SUMMARY OR ABSTRACT
Text of Note
There has been a long history of investigation into the role of language in human development and its influence on cognition. By means of studying the effect of bilingualism on the human brain, researchers have been able to acquire insight into the differences between cortical organization of primary and secondary languages, as well as to learn about cognitive and neural modalities of bilingual language processing, and its relationship with memory and cognition. As the population of the United States becomes increasingly multicultural and multilingual, cross-cultural considerations should be included in the development of the neuropsychological tests to account for underlying differences in information-processing styles. However, current neuropsychological measurements do not adequately incorporate cultural and linguistic factors into the assessment process. Although numerous studies have investigated the influence of culture and language on neuropsychological functioning, few have included the Slavic language speakers in their samples. The present study utilized a correlational design to explore the difference between normative performance on the Rey-Osterrieth Complex Figure Test (ROCF) in primary English speakers and primary Russian speakers currently living in Northern California. The objective of this study was to determine whether linguistic and cultural differences are related to performance on non-verbal neuropsychological tests in cognitively intact subjects. The number of participants for this pilot study was chosen based on a previous research study on a similar topic. A total of 46 individuals, 23 primary English speaking and 23 primary Russian speaking participants were administered a nonverbal neuropsychological test. Demographic questionnaire, GAD 7-Item Scale, and PHQ-9 were mainly used as distraction items, but also to screen for potential acute depressed or anxious state. Results revealed no significant statistical differences or pattern differences in test performance between two groups. However, primary English-speaking group performed slightly better on the Copy Presence and Accuracy (CPA) and Delayed Retention (DR) domains of the BQSS, and primary Russian-speaking group performed better on the Organization (ORG). Further statistical analysis showed that education positively correlated with all of the six categories of Rey-O scores. These results call for a more thorough examination of the design, trends, and patterns relevant to culture-specific experiences.
