Research indicates that demographic (e.g., age, education) and sociocultural (e.g., acculturation) factors can impact neuropsychological test performance among ethnoculturally diverse adults. Some studies suggest that greater acculturation to the United States (U.S.) is associated with better neurocognitive functioning, though no meta-analysis to date has examined this relationship. This review provides a comprehensive synthesis of the literature and determines the magnitude of the relationship between acculturation and neuropsychological test performance.

A literature search explored all published articles through January 1, 2024, using three databases (i.e., PubMED/MEDLINE, PsycInfo, PsycNET). Data to calculate study effect sizes (i.e., Fisher’s z) were extracted from in-text results, tables, and figures.

Findings (k = 18 included in quantitative analyses) revealed a small to medium (r = 0.29, partial r = 0.20, p < .01), statistically significant relationship between higher U.S. acculturation and better neuropsychological test performance. Moderation analyses indicated that language of testing emerged as a significant moderator, testing in English yielded larger effect sizes compared to testing in other languages (B = 0.29, p < .05).

Neuropsychological test performance is significantly associated with U.S. acculturation, and results suggest that the magnitude may vary depending on study methodologies and samples (e.g., ethnocultural group, U.S. born vs. immigrant) examined. The current review also provides recommendations for incorporating acculturation assessment into clinical practice and highlights the need to examine the clinical utility of acculturation tools in conjunction with neuropsychological tests to assist in clinical decision-making with ethnoculturally diverse populations.

To describe the drivers of dietary behaviours among young South Asian adults (18-35 years) in Australia and examine the influence of acculturation and the host environment in shaping these behaviours.

A cross-sectional qualitative study design was used to collect data through Zoom focus groups. The analysis of the qualitative data followed Vears and Gilliam’s Inductive Content Analysis approach. Demographic data were presented descriptively, and the findings were reported in accordance with the Standard for Reporting Qualitative Research.

Sydney, New South Wales, Australia.

A total of 21 young South Asian migrants (aged 18-35 years), mostly from India and Pakistan, participated in four online focus groups.

Six main themes were identified, highlighting the complex interplay of acculturation, cultural identity, family influence, and other socio-economic factors in shaping dietary behaviours. 1. Acculturation and exposure to diverse Cuisines, 2. Interplay between religion and culture during special occasions, 3. Influence of social networks and community norms, 4. Structural and practical constraints shaping food choices, 5. Shifting perceptions around healthy eating, and 6. Empowerment through knowledge. Participants reported incorporating Western and multicultural cuisines, often balancing convenience and cultural preferences.

Numerous drivers, including but not limited to acculturation and the host environment, influence the dietary behaviours of young South Asian adults in Australia. Despite limitations in representativeness, the study provides valuable insights highlighting the need for inclusive health promotion efforts for Australia’s growing South Asian population.

To explore the meanings that newly arrived refugee adolescents residing in the Southeastern USA attribute to foods.

We used methods from cognitive anthropology to assess whether adolescents from different countries share a cultural model of eating behaviours.

A school-based study in a community in the Southeastern USA.

Adolescents (10–17 years) who arrived in the USA on a refugee visa in the previous year.

Adolescents showed consensus in grouping items and in identifying some foods as associated with adults and others with children. There was evidence of a shared model of eating practices across age, gender and number of siblings. Adolescents who had lived in a refugee camp were significantly different in how they grouped items.

Adolescents from nine countries shared a model of eating behaviours; these patterns are consistent with rapid dietary acculturation within 1 year of arrival or with shared models held from pre-arrival. Our finding that adolescents who recently arrived in the USA generally agree about how foods relate to one another holds promise for generalised nutrition and dietary interventions across diverse adolescent groups.

To quantify and compare concurrent within-person trends in lifestyle risks, nutrition status and drivers of food choice among urban migrants in Central Asia.

We collected panel data on household structure, drivers of food choice, nutrition knowledge and diverse measures of nutrition status and lifestyle risk from urban migrants at 0, 3, 6 and 9 months using harmonised methodology in two cities. Trends were analysed using mixed-effects models and qualitatively compared within and between cities.

