From hurricanes to homecomings: A database of news broadcast videos for investigating the dynamics of emotional memory

The emotional content of events and experiences can influence the way they are perceived, processed, and remembered. To investigate these interactions, researchers have developed experimental tasks and materials designed to elicit emotional responses in a controlled laboratory setting. Real-life emotional experiences, and our reactions to them, necessarily unfold over time, yet many of these studies have relied on static images. Therefore, little is known about the dynamic effects of emotion on perception and memory of continuous, naturalistic events. Here, we introduce a set of 126 videos of real television news broadcasts that vary in their emotional valence and intensity. In an initial norming study, participants (n = 100) continuously rated the pleasantness of each video during its presentation and judged the overall emotional intensity and valence at the end of each video. In a subsequent memory test, participants reported how vividly they could recall the video details. We found that emotion was related to subjective memory vividness: as in previous studies using static images, memories for emotional videos were reported as more subjectively vivid than memories for neutral videos. We report data on the affective qualities and memorability of each video, as well as the continuous ratings of emotional valence, which will allow researchers to study emotion-related processes while maintaining both ecological validity and experimental control.
