We investigated whether children prefer feedback over stated probabilistic information in decision making. 6-year-olds', 9-year-olds', and adults' making was examined in an environment where probabilistic information about choice outcome had to be actively searched ( = 166) or was available without search ( = 183). Probabilistic information was provided before choices as predictions of cues differing in validity. The presence of outcome feedback was varied. 6-year-olds, but not 9-year-olds were over-responsive to negative outcomes leading to choices biased by recent feedback. However, children did not systematically utilize feedback in choices. Irrespective of feedback, 6-year-olds fully and 9-year-olds partly neglected stated probabilistic information in their choices. When 6-year-olds chose systematically, they only relied on invalid information, which did not maximize outcomes. 9-year-olds still applied invalid choice rules, but also choice rules based on probability. Results suggest that neglect of probabilities in complex decisions is robust, independent of feedback, and only starts to subside at elementary school age.

Visceral leishmaniasis (VL) is a neglected tropical disease that mostly affects the working-class and impoverished segments of society, having a significant negative effect on the economic development of the affected nation. While anti-leishmanial medications lower mortality among VL patients, patients may still die or require more time to recover (TTR) while receiving treatment. In this regard, there are limited studies in Ethiopia.

Introduction: A growing body of research indicates that being incarcerated in an adult jail or prison as a juvenile can elevate one's exposure to adverse childhood experiences, including violent and sexual victimization and neglect, and may lead to several long-term difficulties. This study investigates the relationship between being confined in an adult jail or prison as a minor and experiencing violent victimization as an adult.
Methods: Data from the National Longitudinal Survey of Youth-1997 cohort were used in the study.

Efforts to prevent dementia can benefit from precision interventions delivered to the right population at the right time; that is, when the potential to reduce risk is the highest. Young adults (aged 18-39 years) are a neglected population in dementia research and policy making despite being highly exposed to several known modifiable risk factors. The risk and protective factors that have the biggest effect on dementia outcomes in young adulthood, and how these associations differ across regions and groups, still remain unclear.
