Objective:
Individuals tend to overestimate their abilities in areas where they are less competent. This cognitive bias is known as the Dunning-Krueger effect. Research shows that Dunning-Krueger effect occurs in persons with traumatic brain injury and healthy comparison participants. It was suggested by Walker and colleagues (2017) that the deficits in cognitive awareness may be due to brain injury. Confrontational naming tasks (e.g., Boston Naming Test) are used to evaluate language abilities. The Cordoba Naming Test (CNT) is a 30-item confrontational naming task developed to be administered in multiple languages. Hardy and Wright (2018) conditionally validated a measure of perceived mental workload called the NASA Task Load Index (NASA-TLX). They found that workload ratings on the NASA-TLX increased with increased task demands on a cognitive task. The purpose of the present study was to determine whether the Dunning-Kruger effect occurs in a Latinx population and possible factors driving individuals to overestimate their abilities on the CNT. We predicted the low-performance group would report better CNT performance, but underperform on the CNT compared to the high-performance group.
Participants and Methods:The sample consisted of 129 Latinx participants with a mean age of 21.07 (SD = 4.57). Participants were neurologically and psychologically healthy. Our sample was divided into two groups: the low-performance group and the high-performance group. Participants completed the CNT and the NASA-TLX in English. The NASA-TLX examines perceived workload (e.g., performance) and it was used in the present study to evaluate possible factors driving individuals to overestimate their abilities on the CNT. Participants completed the NASA-TLX after completing the CNT. Moreover, the CNT raw scores were averaged to create the following two groups: low-performance (CNT raw score <17) and high-performance (CNT raw score 18+). A series of ANCOVA's, controlling for gender and years of education completed were used to evaluate CNT performance and CNT perceived workloads.
Results:We found the low-performance group reported better performance on the CNT compared to the high-performance, p = .021, np2 = .04. However, the high-performance group outperformed the low-performance group on the CNT, p = .000, np2 = .53. Additionally, results revealed the low-performance group reported higher temporal demand and effort levels on the CNT compared to the high-performance group, p's < .05, nps2 = .05.
Conclusions:As we predicted, the low-performance group overestimated their CNT performance compared to the high-performance group. The current data suggest that the Dunning-Kruger effect occurs in healthy Latinx participants. We also found that temporal demand and effort may be influencing awareness in the low-performance group CNT performance compared to the high-performance group. The present study suggests subjective features on what may be influencing confrontational naming task performance in low-performance individuals more than highperformance individuals on the CNT. Current literature shows that bilingual speakers underperformed on confrontational naming tasks compared to monolingual speakers. Future studies should investigate if the Dunning-Kruger effects Latinx English monolingual speakers compared to Spanish-English bilingual speakers on the CNT.

Objective:
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.
Participants and Methods: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: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.
Conclusions: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.

Objective:
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.
Participants and Methods: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.
Results: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.
Conclusions: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.

Objective:
The research examining the influence of bilingualism on cognition continues to grow. Past research shows that monolingual speakers outperformed bilingual speakers on language, memory, and attention and processing speed tasks. However, the opposite has been found favoring bilingual speakers, when comparing executive functioning abilities. Furthermore, researchers have reported that no differences in executive functioning abilities exist between young adult monolingual speakers compared to young adult bilingual speakers. Moreover, limited research exists examining cognition abilities between monolinguals, bilinguals that learn a language (e.g., English) first, and bilinguals that learn the same language (e.g., English) second. We examined young adult monolinguals cognition abilities (e.g., memory) compared to young adult bilinguals that learned English as a first or second language. It was expected that the monolingual group would outperform both bilingual groups on memory, language, and attention and processing tasks, but no differences would be found on executive functioning tasks.
Participants and Methods:The sample consisted of 149 right-handed undergraduate students with a mean age of 19.58 (SD = 1.90). Participants were neurologically and psychologically healthy and divided into three language groups: English first language (EFL) monolingual speakers, EFL bilingual speakers, and English second language (ESL) bilingual speakers. All the participants completed a background questionnaire and comprehensive neuropsychological battery that included memory, language, executive functioning, and attention and processing speed tasks in English. A series of ANOVA’s were used to evaluate cognitive tasks (e.g., Boston Naming Test, Trail Making Test) between the language groups. Participants demonstrated adequate effort on one performance validity test.
Results:Language groups were well demographically matched. We found the EFL monolingual group outperformed the ESL bilingual group on the Wide Range Achievement Test, fourth edition task and the Controlled Oral Word Association Test (COWAT) phonemic task, p’s < .05, np’s2 = .04-.05. Additionally, results revealed both monolingual groups outperformed the ESL bilingual group on the Wechsler Adult Intelligence Scale, Third edition vocabulary task and the Boston Naming Test, p’s < .05, np’s2 = .06-.15. No significant differences were found on any of the cognitive tasks between the EFL monolingual group and the EFL bilingual group.
Conclusions:As expected, the ESL bilingual group performed worse on language tasks compared to both monolingual groups, specifically the EFL monolingual group. However, in the opposite direction, we found the EFL monolingual demonstrated better phonemic verbal fluency abilities on the COWAT compared to the ESL bilingual group. The current data suggest that bilingualism influences cognitive abilities (e.g., language, executive functioning) more ESL bilingual speakers compared to EFL monolingual speakers. A possible explanation may be due to the type of interaction that ESL bilingual speakers may prefer to have (i.e., mix language conversations) compared to EFL speaking groups. Future studies with a larger bilingual speaking sample should investigate if the Adaptive Control Hypothesis which suggest that different types of conversations may be placing different demands of language control influences cognitive abilities.

