Belief Reasoning and Emotion Understanding in Balanced Bilingual and Language-Dominant Mexican American Young Children

Clinical Neuropsychology of Bilingual Mexican American Adults: Effect of Language Proficiency and Dominance

OBJECTIVE

To assess the association between language proficiency and absolute dominance on language versus visual-perceptual formatted and executive versus delayed memory neuropsychological measures in bilingual adults.

METHODS

Data from 55 bilingual, conversationally fluent, neurologically intact, Mexican American, consecutive, adults tested in separate sessions in Spanish and English in a counterbalanced order were analyzed. Age, years of education, self-reported language proficiency, Woodcock-Muñoz Language Survey-Revised (WMLS-R) picture vocabulary measures of language proficiency, and dominance (absolute Spanish-English WMLS-R difference scores) were correlated with 11 measures from La Batería Neuropsicólogica en Español and its original English language tests.

RESULTS

Self-reported and WMLS-R measures of language proficiency were significantly correlated in each language. Absolute language dominance was not significantly associated with any Spanish or English neuropsychological raw score. The WMLS-R language proficiency, but not age or years of education, was significantly correlated with language-formatted neuropsychological measures of California Verbal Learning Test delayed free recall number of words (both languages), letter fluency (both languages), delayed story memory (in English), and Stroop interference (Spanish). Linear regression models using age, years of education, and WMLS-R picture vocabulary scores as predictors were significant for all these measures excepting the last. The WMLS-R language proficiency was not significantly associated with raw scores on any visual-perceptual formatted measure.

CONCLUSIONS

Monolingual neuropsychological test norms for language-formatted tests likely overestimate bilingual Mexican Americans' performance.

Emotion Understanding in Bilingual Preschoolers

The effects of bilingualism on child development have been extensively examined in last decades. Research reveals that simultaneous use of two or more languages affects child's language development, cognitive and social skills. The current study focuses on the so-far understudied theory of emotion understanding in bilingual children. A cohort of 593 bilingual and monolingual 5-6-year-olds took the Russian version of the Test of Emotion Comprehension (TEC) that assesses three components of emotion understanding: emotion understanding of external causes of emotions, reflective causes of emotions; and mental causes of emotions. Our results revealed no group differences between overall emotion understanding and understanding of external and reflective causes of emotions. However, monolingual children had a slightly better understanding of mental causes of emotions compared to bilingual children, when controlling for age, gender, and non-verbal intelligence. These results suggest that children growing up in bilingual environments might require more time and/or language/culture exposure to master the ability to understand mental causes of emotions, taking into account cultural differences, as well as the semantic and lexical differences in emotion labelling and emotion expression in each language.

Reasoning Abilities and Potential Correlates Among Jordanian School Children

Objectives To investigate factors related to reasoning skills in 434 school children aged 5-9 years. Methods The Leiter International Performance Scale-Revised was used to assess reasoning skills. Demographic, work and family income data, information on child's daily behavior and school academic achievement were provided by the participating children's parents. Results Reasoning scores increased by 4.56 points with increasing subject's age, 1.71 points with increasing level of father's occupation, 1.86 points with each increase in the subject's GPA, 1.13 points with consumption of breakfast at home and 1.81 points when child slept more hours. Having a father who smoked and living in a rural area decreased scores in reasoning. Conclusions for Practice Screening of reasoning and associated factors is essential for a comprehensive and accurate understanding of the child's abilities and limitations. Understanding the child's reasoning abilities is critical for establishing intervention goals and planning therapeutic activities.

A Case of Bariatric Surgery-related Wernicke-Korsakoff Syndrome with Persisting Anterograde Amnesia

Objective

To describe the theoretical and clinical implications of the neuropsychological evaluation of a case of bariatric surgery-related Wernicke-Korsakoff syndrome.

Method

The patient was a 37-year old, female, bilingual, bachelor's degree educated, Mexican American public relations consultant without preexisting psychiatric, neurological, or substance abuse history. Recovery from laparoscopic sleeve gastrectomy surgery for morbid obesity was complicated by intraabdominal abscess, multibacterial infection, and prolonged nausea and vomiting. About 15 weeks post-surgery she was diagnosed with Wernicke's encephalopathy. She had a positive response to thiamine supplement but was left with persisting self-reported memory problems that were confirmed by family members. Multiple neuroimaging studies were all normal.

Results

A neuropsychological evaluation at 14 months post-surgery revealed anterograde amnesia for verbal and visual-perceptual material. There was no clear period of temporally graded retrograde amnesia. Scores on tests of visual-perceptual, language, fine motor, and executive functions were unimpaired. She had awareness of her neurocognitive impairment, but did not exhibit emotional distress. Follow-up neuropsychological evaluation at 17 months showed a similar neurocognitive profile with increased emotional distress.

Conclusions

Her preserved executive functioning is theoretically important as it supports arguments that such impairment in alcohol use-related Korsakoff syndrome derives from the toxic effects of the prolonged misuse of alcohol and not vitamin deficiency. From a clinical perspective, neuropsychological evaluation of thiamine treated, bariatric surgery-related, Wernicke's encephalopathy cases is indicated if there is suspicion of residual memory impairment.
