Description
The interaction between visual fixations during planning and performance in a
dexterous task was analyzed. An eye-tracking device was affixed to subjects during
sequences of null (salient center of mass) and weighted (non salient center of mass) trials
with unconstrained precision grasp. Subjects experienced both expected and unexpected
perturbations, with the task of minimizing object roll. Unexpected perturbations were
controlled by switching weights between trials, expected perturbations were controlled by
asking subjects to rotate the object themselves. In all cases subjects were able to
minimize the roll of the object within three trials. Eye fixations were correlated with
object weight for the initial context and for known shifts in center of mass. In subsequent
trials with unexpected weight shifts, subjects appeared to scan areas of interest from both
contexts even after learning present orientation.

Description
The primary purpose of this research was to evaluate the differences in retention intention between men and women in collegiate aviation programs. Data was collected through the use of surveys and follow-up interviews. It was found that women are no more likely than men to consider dropping out of their academic institution or abandoning the pursuit of a career in aviation. Regardless of retention intention, women in collegiate aviation programs report a much lower sense of belonging than men, which can be attributed to low self-efficacy, a lack of representation of women, and feeling disconnected from both peers and faculty. All of the women interviewed did not identify gender as a salient identity when describing these similar experiences and instead pointed to other social identities and factors to explain their feelings. Survey and interview results, however, indicate that women in collegiate aviation programs often responded to questions similarly regardless of experience level, race and ethnicity, or sexual orientation.
