Scroobius Pip is a patron of stamma.org and has had a stammer himself since the age of 4.
I photographed Pip and a number of other people who stammer for a national awareness campaign shown on billboards around the country .
About 8% of children will stammer at some point, but most will go on to talk fluently. For up to 3% of adults it will be a lifelong condition. Stammering affects mainly men and every ethnicity.
There is no link between stammering and intellectual capacity. Like other neurological conditions, it covers a spectrum, everyone stammers differently and to different degrees. For some there’ll be periods of their life when they stammer less and others when they will struggle to speak. Many find that as they get older the condition improves.
The physical act of stammering can be a tiny part of the experience. The bigger part is often the mental machinations that someone who stammers endures. Anticipating times when they'll need to talk, the negative responses, the ever-present expectation that they need fixing or just need to breathe properly. Feelings of shame, embarrassment, anger, anxiety and fear. Frustration that saying one’s name – the one thing that most people who stammer will find hard to say – will stymie their every encounter. The frustration of not being taken seriously.
