Accuracy of estimations of body-frame size as a function of sex and actual frame size

Body-frame size is an important factor in determining an optimal body weight for a given height. Previous studies have indicated that many individuals incorrectly estimate their body-frame size, and, as a result, incorrectly assess their ideal weight. The present study investigated the accuracy of estimation of body-frame size as a function of sex and actual frame size. The subjects were 66 men and 52 women participating in a community adult fitness program. Data indicated that medium-framed individuals were the most accurate in their estimations of body-frame size. Also, women were twice as likely to be accurate as were men. These results are interpreted to mean that most people assume they are medium-framed and that there is a sex difference in the way body-frame size is estimated.     

Effects of preshot routine on free-throw shooting

The effect of prohibiting the use of a preshot routine on free-throw shooting in competitive situations was investigated. 25 male high school basketball players were instructed to attempt 50 free throws alternating in blocks of 10 between the use of their preshot routine and shooting without it. To make the situation competitive, subjects were run in groups of five and their performance was recorded on a large easel placed to the side of the free-throw line. A significantly larger number of baskets were made in the preshot routine condition than without the routine. A competitive situation led to a greater decrement in baskets than had been reported in 1986 by Lobmeyer and Wassermen during noncompetitive free-throw shooting.     

Re-examining the home disadvantage in professional ice hockey

Occurrence of the home disadvantage in professional ice hockey was examined by analyzing shootout data from 2005 through 2008. Results indicated that teams involved in shootouts playing at their home arenas did not lose significantly more games at home than on the road. Results did not support the hypotheses that emphasize the roles of physical contact and diffusion of responsibility in accounting for past failures to find the home disadvantage in professional ice hockey.     

Validities of the Physical Estimation Scale in predicting running times

Two studies were conducted with the purpose of examining the validity of the 12-item Physical Estimation Scale, developed by Safrit and Wood (1985), as a predictor of running performance. Physical Estimation Scale scores were not significantly related to running time at the 5-mi. distance but were significantly correlated with predicted and actual marathon finishing times.     

An investigation of the Mini-Mult validity scales

Examined the ability of the Mini-Mult validity scales to detect invalid MMPI profiles. When 34 invalid MMPI profiles were rescored with the Mini-Muir only 17 of the 34 profiles invalidated by the full MMPI were detected with the Mini-Mult. This included 14 of 27 profiles invalidated by an elevated F scale; 2 of 4 profiles invalidated by an elevated L scale and 1 of 3 profiles invalidated by an elevated K scale. Only 14 of 27 profiles invalidated by an F-K ratio of K11 were detected. When new conversion values for the Mini-Mult were utilized, the detection rate improved considerably for the F scale and the F-K ratio.     

Attitudes toward the metric system 15 years later

This follow-up study investigated whether attitudes toward the metric system have changed over the last 15 years. 132 subjects ranging in age from 18 to 45 years participated by filling out a 7-item survey designed to measure attitudes toward the metric system. Each survey item was scored using a 5-point rating, e.g., "the change to the metric system will create more problems than it solves," 1: strongly agree and 5: strongly disagree. Scores were compared to those obtained for a similar sample in 1983. Comparisons using t tests indicated no significant differences between attitude scores from 1983 to 1998 for either men (t64 = .95) or women (t133 = .06).     

Utility of the Mini-Mult in a Child Guidance Clinic Setting

The utility of the Mini-Mult was examined with emotionally disturbed adolescents and parents of emotionally disturbed children. Close statistical correspondence was noted between the Mini-Mult and the full MMPI. A decrease in correspondence was noted when similarity of profile elevation was examined.     

a comparison of the Bem Sex Role Inventory and the PRF ANDRO Scale

The Bem Sex Role Inventory and the PRF ANDRO Scales were administered to 158 (59 males, 99 females) undergraduates enrolled in an introductory psychology course. Data analysis was carried out by examining the amount of agreement between the BSRI and the PRF ANDRO Scale in terms of assignment of sex-role outcome. When both sexes are combined, only 66 of 158 (42%) subjects fell in the same sex-role category.
