The catcher in the lie: The role of emotions and epistemic judgments in changing students’ misconceptions and attitudes in a post-truth era

We extend previous theoretical and empirical work by examining the role that emotions and epistemic judgments play when learning from different refutation plus persuasive and expository plus persuasive texts. We examined how variations in messages designed to change misconceptions and attitudes about genetically modified foods (GMFs) might differentially impact the extent to which individuals engage in epistemic judgments; the emotions individuals experience during learning; and, how epistemic judgments and emotions might facilitate or constrain conceptual and attitudinal change. One hundred twenty-five undergraduate university students were randomly assigned to one of four text conditions: refutation plus positive persuasive text, refutation plus negative persuasive text, expository plus positive persuasive text, or expository plus negative persuasive text. Students were asked to think and emote out loud during learning to capture epistemic judgments and emotions as they occurred in real time. After the learning session, students also self-reported the emotions they experienced during learning. Results revealed that students who were given positive persuasive texts experienced more positive emotions (both intensity and frequency) during learning, whereas those who were given negative persuasive texts experienced more negative emotions (frequency) during learning. Students who were given positive persuasive texts engaged in more epistemic judgments and changed more misconceptions about GMFs compared to students in the other three text conditions. Finally, epistemic judgments were significant positive predictors of conceptual and attitudinal change, and both positive emotions and negative emotions predicted attitudinal change. Implications for theories of conceptual and attitudinal change are discussed.     

Dealing with disagreement: The roles of topic familiarity and disagreement explanation in evaluation of conflicting expert claims and sources

Learners may increasingly encounter conflicting expert reports. However, little is known about how they deal with this challenge. We examined how learners' familiarity with a controversial historical topic affects their epistemic judgments of conflicting expert claims and sources, the interplay of their claim and source evaluation strategies, and their meta-epistemic understanding of the legitimacy of the disagreement (absolutist, multiplist, and evaluativist perspectives). In two studies, topic familiarity increased agreement with belief-consistent expert claims and the perceived trustworthiness of the expert who presented these claims. Topic familiarity also impacted the coordination of evaluation strategies and led to greater reliance on knowledge-based validation. However, topic familiarity did not affect meta-epistemic understanding of the legitimacy of the controversy. In the second study, reading an explanation about reasons for disagreements between historians resulted in higher evaluativism. Teaching about expert disagreement may be a productive approach for promoting appreciation of the diversity of knowledge.

试析中国国家安全战略的选择

中国制定国家安全战略、国防政策和军事战略的前提，离不开对现阶段国家安全形势和背景的具体的、历史的考证。美国的单边主义和对华遏制、日本的背离和“台独”势力分裂国家的图谋是目前中国国家安全尤其需要重视的因素。因此中国的国家安全战略应是：保证必要的、足够的军事威慑，保持最大范围和最大可能的合作。
