Procedural memory underpins the learning of skills and habits. It is often tested in children
and adults with sequence learning on the serial reaction time (SRT) task, which involves
manual motor control. However, due to infants' slowly developing control of motor actions,
most procedures that require motor control cannot be examined in infancy. Here, we
investigated procedural memory using an SRT task adapted for infants. During the task,
images appeared at one of three locations on a screen, with the location order following a …