Ulaanbaatar, Mongolia, and Almaty, Kazakhstan.

200 adults (22–55 years) who migrated to these cities within the past 2 years.

Adjusting for age and sex, each month since migration was positively associated with fasting TAG in Almaty (0·55 mg/dl; 95 % CI: 0·13, 0·94) and BMI (0·04 kg/m2; 95 % CI: 0·01, 0·07), body fat (0·14 %; 95 % CI: 0·01, 0·26) and fasting glucose (0·04 mmol/l; 95 % CI: 0·02, 0·05) and lipids in Ulaanbaatar (P < 0·05). In Almaty, nutrition knowledge (measured using an objective 20-point scale) declined despite improvements in diet quality (measured by Prime Diet Quality Score). The influence of food availability, price and taste on food choice increased in Almaty (P < 0·05). Upon multivariable adjustment, nutrition knowledge was positively associated with diet quality in Almaty and adherence to ‘acculturated’ diet patterns in both cities (P < 0·05). Different trends in smoking, sleep quality and generalised anxiety were observed between cities.

Findings indicate heterogeneous shifts in nutrition, lifestyles and drivers of food choice among urban migrants in Central Asia and provide an evidence base for focused research and advocacy to promote healthy diets and enable nutrition-sensitive food environments.

Stephenson (2000) suggested that acculturation is a phenomenon that immigrants and refugees ubiquitously experience. The level of acculturation is impacted by a person’s choice to allow how much of their cultural traits they decide to keep while adapting to the dominant society cultural traits. Depending on what immigrants find to be important or unimportant, it can influence future generations (i.e., their children) in how they will be developed and adapt into a dominant society. Hispanic-Americans are individuals that were born and reside in the United States and have a family background that extends to one of the Spanish speaking countries in Latin America or Spain. The typical language spoken by Hispanic families other than English is Spanish. It has been reported that Hispanics that are capable of speaking English may be afforded better and greater opportunities to resources. Research shows that a person level of acculturation can influence their cognition. In fact, in one study using a Mexican-American sample that was divided into two groups: high and low. Researchers found that highly acculturated Mexican-Americans outperformed lower acculturated Mexican-Americans on the Wisconsin Card Sorting Test. We evaluated the influence of acculturation in Hispanic-Americans neuropsychological test performance. It was predicted that highly acculturated Hispanic-Americans to American culture would demonstrate better cognitive abilities compared to lower acculturated Hispanic-Americans.

The present study sample consisted of 75 neurologically and psychologically healthy Hispanic-American undergraduate students with a mean age of 19.44 (SD = 1.37). Participants were divided into two acculturation groups: high (n = 39) and low (n = 36). In addition, all the participants completed a comprehensive neuropsychological battery and background questionnaire in English. The Acculturation Rating Scale for Hispanic/Latino Americans is a 20-item scale that was utilized to create our acculturation groups. ANOVAs were used to evaluate cognitive differences between our acculturation groups.

Results revealed that the highly acculturated group outperformed the lower acculturated group on the Weschler Adult Intelligence Scale-Third Edition vocabulary task and the Boston Naming Test, p’s<.05, n.p’s2=.06. Furthermore, results revealed that the lower acculturated group outperformed the highly acculturated group on the Trail Making Test part A and B, and Comalli Stroop part A, p’s<.05, np’s2=.06-.07.

As expected, the highly acculturated group demonstrated better language abilities compared to the lower acculturated group. However, in the opposite direction, the lower acculturated group outperformed the highly acculturated group on several speed attention tasks and one executive functioning task. A possible explanation why the highly acculturated participants demonstrated better language abilities may be attributed that their dominant language is English or they only spoke English. Meanwhile, the opposite could be said for lower acculturated participants that English was not their dominant language or they were bilingual speakers, for that reason they demonstrated better processing speed and executive functioning abilities. Research shows that monolinguals demonstrate better language abilities compared to bilinguals, but the opposite is found on processing speed and executive functioning tasks. Future research should investigate the relationship between bilingualism and acculturation in neuropsychological testing performance of Hispanic-Americans.

