Smoking mediates the effect of conscientiousness on mortality: The Veterans Affairs Normative Aging Study

This study examined the relationship between conscientiousness and mortality over 18 years and whether smoking behavior mediated this relationship. We utilized data from the Veterans Affairs Normative Aging Study on 1349 men who completed the Goldberg (1992) adjectival markers of the Big Five. Over the 18-year follow-up, 547 (41%) participants died. Through proportional hazards modeling in a structural equation modeling framework, we found that higher levels of conscientiousness significantly predicted longer life, and that this effect was mediated by current smoking status at baseline. Methodologically, we also demonstrate the effectiveness of using a structural equation modeling framework to evaluate mediation when using a censored outcome such as mortality.     

Gender Categories as Dual-Character Concepts?

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual-character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual-character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual-character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual-character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual-character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual-character-like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow-up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored.     

From a terror management perspective: The efficacy of self-affirmation on organ donation-related thoughts and intentions in China

ABSTRACT

In 2015, the Chinese government officially abolished the practice of harvesting organs from executed prisoners. However, the voluntary donor registration rate among the Chinese population is approximately 2% as of January 2020. Guided by self-affirmation theory and terror management theory, the present investigation examined a number of variables that may be related to donor registration intentions and a method to mitigate death thoughts and misconceptions. An online experiment was conducted in which 352 Chinese participants were randomly assigned to either a self-affirmation (i.e., affirming values that are important to the participants) or a no-affirmation condition. Results revealed that self-affirmation lowered death thoughts among the participants, which in turn were positively related to organ donation misperceptions. Inconsistent with terror management theory, the level of death thoughts was not directly related to participants’ intentions to register as organ donors. Instead, the relationship between the two was mediated by misperceptions toward organ donation.
