Test świadomego myślenia – heurystyki, religia, płeć
Get PDFThe aim of the article is to describe the phenomena of the cognitive reflection test which is a unique predictor and actual measure of rational thought. The CRT is designed to measure the tendency to override a prepotent response alternative that is incorrect and to engage in further reflection that leads to correct response. The author describes also the correlation between CRT and heuristics and the influence of religion and sex on CRT results.Artykuł wprowadza w tematykę automatycznych i kontrolowanych procesów myślenia. Autorka opisuje test świadomego myślenia (Cognitive Reflection Test – CRT), który – jak pokazuje literatura z zakresu finansów behawioralnych – jest świetnym narzędziem sprawdzającym zdolność jednostek do myślenia racjonalnego. W opracowaniu przedstawiono również badania opisujące zależność pomiędzy wynikami z testu CRT a skłonnością do ulegania heurystykom oraz wpływ myślenia intuicyjnego na religię i płeć
The exploration of disposition effect among business undergraduates in Poland
Get PDFIn this article the author attempts to explore the phenomena of disposition effect among Polish undergraduate students. The study shows that under experimental conditions participants do show disposition “to sell winners too early and ride losers too long”. Such disposition stands in opposition to rationale behavior which induces to hold stocks during the whole period of experiment. The research provides important insights into the field of behavioral finance and in particular into the global analysis of disposition effect.</p
Loss aversion and behavioral heuristics and biases in cultural dimension
No full textArtykuł wprowadza w problematykę finansów kulturowych, które zakładają
że jednostki wywodzące się z różnych kultur w różny sposób postrzegają rzeczywistość, co
w rezultacie przekłada się na odmienne zachowania w kontekście podejmowania decyzji
ekonomicznych. Okazuje się, że region kulturowy, z którego wywodzi się jednostka, ma
również wpływ na stopień ulegania heurystykom opisanym przez literaturę z zakresu finansów
behawioralnych. Celem artykułu jest pokazanie, że istnieją różnice w poziomie
ulegania poszczególnym heurystykom w zależności od kręgu kulturowego, z którego wywodzi
się dana osoba.
Wyniki przeprowadzonych analiz na grupach studentów pochodzących z Indii, Stanów
Zjednoczonych i Polski wskazują na różnice w zakresie awersji do strat oraz w stopniu
ulegania heurystyce zakotwiczenia i nadmiernej pewności siebie pomiędzy grupami
badanych respondentów.The aim of the article is to present a cultural approach in finance. Cultural
finance aims to integrate cultural aspects into the analysis of financial questions. It turns
out that culture impacts investor behavior and their reliance on cognitive biases and heuristics
described by behavioral finance literature. Author combines the behavioral and
cultural approach in finance and investigate three groups of students coming from India,
United States and Poland. Study shows that there are significant differences among analyzed
groups in levels of overconfidence (overprecision and overplacement), anchoring
bias, loss aversion
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
Anchoring and Overconfidence: The Influence of Culture and Cognitive Abilities
No full textAnchoring and overconfidence are some of the best-known biases in psychology and behavioral finance literature. While a number of studies have investigated the evidence of these biases and explored the motives and human factors that contribute to the one’s susceptibility to the effects, little is known about the cultural factors behind these heuristic biases. This paper aims to fill the research gap and shows the differences in proneness to the anchoring effect and overconfidence in two samples of students from Poland and India. The purpose of the study is twofold: to analyze susceptibility to behavioral effects relative to cultural background; and to consider the subjects’ cognitive abilities as a potential factor in their exposure to behavioral biases and confirm that subjects with higher cognitive skills, measured by the cognitive reflection test (CRT) display less susceptibility to the above heuristic biases
