Applied sport psychology: Are we a profession?

Although the field of applied sport psychology has developed, it faces further challenges on its way towards gaining greater professional status. The following principal criteria of professionalism are proposed as a test of such status (Carr, 1999): (a) provide an important public service; (b) underpinning knowledge base; (c) organizational regulation; (d) distinct ethical dimension; and (e) professional autonomy. This paper undertakes to explore the nature of implications for practice and the extent to which the suggested principal criteria justify a distinctive applied sport psychology profession. In doing so, we hope to stimulate debate on these, and other issues, in order that an even greater professionalization of our applied discipline may emerge

Does priming really put the gloss on performance?

Priming has recently emerged in the literature as offering advantages in the preparation for skilled performance. Accordingly, the current study tested the efficacy of imagery against a priming paradigm as a means of enhancing motor performance: in essence, contrasting a preparation technique primarily under the conscious control of the performer to an unconscious technique promoting automaticity. The imagery intervention was guided by the PETTLEP model, while the priming intervention took the form of a scrambled sentence task. Eighteen skilled field-hockey players performed a dribbling task under imagery, priming, skill-focus, and control conditions. Results revealed a significant improvement in speed and technical accuracy for the imagery condition as opposed to the skill-focus, control, and priming conditions. In addition, there were no significant differences in performance times or technical accuracy between the priming and control conditions. The study provides further support for the efficacy of imagery to elicit enhanced motor skill performance but questions the emerging emphasis on priming as an effective tool in preparation for physical tasks

Entangled maximal mixings in U_PMNS=U_l^dagger U_nu, and a connection to complex mass textures

We discuss two different configurations of U_PMNS=U_l^dagger U_nu with maximal mixings in both U_l and U_nu. The non-maximal mixing angles are assumed to be small, which means that they can be expanded in. Since we are particularly interested in the implications for CP violation, we fully take into account complex phases. We demonstrate that one possibility leads to intrinsically large theta_13 and strong deviations from maximal mixings. The other possibility is generically close to tri-bimaximal mixing, and allows for large CP violation. We demonstrate how the determination of the theta_23 octant and the precision measurement of delta_CP could discriminate among different qualitative sub-cases. In order to constrain the unphysical and observable phases even further, we relate our configurations to complex mass matrix textures. In particular, we focus on phase patterns which could be generated by powers of a single complex quantity eta=theta_C exp(i Phi), which can be motivated by Froggatt-Nielsen-like models. For example, it turns out that in all of the discussed cases, one of the Majorana phases is proportional to Phi to leading order. In the entire study, we encounter three different classes of sum rules, which we systematically classify.Comment: 27 pages, 6 tables, 1 figure. Shortened version to appear in Phys. Rev.
