Evidence of different underlying processes in pattern recall and decision-making
No full textThe visual search characteristics of expert and novice basketball players were recorded during pattern recall and decision-making tasks to determine whether the two tasks shared common visual–perceptual processing strategies. The order in which participants entered the pattern elements in the recall task was also analysed to further examine the nature of the visual–perceptual strategies and the relative emphasis placed upon particular pattern features. The experts demonstrated superior performance across the recall and decision-making tasks (see also Gorman, A. D., Abernethy, B., & Farrow, D. (2012). Classical pattern recall tests and the prospective nature of expert performance. The Quarterly Journal of Experimental Psychology, 65, 1151–1160; Gorman, A. D., Abernethy, B., & Farrow, D. (2013a). Is the relationship between pattern recall and decision-making influenced by anticipatory recall? The Quarterly Journal of Experimental Psychology, 66, 2219–2236) but a number of significant differences in the visual search data highlighted disparities in the processing strategies, suggesting that recall skill may utilize different underlying visual–perceptual processes than those required for accurate decision-making performance in the natural setting. Performance on the recall task was characterized by a proximal-to-distal order of entry of the pattern elements with participants tending to enter the players located closest to the ball carrier earlier than those located more distal to the ball carrier. The results provide further evidence of the underlying perceptual processes employed by experts when extracting visual information from complex and dynamic patterns
Challenges to capturing expertise in field settings
No full textUnderstanding and developing expertise is an important concern for any researcher or practitioner working in elite or high performance sport. Whether it's identifying talented young athletes or developing methods for integrating cutting-edge sport science into daily coaching practice, scientists, coaches and researchers all need to understand the skills, characteristics, and knowledge that distinguish the expert performer in sport. The Routledge Handbook of Sport Expertise is the first book to offer a comprehensive overview of current research and practice in the emerging field of sports expertise. Adopting a multi-disciplinary, multi-faceted approach, the book offers in-depth discussion of methodological and philosophical issues in sport expertise, as well as the characteristics that describe sporting ‘experts’ and how they can be facilitated and developed. Exploring research, theory and practice, the book also examines how scientists and practitioners can work together to improve the delivery of applied sport science. With contributions from many of the world’s leading researchers in expertise and skill acquisition in sport, the Routledge Handbook of Sport Expertise is important reading for any advanced student, researcher, coach or sport science support officer looking to better understand this cutting-edge topic.

Adam und Eva in der byzantinischen und abendländischen Kunst des Mittelalters
No full textThe pictorial art of the Church, as a spiritual product of the Christian civilisation, has continually received great influences from its ecclesiastical tradition and it was defined by its formal aesthetical standards and its iconographic preferences. A more nuanced reading of the parallels can be attained by placing the images in their visual context, which would allow a better appreciation of the meanings within. The biblical story of Adam and Eve, which is the theme of the following thesis, reflects the differentiation between the Eastern and the Western understanding of the events of the history of the holy Oikonomia, a point, which is the major ground for the development of the relative pictorial motifs. The protoplasts are the protagonists from their creation and life in paradise, the fall and expulsion until their resurrection through Christ. Their story is visualised in a number of scenes and episodes, having thus their original sin and resurrection for specific reasons centralised. This doctoral thesis attempts to collect as many parallels of the scenes is possible, trying to collate the Eastern with the Western visual approach in a deductive way, in order to reach our constructive conclusions and make available the combination of the art, theology and liturgy in the scenes of Adam and Eve in Genesis and in Resurrection (Anastasis). The reading we tried to perform was based upon the specific iconographical elements, which were worth to be commented. Our aim was to detect the direct bond between the production of art and the relevant patristic and apocryphal writings or even the theological theories, by