Locus of control is a personality variable that manifests itself through an individual’s perception of the reinforcement he receives. This belief system is based on a continuum ranging from the perception that rewards are completely contingent upon one’s behavior to the belief that only luck, chance, or fate control one’s life. This construct has received considerable attention within the realm of psychology, but is conspicuous by its absence in sport and physical education literature. The purpose of this study was to compare the locus of control of highly skilled Dutch (N = 35) and American (N = 44) women softball players. The Rotter internal-external locus of control scale was utilized to determine internal-external orientations of the subjects. Data were analyzed by using ANOVA and product moment correlations. Statistically significant (.01 level) differences in locus of control were found. American women softball players were significantly more internally oriented than were their Dutch counterparts. © 1977 Taylor 8 Francis Group, LLC.

In attempting to derive the minimal component of the Poggendorff figure which would still produce an illusion, responses to three types of transversal were measured. One was the customary solid line type; a second type presented the two segments sequentially, alternating between them; and the third consisted of a moving dot which traveled the transversal path. Each transversal was shown with and without verticals, for a total of six conditions. Ten subjects in each condition adjusted the luminous transversal until the segments appeared to be collinear. Figures with verticals present showed a greater magnitude of illusion than those without, and discrepancies for moving dot transversals were greater than those for comparable solid line figures. Since alternating transversals were not significantly larger than solid line figures, it was concluded that the magnitude of the moving dot effect could not be attributed to temporal sequence. An eyemovement hypothesis was suggested instead. © 1977 Psychonomic Society, Inc.

The inappropriate constancy scaling notion of geometric illusions was explored by employing a textural analogue of the Ponzo figure. Ten Ss estimated the length of a horizontal line by equating it with varying companion lines in the context of the Ponzo figure, a textural analogue, and a baseline control in which the lines appeared with no surrounding contours. The textural analogue had the added feature of imposing no contours at the ends of the horizontal lines. It was found that length estimates were significantly different between the horizontals of the Ponzo figure and control stimuli, but not between the texture figure and a context-free control. The results suggest that inappropriate constancy scaling plays a minor role at best in the perception of geometric illusions. © 1973 Psychonomic Society, Inc.

Assessed the effects of transgression on self-aggression and depression in 96 high school students. Male confederates induced 1/2 of the Ss to transgress by deceiving the E. As a measure of self-aggression all Ss gave themselves electric shocks of intensity which they personally selected. Ss were also given behavioral and subjective-report measures of depression, including the Mood Adjective Check List. Transgressing Ss showed significantly more self-aggression. Transgressing Ss also showed changes on behavioral measures of depression but not on subjective-report measures. Females showed significantly more self-aggression than males regardless of condition. Findings suggest that the altruistic behavior found to occur after transgression may be engaged in for its self-punitive aspect as well as, or rather than as, a means of social restitution, as has been previously suggested. Contrary to the suggestion of some theories of depression, self-punishment did not appear to alleviate depression.

A field experiment was conducted to investigate the effects of communicator-recipient similarity and verbal communication upon the attitudes and behavior of pregnant women. Similarity was varied on two dimensions, pregnancy and color; and these factors were crossed with three communication conditions: (1) information on the advantages of rooming-in and breast feeding; (2) information combined with personal endorsement; and (3) no-information control. Both a pilot study and the main experiment showed no important differences in the amount of attitude change or behavioral compliance between the communication conditions. There were also no significant differences in attitude change as a function of similarity in pregnancy. However, a significantly higher proportion of mothers breast fed and roomed-in when the communicator was pregnant and similar than when she was nonpregnant and dissimilar. Similarity in color had no effect upon attitudes or behavior for the topic of rooming-in. But when the communicator was dissimilar in color there was significant negative change in attitudes toward breast feeding. Similarity in color also increased breast feeding. Attitudes and actions were related; mothers with initially favorable attitudes were more likely to comply for both issues. But with only one exception, attitude change was unrelated to behavioral compliance. The results are discussed in terms of visible similarity as a source of information or cues for action. © 1972.

Proposed that the cue of relative size may facilitate depth perception in accordance with a crossed or uncrossed disparity in stereograms in which both tendencies are equally represented. A concurrent concept was that the latency associated with the perception of depth in random-dot stereograms may be due, in part, to a cue conflict between binocular disparity and relative size. 4 male and 2 female graduate students were given 8 presentations of 5 stereographic stimuli, in which disparity was ambiguous but relative size was systematically altered. Ss were tested for direction of depth preferences and response latency. Both the relative-size effects and an uncrossed disparity bias were evidenced in the data. The latter effect was attributed to binocular rivalry between dissimilar elements in the stereoscopic half-fields. It is concluded that depth cue relationships are more complex than had been suggested by simple dominance theories.
