Applied behaviour analysis postgraduate personal statement example

Personal statement example

My interest in applied behaviour analysis began with a second-year module on learning theory, where I was struck by how much explanatory work simple principles could do. Reinforcement, stimulus control and extinction were not abstractions but descriptions of things I recognised from the after-school club where I worked on Thursdays. For my final-year project I designed a small study on token reinforcement and task persistence, giving undergraduate volunteers either continuous or intermittent points for completing a tedious sorting task. My sample was modest and the effect I found was not large, but the process taught me more than the result: how much care operational definitions require, how easily a procedure drifts when two people run it, and why inter-observer agreement matters before any claim is made about change. I read Cooper, Heron and Heward alongside my supervisor's suggestions, and returned to it repeatedly when writing up.

Wanting to see behaviour analysis outside a laboratory, I arranged a two-week work-shadowing placement with a behaviour support team in a special school. My role was strictly observational: I sat at the side of classrooms, was shown how partial interval recording sheets were completed, and practised scoring alongside a member of staff so we could compare our tallies. I was not responsible for any pupil's programme and did not deliver teaching, but watching a functional behaviour assessment take shape over several days changed how I think. What impressed me was the patience of it. Staff spent a long while gathering information and speaking to parents and teaching assistants before proposing anything, and the eventual plan was built around teaching a more efficient way to ask for a break rather than simply reducing an unwanted behaviour. I also saw how much of the work is social: explaining a procedure clearly enough that a busy classroom team can run it consistently is as much a skill as designing it.

Since graduating I have worked part-time supporting a teaching assistant at an after-school club for primary-aged children, including two children with additional needs. My responsibilities are ordinary ones, setting up activities, supervising snack time and helping with transitions, but they have given me a realistic sense of how environments shape behaviour. When one child struggled with the move from free play to tidying up, the staff team agreed to give a consistent two-minute warning and a visual countdown. I was not the author of that idea, but I helped deliver it reliably and noticed how much difference consistency made compared with our earlier, well-meant improvisation. Volunteering at a summer play scheme has similarly taught me to work with whoever is in the room rather than an imagined ideal group.

I am applying for postgraduate study because I want the theoretical depth and supervised practice that a master's provides, particularly in single-case experimental design, functional assessment and ethical decision-making. I am conscious that behaviour analysis has been criticised, including by autistic adults, for prioritising compliance and appearance over the person's own goals, and I want to study that debate seriously rather than defensively. Questions about assent, socially significant outcomes and who decides what counts as improvement seem to me central to doing the work well. My longer-term aim is to qualify and practise in education settings, and eventually to support staff teams rather than only working directly with individuals.

Alongside my degree I sang in a university choir and now sing locally, which has quietly reinforced the value of turning up regularly and listening carefully to other people. I am organised, comfortable with data, and willing to be corrected, which I think matters more in this field than confidence. I would welcome the chance to build on my undergraduate foundation under close supervision.
