Fig 1.
Trial procedure for spatial working memory task.
Participants were asked to remember and then recall the order and locations of red blocks. Symmetry judgements were made between each block presentation.
Fig 2.
Example stimuli used for the mental rotation task.
Participants were asked to compare the orientation of a stimulus image to either a second image (block condition) or vertical orientation (hand condition). Orientations varied across trials (0°, 50°, 100°, 150°). Stimulus images for the block condition were from Ganis and Kievit (2015).
Fig 3.
Example trial from the Tower of London task.
Participants had to plan and execute the steps required to get the marble positions from the start state to those of the goal state.

Accumulated dance experience by age.
Accumulated hip hop and other dance style experience (cube-root of total accumulated hours) as a function of number of years dancing each type of dance (binned by three-year increments). Each colored line segment indicates the accumulated experience of a specific participant.

A linear mixed model was used to compute a mixed-factor ANOVA.

Relation between mental rotation task performance and hip hop dance experience.
Scatter plot of mental rotation task reaction time (RT) and total hip hop hours across condition (block, hand) and orientation (0°, 5°, 100°, 150°). Across participants, as hip hop experience increased, RTs decreased for the 150° hand condition relative to the 0° hand condition. Shaded areas indicate the 95% CI for the regression line.
