What kind of scenes did participants view in the Canli study?

In the Canli study, participants viewed both neutral and negative scenes. This variety is essential because the study aimed to investigate the relationship between emotional arousal and memory retention. By including negative scenes—known to provoke a stronger emotional response—alongside neutral scenes, the researchers could explore how different levels of emotional content impacted memory recall. The presence of neutral scenes served as a control to help compare responses and memory retrieval between arousing and non-arousing stimuli. This design is crucial for understanding how emotional experiences influence cognitive processes, particularly memory, thereby providing insights into how our emotions can enhance or impair our ability to remember information.
