Meta-analysis of real-time fMRI neurofeedback studies using individual participant data: How is brain regulation mediated?
2015
An increasing number of studies using real-time fMRI neurofeedback have demonstrated that successful regulation of neural activity is possible in various brain regions. Since these studies focused on the regulated region(s), little is known about the target-independent mechanisms associated with neurofeedback-guided control of brain activation, i.e. the regulating network. While the specificity of the activation during self-regulation is an important factor, no study has effectively determined the network involved in self-regulation in general. In an effort to detect regions that are responsible for the act of brain regulation, we performed a post-hoc analysis of data involving different ta…
Visual mismatch negativity (vMMN): A review and meta-analysis of studies in psychiatric and neurological disorders
2016
The visual mismatch negativity (vMMN) response is an event-related potential (ERP) component, which is automatically elicited by events that violate predictions based on prior events. VMMN experiments use visual stimulus repetition to induce predictions, and vMMN is obtained by subtracting the response to rare unpredicted stimuli from those to frequent stimuli. One increasingly popular interpretation of the mismatch response postulates that vMMN, similar to its auditory counterpart (aMMN), represents a prediction error response generated by cortical mechanisms forming probabilistic representations of sensory signals. Here we discuss the physiological and theoretical basis of vMMN and review…
The Two Dimensions of Narcissistic Personality and Support for the Radical Right: The Role of Right–Wing Authoritarianism, Social Dominance Orientati…
2020
This paper offers an explanation of the link between grandiose narcissism and support for radical right parties. Drawing on representative data of the GESIS Panel ( N = 2827), focusing on support for the German radical right populist party Alternative for Germany in 2016 and treating grandiose narcissism as a two–dimensional concept, it is shown that the effects of grandiose narcissism are indirect rather than direct. The paper also reveals that it is mainly narcissistic rivalry that accounts for radical right party support, whereas narcissistic admiration has a protecting relationship. Finally, our results indicate that the indirect effects of narcissistic rivalry on radical right party s…
Quality Control in 3D Printing: Accuracy Analysis of 3D-Printed Models of Patient-Specific Anatomy
2021
As comparative data on the precision of 3D-printed anatomical models are sparse, the aim of this study was to evaluate the accuracy of 3D-printed models of vascular anatomy generated by two commonly used printing technologies. Thirty-five 3D models of large (aortic, wall thickness of 2 mm, n = 30) and small (coronary, wall thickness of 1.25 mm, n = 5) vessels printed with fused deposition modeling (FDM) (rigid, n = 20) and PolyJet (flexible, n = 15) technology were subjected to high-resolution CT scans. From the resulting DICOM (Digital Imaging and Communications in Medicine) dataset, an STL file was generated and wall thickness as well as surface congruency were compared with the original …
Do you know what you are reading for? Exploring the effects of a task model enhancement on fifth graders' purposeful reading
2021
International audience; Background: Drawing on theories of purposeful reading, this study explored task conditions that support fifth graders' selective reading of documents in order to answer questions. More specifically, we investigated whether promoting students' elaboration of their task model increases task performance. Methods: Participants had to answer series of questions by searching documents for the relevant information. Half the participants received a task model prompt, and half received a control prompt. Participants' eye movements were recorded during text search, in order to investigate more precisely the effect of an enhanced task model. Results: Participants provided more …
Adaptive Number Knowledge in Secondary School Students: Profiles and Antecedents
2019
Cited By :1 Export Date: 10 February 2021 Correspondence Address: McMullen, J.; Department of Teacher EducationFinland; email: jake.mcmullen@utu.fi The present study aims to examine inter-individual differences in adaptive number knowledge in secondary school students. Adaptive number knowledge is defined as a well-connected network of knowledge of numerical characteristics and arithmetic relations. Substantial and relevant qualitative differences in the strategies and expression of adaptive number knowledge have been found in primary school students still in the process of learning arithmetic. We present a study involving 879 seventh-grade students that examines the structure of individual…
Literacy programs efficacy for developing children’s early reading skills in familiar language in Zambia
2018
This study investigated the comparative efficacy of a phonics-based reading program and a language experience approach based literacy program to develop reading skills among Zambian early childhood school learners. The learners (n = 1 986; Grade 2 level; females = 50.1%) took either the phonics-based reading program (n = 1 593) or the alternative language experience approach based program (n = 393). They were all assessed for reading skills utilising the Early Grade Reading Assessment test (EGRA) in four languages (Cinyanja, Icibemba, Kiikaonde, and Silozi). Results suggest that learners in phonics-based literacy program were significantly better in letter-sound knowledge in all the four la…
Musical training predicts cerebello-hippocampal coupling during music listening.
2018
Cerebello-hippocampal interactions occur during accurate spatiotemporal prediction of movements. In the context of music listening, differences in cerebello-hippocampal functional connectivity may result from differences in predictive listening accuracy. Using functional MRI, we studied differences in this network between 18 musicians and 18 nonmusicians while they listened to music. Musicians possess a predictive listening advantage over nonmusicians, facilitated by strengthened coupling between produced and heard sounds through lifelong musical experience. Thus, we hypothesized that musicians would exhibit greater functional connectivity than nonmusicians as a marker of accurate online pr…
Implementation of the ROD Crate DAQ Software for the ATLAS Tile Calorimeter and a Search for a MSSM Higgs Boson decaying into Tau pairs
2010
The ATLAS experiment of the LHC at CERN started its operation in 2009. The ROD Crate DAQ (RCD) as a part of the Trigger and Data Acquisition system (TDAQ) is responsible for the operation of the sub-‐detector specific hardware at the level of the back-‐end electronics crates. The RCD for the Tile Calorimeter is fully implemented. In first place, the specific Tile hardware and software is described in the configuration database. In second place, the various plug-‐ins for the RCD that make use of sophisticated programming techniques are characterized. The RCD performance can be evaluated in terms of global DAQ efficiency, which is over 94% for the considered period in 2010 and in terms of …
Does dietary salt induce autoimmunity?
2013
Two recent publications suggest that dietary salt may polarize TH17 cells and therefore increase the risk of developing autoimmune disease. Where low salt diets can readily be tested for their therapeutic effects in autoimmune disease, more work is needed to connect dietary salts with the development of immunopathology.