quoting texts from the ecclesiastical literature, as well as the liturgical praxis.Die kirchliche Kunst hat als geistiges Produkt der christlichen Kultur stets unter dem Einfluss der kirchlichen Tradition gestanden und wurde durch ihre formalen ästhetischen Standards und ihre ikonographische Auswahl bestimmt. Eine genauere Bestimmung der Parallelen kann erreicht werden, indem man die Bilder in ihren visuellen Kontext stellt, was zu einem besserem Verständnis ihrer Inhalte führt. Die biblische Geschichte von Adam und Eva, welche das Thema unserer Arbeit ist, reflektiert das differenzierte Verständnis der Heilsgeschichte (Oikonomia) in Ost und West, welche die Hauptursache für die Entwicklung der entsprechenden Bildmotive ist. Die Stammeltern sind die Protagonisten dieser Geschichte seit der Schöpfung und dem Leben im Paradies, sowie Sündenfall und Vertreibung, bis zu ihrer Auferweckung durch Christus. Ihre Geschichte wird in einer Reihe von Szenen und Episoden visualisiert, wobei die Ursünde und die Auferstehung aus besonderen Gründen im Mittelpunkt stehen. Diese Dissertation versucht, so viele wie mögliche Gemeinsamkeiten der Darstellung herauszuarbeiten, um so in deduktiver Weise den visuellen Zugang des Ostens und des Westens in Beziehung zu setzen, um zu konstruktiven Ergebnissen zu kommen und eine Verbindung von Kunst, Theologie und Liturgie in den Darstellungen von Adam und Eva in der Genesis und der Anastasis, am Anfang und am Ende also, herzustellen. Unsere Untersuchung basiert auf den spezifischen ikonographischen Elementen, die wir kommentieren. Unser Ziel war es, die unmittelbare Verbindung zwischen der künstlerischen Darstellung und den entsprechenden patristischen oder apokryphen Schriften oder sogar den theologischen Theorien zu ermitteln, indem wir Texte aus der kirchlichen Literatur, aber auch aus der liturgischen Praxis heranzogen. Wir versuchten die Beteiligung der Stammeltern Adam und Eva im Genesis-Zyklus und der Anastasis-Szene in Beziehung zu setzen, deren Darstellungsnormen zur Gänze auf der Heilsverheissung Gottes basieren. So besteht unsere Dissertation aus zwei Teilen: Genesis und Anastasis (Abstieg in den Hades), sowie einem Anhang, welcher die Überschrift „Die Bildsprache der Geschichte der Stammeltern“ trägt, der Bibliographie und einer Liste der verwendeten Abbildungen
Open access self-archiving: An author study
No full textThis, our second author international, cross-disciplinary study on open access had 1296 respondents. Its focus was on self-archiving. Almost half (49%) of the respondent population have self-archived at least one article during the last three years. Use of institutional repositories for this purpose has doubled and usage has increased by almost 60% for subject-based repositories. Self-archiving activity is greatest amongst those who publish the largest number of papers. There is still a substantial proportion of authors unaware of the possibility of providing open access to their work by self-archiving. Of the authors who have not yet self-archived any articles, 71% remain unaware of the option. With 49% of the author population having self-archived in some way, this means that 36% of the total author population (71% of the remaining 51%), has not yet been appraised of this way of providing open access. Authors have frequently expressed reluctance to self-archive because of the perceived time required and possible technical difficulties in carrying out this activity, yet findings here show that only 20% of authors found some degree of difficulty with the first act of depositing an article in a repository, and that this dropped to 9% for subsequent deposits. Another author worry is about infringing agreed copyright agreements with publishers, yet only 10% of authors currently know of the SHERPA/RoMEO list of publisher permissions policies with respect to self-archiving, where clear guidance as to what a publisher permits is provided. Where it is not known if permission is required, however, authors are not seeking it and are self-archiving without it. Communicating their results to peers remains the primary reason for scholars publishing their work; in other words,
researchers publish to have an impact on their field. The vast majority of authors (81%) would willingly comply with a mandate from their employer or research funder to deposit copies of their articles in an institutional or subject-based repository. A further 13% would comply reluctantly; 5% would not comply with such a mandate
Reduced attentional focus and the influence on expert anticipatory perception
