Actors May Suppress Their "Core" Sense of Self To Perform New Roles

Actors may suppress their core sense of self when acting, as they immerse themselves in a new role, finds a new study by UCL researchers.
The research, published in Journal of Cognitive Neuroscience, suggests that when actors take on a new character, they may be able to suppress their everyday self – implying that theatre training may have a big impact on the fundamental mechanisms of the human brain.
Researchers worked in collaboration with Flute Theatre, who create and deliver interactive productions of Shakespeare for autistic individuals and their families, using a series of sensory drama games, known as the Hunter Heartbeat Method.
The team used wearable brain imaging technologies pioneered at UCL’s department of Biomedical Engineering, alongside physiological measurement devices, to evaluate the brain activity of actors as they rehearsed scenes from Shakespeare’s A Midsummer Night’s Dream.
The findings showed that when the actors heard their own name during the performance, their response was suppressed in the left anterior prefrontal cortex of the brain, which is usually associated with self-awareness. The same result was witnessed consistently in six actors who were tested when rehearsing several times over a week.
Meanwhile, when the performers were not in acting conditions, they responded normally to hearing their own name.
Lead author, PhD candidate Dwaynica Greaves said: “We used new brain imaging methods to see into the brains of professional actors as they rehearsed Shakespeare, to try and understand the neuroscience of complex dynamic social interactions.
“The shout of a person’s own name is a powerful and compelling sound which normally makes the subject turn their head. It also engages the prefrontal cortex of the brain. However, our findings suggest that actors may learn to suppress their sense of self as they train in the theatre and take on a different character.
“This is the first time that neuroscientists have been able to record brain activity in actors as they perform a role. We hope that this study will help us understand what theatre training does to the brain and to build new connections between neuroscientists and theatre professionals.”
As part of the study, the researchers also investigated the interpersonal coordination between pairs of actors rehearsing together, to see how they synchronise their bodies, heart rates and brains.
They found that during rehearsals there were similar activity patterns in the right inferior frontal gyrus and the right frontopolar cortex of the brains of two actors who were working together. These areas are associated with social interaction and action planning. The effects were specific to the brain data and were not seen in the heartbeat or breathing data, showing that there are specific brain systems that are coordinated during complex social interactions.
Dwaynica Greaves said: “Our findings indicate that collaborating with the theatre industry could be helpful in producing theories about social interaction that could also be investigated in the real world.
“Our lab will continue to investigate the effects of theatrical training on an actor’s sense of self, in the hope that theatrical training could aid the development of important social cognitive abilities.
“Our future work will look at whether young people, including those with autism, can learn new social skills by taking part in theatre activities.”
Artistic Director of Flute Theatre, Kelly Hunter, said: “‘What’s in a name?’ cries Juliet. More than meets the eye, it would appear.
“As ever, Shakespeare would seem to have understood instinctively 400 years ago, what scientists are proving empirically now.
“I had always been interested in the changes that occur internally when we hear, speak and even think about our own name as well as the names of those we have strong feelings toward.
“The scientific recognition that our physiological selves respond when we hear our names, deepened my understanding of the sensory drama games I play with autistic individuals, especially those who are non-verbal.
“Since the collaboration with UCL in 2019, I have deepened and developed the way I use the names of the autistic participants within the framework of our performances. It’s been a perfect blend of artistic instincts and scientific questioning creating a deeper pool of understanding of how we communicate.”
In the future, the team hope to also investigate the difference between trained and untrained actors.
