Crime films, action films, comedies, or documentaries? A person’s favourite film genre reveals a lot about how their brain works. This is the finding of a new study led by the Martin Luther University Halle-Wittenberg (MLU) that compared data on film preferences with recordings of the brain activity of around 260 people. Fans of action films and comedies reacted very strongly to negative emotional stimuli, while participants who favoured documentaries or crime films and thrillers had a significantly weaker reaction. The results were published in the journal „Frontiers in Behavioral Neuroscience“.
