An fMRI study of imagined self-rotation

In the present study, functional magnetic resonance imaging was used to examine the neural mechanisms involved in the imagined spatial transformation of one’s body. The task required subjects to update the position of one of four external objects from memory after they had performed an imagined self-rotation to a new position. Activation in the rotation condition was compared with that in a control condition in which subjects located the positions of objects without imagining a change in selfposition. The results indicated similar networks of activation to other egocentric transformation tasks involving decisions about body parts. The most significant area of activation was in the left posterior parietal cortex. Other regions of activation common among several of the subjects were secondary visual, premotor, and frontal lobe regions. These results are discussed relative to motor and visual imagery processes as well as to the distinctions between the present task and other imagined egocentric transformation tasks.     

Sex typing: Construct and measurement issues

This study examined the relationships among commonly used measures of sex typing. A sample of 101 children, three to five years of age, were each seen on three occasions and administered six different measures of sex typing. The results showed that relations among the various measures of sex typing were quite modest for girls and only moderate for boys. Gender constancy scores did not mediate the relationships among measures for either girls or boys. The results are interpreted as supporting a multidimensional view of children's sex typing and as urging caution in generalizing results based on single measures of sex typing.     

Factor structure and psychometric characteristics of the beck depression inventory-II

The present study evaluated the factor structure and psychometric properties of the Beck Depression Inventory-II (BDI-II; Beck, Steer, & Brown, 1996) in the nonclinical sample of 230 young adults. The BDI-II is a revised version of the BDI-IA. We evaluated the fit of three alternative models to the sample data, using confirmatory factor analysis. Results provided support for the fit of the oblique three-factor model. The BDI-II and factor scales had satisfactory coefficient alpha indices. We obtained gender differences on the BDI-II item, total, and factor scale scores. We examined the relations of the BDI-II with demographic variables and with other self-report measures of social desirability, anxiety, depression, stress, and self-esteem. We also examined the issue of whether specific self-report measures of anxiety and depression assess separate or different constructs. We discuss the limitations of the present study.     

Letters to santa claus: Elementary school-age children's sex-typed toy preferences in a natural setting

Sex-typed toy preferences were assessed in a nonrestrictive, ecologically valid manner. Letters to Santa Claus requesting Christmas presents, written by 154 elementary school-age children, were analyzed for number and sex-stereotypy of toys requested. Girls requested more toys than boys and children more often requested nonsex-typed (neutral) than sex-typed toys. Girls were especially likely to request neutral toys, while boys were equally likely to request neutral or masculine-typed toys. However, children preferred sex-appropriate to sex-inappropriate toys. The results support efforts to investigate both neutral and sex-typed toy preferences in natural contexts.     

Diversity in Genetic Counseling: Past,Present and Future

Despite decades of efforts to increase ethnic and racial diversity among genetic counselors, African Americans, Hispanics and American Indians, currently constituting almost one-third of Americans, remain only meagerly represented among genetic counselors at a level far under that seen in other health professions. This paper provides the first comprehensive effort to archive published and unpublished initiatives to increase ethnic and racial diversity in the profession. It also provides a review of national data and diversity initiatives in the health workforce in general. The paper reviews diversity initiatives in other health professions and suggests ways to improve recruitment and retention of underrepresented populations into genetic counseling. Increasing the diversity of the genetic counseling workforce stands not only to expand access to genetic services but also to improve the quality of genetic care provided to the American public.     

Minimal conditions for the creation of a unit relationship: the social bond between birthdaymates

We hypothesize that sharing a birthday is sufficient to create a unit relationship. Two studies demonstrated that individuals cooperated more in a prisoners dilemma game when their (fictitious) opponent shared their birthday. They also reacted more negatively to betrayal and were less sensitive to relative gains for self versus other. © 1998 John Wiley & Sons, Ltd.
