“…A number of studies have explored the link between verbal STM capacity and vocabulary development, showing a consistent association between estimates of verbal STM, as measured by nonword repetition tasks, and vocabulary knowledge, especially in younger children (e.g., Avons, Wragg, Cupples, & Lovegrove, 1998;Gathercole, Willis, Baddeley, & Emslie, 1994;Gathercole, Willis, Emslie, & Baddeley, 1992;Service, 1992).
