Movement imagery ability: development and assessment of a revised version of the vividness of movement imagery questionnaire.

Abstract: The purpose of this research was to amend the Vividness of Movement Imagery Questionnaire (VMIQ; Isaac, Marks, & Russell, 1986) in line with contemporary imagery modality and perspective conceptualizations, and to test the validity of the amended questionnaire (i.e., the VMIQ-2). Study 1 had 351 athletes complete the 3-factor (internal visual imagery, external visual imagery, and kinesthetic imagery) 24-item VMIQ-2. Following single-factor confirmatory factor analyses and item deletion, a 12-item version was subject to correlated traits / correlated uniqueness (CTCU) analysis. An acceptable fit was revealed. Study 2 used a different sample of 355 athletes. The CTCU analysis confirmed the factorial validity of the 12-item VMIQ-2. In Study 3, the concurrent and construct validity of the VMIQ-2 was supported. Taken together, the results of the 3 studies provide preliminary support for the revised VMIQ-2 as a psychometrically valid questionnaire.

Efficacy of external and internal visual imagery perspectives for the enhancement of performance on tasks in which form is important.

Abstract: Three experiments examined the relative efficacy of different imagery perspectives on the performance of tasks in which form was important. In Experiment 1,25 experienced karateists learned a new kata using either external or internal visual imagery or stretching. Results indicated that external visual imagery was significantly more effective than internal visual imagery, which was significantly more effective than stretching. In Experiment 2, 40 sport science students learned a simple gymnastics floor routine under one of four conditions: external or internal visual imagery with or without kinesthetic imagery. Results revealed a significant main effect for visual imagery perspective (external visual imagery was best) but no effect for kinesthetic imagery. Experiment 3 employed the same paradigm as Experiment 2 but with high-ability rock climbers performing difficult boulder problems. Results showed significant main effects for both visual imagery perspective (external visual imagery was best) and kinesth...

Measurement of Transformational Leadership and its Relationship with Team Cohesion and Performance Level

Abstract: The present study explored the construct validity of a Differentiated Transformational Leadership Inventory and its relationship with team cohesion and performance level. Three hundred and nine club standard ultimate Frisbee players in the United Kingdom (mean age = 24.30 years, SD = 3.90) completed an adapted version of Hardy, Arthur, Jones, Shariff, Munnoch, Isaacs, and Allsopp et al.'s (in press) Differentiated Transformational Leadership Inventory and the Group Environment Questionnaire (Carron, Widmeyer, & Brawley, 1985). Confirmatory factor analysis revealed evidence for the factorial and discriminant validity of the leadership inventory. Furthermore, results demonstrated that the leadership behaviors of fostering acceptance of group goals and promoting team work, high performance expectations, and individual consideration significantly predicted task cohesion; and fostering acceptance of group goals and promoting teamwork significantly predicted social cohesion. Performance level moderated these re...

The Effects of a Motivational General-Mastery Imagery Intervention on the Sport Confidence of High-Level Badminton Players

Abstract: A multiple-baseline across-participants design was used to examine the effects of a Motivational General-Mastery imagery intervention on the sport confidence of 4 high-level junior badminton players. Sport confidence data were collected once a week for 21 weeks prior to international and county matches. The imagery intervention consisted of six imagery sessions (two per week for 3 weeks) and was administered using a multiple-baseline design with interventions commencing at Weeks 5, 7, 9, and 11 for Participants 1, 2, 3, and 4, respectively. Results of visual inspection and Binomial tests suggested significant increases in sport confidence for Participants 1 and 2, a significant decrease in sport confidence for Participant 3, and a delayed increase in sport confidence for Participant 4. The results are discussed in terms of the implications of using mastery imagery and the usefulness of multiple-baseline designs for furthering imagery research.

Personal Knowledge: Towards a Post-Critical Philosophy

Abstract: The Study of Man. By Michael Polanyi. Price, $1.75. Pp. 102. University of Chicago Press, 5750 Ellis Ave., Chicago 37, 1959. One subtitle to Polanyi's challenging and fascinating book might be The Evolution and Natural History of Error , for Polanyi is at pains to expunge what he believes to be the false notion contained in the contemporary view of science which treats it as an object and basically impersonal discipline. According to Polanyi not only is this a radical and important error, but it is harmful to the objectives of science itself. Another subtitle could be Farewell to Detachment , for in place of cold objectivity he develops the idea that science is necessarily intensely personal. It is a human endeavor and human point of view which cannot be divorced from nor uprooted out of the human matrix from which it arises and in which it works. For a good while