The Cordoba Naming Test (CNT) is a 30-item lexical retrieval task that was developed to be administered in multiple languages. Research shows that self-identifying Mexicans residing in Mexico outperform self-identifying Mexicans that reside in the United States on the CNT. Studies indicate that the process of acculturation can influence cognitive performance. Previous studies demonstrated that Generation Z individuals (i.e., people born between 1997 and 2012) have underperformed on the CNT compared to Generation Y individuals (i.e., people born between 1981 and 1996). To our knowledge, no study has examined the influence of acculturation on Generation Z Mexicans’ CNT performance. We expected Mexicans residing in Mexico (MRM) to outperform Mexicans residing in the United States on the CNT and to report higher acculturation traits. We also predicted that acculturation would correlate with CNT performance.

The present study sample consisted of 285 Generation Z psychologically and neurologically healthy Mexicans with a mean age of 20.32 (SD = 1.60). Participants were divided into three groups: MRM, Mexicans residing in the United States, and Mexican-Americans residing in the United States (MARUS). All participants completed the CNT and acculturation measure in Spanish. Acculturation traits were measured by the Abbreviated Multidimensional Acculturation Scale (AMAS). ANCOVAs were used to evaluate differences in the CNT and AMAS (i.e., Spanish language, Latino competency, Latino identity). Pearson’s correlation coefficient was used to evaluate the relationship between acculturation on CNT performance.

MRM outperformed the Mexicans residing in the United States and MARUS on the CNT, p = .000, np2 = .49. The MRM group reported better Spanish language abilities compared to Mexicans residing in the United States and the MARUS groups, p = .000, np2 = .10. Additionally, MRM reported better Latino competency than the MARUS group, p = .000, np2 = .08. Pearson’s correlation coefficient revealed that the MARUS’s Spanish language abilities impacted CNT performance, p = .000, r = .48. In addition, we found that Latino competency correlated with CNT performance, p’s < .05, r’s = .20-.47, in both the MRM and Mexicans residing in the United States groups. Latino identity did not significantly correlate with CNT performance in any group.

Results confirmed that MRM individuals perform better on the CNT than Mexicans residing in the United States and MARUS. Additionally, we found that several acculturation traits correlated with Mexican groups’ CNT performance. Our research indicates that while all Generation Z individuals of Mexican heritage feel strongly connected to their Latino identity regardless of where they live, MARUS feel less competent in Spanish and Latinx culture than MRM and Mexicans residing in the United States. Future work should further explore these differences for better insight into how acculturative factors influence lexical retrieval performance. Future work with bigger sample sizes can additionally examine CNT performance and acculturation in Generation Z first-generation and non-first-generation Mexicans (e.g., second-generation, third-generation) residing in the United States.

A commonly used confrontation naming task used in the United States is The Boston Naming Test (BNT). Performance differences has been found in Caucasian and ethnic minorities on the BNT. The Cordoba Naming Test (CNT) is a 30-item confrontation naming task developed in Argentina. Past research has shown acculturation levels can influence cognitive performance. Furthermore, one study evaluated geriatric gender differences on CNT performance in Spanish. Researchers reported that older male participants outperformed female participants on the CNT. To our knowledge, researchers have not evaluated ethnic differences on the CNT using a geriatric sample. The purpose of the present study was to examined CNT performance and acculturation in a Latinx and Caucasian geriatric sample. It was predicted the Caucasian group would outperform the Latinx group on the CNT. Moreover, the Caucasian group would report higher acculturation levels on the Abbreviated Multidimensional Acculturation Scale (AMAS) compared to the Latinx group.

The sample consisted of 9 Latinx and 11 Caucasian participants with a mean age of 66.80 (SD =6.10), with an average of 14.30 (SD = 2.00) years of education. All participants were neurologically and psychologically healthy and completed the CNT and the AMAS in English. Acculturation was measured via the AMAS English subscales (i.e., English Language, United States. Identity, United States, Competency). A series of ANCOVAs, controlling for years of education completed and gender, was used to evaluate CNT performance and acculturation.

