Abstract: Background: Professionals in the health sciences strive to enhance health outcomes, however, the design of certain medical and scientific technologies, such as electroencephalography (EEG) systems, illustrates how racial disparities limit the generalizability of the research findings to Black and African American populations. Specifically, the design of EEG systems, often relying on a fitted cap and gel for strong brain signaling, fails to accommodate the various hair types and styles commonly found among Black and African American populations. Therefore, the purpose of this study was to (Aim 1) evaluate feasibility of using the current EEG cap for assessing acceptability, appropriateness, practicality, and implementation in Black student-athletes and (Aim 2) explore the feedback and suggestions from Black student-athletes to discuss current EEG measurements and refine recruitment strategies and data collection protocols for EEG in sport research. Black student-athletes (n = 34) were surveyed to gather demographics and hair style/type information. Additionally, survey questions related to EEG cap feasibility (e.g., acceptability, appropriateness, practicality, and implementation) were asked. Data analysis revealed that overall, Black student-athletes exhibited a tendency towards dissatisfaction with the current EEG cap design being acceptable (M = 2.62, SD= 1.03), particularly regarding issues such as gel application and the overall design's compatibility with various hair types. Perceptions regarding the practicality of implementation varied, with concerns about difficulty in cap placement (M = 2.76, SD = 1.03) and anticipated time spent on hair care post-usage (M = 4.09 hours, SD = 2.08). Additionally, while there was some willingness to participate in studies using the EEG cap design (n = 12, 35%), responses indicated a mixed attitude, with a significant portion expressing reluctance (n = 17, 50%) or neutrality (n = 5, 15%) towards participation. Participants were invited to complete a follow-up focus group to further explore their feedback and suggestions. The focus group results (n = 2) revealed that participants wanted researchers to “think about them,” expressed disheartenment at the continuous treatment, called for a more urgent approach to inclusivity, and requested greater transparency about EEG measurements for potential participants. Furthermore, the participants conveyed a mix of disappointment and resignation towards ongoing marginalization, emphasizing the necessity for transparency and honesty in research practices to demonstrate respect towards participants and address systemic biases effectively. Additionally, it revealed the urgent need for active consideration and inclusion of Black athletes in research processes and technology development, highlighting the importance of diversity and equitable access to foster inclusivity and scientific advancement. Participants In conclusion, this study highlights the critical need to address and dismantle the racial biases present in current EEG cap designs and methodologies.
