Especial Skills in Experienced Archers

Especial skills are skills that are distinctive by virtue of massive practice within the narrow contexts in which they are expressed. In the first demonstration of especial skills, Keetch, Schmidt, Lee, and Young (2005) showed that experienced basketball players are better at shooting baskets from the foul line, where they had massive amounts of practice, than would expected from their success at other locations closer to or farther from the basket. Similar results were obtained for baseball throwing. The authors asked whether especial skills hold in archery, a sport requiring less movement. If the emergence of especial skills depends on large-scale movement, one would expect archery to escape so-called especialism. But if the emergence of especial skills reflects a more general tendency for highly specific learning, experienced archers should show especial skills. The authors obtained evidence consistent with the latter prediction. The expert archers did much better at their most highly practiced distance than would be expected by looking at the overall function relating shooting score to distance. We offer a mathematical model to account for this result. The findings attest to the generality of the especial skills phenomenon.     

The Factor Structure of the Spiritual Well-Being Scale in Veterans Experienced Chemical Weapon Exposure

This study aimed to determine the factor structure of the spiritual well-being among a sample of the Iranian veterans. In this methodological research, 211 male veterans of Iran–Iraq warfare completed the Paloutzian and Ellison spiritual well-being scale. Maximum likelihood (ML) with oblique rotation was used to assess domain structure of the spiritual well-being. The construct validity of the scale was assessed using confirmatory factor analysis (CFA), convergent validity, and discriminant validity. Reliability was evaluated with Cronbach’s alpha, Theta (θ), and McDonald Omega (Ω) coefficients, intra-class correlation coefficient (ICC), and construct reliability (CR). Results of ML and CFA suggested three factors which were labeled “relationship with God,” “belief in fate and destiny,” and “life optimism.” The ICC, coefficients of the internal consistency, and CR were >.7 for the factors of the scale. Convergent validity and discriminant validity did not fulfill the requirements. The Persian version of spiritual well-being scale demonstrated suitable validity and reliability among the veterans of Iran–Iraq warfare.     

Attachment Style,Perceived Loneliness,and Psychological Well-Being in Smoking and Non-Smoking University Students

The growing rate of smoking cigarettes among the youths necessitates examining its contributing factors. Accordingly, we aimed to compare smoking and nonsmoking university students in their attachment styles, perceived loneliness, and psychological well-being. To this end, we recruited 100 current smokers and 100 nonsmoking students by using a convenience sampling method from Shahid Beheshti University, Tehran, Iran. All participants completed the Adult Attachment Scale, Loneliness Scale, and General Health Questionnaire. Data analysis indicated that compared to nonsmokers, smokers had a more anxious attachment style and they felt lonelier. Moreover, current results showed that smokers suffered from higher rates of psychological problems than nonsmokers. These results suggest that smoking is influenced by a set of psychological factors and therefore, prevention and treatment programs targeting these factors may be effective in reducing the rate of smoking cigarettes among university students.     

Continuing Medical Education: A Cross Sectional Study on a Developing Country’s Perspective

To determine the attitude of general practitioners towards continuing medical education (CME) and reasons motivating or hindering them from attending CME procedures, we conducted a cross-sectional survey from November 2013 to April 2014 in Karachi. Three hundred general practitioners who possessed a medical license for practice in Pakistan filled a pre-designed questionnaire consisting of questions pertaining to attitudes towards CME. Data was entered and analyzed using SPSS v16.0. 70.3% (n = 211) of the participants were males. Mean age was 47.75 ± 9.47 years. Only 67.33% knew about CME and only 52% had attended a CME session. Reasons for attending CME procedures reported were: need for updating knowledge, skills and competencies (67.30%), opportunity to meet colleagues (18.58%) and presenting scientific papers (8.97%). Mean Likert score was 1.67 (±0.667) for those who thought CME is worthwhile and 1.44 (±0.686) for those who consider their clinical duties as the major hurdle in attending CME procedures. Most common cause for not attending CME was lack of knowledge (32.66%) followed by time constraint (24%). Most physicians were not sufficiently informed about the potential benefits of CME and had never attended a CME session. Most common reason for attending CME procedures reported was need for updating knowledge, skills and competencies while reasons hindering physicians from attending CME were lack of knowledge and time constraint.     

Children show limited movement repertoire when learning a novel motor skill

Examining age differences in motor learning using real‐world tasks is often problematic due to task novelty and biomechanical confounds. Here, we investigated how children and adults acquire a novel motor skill in a virtual environment. Participants of three different age groups (9‐year‐olds, 12‐year‐olds, and adults) learned to use their upper body movements to control a cursor on a computer screen. Results showed that 9‐year‐old and 12‐year‐old children showed poorer ability to control the cursor at the end of practice. Critically, when we investigated the movement coordination, we found that the lower task performance of children was associated with limited exploration of their movement repertoire. These results reveal the critical role of motor exploration in understanding developmental differences in motor learning.     

Examining the role of two aspects of eWOM in online repurchase intention: An integrated trust–loyalty perspective

As electronic word‐of‐mouth (eWOM) has become an influential information resource for digital consumers who purchase products, understanding how the 2 ways of eWOM influence consumers' online repurchase intention (ORPI) becomes very pivotal. Despite its importance, there is no study in the literature that examined receiving and participating aspects of eWOM in an integrated perspective. The purpose of this study is to understand how 2 controversial eWOM aspects influence ORPI of consumers. Moreover, this study examines the mediating roles of e‐trust and e‐loyalty in the association between 2 sides of eWOM aspects and ORPI. The results indicated that 2 eWOM receiving factors, eWOM quality and eWOM quantity, have positive influences on e‐trust and ORPI. However, as an eWOM participating factor, the eWOM content has no significant influence on ORPI whereas another participating factor, the eWOM intensity, has the greatest impact on ORPI. Furthermore, the findings illustrate that e‐trust has a complementary mediation effect in the association between 2 receiving eWOM aspects and ORPI; likewise, e‐loyalty has a complementary mediation in the relationship between 2 participating eWOM aspects and ORPI.
