The recent proliferation of electronic video games has caused an outcry from those who question the merits of the games, while others maintain the games improve eye-hand coordination. At present, no empirical data are available to indicate whether there are differences in eye-hand coordination between video game users and non-users. Comparing 31 video game users and 31 non-users showed users have significantly better eye-hand motor coordination on a pursuit rotor. However, no relationship was found between an individual's eye-hand motor coordination and the amount of time spent weekly playing video games or the length of experience with video games.

These areas have varying degrees of utility in selection and receive different emphasis in Navy and Air Force selection pzccedures. The Early Years The Army Air Forces Aviation Psychology Program conducted a comprehensive investigatiou of the use of personality measures to predict aviation performance (10). The thrust of the effort was to determine the predictive value of a number of commercially available tests. A secondary consideration was to use questionnaire items from these tests to establish a pool of items of high predictive value in aviation screening. Although performance measures in an actual combat environment were desirable criteria, they were not obtainable. The criterion used for the validation efforts was graduation/ elimination from primary flight training. These studies are summarized in Table 1.

The present study presents information regarding the development and validation of a new personality instrument which is intended to measure the degree of obsessive-compulsive traits. Data indicate that the instrument shows both promising reliability and concurrent validity. Developed primarily for research purposes, the scale may have therapeutic assessment applicability in a clinical setting.
