Beliefs about aging are grounded in social experience. This study considered the extent to which married older adults' shared beliefs about aging and markers of aging maintain a concurrent and enduring association with their partners' beliefs about and markers of aging. Data from the 2010/2012 and 2014/2016 waves of the Health and Retirement Study provided measures of husbands' and wives' (3,779 couples) positive and negative beliefs about aging and internal (Cystatin C) and external (grip strength) markers of aging at 2 time points. Latent dyadic models parsed beliefs and markers into partners' individual and shared variances, which were connected both cross-sectionally and longitudinally. Longitudinal analysis showed that the cross-sectional associations between shared beliefs and markers of aging were stable over 4 years. Partners' shared beliefs and markers of aging were found to have enduring associations with each other over time. The enduring association between grip strength and future negative beliefs remained significant after accounting for partner selection and similarity in health. Model comparisons across marriage duration and emotional closeness showed partners' beliefs to be more similar in marriages that were either long established or emotionally close. In all groups, shared beliefs and markers of aging were associated with each other over time. The association between positive beliefs and future grip strength was stronger in long-established than in recent marriages. In summary, this study provides evidence that, within older couples, beliefs about aging are shaped in part through experiences of aging together.

He also examines the impacts of ADHD and stimulant medication on his career, education, and personal life, as well as the impacts of individual and systemic mental health stigma on mental health care providers as prosumers.

A sample of 286 employees during 4 weeks of data was used (N occasions = 1,144). Results of latent class growth modeling showed that 3 trajectories could be identified a nonbullying trajectory, which comprised 90.9% of the sample; an inverted U trajectory; and a delayed increase bullying trajectory; the latter two each had 4.2% of the participants. We found a significant interaction between time and trajectories when predicting insomnia and anxiety/depression, with each strain showing a differential pattern with each trajectory. It seems that the negative effects on insomnia are long-lasting and remain after bullying has already decreased. In the case of anxiety and depression, when bullying decreases strain indicators also decrease. In this study, by examining trajectories of bullying at work over time and their associations with strain, we provide new insights into the temporal dynamics of workplace bullying.

Sexual dimorphisms in behavioral control by the mesolimbic dopaminergic reward system may underlie these phenomena, given its sensitivity to gonadal hormones. However, this is hard to test experimentally using humans. Using the rat gambling task (rGT), we investigated what impact acute inhibition of accumbal dopamine had on decision-making and impulsivity in animals of both sexes. We expressed an inhibitory designer receptor exclusively activated by designer drugs (hM4D[Gi]) in the accumbal dopaminergic efferents of female and male transgenic (Tg) rats, engineered to selectively express cre recombinase in neurons synthesizing tyrosine hydroxylase. We then trained the rats to perform the rGT and assessed the effect of an acute clozapine-n-oxide (0-3 mg/kg) challenge. Chemogenetic inhibition of dopaminergic projections to the accumbens did not affect choice in females, perhaps due to low levels of risky choice in Tg+ animals at baseline, but induced a switch from risky to optimal decision-making in males performing the cued rGT. This manipulation also decreased motor impulsivity but only in females. These data support the hypothesis that cue-driven risky choice is mediated, at least in males, by activity of accumbal dopaminergic neurons. However, motor impulsivity is more sensitive to inhibition of accumbal dopamine neurons in female rats. These data may help explain differences in the manifestation of addictions across gender and reinforce the importance of examining both sexes when seeking to attribute control of behavior to specific monoaminergic pathways.

Although studies of conditioned freezing have consistently demonstrated a role for the hippocampus in renewal, several studies have demonstrated intact renewal of conditioned suppression despite damage to the hippocampus (Frohardt, Guarraci, & Bouton, 2000; Todd, Jiang, DeAngeli, & Bucci, 2017; Wilson, Brooks, & Bouton, 1995). Because these prior studies have examined renewal when testing occurred in the original conditioning context ("Context A"), the present conditioned suppression experiments examined the role of the hippocampus when testing occurred in a context not associated with prior conditioning ("Context C"). In Experiments 1 and 2, conditioning occurred in Context A, and extinction in Context B. Danicamtiv Renewal of conditioned suppression was observed when the extinguished conditioned stimulus (CS) was tested in Context C. However, renewal was attenuated in rats with lesions of the dorsal hippocampus (DH).
