Objective Confrontation naming tests are used to examine an individual’s lexical retrieval. We examined the relationship of perceived workload and acculturation in three ethnic groups’ Cordoba Naming Test (CNT) performance. Methods The sample consisted of 32 Latinx, 11 Caucasians, and 10 Asian; all neurologically and psychologically healthy residents. All participants completed the CNT and subscales of the Abbreviated Multidimensional Acculturation Scale (AMAS) in English. AMAS was used to measure acculturation and the NASA-Task Load Index (NASA TLX) measured perceived workload. Results The CNT showed that the Caucasian group outperformed the Latinx group, p = 0.024, ηp2 = 0.14. However, the Latinx group reported better CNT performance compared to the Caucasian group, p = 0.023, ηp2 = 0.14. No differences were found between groups on the AMAS. Finally, we found a significant relationship between CNT and NASA-TLX subscales (i.e., performance, mental demand, effort, frustration, & overall perceived workload) in the Latinx group, r = −0.562 to −0.398, p Discussion Results showed the Latinx group demonstrated worse CNT performance compared to the Caucasian group. To our knowledge, this is the first study to evaluate confrontation naming performance in an ethnically diverse sample. Furthermore, we found the Latinx group reported a higher perceived performance on the CNT compared to Caucasians. Our results indicated a relationship between CNT performance and perceived workload in our Latinx sample as opposed to the Caucasian and Asian groups. Future research is needed with a larger sample size; moreover, additional research should investigate interactions between perceived workload, acculturation, and other cultural variables (e.g., bilingualism) in the interpretation of test performance in diverse ethnic groups. |
