The effects of existential threat on reading comprehension of worldview affirming and disconfirming information

Terror management theory posits that cultural worldviews buffer people from thoughts and concerns about death. In support of this claim, numerous studies have shown that mortality salience (MS) increases an individual's motivation to uphold and defend important cultural worldviews. We hypothesized that the motivation to defend cultural worldviews following MS would also enhance people's ability to comprehend worldview affirming (vs. disconfirming) information. Three studies investigated this possibility. Study 1 showed that MS (vs. control) increased reading comprehension of a pro‐evolution essay among participants with a strongly evolutionist worldview, but decreased reading comprehension among participants with a strongly creationist worldview. With the use of a pro‐creation essay, Study 2 conceptually replicated these effects and demonstrated that the interactive effect of worldview and death anxiety on reading comprehension was mediated by defensive motivation. Study 3 replicated the results of Studies 1 and 2 among participants with a strongly evolutionist worldview, but only when the information in the essay was perceived as veridical. Discussion focused on the specific process through which MS affects reading comprehension of worldview relevant ideas. Copyright © 2012 John Wiley & Sons, Ltd.     

Evidence for the DTA hypothesis II: Threatening self-esteem increases death-thought accessibility

Three studies assessed the impact of self-esteem threat on death-thought accessibility (DTA). Increased DTA resulted from three distinct types of self-esteem threat. Studies 1 and 2 employed negative feedback procedures in which participants were told that they scored below average on an intelligence test (Study 1), or that their personality was incongruent for their desired career path (Study 2). In Study 3, participants were led to believe that they would give an ill prepared speech in front of their peers. In Studies 1 and 2 DTA was assessed via reaction times on a lexical decision task, while Study 3 employed a word-fragment completion task. Study 3 demonstrated the DTA buffering effect of fortifying self-esteem via self-affirmation. Discussion focused on general implications for TMT, self-esteem, and mental health.     

Cultural Blankets: Epistemological Pluralism in the Evolutionary Epistemology of Mechanisms

Journal for General Philosophy of Science - In a recently published paper, we argued that theories of cultural evolution can gain explanatory power by being more pluralistic. In his reply to it,...
