The effects of sex on the performance of 4 spatial mazes (Morris water task, landmark task, radial arm maze, and egocentric radial arm maze) were studied in male and female rats given medial frontal lesions. Operated rats from both sexes were impaired at all of the tasks, but the frontal males were much less impaired than frontal females on the Morris task and the radial arm maze, both of which require animals to use multiple visual-spatial cues for their successful solution. Males also performed better on the egocentric maze. In contrast, frontal females performed better than frontal males at the landmark task, which is best solved by using a single spatial cue. The only sex difference in unoperated rats was a small advantage for females on the egocentric task. The sex differences may reflect an underlying difference in cortical organization or a differential response to cortical lesion in males and females.

This study examined the relationship between body image and sexual avoidance. Of particular interest was whether this relationship was mediated by other variables. Participants were 362 undergraduate students who responded to a battery of questionnaires pertaining to three aspects of body image, sexually avoidant behavior, and three mediator variables, which included sexual esteem, sexual satisfaction, and sexual desire. Consistent with previous studies, a relationship between body image and sexual avoidance was found, indicating that those with a more negative body image displayed a greater tendency to avoid sexual activity. Furthermore, sexual esteem, sexual satisfaction, and sexual desire appeared to mediate this relationship. Implications of these results suggest that these mediator variables are important in the relationship between body image and sexual avoidance, and may be useful targets for those seeking treatment for sexual avoidance issues. Limitations of the study and avenues for future research are discussed.
