Children's inhibitory control, which refers to the capability to recognize social and task demands by suppressing inappropriate behavior, is a key element closely related to both external and internal issues in preschoolers. The protective roles of parenting factors and social and moral functions, such as gratitude, remain unknown in the mechanism of inhibitory control. The present study employed a general cross-lagged panel model to explore the relationships between positive parenting, child gratitude, and inhibitory control. The research design involved repeated measurements based on parents' reports on 373 Chinese preschoolers in Hong Kong (179 males, 182 females; Mage = 4.51, SD = 0.60). The cross-lagged panel model revealed that positive parenting at Time 1 (T1) was significantly associated with preschool children's gratitude but not with inhibitory control at Time 2 (T2). Conversely, child gratitude at T1 was positively associated with inhibitory control at T2. These findings underscore the impact of positive parenting on gratitude and the predictive role of gratitude on inhibitory control. [ABSTRACT FROM AUTHOR]

Few studies have explored meaning in life as a mediator between adverse childhood experiences (ACEs) and mental health. This study examined the protective and risk factors associated with meaning in life, as they mediate the effect of ACEs on mental health. The sample was 293 university students in Hong Kong (mean age = 21 years). The results of analyses based on three‐wave longitudinal data and structural equation modeling demonstrated that the presence of meaning mediated the negative association between ACEs and happiness, and that meaning confusion mediated the positive association between ACEs and depression and anxiety. This study provides evidence that the presence of meaning may play a protective role and that meaning confusion may be a risk factor for the effects of ACEs on mental health. This study's results have implications for the development of prevention and intervention strategies to alleviate the detrimental impact of ACEs and promote mental health in young adults.

In most complex nervous systems there is a clear anatomical separation between the nerve cord, which contains most of the final motor outputs necessary for behaviour, and the brain. In insects, the neck connective is both a physical and information bottleneck connecting the brain and the ventral nerve cord (VNC, spinal cord analogue) and comprises diverse populations of descending (DN), ascending (AN) and sensory ascending neurons, which are crucial for sensorimotor signalling and control. Integrating three separate EM datasets, we now provide a complete connectomic description of the ascending and descending neurons of the female nervous system of Drosophila and compare them with neurons of the male nerve cord. Proofread neuronal reconstructions have been matched across hemispheres, datasets and sexes. Crucially, we have also matched 51% of DN cell types to light level data defining specific driver lines as well as classifying all ascending populations. We use these results to reveal the general architecture, tracts, neuropil innervation and connectivity of neck connective neurons. We observe connected chains of descending and ascending neurons spanning the neck, which may subserve motor sequences. We provide a complete description of sexually dimorphic DN and AN populations, with detailed analysis of circuits implicated in sex-related behaviours, including female ovipositor extrusion (DNp13), male courtship (DNa12/aSP22) and song production (AN hemilineage 08B). Our work represents the first EM-level circuit analyses spanning the entire central nervous system of an adult animal.
