Associations between young adult romantic relationship quality and problem behaviors: An examination of personality–environment interactions

This longitudinal study examined person–environment interplay by testing interaction effects between adolescent personality type (i.e., overcontrollers, undercontrollers, and resilients) and young adult romantic relationship quality on young adult delinquency and anxiety. The study employed six waves of longitudinal questionnaire data collected across 10 years from Dutch youths. Results showed that support from romantic partner was related to a relatively stronger decrease in anxiety in young adulthood for overcontrollers than for resilients. Moreover, higher negative interaction with romantic partner was related to a relative increase in delinquent behaviors for undercontrollers, while no such links emerged for overcontrollers and resilients. This study highlights the importance of considering the interplay between personality characteristics and environmental–relational factors when examining young adults’ developmental outcomes.     

Learning a new geometric concept: The role of working memory and of domain-specific abilities

It has been suggested that not only domain-specific factors but also working memory (WM) may play a crucial role in mathematical learning included Geometry, but the issue has not been deeply explored. In the present study, we examined the role of domain-specific factors and of verbal versus visuospatial WM on geometric learning of a new geometrical figure (trapezoid), never presented previously by the teachers participating to the study, after a lecture also involving manipulatives. Results on 105 children in their Year 4 indicated that not only some domain-specific components (geometric declarative knowledge and calculation) but also visuospatial working memory had a significant specific impact on the ability of solving geometric problems requiring to calculate the perimeter and the area of the new figure. On the contrary, verbal WM and geometrical mental imagery did not offer a specific contribution. These findings could have important educational implications, stressing the importance of taking into account the main different aspects supporting the acquisition of geometry.     

The impact of the home musical environment on infants’ language development

There is strong evidence that musical engagement influences children’s language development but little research has been carried out on the relationship between the home musical environment and language development in infancy. The current study assessed musical exposure at home (including parental singing) and language development in 64 infants (8.5–18 months). Results showed that the home musical environment significantly predicted gesture development. For a subgroup of infants’ below 12 months, both parental singing and overall home musical environment score significantly predicted word comprehension. These findings represent the first demonstration that an enriched musical environment in infancy can promote development of communication skills.     

Family play,reading, and other stimulation and early childhood development in five low-and-middle-income countries

This paper used longitudinal data from five studies conducted in Bangladesh, Bhutan, Cambodia, Ethiopia, and Rwanda to examine the links between family stimulation and early childhood development outcomes (N = 4904; M_age = 51.5; 49% girls). Results from random-effects and more conservative child-fixed effects models indicate that across these studies, family stimulation, measured by caregivers’ engagement in nine activities (e.g., reading, playing, singing), predicted increments in children's early numeracy, literacy, social-emotional, motor, and executive function skills (standardized associations ranged from 0.05 to 0.11 SD). Study-specific models showed variability in the estimates, with null associations in two out of the five studies. These findings indicate the need for additional research on culturally specific ways in which caregivers may support early development and highlight the importance of promoting family stimulation to catalyze positive developmental trajectories in global contexts.

Research Highlights

• Research on the links between family stimulation and early childhood development in low-and-middle-income countries (LMICs) is limited.
• We used longitudinal data from studies conducted in five LMICs to examine the links between family stimulation and early childhood development outcomes.
• Results suggest that family stimulation predicted increments in children's numeracy, literacy, social-emotional, motor, and executive function skills.
• We found variability in the observed estimates, with null associations in two out of the five studies, suggesting the need for additional research in LMICs.

     

The influence of the visual surrounding environment in older adults and young adults’ cognitive performance: an alternative paradigm

ABSTRACT

This study investigated how the characteristics of the visual surrounding environment influence older- and young-adults’ cognitive performance. Sixty-four older adults and 64 young adults performed four visual cognitive tasks (attention and memory tasks) in two independent sessions while being exposed to a high-load and a low-load visual surrounding environment. We expected that the high-load environment would hurt the older-adults performance due to typical difficulties in ignoring irrelevant stimuli, whereas no such effect would likely occur for the young-adults whose cognitive abilities are at their best. Overall, our results were consistent with our prediction in three tasks (go/no-go, choice reaction time, and Corsi block-tapping). Additionally, the older adults performed worse than the young adults in all tasks, thus confirming expected age-related differences. Our results are consistent with those obtained when distractors and targets are presented in the same display, now using a paradigm which locates the distractors in the surrounding environment.     

Moulding environmental contexts to optimise neurodiverse executive function performance and development: A goodness-of-fit account

Executive functions (EFs) provide a top-down response to stimuli and events in pursuit of a goal. We argue that the extent to which an individual's environment is enriching and a good fit for them influences whether their performance at that moment is towards their upper- or lower-limit of EF ability. We outline the implications of this for interpreting measures of EF. We next argue that a child's sensitivity to the environment, and their caregivers' ability to modulate the environment to improve goodness-of-fit, influences the cumulative effects of the environment in shaping that child's actualised EF ability (the performance level shown in day-to-day situations), and thus their skill development. We therefore recommend that EF interventions be designed to improve children's actualised EF ability by improving their day-to-day environment, while simultaneously helping children modulate their physiological response to environmental challenges, and providing opportunities to practise EF skills in ecologically-valid contexts.     

The development of Addiction-Prone Personality traits in biological and adoptive families

This project investigated the predictors of Addiction-Prone Personality (APP) scores in youth and young adults from biological (N = 328, 53% female) and adoptive (N = 77, 53% female) families. The development of offspring’s APP traits was examined from three different angles: (1) patterns in biological and adoptive families, (2) offspring’s vs. parent’s perceptions of familial environment, and (3) different points in the life span. The offspring’s APP scores were found to be significantly predicted by parents’ APP scores in both biological and adoptive families. Parents’ APP scores and offspring’s gender consistently showed significant direct influences on offspring’s APP scores in biological families. The familial care factor (maternal and paternal care, family cohesion, and family adaptability) was found to be the consistent significant predictor of offspring’s APP scores in adoptive families even when offspring became older. These results are consistent in showing that the social environment plays an important role in the development of Addiction-Prone Personality traits.