No full textThe anticipatory memory encodings of expert and novice basketball players were examined under conditions of both full (attended condition) and reduced (unattended condition) attention (see also Gorman, Abernethy, & Farrow in Attention, Perception, & Psychophysics, 75, 835–844, 2013a). Participants completed a typical pattern recall task using dynamic playing sequences from basketball, and their responses were compared to both the original target pattern as well as to the series of patterns that occurred immediately after and immediately before the target image. The latter had not previously been employed in a pattern recall task when examining the anticipatory encoding of pattern information. Results revealed that the overall extent of the forward displacement for both the attended and unattended patterns was generally significantly greater for the experts, with the expert advantage tending to be most prominent for the attacking patterns. The novel addition of both forward and backward scenes may provide a more precise measure of the anticipatory effect, suggesting that future research in this domain should use a similar methodological design

Meaning and Measurement of Family Comment on Gorman-Smith et al. (1996)
No full textD. Gorman-Smith, P. H. Tolan, A. Zelli, & L. R. Huesmann (1996) highlight important issues for the treatment of conduct problems. Their results suggest that the concept of family and the family treatment of serious delinquency should target two dimensions: parenting practices and family characteristics. Additionally, they raise important questions about the meaning, and hence the measurement, of family. The debate articulated in this comment focuses on whether the family is considered to be a collection of individuals with unique perspectives, a unique whole with its own beliefs and emotions, or both a collection of individuals and a whole. In this article, the author argues that family research can be improved if researchers specify three components of the measurement of family: (a) target of the assessment, (b) method of the assessment, and (c) method of aggregation

When Adam met Rio: conversations on racism, anti-racism and multiculturalism in the Australian Football League and English Premier League
No full textThis article employs a 2013 televised dialogue on racism between two male, minority ethnic, global football stars – Adam Goodes of the Australian Rules code and Rio Ferdinand, an English Premier League player – for a timely, comparative and cross-cultural analysis of issues around race, ethnicity, Indigeneity, and identity, and dominant approaches to anti-racism and multiculturalism within these codes. Prior to the television interview, the Indigenous Goodes had been racially vilified by a 13-year-old female spectator during a match, and subsequently likened toKing Kongby Collingwood president, Eddie McGuire. After an opponent racially slurred his brother during a 2011 match, Ferdinand initiated a protest, followed by many fellow professionals, against the perceived inaction to racism from football authorities by refusing to wear T-shirts promoting the work of anti-racist organization, Kick It Out. The article argues that, despite their differences, dialogue between the two football codes holds the potential for progressive anti-racist policy-making
Perceptual training using explicit and implicit instructional techniques: does it benefit skilled performers?
No full textThis study investigated the efficacy of explicit and implicit perceptual training approaches designed to improve the pattern perception capabilities of skilled basketball players, relative to control and placebo groups. The explicit and implicit groups completed 4 weeks of training using temporally occluded video footage while the placebo group used general visual stimuli. Results from a video-based test showed no significant differences between the four groups after the training intervention, despite large absolute gains by the two experimental groups. After a 14-day retention interval, improvements by the control group suggested that test familiarity may have influenced the retention test results. The transfer data showed that the laboratory-based training failed to elicit a significant change in on-court performance. The results, while not statistically significant, highlight a number of key considerations when attempting to develop perceptual-cognitive abilities in experienced athletes and provide direction for researchers and practitioners when designing similar training approaches
Using constraints to enhance decision-making in team sports
No full textMotor Learning in Practice explores the fundamental processes of motor learning and skill acquisition in sport, and explains how a constraints-led approach can be used to design more effective learning environments for sports practice and performance. Drawing on ecological psychology, the book examines the interaction of personal, environmental and task-specific constraints in the development of motor skills, and then demonstrates how an understanding of those constraints can be applied in a wide range of specific sports and physical activities.
