The use of physiological, anthropometric, and skill data to predict selection in a talent-identified junior volleyball squad

The aim of this study was to determine whether physiological, anthropometric, and skill test results could discriminate between junior volleyball players of varying ability. Twenty-eight junior volleyball players competed for selection in a talent-identification volleyball programme. Participants underwent measurements of stature, standing reach stature, body mass, skinfold thickness, overhead medicine ball throw, vertical jump, spike jump, 5-m and 10-m speed, "T" test agility, maximal aerobic power, and passing, setting, serving, and spiking technique and accuracy. A discriminant analysis was conducted on the selected and non-selected groups to obtain a regression equation that could be used to predict selection in junior volleyball squads based on the dependent variables. Passing and serving technique were the only significant variables included in the discriminant analysis. Cross-validation results showed that 17 of 19 selected players (89.5%) and 5 of 9 non-selected players (55.6%) were correctly classified into selected and non-selected groups, respectively, providing an overall predictive accuracy of 78.6%. The results of this study demonstrate that selected skill test results (i.e. subjective coach evaluations of passing technique and serving technique), but not physiological and anthropometric data, discriminate between successful and unsuccessful talent-identified junior volleyball players. These results demonstrate the importance of developing passing and serving technique in talent-identified junior volleyball players.     

Infant Attachment Security and Early Childhood Behavioral Inhibition Interact to Predict Adolescent Social Anxiety Symptoms

Insecure attachment and behavioral inhibition (BI) increase risk for internalizing problems, but few longitudinal studies have examined their interaction in predicting adolescent anxiety. This study included 165 adolescents (ages 14–17 years) selected based on their reactivity to novelty at 4 months. Infant attachment was assessed with the Strange Situation. Multimethod BI assessments were conducted across childhood. Adolescents and their parents independently reported on anxiety. The interaction of attachment and BI significantly predicted adolescent anxiety symptoms, such that BI and anxiety were only associated among adolescents with histories of insecure attachment. Exploratory analyses revealed that this effect was driven by insecure‐resistant attachment and that the association between BI and social anxiety was significant only for insecure males. Clinical implications are discussed.     

Concurrent and Longitudinal Contributions of a Brief Assessment of Reading‐Specific Executive Function to Reading Comprehension in First and Second Grade Students

Executive function (EF) contributes significantly to reading comprehension across the lifespan. Emerging research indicates domain‐specific assessments of EF are better suited for assessment and intervention in academic contexts. For example, graphophonological‐semantic cognitive flexibility (GSF), the ability to flexibly switch between the graphophonological and semantic components of printed words, contributes uniquely to reading comprehension across the lifespan, and GSF training improves children's reading comprehension. This study compared the original GSF measure, which is problematic for use in schools due to its subjectively interpreted explicit explanation component, to an abbreviated implicit task that is better suited for assessment of GSF in practical contexts in 68 first and second grade students. Implicit and explicit GSF contributed uniquely to reading comprehension concurrently and longitudinally when children (n = 31) were in third and fourth grades, beyond verbal ability, decoding ability, and matrix reasoning.     

How to unring the bell: A meta-analytic approach to correction of misinformation

The study reports on a meta-analysis of attempts to correct misinformation (k?=?65). Results indicate that corrective messages have a moderate influence on belief in misinformation (r?=?.35); however, it is more difficult to correct for misinformation in the context of politics (r?=?.15) and marketing (r?=?.18) than health (r?=?.27). Correction of real-world misinformation is more challenging (r?=?.14), as opposed to constructed misinformation (r?=?.48). Rebuttals (r?=?.38) are more effective than forewarnings (r?=?.16), and appeals to coherence (r?=?.55) outperform fact-checking (r?=?.25), and appeals to credibility (r?=?.14).     

Cognitive styles and reading performance

Conclusion The cognitive style-reading connection appears to represent a case of promises not yet fulfilled. Further, it is dubious whether fulfillment is just around the corner. Certainly, one can question the one-cognitive-style-at-a-time approach that has been dominant thus far. The time may have come to think about cognitive styles along with other cognitive measures in combination. Multiple-regression and other multivariate techniques are clearly called for. Without any doubt, the Cronbach-Snow (1977) ATI approach deserves further consideration, not only in the sense of matching styles with instructional treatments in reading — what is called the capitalization approach — but also in the sense of devising methods that can serve a prosthetic function to overcome styles that are maladaptive for reading — a compensatory approach, in other words. The foregoing theme as well as others scattered through the paper could potentially be developed into systematic research proposals aiming to bridge the domains of cognitive style and reading performance. Loose ends abound in the present area, and much progress is possible if energy and imagination are applied to the task. It is my hope that this state-of-the-art article offers a modest step in that direction. This paper was presented as part of the Symposium on Cognitive Processes and Strategies in Reading at the 30th Annual Conference of the Orton Society, Indianapolis, November 1979.     

Language choice for science education: policy and practice

The Maltese National Minimum Curriculum published in 1999 sought to strengthen bilingualism by reinforcing the practice of teaching and assessing some subjects in English and others in Maltese. It also pointed out that code-switching should only be used in cases of severe pedagogical difficulties. As a new National Curriculum Framework was being prepared some educators suggested language as a possible barrier to student progress and argued that the traditional practice of teaching subjects such as science in English should be reconsidered. This study investigated language choices, function and code-switching in science lessons. Classroom observations, interviews and focus groups showed that in state schools 12-13 year old students were being taught science predominantly in Maltese while reading, writing and formal assessment were in English. Students who were more exposed to English, irrespective of class stream, used this language more frequently than those who were less exposed to the language. The findings seem to suggest that teachers may be overcautious. While code-switching may initially provide technical terms and serve as a bridge between the two languages, eventually it can give way to a more precise and formal use of English thus ensuring both learning of science and development of bilingualism.     

Each Medium Tells a Different Story: The Effect of Message Channel on Narrative Persuasion

Limited attention has been given to the medium of story presentation in this process of narrative persuasion. The present study (N = 243) fills this gap by directly comparing narrative involvement across print and audiovisual versions of the same cervical cancer-related story. The mediation analysis revealed that exposure to an audiovisual narrative was associated with higher levels of cognitive and emotional involvement than exposure to the exact same narrative in its printed form. Yet the higher levels of transportation in the audiovisual condition came at a price of enhancing psychological reactance, eliminating the relative advantage of the film narrative.
