An overview of quantitative approaches in Gestalt perception
Gestalt psychology is often criticized as lacking quantitative measurements and precise mathematical models. While this is true of the early Gestalt school, today there are many quantitative approaches in Gestalt perception and the special issue of Vision ...
Elsevier2016Influence of MCHR2 and MCHR2-AS1 Genetic Polymorphisms on Body Mass Index in Psychiatric Patients and In Population-Based Subjects with Present or Past Atypical Depression
Pierre Magistretti, Aurélie Delacrétaz
Obesity development during psychotropic treatments represents a major health issue in psychiatry. Melanin-concentrating hormone receptor 2 (MCHR2) is a central receptor involved in energy homeostasis. MCHR2 shares its promoter region with MCHR2-AS1, a long ...
Public Library of Science2015Release of crowding by pattern completion
Michael Herzog, Gregory Francis, Mauro Manassi
In crowding, target perception deteriorates in the presence of flanking elements. Crowding is classically explained by low-level mechanisms such as pooling or feature substitution. However, we have previously shown that perceptual grouping between the targ ...
Association for Research in Vision and Ophthalmology2015Regulation of Neurotrophic Factors and Energy Metabolism by Antidepressants in Astrocytes
Pierre Magistretti, Jean-Luc Martin, Igor Allaman
There is growing evidence that astrocytes are involved in the neuropathology of major depression. In particular, decreases in glial cell density observed in the cerebral cortex of individuals with major depressive disorder are accompanied by a reduction of ...
Bentham Science Publishers2013Crowding and grouping: how much time is needed to process good Gestalt?
In crowding, perception of a target is deteriorated by flanking elements. Crowding is usually explained by pooling models where target and flanker signals are averaged. We show here that crowding is rather determined by grouping and good Gestalt. We determ ...
2013Inferring 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, ...
Wiley-Blackwell2013Schizophrenia and visual backward masking: a general deficit of target enhancement
Michael Herzog, Maya Roinishvili
The obvious symptoms of schizophrenia are of cognitive and psychopathological nature. However, schizophrenia affects also visual processing which becomes particularly evident when stimuli are presented for short durations and are followed by a masking stim ...
Frontiers Research Foundation2013Backward masking reveals different visual processing of schizophrenic and depressive patients
Michael Herzog, Maya Roinishvili
Visual backward masking is a very sensitive tool for studying early visual processing deficits and a reliable endophenotype of schizophrenia. Mental diseases strongly overlap in many aspects, for example, in psychopathology, cognition, and genetics. Here, ...
Pion Ltd.2012Patients with functional psychoses show similar visual backward masking deficits
Michael Herzog, Maya Roinishvili
Recent genetic, behavioral, and clinical studies suggest that functional psychoses (schizophrenia, bipolar disorder, schizoaffective disorder), previously thought to be distinct from each other, may belong to one continuum. The shine-through masking paradi ...
Elsevier2012Grouping, pooling, and when bigger is better in visual crowding
Michael Herzog, Bilge Sayim, Mauro Manassi
In crowding, perception of a target is strongly deteriorated by nearby elements. Crowding is often explained by pooling models predicting that adding flankers increases crowding. In contrast, the centroid hypothesis proposes that adding flankers decreases ...