The ethnic groups were not well demographically matched (i.e., years of education and gender).We found that the Caucasian group outperformed the Latinx group on CNT performance p = .012, ηp 2 = .34. Furthermore, the Caucasian group reported higher acculturation levels (i.e., English Language, United States, Identity, United States, Competency) compared to the Latinx group p’s < .05, ηps2 = .42-.64.

To our knowledge, this is the first study to evaluate CNT performance between ethnic groups with a geriatric sample. As expected the Caucasian group outperformed the Latinx group on the CNT. Also, as expected the Caucasian group reported higher English acculturation levels compared to the Latinx group. Our findings are consistent with past studies showing ethnic differences on confrontational naming performance (i.e., The Boston Naming Test), favoring Caucasians. A possible explanation for group differences could have been linguistic factors (e.g., speaking multiple languages) in our Latinx group. Therefore, since our Latinx group reported lower levels of English Language, United States identity, and United States competency the Latinx group assimilation towards United States culture might of influence their CNT performance. Future studies with different ethnic groups (e.g., African-Americans) and a larger sample size should examine if ethnic differences continue to cross-validate in a geriatric sample.

There is equivocal evidence that acculturation is associated with cognition. Various factors may contribute to ambiguous findings in the neuropsychology setting, including psychometric limitations of tools available for assessing acculturation as well as the frequent conflation of bilingualism with acculturation. Additionally, neuropsychological research on acculturation and cognition has largely failed to account for bidimensional models of acculturation, which have greater empirical support over unidimensional models. In response to these limitations and the theoretical literature on acculturation, we developed the Perceived Identity & Ethnicity Scales (PIES), a brief rating scale system to quickly (<2 minutes) capture an individual's perceived acculturative identity across several domains. In the current study, we sought to (1) provide initial psychometric support of the PIES and (2) examine how it relates to cognition in a culturally and linguistically diverse sample.

We recruited 242 individuals from both university and community samples (age=23.7±7.6, range 18-72; <12 Years of Education=4%; 78% Female; 58% Hispanic/Latin American; 69% middle SES; 22% educated outside the USA). In addition to demographic questionnaires, participants completed the PIES; an established measure of acculturation (the Bicultural Involvement Questionnaire, BIQ) and bilingualism (Bilingual Language Profile, BLP); measures of mood (the Depression, Anxiety, Stress Scales, DASS; Apathy Evaluation Scale, AES); and of self-reported cognitive functioning (Everyday Cognition, ECog). A subsample of Spanish speakers (n=86) also completed a cognitive battery validated for use in this population (the Spanish English Neuropsychological Assessment Scales, SENAS). For the first aim, we examined the reliability, validity, and dimensionality of the PIES in the full sample. In the Spanish-speaking subsample, we examined the relationship between the tool and both subjective and objective cognition using linear regression controlling for age, education, sex/gender, and premorbid intellectual functioning.

Measures of internal consistency and dimensionality supported a bidimensional model of acculturation; identification with culture of family origin (PIES-O) was not related to identification with US American culture (PIES-U; r=0.036, p>0.05). Cultural preference scores from the BIQ were associated with PIES-O (r=-0.322) and PIES-U (r=0.277; both ps<0.001) in the expected directions. PIES-O (r=0.350) and PIES-U (r=-0.432) were associated with the ability to speak a language other than English on the BLP (both ps<0.001). PIES-U, but not PIES-O, was also strongly associated with other BIQ and BLP scores as well as with receiving education outside of the USA at medium to large effect sizes (rs=0.3 to 0.6; all ps<0.001). In the subsample, PIES-O and PIES-U were not associated with subjective cognition as measured by the ECog (AR2=0.016, p>0.05); global cognition as measured by the Montreal Cognitive Assessment (MoCA; AR2=0.046, p>0.05); or SENAS cognitive composite scores (AR2=0.016, p>0.05) after controlling for covariates.

Findings provide strong initial psychometric support for the utility of the PIES in the assessment of acculturation. Moreover, these results further support the bidimensional model of acculturation. Acculturation as measured by the PIES was not associated with cognitive abilities in this highly educated and mainly female cross-sectional sample. Longitudinal research accounting for acculturation is needed to elucidate these relationships.
