Social Cognition in PD
No full textThe aim of this project is to assess the SC construct and to explore its relationship with cognitive state in PD patients.
This dataset include the perfomance of 19 PD patients with cognitive decline, 27 cognitively preserved PD patients and 29 healthy control in social perception (static and dynamic emotional facial recognition), theory of mind, empathy and social behavior tasks. We also assess processing speed, executive functions, memory, language and visuospatial ability. To assess social perception, we administered two emotional categorization tasks, one with 50 static (photograph) and another with 50 dynamic (videos) stimuli, showing facial expressions of happiness, sadness, fear, anger, and neutral face (10 of each emotion) on a computer screen and using the E-prime 2.0 program (Schneider, Eschmann, & Zuccolotto, 2002). To evaluate ToM, we administered the Spanish adaptation of the Reading the Mind in the Eyes Test (RMET; Baron-Cohen et al., 2001). To measure empathy, we used the Empathy Quotient (EQ; Baron-Cohen & Wheelwright, 2004), a self-report measure of empathy. Finally, to assess social behavior, we administered the Spanish version of Dysexecutive Questionnaire (DEX; Shaw, Oei, & Sawang, 2015).</p
Facial expression recognition in MCI
No full textThis projects aims to investigate the ability to recognize emotional facial expressions in MCI individuals compared to healthy elderly and young individuals.
This dataset include the perfomance of 27 MCI individual, 31 healthy elderly and 29 healtthy Young participants using two task: one with static facial expressions (photographs) and another with Dynamic ones (videos). The test procedure has been presented in detail previously (Alonso-Recio et al., 2021). Stimuli were obtained from the Amsterdam Dynamic Facial Expression Set (ADFES; van der Schalk et al., 2011).To describe groups regarding sex, age, depression, anxiety and general cognitive status, we compared sex, age, scores on the spanish version of the Goldberg's Anxiety and depression scale (GADS; Monton et al., 1993) and scores on the Montreal Cognitive Assessment (Nasreddine et al., 2005).</p
Cognitive profile in PD
No full textThe Project was designed to analyze the cognitive heterogeneity in PD patients using a novel data driven approach, the Latent Profile Analysis (LPA), to classify patients according to cognitive characteristics.
This dataset include information about general and specific cognitive perfomance in 71 PD patients without dementia. The neuropsychological battery included different memory and executive function tests. Memory was assessed both for semantic and episodic capabilities. Semantic memory was assessed with a Semantic fluency task (SF; Benton and Hamsher, 1978) and the Boston Naming Test (BNT; Kaplan and Weintraub, 1983). Episodic memory was assessed both with verbal and visuospatial material. Verbal episodic memory was assessed using the Spain-Complutense Verbal Learning Test (Test de Aprendizaje Verbal España-Complutense, TAVEC; Benedet and Alexandre, 1998), and visuospatial episodic memory was assessed using the 7/24 Spatial Recall Test (7/24 SRT; Rao, Hammeke, McQuillen, Khatri, and Lloyd, 1984). Executive function was assessed using the Phonemic Fluency Task (PF; Benton and Hamsher, 1978), the Backward Digit Span of the WAIS-III (BDS; Weschler, 2001) and the Trail Making Test (TMT; Reynolds, 2002). They were selected following the recommendation for neuropsychological evaluation of PD made by the Movement Disorder Society Task Force Guidelines (Litvan et al., 2012).</p
Prediction of cognitive impairment in PD by MoCA
No full textThe aim of this project is to analyze the capacity of the MoCA to detect cognitive impairment in PD, and also to identify anterior and posterior profiles defined by the dual síndrome hypothesis
This dataset include information 59 patients with idiopathic PD were studied with the MoCA and a neuropsychological battery of tests covering all cognitive domains. Tests were selected according to the recommendations of the MDS to assess cognitive impairment in PD patients (Litvan et at., 2012). More specifically, the following processes were assessed: attention/working memory, memory, visuospatial abilities, language and executive functions. Both the MoCA subtests and the neuropsychological tests were grouped according to the two profiles defined by the dual syndrome hypothesis. Hence, a profile was defined for Anterior/attention-executive función and another for Posterior/Memory-Visuospatial impairment.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
