We developed a multiple-form list learning test appropriate for use with the Greek population and generated norms for clinical and research use. This task, the Greek Verbal Learning Test (GVLT), was based on the California Verbal Learning Test. We administered the standard version (Form A) to a sample of 354 healthy individuals, as well as two alternative forms (B and C) to a subgroup of the initial sample. Performance on the three forms was equivalent, and each test presented excellent internal consistency. We found good sensitivity and specificity in the testãs (Form A) utility in differentiating individuals with schizophrenia (n = 50) and individuals with traumatic brain injury (n = 53) from healthy adults. A multiple regression analysis indicated that age, education and sex predicted performance. Regression-based norms are also provided. Taken together, these data provide preliminary support for the reliability and construct validity of the GVLT.
Objective:
Maternal anxiety is a well-known risk factor for early childhood behavior problems. In this study, we explore (1) whether parenting stress mediates this relation and also (2) whether child factors, namely self-regulation, modify the influence of maternal well-being on child externalizing and internalizing problems at 4 years of age.
Method:
Mothers taking part in the Growing Up in Singapore Towards Healthy Outcomes cohort completed the Spielberger State-Trait Anxiety Inventory when their children were 24 months of age. At 42 months of age, children performed a self-regulation task (n = 391), and mothers completed the Parenting Stress Index. When children were 48 months old, both parents completed the Child Behavior Checklist.
Results:
As predicted, parenting stress mediated the relation between maternal trait anxiety and child externalizing and internalizing problems. This mediating effect was further moderated by child self-regulation. The indirect effect of maternal trait anxiety through parenting stress on child externalizing problems was stronger among children with low self-regulation.
Conclusion:
Parenting stress is an additional pathway connecting maternal trait anxiety and children's externalizing and internalizing behavior problems. The risk for child externalizing problems conveyed by elevated maternal trait anxiety and parenting stress may be buffered by better self-regulation in 4-year-olds. These results suggest that interventions that include decreasing parenting stress and enhancing child self-regulation may be important to limiting the transgenerational impact of maternal trait anxiety.
From a conditional adaptation vantage point, early life caregiving adversity likely enhances aspects of cognition needed to manage interpersonal threats. Yet, research examining early life care and offspring cognition predominantly relies upon experiments including affectively neutral stimuli, with findings generally interpreted as “early-life caregiving adversity is, de facto, ‘bad’ for cognitive performance.” Here, in a Southeast Asian sample, we examined observed maternal sensitivity in infancy and cognitive performance 3 years later as preschoolers took part in three tasks, each involving both a socioemotional (SE) and non-socioemotional (NSE) version: relational memory (n = 236), cognitive flexibility (n = 203), and inhibitory control (n = 255). Results indicate the relation between early life caregiving adversity and memory performance significantly differs (Wald test = 7.67, (1), P = 0.006) depending on the SE versus NSE context, with maternal sensitivity in infancy highly predictive of worse memory for SE stimuli, and amongst girls, also predictive of better memory when NSE stimuli are used. Results concerning inhibitory control, as well as cognitive flexibility in girls, also tentatively suggest the importance of considering the SE nature of stimuli when assessing relations between the caregiving environment and cognitive performance. As not all approaches to missing data yielded similar results, implications for statistical approaches are elaborated. We conclude by considering how an adaptation-to-context framework approach may aid in designing pedagogical strategies and well-being interventions that harness pre-existing cognitive strengths.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
