“…These regions are associated with reward, fear, pain, motor, and somatosensory processing consistent with previous work characterizing positive valence in naturalistic films (80). State 2 was associated with increased activity in the vmPFC, PCC, dmPFC, TPJ, and superior temporal sulcus consistent with naturalistic work investigating negative affective experiences (81). These regions comprise the default mode and are associated with social processing.…”

How we process ongoing experiences is shaped by our personal history, current needs, and future goals. Consequently, ventromedial prefrontal cortex (vmPFC) activity involved in processing these subjective appraisals appears to be highly idiosyncratic across individuals. To elucidate the role of the vmPFC in processing our ongoing experiences, we developed a computational framework and analysis pipeline to characterize the spatiotemporal dynamics of individual vmPFC responses as participants viewed a 45-minute television drama. Through a combination of functional magnetic resonance imaging, facial expression tracking, and self-reported emotional experiences across four studies, our data suggest that the vmPFC slowly transitions through a series of discretized states that broadly map onto affective experiences. Although these transitions typically occur at idiosyncratic times across people, participants exhibited a marked increase in state alignment during high affectively valenced events in the show. Our work suggests that the vmPFC ascribes affective meaning to our ongoing experiences.

“…Researchers examining social and emotional information processing are increasingly utilizing video stimuli, as opposed to written stimuli, precisely because videos are more ecologically valid, engaging and emotionally triggering to viewers, especially videos of an aversive, stress-inducing quality (Coccaro et al, 2021; Nanni et al, 2018). Furthermore, motion in facial expressions provides more emotional information to viewers, thus activating more emotion-specific brain regions (Trautmann et al, 2009), while the emotional information in audio recordings likely adds another layer of affective activation, increasing the risk for secondary trauma when the voice content involves the traumatic experiences of others (Etherington, 2007; Kiyimba & O’Reilly, 2016).…”

High-quality video and audio recordings of violent crimes, captured using now ubiquitous digital technologies, play an increasingly important role in the administration of justice. However, the effects of exposure to gruesome material presented in this form on criminal justice professionals who analyze, evaluate, and use this potentially traumatic content in the context of their work, are largely unknown. Using long interviews and constructivist grounded theory, this qualitative study sought to explore experiences of exposure to video evidence of violent crime among Canadian criminal justice professionals. Sixteen individuals including police, lawyers, judges, psychiatrists, law clerks, and court reporters volunteered to participate in qualitative long interviews asking about workplace exposures to violent videos. Themes identified address the ubiquity of video evidence of violent crime; proximity to violence through video; being blindsided through lack of preparedness for violent content; repeated exposures through multiple and protracted viewings; insufficient customary methods for self-protection; and the enduring impact of exposure to videoed violence. We determine that criminal justice professionals are increasingly and repeatedly presented with deeply disturbing imagery that was once imperceptible or unknowable and thus previously held at a greater distance. Elements of what is newly visible and audible in video evidence of violent crime create a new emotional proximity to violence that potentially increases the risks of secondary trauma and underscores the need for improved safety measures.
