A neuroimaging data set on problem solving in the case of the reversal error: Putamen data
Ferrando, Lara; Ventura Campos, Mercedes; Epifanio, Irene Elsevier (2020-09-19)Structural Magnetic Resonance Images (sMRI) for a sample of university students were recorded. Out of magnetic resonance, students performed a test of algebra problem solving. As we are interested in reversal errors, the ... -
Detecting and visualizing differences in brain structures with SPHARM and functional data analysis
Ferrando, Lara; Ventura Campos, Mercedes; Epifanio, Irene Elsevier (2020-08-07)A new procedure for classifying brain structures described by SPHARM is presented. We combine a dimension reduction technique (functional principal component analysis or functional independent component analysis) with ... -
Functional data analysis in shape analysis
Epifanio, Irene; Ventura Campos, Mercedes Elsevier (2011)Mid-level processes on images often return outputs in functional form. In this context the use of functional data analysis (FDA) in image analysis is considered. In particular, attention is focussed on shape analysis, ... -
Hippocampal shape analysis in Alzheimer’s disease using Functional Data Analysis
Epifanio, Irene; Ventura Campos, Mercedes Wiley-Blackwell (2013)The hippocampus is one of the first affected regions in Alzheimer's disease. The left hippocampi of control subjects, patients with mild cognitive impairment and patients with Alzheimer's disease are represented by spherical ... -
Ordinal classification of 3D brain structures by functional data analysis
Ferrando, Lara; Epifanio, Irene; Ventura Campos, Mercedes Elsevier B.V. All (2021-08-24)We introduce several ordinal classification methods for functional data, specificallymultiargument and multivariate functional data. Their performance is analyzed in fourreal data sets that belong to a neuroeducational ... -
The underlying neural bases of the reversal error while solving algebraic word problems
Ventura Campos, Mercedes; Ferrando, Lara; Epifanio, Irene Nature Research (2022)Problem solving is a core element in mathematical learning. The reversal error in problem solving occurs when students are able to recognize the information in the statement of comparison word problems, but they reverse ...
