in schizotypy

Michael Herzog, Christine Mohr, Ophélie Gladys Favrod

In visual backward masking, a briefly presented target is followed by a mask, which impairs target discrimination. Backward masking is strongly impaired in schizophrenic patients and their unaffected relatives. We found that masking deficits correlated wel ...

Visual backward masking deficits in schizotypy

Michael Herzog, Christine Mohr, Daniela Herzig

Background: In visual backward masking, a target is followed by a mask impeding target perception. Visual backward masking is a potential endophenotype for schizophrenia because patients with schizophrenia and also their unaffected relatives show significa ...

In visual backward masking, a target is followed by a mask impeding target perception. Visual backward masking is a potential endophenotype for schizophrenia because patients with schizophrenia and also their unaffected relatives show significant performan ...

Cognitive disorganisation in schizotypy is associated with deterioration in visual backward masking

Michael Herzog, Christine Mohr, Daniela Herzig

To understand the causes of schizophrenia, a search for stable markers (endophenotypes) is ongoing. In previous years, we have shown that the shine-through visual backward masking paradigm meets the most important characteristics of an endophenotype. Here, ...

Sex moderates the relationship between cognitive disorganisation and visual backward masking: potential implications for an endophenotype of schizophrenia.

Michael Herzog, Christine Mohr, Guillaume Sierro

Schizophrenia is a severe mental disorder that impairs individuals’ life, often chronically and from early adulthood on. There is a search for endophenotypes, i.e. stable markers of the genetic underpinnings of the disease. Visual backward masking (VBM) is ...
