Aims: To determine whether or not a Learning Disability(LD) label leads to stigmatization. Study Design: This research used a 2(sex of participant) x 2(LD label)x 2 (Sex of stimulus person) factorial design. Place and Duration of Study: Bucknell University, between October 2010 and April 2011. Methodology: Sample: We included 200 participants (137 women and 63 men, ranging in age from 18 – 75 years, M = 26.41. Participants rated the stimulus individual on 27 personality traits, 8 Life success measures, and the Big-5 personality dimensions. Also, participants completed a Social Desirability measure. Results: A MANOVA revealed a main effect for the Learning Disability description, F(6, 185) = 6.41 p< .0001, eta2 = .17,for the Big-5 personality dimensions, Emotional Stability, F(1, 185) = 13.39, p < .001, eta2 = .066, and Openness to Experiences F(1,185) = 7.12, p< .008, eta2 = .036.Stimulus individuals described as having a learning disability were perceived as being less emotionally stable and more open to experiences than those described as not having a learning disability. Another MANOVA revealed a main effect for having a disability or not, F(8, 183) = 4.29, p< .0001, eta2 = .158, for the Life Success items, Attractiveness, F(1, 198) = 16.63, p< .0001, eta2 = .080, and Future Success,F(1, 198) = 4.57, p< .034, eta2 = .023. Stimulus individuals described as having a learning disability were perceived as being less attractive and with less potential for success than those described as not having a learning disability. Conclusion: The results of this research provide evidence that a bias exists toward those who have learning disabilities. The mere presence of an LD label had the ability to cause a differential perception of those with LDs and those without LDs.

This study focused on the effects of socioeconomic exclusivity indicators on college students¿ attitudes toward a hypothetical private liberal arts university. Students enrolled in two undergraduate courses in Education at an elite private liberal arts university in the northeast were randomly presented with one of three versions of an admissions brochure describing a fictitious university. The three versions of the brochure varied in their portrayals of the institution¿s financial exclusivity, ranging from high exclusivity to low exclusivity. Each student was asked to review the brochure and respond to a questionnaire, containing items pertaining to the overall desirability of the institution, as well as its student culture, academic program, campus traditions, and alumni network. Based on Thorstein Veblen¿s theory of the leisure class and Pierre Bourdieu¿s theory of social reproduction, it was hypothesized that students would judge the institution most favorably in all areas under the high exclusivity condition and least favorably under the low exclusivity condition. It was further hypothesized that differences in students¿ ratings of institutional desirability would be mediated by their own financial aid statuses. Results of a two-way multivariate analysis of variance (MANOVA) revealed significant (p < .05) interactive effects of institutional exclusivity and student aid status on the perceived desirability of the academic program and campus traditions of the institution. While recipients of need-based financial aid tended to rate more socioeconomically exclusive institutions more favorably on these two variables, those who were not receiving need-based financial aid tended to rate such institutions less favorably. Implications of the findings for student affairs practice are discussed and recommendations for further research are presented.
