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.     

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.     

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).     

The effects of load variability in short-term memory task

Six groups of Ss viewed briefly exposed arrays of letters, half designated high-valued and half low-valued. Immediately after each exposure Ss wrote down as many of the stimuli as they could remember. For three groups, the number of letters in each exposure was constant from trial to trial; for the remaining three groups, the number of letters in each exposure varied from trial to trial. This tested the hypothesis that load variability influences the development of an efficient response strategy which, in turn, affects the processing of information stored in short-term memory. The data supported this hypothesis. Performance was superior under the constant load condition due to the ability of these Ss to correctly report both high- and low-valued letters. Poor performance was observed under the variable load condition because of a decrease in the number of low valued letters correctly reported.     

Motivated to penalize: women's strategic rejection of successful women

Two studies tested the hypothesis that females penalize women who succeed in male gender-typed jobs to salvage their own self-views regarding competence. The authors proposed that women are motivated to penalize successful women (i.e., characterize them as unlikable and interpersonally hostile) to minimize the self-evaluative consequences of social comparison with a highly successful female target. Results supported the hypothesis. Whereas both male and female participants penalized successful women, blocking this penalization reduced female--but not male--participants' self-ratings of competence (Study 1). Moreover, positive feedback provided to female participants about their potential to succeed (Study 2) weakened negative reactions to successful women without costs to subsequent self-ratings of competence. These results suggest that the interpersonal derogation of successful women by other women functions as a self-protective strategy against threatening upward social comparisons.
