Motor learning is described as the ability to perform a motor skill due to practice and/or experience. Research on interventions to enhance limb motor skills can be influenced through the amount, distribution, variability and schedule of practice as well as the type of feedback given, knowledge of performance or knowledge of results. Knowledge of performance provides feedback about how a movement can be refined to successfully achieve the goal movement; knowledge of results provides feedback about the general outcome of a movement e.g. being told ‘nearly there’. In this study, 24 young adults were taught a new language; Hindi. Participants were randomised to one of three conditions: being given knowledge of performance feedback, knowledge of results feedback or a combination of both. Results showed that knowledge of performance feedback and the combined condition of knowledge of performance and knowledge of results feedback resulted in more intelligible, accurate and natural Hindi speech at one day post training, whilst knowledge of performance resulted in highest rated Hindi speech one week post training. This research has implications for future research into interventions for motor speech disorders, such as dysarthria and dyspraxia.
