标题：Straight From the Scientist’s Mouth—Plain Language Summaries Promote Laypeople’s Comprehension and Knowledge Acquisition When Reading About Individual Research Findings in Psychology
摘要：Easily comprehensible summaries of scholarly articles that are provided alongside ‘ordinary’ scientific abstracts, so-called plain language summaries, can be a powerful tool for communicating research findings to a wider audience. Using an experimental within-person-design in a preregistered study (N = 166), we showed that the comprehensibility for laypeople was higher for plain language summaries compared to scientific abstracts in a psychological journal and also found that laypeople actually understood the corresponding information more correctly for plain language summaries. Moreover, in line with the easiness effect of science popularization, individuals perceived plain language summaries as more credible and were more confident about their ability to make a decision based on plain language summaries. If and under which circumstances this higher perceived credibility is justified, is discussed together with other practical implications and theoretical implications of our findings. In sum, our research further strengthens arguments for providing plain language summaries of psychological research findings by demonstrating that they actually work in practice.
