AB  - Neuropsychological research has been limited in the representation of cultural 
      diversity due to various issues, raising questions regarding the applicability of 
      findings to diverse populations. Nonetheless, culture-dependent differences in 
      fundamental psychological processes have been demonstrated. One of the most basic 
      of these, self-construal (individualism, collectivism), is central to how many 
      other differences are interpreted. Self-construals may have possible consequences 
      on social interactions, emotions, motivation, and cognition. This study aimed to 
      evaluate the impact of self-construal on neurocognitive functions in older 
      adults. A total of 86 community-dwelling older adults 60 years and older were 
      assessed with three common self-report measures of self-construal along 
      individualism and collectivism (IC). A cognitive battery was administered to 
      assess verbal and non-verbal fluency abilities. Latent profile analysis (LPA) was 
      used to categorize individuals according to IC, and one-way analyses of 
      covariance (ANCOVA), including relevant covariates (e.g., ethnicity, gender, 
      linguistic abilities), were used to compare neurocognitive functions between 
      individualists and collectivists. Collectivists outperformed individualists on 
      left frontally-mediated measures of verbal fluency (action, phonemic) after 
      controlling for relevant covariates, F ((1,77)) = 6.942, p = 0.010, eta (2) = 
      0.061. Groups did not differ on semantic fluency, non-verbal fluency, or 
      attention/working memory (all ps > 0.05). These findings suggest a cognitive 
      advantage in collectivists for verbal processing speed with an additional 
      contribution of left frontal processes involved in lexicosemantic retrieval. 
      Self-construal may provide a meaningful descriptor for diverse samples in 
      neuropsychological research and may help explain other cross-cultural 
      differences.
