Cognitive training with casual video games: the effects of working memory and reasoning related games on the cognitive abilities of younger and older adults
Get PDFCognitive functioning can affect one’s performance at work, quality of life and the ability to live independently, hence there are theoretical and practical implications to understanding whether cognitive training is effective, and its effects across the adult lifespan and with individual differences. There is still mixed evidence to suggest that training on a set of tasks could improve or transfer to other tasks and affect cognitive abilities, in addition to methodological limitations that affect the interpretability of many training studies. In this study, we investigated whether 15 hours of training on casual video games can broadly improve cognition by measuring pre and post-training performance on tests of attention, episodic memory, perceptual speed, reasoning and working memory. Groups of younger (Baniqued et al., 2014) and older adults were trained with casual games that were correlated with working memory and reasoning abilities. Younger adults showed better overall performance and more gains for some games at the end of training compared to the older adults. While all participants improved on the trained games, the pattern of transfer was quite sparse and differed between the younger and older adults. The older adults, unlike the younger adults, did not show differential transfer, as a function of the experimental and an active control group, to a divided attention construct. The results provide evidence that while training gains were possible over the adult lifespan, the transfer to divided attention ability appears to be limited, within the limits of the present study (e.g. given training duration, and the constructs represented in the training games) to the younger adults.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Cher Wee Ang, accepted the attached license on 2016-03-02 at 04:02.The student, Cher Wee Ang, submitted this Dissertation for approval on 2016-03-02 at 04:22.This Dissertation was approved for publication on 2016-03-03 at 14:13.DSpace SAF Submission Ingestion Package generated from Vireo submission #9089 on 2016-07-07 at 13:48:30Made available in DSpace on 2016-07-07T20:26:56Z (GMT).

Training and transfer of training in rapid visual search under high target-background similarity
Get PDFNear-perfect transfer of training was observed in a previous study when participants trained to search for targets on camouflage backgrounds (high target-background similarity) were just as quick to find the camouflaged targets from a different set of images (Boot, Neider & Kramer, 2009). This was achieved in a free viewing paradigm. The unusually robust transfer suggested that participants were learning some general ability to recognize camouflaged targets rather than how each target image stood out against its corresponding background. To explore changes in attentional networks with training in an MRI environment in the future, a paradigm suitable for an fMRI study was tested to determine if the training and transfer benefits remained when using a rapid presentation search paradigm that relies on covert attention. Two groups of participants were tested before and after training, and trained in either camouflage or non-camouflage background conditions. The results showed significant improvements with camouflage training and transfer benefits at the post-training camouflage background test, compared to the control group with non-camouflage training. Both groups were able to use covert attention to detect and recognize camouflaged targets in a brief display, and the camouflage training group transferred this skill to new image set.Item withdrawn by Mark Zulauf ([email protected]) on 2012-12-11T18:59:49Z

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