This study focused on the associations between parental divorce and interparental conflict with young adults’ current attachment-related anxiety and avoidance, and romantic relationship expectations. The moderating effect of attachment history was also investigated. Using a sample of 1,078 Spanish young adults (544 women, 518 men; average age 21.4 years), our results confirmed that parental divorce is not associated with young adult children’s higher attachment anxiety and avoidance nor poorer romantic relationship expectations. Moreover, interparental conflict is more strongly associated with attachment-related avoidance (p < .001) and romantic relationship expectations (p < .05) than parental divorce, yet depending on attachment history. In fact, in support of our hypothesis, a more secure attachment history with mother has a buffering effect on the association between high-unresolved interparental conflict and attachment avoidance (β = .17, p < .001). Findings add to the existing literature and promote a better understanding of the complex associations between parental divorce and conflict on adult children´s current attachment and relationship expectations.

Glycogen storage diseases (GSDs) result from the deficiency of enzymes involved in glycogen synthesis and breakdown into glucose. Mutations in the gene PHKA2 encoding phosphorylase kinase regulatory subunit alpha 2 have been linked to GSD type IXa. We describe a family with two adult brothers with neonatal hepatosplenomegaly and later onset of hearing loss, cognitive impairment, and cerebellar involvement. Whole-exome sequencing was performed on both subjects and revealed a shared hemizygous missense variant (c.A1561G; p.T521A) in exon 15 of PHKA2. The phenotype broadens the clinical and magnetic resonance imaging spectrum of GSD type IXa to include later onset neurological manifestations.

Summary
Abstract
Past research has demonstrated that severe economic downturns can have a major impact on the life course, and the Great Recession is unlikely to be an exception. Of particular interest is the potential for the Great Recession to reshape a period of the life course that is the focus of a great deal of discussion and concern: the transition into adulthood. Here, we draw on life course theory to describe the ways in which the assumption of various work, educational, and family roles in the late teens and early twenties may have been sped up or slowed down by the Great Recession and how these apparent recession effects may have varied according to the family backgrounds and psychological/behavioral capacities of young adults. Historical comparisons of multiple cohorts (2004, 2006, 2008, 2010) of US young adults who participated in the National Longitudinal Survey of Youth – Young Adult cohort revealed some evidence that transitioning into adulthood during the Great Recession slowed down school enrollment, labor force entry, partnering, and becoming a parent among 18–25-year-olds. The prevalence of these statuses was often especially low in the supposed recovery year of 2010, and school enrollment was the least affected status. This slow-down was more age group-specific for family roles. Variation in these cohort trends by family background and psychological/behavioral factors was minimal, although some evidence suggested that a history of high academic achievement may have done more to delay family transitions among teenagers during the Great Recession. Comparisons with historical trends in young adult statuses in Brazil, Mexico, and South Korea provide useful context for these US patterns.
Introduction
Today, media stories about the possibility of a “lost generation” reflect fears about youth coming of age during the Great Recession, particularly young people in their late teens and early twenties who are trying to find a foothold in adulthood in a time of foreclosed opportunity (Grusky, Western, and Wimer 2012). These fears are certainly not unfounded, given past research showing that young adults are vulnerable during economic downturns because they are too old to be protected from the reality of what is happening and too young to have already secured foundational school and work experiences.
