Word and name retrieval failures increase with age, and this study investigated how priming impacts young and older adults' ability to produce proper names. The transmission deficit hypothesis predicts facilitation from related prime names, whereas the blocking and inhibition deficit hypotheses predict interference from related names, especially for older adults. On half of our experimental trials, we exposed participants to a prime name that is phonologically- and semantically-related to a target name. Related names facilitated production of targets overall, with older adults' naming ability improved at least as much as young adults'. Results are contrary to predictions of the blocking and inhibitory deficit hypotheses, and suggest that an activation-based model of memory and language better accounts for retrieval and production of well-known names.

While the direct health impacts of air pollution are widely discussed, its indirect effects, particularly during pandemics, are less explored. Utilizing detailed individual-level data from all designated hospitals in Wuhan during the initial COVID-19 outbreak, we examine the impact of air pollution exposure on treatment costs and health outcomes for COVID-19 patients. Our findings reveal that patients exposed more intensively to air pollution, identified by their residence in downwind areas of high-polluting enterprises, not only had worsened health outcomes but also consumed more medical resources.

Background: Obesity could compromise people's health and elevate the risk of numerous severe chronic conditions and premature mortality. Young adults are at high risk of adopting unhealthy lifestyles related to overweight and obesity, as they are at a phase marked by several significant life milestones that have been linked to weight gain. They gain weight rapidly and excess adiposity mostly accrues, compared with middle-aged and older adults when weight stabilizes or even decreases.
