A model of adult human memory, OSCAR, is applied to the development of memory for serial order. In the model, development of serial order memory is assumed to result from age-related changes in a dynamic learning-context signal that underpins memory for serial order. Developmental improvement in this dynamic learning-context signal leads to more temporally distinctive representations in memory, and this leads in turn to a reduction in order errors. It is shown that the model correctly predicts developmental changes in the movement error gradients in children's serially ordered recall, as well as developmental changes in the number of movement errors obtained. The model is also applied to repetition errors across development.
