This article explores children’s rule-following behaviour, as part of an ongoing study underway in the Contextual Behavioural Science lab at University College Dublin. It builds a critical case regarding the most suitable methodologies to approach this topic, emphasising the need to meaningfully capture children’s voices and views regarding their own rule-following behaviours, with particular reference to the suitability of qualitative research methods. This will contribute to/inform research in the field and improve the level of understanding that is currently available of children’s rule-following behaviour.
