This project is situated within the field of cognitive psychology, specifically examining the credibility assessment of online videos by secondary school students (from grades 6 to 12) and young adults (undergraduate students). The study pursues two primary objectives. First, it aims to evaluate students' critical thinking skills, specifically regarding sourcing and information evaluation, when processing video content. Second, we seek to identify the individual cognitive dispositions (i.e., prior knowledge about climate change, epistemic curiosity, need for closure, belief in science) that may influence video evaluation. The stimuli focus on the topic of electric vehicles, a contemporary socio-scientific issue related to sustainable development that is highly susceptible to controversy and misinformation.
