Exploring Guilt Differences in Grandiose Narcissism, Vulnerable Narcissism, and Malignant Self-Regard
No full textNarcissistic personality disorder is a heterogeneous and complex pathology which manifests itself very differently in individuals. The aim of the present study was to analyze differences and similarities in morality and sensitivity to feelings of guilt among grandiose narcissism (GN), vulnerable narcissism (VN), and malignant self-regard (MSR). We expected that MSR and VN would be most sensitive to deontological and altruistic guilt, and that MSR and VN would have higher levels of moral standards than GN. A nonclinical sample of 752 participants was evaluated. Results showed a significant association among MSR, VN, and GN. According to our hypothesis, GN turned out to be the one with the lowest association values to guilt measures. Our results demonstrated that MSR is strongly associated with all types of guilt, GN is associated with a substantial lack of guilt, and VN is associated with deontological guilt and self-hate, but not altruistic guilt. Results confirm the relevance of considering and understanding guilt when differentiating GN, VN, and MSR
Apathy and related Executive Syndromes in Dementia associated with Parkinson’s Disease and in Alzheimer’s Disease
No full textAbstract. Apathy is defined as a lack of motivation and has been reported to be common in Alzheimer’s disease (AD) and
Parkinson’s disease (PD). To explore the neuropsychological correlates of apathy in patients with PD related dementia (PDD)
and AD and to identify the specific cognitive profile of apathy in the two forms of neurodegenerative disease, 61 non-depressed
patients (29 PDD and 32 AD) were selected. Out of these, 29 patients (47.5%) were detected as apathetic (14 PDD-A+ and
15 AD-A+), and 32 patients as non-apathetic (15 PDD-A- and 17 AD-A-). All patients underwent cognitive tasks tapping
memory, visuospatial and executive functions, behavioral rating scales and Clinical Judgment for Apathy Syndrome (CJ-AS), an
inventory developed to measure severity of apathy.
The four subgroups differed significantly on memory and frontal tasks. The PDD-A+ performed significantly worse than PDD-Aon
frontal tasks. The AD-A+ had poorer performance than AD-A- on frontal tasks. Last, PDD-A+ achieved significantly higher
scores than AD-A+ on memory tasks. The four groups differed significantly on CJ-AS and behavioral rating scales.
The results showed that apathetic patients with both forms of dementia showed a common neuropsychological and behavioral
picture, characterized by defects on frontal tasks, thus strongly supporting the existence of an ‘apathetic syndrome’, characterized
by specific cognitive and psychological symptoms
Neural correlates of anosognosia in Alzheimer’s disease and mild cognitive impairment: A multi-method assessment
Get PDFPatients with Alzheimer’s Disease (AD) and Mild Cognitive Impairment (MCI) may present anosognosia for their cognitive deficits. Three different methods have been usually used to measure anosognosia in patients with AD and MCI, but no studies have established if they share similar neuroanatomical correlates. The purpose of this study was to investigate if anosognosia scores obtained with the three most commonly used methods to assess anosognosia relate to focal atrophy in AD and MCI patients, in order to improve understanding of the neural basis of anosognosia in dementia. Anosognosia was evaluated in 27 patients (15 MCI and 12 AD) through clinical rating (Clinical Insight Rating Scale, CIRS), patient-informant discrepancy (Anosognosia Questionnaire Dementia, AQ-D), and performance discrepancy on different cognitive domains (self-appraisal discrepancies, SADs). Voxel-based morphometry correlational analyses were performed on magnetic resonance imaging (MRI) data with each anosognosia score. Increasing anosognosia on any anosognosia measurement (CIRS, AQ-D, SADs) was associated with increasing gray matter atrophy in the medial temporal lobe including the right hippocampus. Our results support a unitary mechanism of anosognosia in AD and MCI, in which medial temporal lobes play a key role, irrespectively of the assessment method used. This is in accordance with models suggesting that anosognosia in AD is primarily caused by a decline in mnemonic processes
A case of progressive frontal lobe syndrome in a sporadic form of Cerebral Amyloid Angiopathy: A singular overlap with fronto-temporal dementia?
No full textGoing 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
