Death Angel were recently used in a psychological study that shows liked and disliked music are equally disruptive to serial recall. The disliked music in the study was the song "Thrashers" by Death Angel.

Dr. Nick Perham explained his reasoning by using Death Angel as the "disliked" music in the study: "We needed a track that most participants would say they did not like. Having been a fan of metal music since my teens, I was pretty confident that a thrash metal song would do the trick as most people never seemed to like the music I liked. In choosing a thrash metal song, I needed a song that was heavy but also allowed the listener to hear many of the different components of the song - the acoustical variation between the successive sound items. We chose "Thrashers". Participants were only allowed to participate in the study if they disliked thrash metal as a musical genre...

Personally, I have been a fan of Death Angel since The Ultra-Violence and saw them at the Bristol Bierkeller around 1990 supporting the Act III album."

For decades research has shown that listening to music can alleviate anxiety and depression, enhance mood, as well as increase cognitive functioning such as spatial awareness. However, until now, research has not addressed how we listen to music. For instance, is the cognitive benefit still the same if we listen to music whilst performing a task, rather than before it? Further, how does our preference for a particular type of music affect performance? A new study from Applied Cognitive Psychology shows that listening to music that one likes whilst performing a serial recall task does not help performance any more than listening to music one does not enjoy.

The researchers explored the "irrelevant sound effect" by requiring participants to perform serial recall (recall a list of 8 consonants in presentation order) in the presence of five sound environments - quiet, liked music (e.g., Rihanna, Lady Gaga, Stranglers and Arcade Fire), disliked music (the track "Thrashers" by Death Angel), changing-state (a sequence of random digits such as '4, 7, 1, 6') and steady-state ('3, 3, 3'). Recall ability was approximately the same, and poorest, for the music and changing-state conditions and the most accurate recall occurred when participants performed the task in the quieter steady-state environments.

Lead researcher Nick Perham explains: "The poorer performance of the music and changing-state sounds are due to them containing lots of acoustical variation the order of which impairs the ability to recall the order of items, via rehearsal, within the presented list. Other tasks and processes that also require the ability to retain order information in the short-term via rehearsal, such as mental arithmetic, may be similarly affected by their performance in the presence of changing-state, background environments."

Although music can have a very positive effect on our general mental health, music can, in the circumstances described, also have negative effects on cognitive performance. Perham remarks: "Most people listen to music at the same time as, rather than prior to, performing a task but to reduce the negative effects of background music when recalling information in order, one should either perform the task in quiet or only listen to music prior to performing the task."
