Inhibitory control is thought to play a key role in how bilinguals switch languages and may decline in aging. We tested these hypotheses by examining age group differences in the reversed language dominance effect-a signature of inhibition of the dominant language that leads bilinguals to name pictures more slowly in the dominant than the nondominant language in mixed-language testing blocks. Twenty-five older and 48 younger Spanish-English bilinguals completed a cued language-switching task. To test if inhibition is applied at the whole-language or lexical level, we first presented one set of pictures repeatedly, then introduced a second list halfway through the experiment. Younger bilinguals exhibited significantly greater reversed language dominance effects than older bilinguals (who exhibited nonsignificant language dominance effects). In younger bilinguals, dominance reversal transferred to, and was even larger in, the second list (compared to the first). The latter result may suggest that inhibition is partially offset by repetition in ways that are not yet fully understood. More generally, these results support the hypotheses that aging impairs inhibitory control of the dominant language, which young bilinguals rely on to switch languages. Additionally, inhibition is applied primarily at the whole-language level, and speculatively, this form of language control may be analogous to nonlinguistic proactive control.

Associations between (a) marital status at study baseline (currently married, previously married, never married) and (b) retrospectively reported life course marital biography (i.e., age at first marriage, time spent unmarried following initial marriage, history of divorce, history of widowhood) and up to 20 years of subsequent episodic memory trajectories were examined using latent growth curve models in 3,061 participants aged 51 + in the Health and Retirement Study 2017 Life History Mail Survey. Gender differences were examined with multiplicative interaction terms and stratified models. Participants who were married at study baseline demonstrated higher initial memory than previously and never married individuals. Older age at first marriage and shorter duration spent unmarried were each associated with better initial episodic memory among previously married individuals only; longer duration spent unmarried was associated with slower memory decline. Stratified models suggested that these associations may be driven by women. These results highlight the importance of considering multiple aspects of marital biography, not just current marital status, in cognitive aging research. Marital biography may have an enduring influence on cognitive aging, particularly among previously married older women. Future work is needed to identify mechanisms (e.g., socioeconomic resources, cognitive stimulation, self and spousal health, emotional support) through which marital histories influence cognitive aging.

Here we examined to what extent prospectively assessed child abuse and neglect is associated with self-reported symptoms of psychopathology measured from ages 23 through 39 years, controlling for early demographic covariates and self-reported symptoms of psychopathology measured at age 16 years. The sample included 140 participants from the Minnesota Longitudinal Study of Risk and Adaptation. Participants were 49% female and 69% White/non-Hispanic. At the time of their child's birth, 48% of the mothers were teenagers (M = 20.5 years, SD = 3.74), 65% were single, and 42% had completed less than a high school education. Results indicated that childhood abuse and neglect was robustly associated with symptoms of psychopathology in adulthood. Exploratory analyses focusing on specific parametrizations of abuse/neglect suggested that abuse perpetrated by maternal figures (rather than paternal or nonparental figures) was uniquely associated with high levels of self-reported symptoms of psychopathology in adulthood. We found no evidence that any subtype of abuse and/or neglect or abuse/neglect during any particular phase of development uniquely predicted symptoms of psychopathology after controlling for relevant covariates. These results highlight the long-lasting significance of childhood abuse and neglect for reports of mental health in adulthood.

However, this model has not been empirically tested in predicting the development of shyness. In two separate longitudinal studies, we used the Carver and White (1994) Behavioral Inhibition and Activation System (BIS/BAS) scales as a proxy of approach-avoidance motivations and growth curve analyses to examine whether individual differences in these hypothesized motivational tendencies were associated with the development of shyness across 3 years from late childhood to adolescence (Study 1, N = 1284; 49.8% female, Mage = 10.72, SDage = 1.73, M level of parental education fell between associate's degree/diploma and undergraduate degree) and across nearly a decade from emerging adulthood to young adulthood (Study 2, N = 83; 57.8% females, Mage = 23.56 years, SDage = 1.09 years, 92.8% had at least a high school education). Contrary to the approach-avoidance conflict model of shyness, we found that a combination of high BIS/low BAS, not high BIS/high BAS, was associated with relatively higher shyness contemporaneously and across development in both studies. We discuss the processes that might link individual differences in approach-avoidance motivations to the development of shyness in adolescence and young adulthood.
