Embodied and Grounded Cognition
No full textIn the last 10-15 years, the “embodied” and “grounded” cognition approach has become widespread in all fields related to cognitive science, such as cognitive and social psychology, neuroscience, philosophy, anthropology, computational modelling and robotics. According to this approach, our cognitive activity is grounded in sensorymotor processes and situated in specific contexts and situations. Therefore, in this view, concepts consist of the reactivation of the same neural pattern that is present when
we perceive and/or interact with the objects they refer to. In the same way, understanding language would imply forming a mental simulation of what is linguistically described. This simulation would entail the recruitment of the same neurons that are activated when actually acting or perceiving the situation, action, emotion, object or entity described by language. In the last years a lot of evidence has been collected in favour of EC and GC view.
The aim of this Research Topic is twofold. First, it intends to give an idea of the field of embodied and grounded cognition in its broadness. We therefore intend to invite scientists of
different disciplines (anthropology, philosophy, linguistics, cognitive and social psychology, neuroscience, computer science) to submit their proposals.
The second aim of this Research Topicis to focus on some challenges that in our opinion embodied and grounded theories of cognition need to face. First, we believe that one important challenge for EC and GC views is to account for the way the so-called “abstract concepts” and abstract words are represented. Evidence on the representation of concrete concepts and words is compelling, whereas evidence on abstract concepts representation is still too scarce and limited to restricted domains. We therefore welcome proposals dealing with this complex issue.
Second, we think that embodied and grounded theories of cognition would need to formulate more precise hypotheses, and that in general within the field a larger theoretical effort should
be made. It is striking that, even if a lot of work in the field of computational modelling and robotics starts from an embodied approach, experimental and modelling work on embodied
cognition remain somehow separate. We therefore invite researchers to submit papers proposing models which might help to explain phenomena as well as to constrain and specify
in more detail the predictions and the claims advanced within the framework of EC and GC theories
Introduction to the special topic embodied and grounded cognition
Get PDFIntroduction: In the last 10–15 years, the embodied and
grounded (E and G) cognition approach
has become widespread in all fields related
to cognitive (neuro) science, and a lot of
evidence has been collected. The approach
proposes that cognitive activity is grounded
in sensory–motor processes and situated in
specific contexts and situations.
This special topic had two aims: first,
give an idea of the field in its broadness.
Second, focus on some challenges for E and
G theories. The first important challenge is
to account for understanding abstract concepts
and words. Evidence on the representation
of concrete concepts is compelling,
whereas evidence on abstract concepts is still
scarce and limited to restricted domains. A
second important challenge concerns the
role of computational models. E and G
theories of cognition need to formulate
more precise hypotheses, and models help
to constrain and specify in more detail the
predictions and the claims advanced
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
