ABSTRACT
What role do financial worries play in close relationship functioning? In this research, we examine how financial worry - negative thoughts and feelings about finances - is associated with perceived relationship behaviors. Participants recalled how their partner acted during a recent disagreement (Study 1, N = 97 couples) or recalled the frequency of positive and negative behaviors enacted by their partner during the previous week (Study 2, N = 99 couples). Feeling more worried about finances was associated with recalling less supportive behavior from one's partner at the disagreement (Study 1) and with perceiving more negative behaviors from one's partner in the last week (Study 2). Truth and Bias Model analyses suggest that part of this link may be attributed to biased perceptions, as the link between financial worry and perceiving more negative behaviors persisted even after controlling for participants' own reported behaviors (i.e., accounting for similarity) and for their partner's own reported behaviors (i.e., accounting for accurate perceptions). In sum, financial worry is linked to how partners notice and interpret a loved one's actions within their relationship.
ABSTRACT
This study aimed to systematically investigate the relationship between bilingualism, age, L2 onset age of acquisition (AoA), and white matter integrity (operationalized as fractional anisotropy, FA), addressing inconsistencies in the literature. We conducted a meta-analysis of 23 studies and used meta-regression models to assess the influence of age and L2AoA on effect sizes in studies comparing monolinguals and bilinguals. Even though the overall between-group effect size across the whole brain was unreliable, bilingualism was associated with increased white matter integrity in specific tracts and in groups with a limited range of age and L2AoA. Age had a small, negative effect on white matter integrity, with differences between monolinguals and bilinguals more pronounced in younger adults, consistent with a view of an initial increase in white matter integrity, followed by remodeling for efficiency over time. In contrast, later L2AoA was associated with greater white matter integrity in bilinguals than monolinguals, again consistent with the remodeling for efficiency model. Our findings highlight the importance of considering age and L2AoA when examining the neural basis of bilingualism on white matter in the brain and how bilingualism contributes to structural changes that stave off cognitive decline in older age.
