In the U.S, Middle Eastern (M.E) students often struggle with negative biases toward them and experience isolation, discrimination, and report a lack of meaningful interactions with U.S. students. Against this backdrop, this dissertation explored the impact of enacted similarity and nonverbal immediacy on social attraction and friendship-potential between same-sex U.S. and M.E. international students during first time interactions on Zoom. A 2 (M.E. vs. U.S. confederate) x 2 (low vs. high similarity) x 2 (low vs. high nonverbal immediacy) x 2 (pre- vs. post-interaction) experimental design was employed, with participants reporting on their perceptions after viewing a profile of a confederate and then again after they interacted with the confederate on Zoom for three minutes. Pre-interaction results indicated that M.E. women were perceived as the most socially attractive, highest friendship potential, and as most likely to engage in pleasant interaction, compared to the other three groups. This finding emerged even though U.S. women rated fellow U.S. women as more similar to them than they rated M.E. women. A potential explanation is intersectionality of gender and ethnicity, with U.S. women stereotyping M.E. women as quiet, submissive, and oppressed, and therefore have sympathy for them and expect them to be kind. Post-interaction results revealed that in interactions between U.S. students, similarity impacted friendship potential but not social attraction, while nonverbal immediacy had a significant impact on both. In intercultural interactions between the U.S. and M.E. students, both nonverbal immediacy and similarity impacted social attraction and friendship potential. There were especially sharp drops in social attraction and friendship potential when the confederates enacted low levels of nonverbal immediacy. Overall, nonverbal immediacy had stronger and more consistent effects compared to similarity. Results indicate that to make positive impressions, both U.S. and M.E. students should use nonverbal immediacy cues such as smiling, leaning in, and being attentive to their interactional partner rather than looking away. Future directions include determining if findings can be generalized to face-to-face interactions and to perceptions of individuals from various cultures.
