Sex and cognitive influence on visual hemifield superiority for face and letter recognition
No full textTwo groups of field independent individuals (one male and one female) and two groups of field dependent individuals (one male and one female) were selected as subjects in the experiment. The classification of field dependence-independence was based on predetermined RFT and EFT standards. The subjects, all right-handed, were given a face and a letter recognition task in a tachistoscopic visual hemifield paradigm; reaction time with either hand was the dependent measure. Field independent subjects of both sexes showed a clear right-field superiority for letter and a left-field superiority for face recognition. Field dependent subjects of both sexes showed a right-field superiority in both letter and face recognition, although of a smaller magnitude than the previous group. The results of the experiment do not support previous findings of no field superiority in females for face recognition; on the contrary, they provide additional evidence that measures of cognitive style significantly predict hemisperic specialization
The independence of face identity and facial expression recognition mechanisms: Relationship to sex and cognitive style
No full textTwo tasks, one mapping the recognition of unfamiliar face identity and the other the identification of six facial expressions were unilaterally presented to field dependent and field independent individuals of both genders. Regardless of sex, field independent subjects showed faster response times (RTs) in the left visual vield (LVF) for face identity and for the identification of disgust and fear and faster RTs in the RVF for the identification of anger. A trend toward LVF superiority was found over the whole sample for the facial expression task; this effect was still present when the face identity task was partialled out, indicating the independence of the underlying mechanisms. © 1983
Hemispheric superiorities on a unilateral tactile test: relationship to cognitive dimensions.
No full textSubjects, 30 male and 30 female, were administered a unilateral tactile test, which requires the subject to judge line orientations. More field-independent individuals in the sample perceived line orientation significantly more accurately with their left hand than with their right hand, while more field-dependent individuals showed no significant lateral difference. However, a similar pattern was observed when a verbal comprehension measure was used as a criterion. The results are discussed as they relate to the hypothesis of a link between psychological differentiation and cerebral specialization
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
