No full textIn this conceptual contribution, we argue that experimental investigations of phenomena in the cognitive sciences and consciousness research may benefit from a thorough integration of data acquired from the first-person perspective. We present a line of research from our lab applying this approach to the Libet task on voluntary action. In this well-known experimental paradigm, participants perform a movement at a moment of their own choice. Previous research has shown that this voluntary decision to perform the action is preceded by a specific pattern in the electroencephalogram, the so-called readiness potential. This finding that the decision is preceded (and presumably determined) by an action-related brain processes puts the neuroscientific account at odds with our subjective intuition and challenges the notion of free will. This discrepancy exemplifies the gap between neuro-cognitive models of the mind and the accounts of our conscious experience. The aim of our theoretical proposal is to enrich the study of volitional action by integrating reports from the first-person perspective with the Libet paradigm to develop a more coherent account. This provides an example of implementing the research program of neurophenomenology developed by Francisco Varela to overcome the gap between scientific accounts of the mind and subjective experience. Specifically, we show how this can be achieved by interweaving three methodological approaches: (i) adapting common neuro-cognitive paradigms (i.e., the Libet task); (ii) employing refined first-person methods such as the micro-phenomenological interview; and (iii) collaborating with experienced meditators as research participants. Our contribution demonstrates how the neurophenomenological framework can be used to shed new light on long-standing and fundamental debates in consciousness research. We show that this approach not only addresses questions of intellectual curiosity but also has concrete ethical implications for the practice of science itself, self-determination, and the accountability of the conscious subject. On the basis of our approach, meditation can be seen as a method for enhancing self-regulation and self-determination, which allows for more deliberate decisions and thus more ethical behavior
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
App‐based mindfulness meditation reduces perceived stress and improves self‐regulation in working university students: A randomised controlled trial
No full textWe investigated whether a brief mindfulness meditation programme delivered via a smartphone app improves perceived stress, self‐regulation and life satisfaction in part‐time working university students. Mindfulness and cognitive reappraisal were analysed as potential mediators. A total of 64 university students working at least 20 h per week during the semester were randomised to either a mindfulness‐based mobile intervention or a wait‐list control condition. Participants in the intervention group were asked to complete one training session of 10–15 min per day using the app. Psychological measures were assessed via a self‐report questionnaire at baseline and after 8 weeks. The online mindfulness programme was found to significantly decrease perceived stress (η ( p ) ( 2 ) = .180, a large effect). It also increased self‐regulation (η ( p ) ( 2 ) = .195, a large effect), mindfulness (η ( p ) ( 2 ) = .174; a large effect) and cognitive reappraisal (η ( p ) ( 2 ) = .136, a medium effect). Increments in life satisfaction were not significant. Changes in self‐regulation were mediated by increased mindfulness. Overall, the mobile application was effective in improving mental well‐being and coping abilities in a non‐clinical sample, encouraging further development of digital health treatments
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
