S1. Play gesture ethogram; S2. Differences in magnitude of D between the i-th and the (i-1)-th gesture type with the smallest total duration, D; S3. The effect of sorting by f, d or D; S4. Mean duration and frequency of use (for each age class) of play gesture types. S.D. denotes standard deviation; S5A: R Code for the calculation and significance testing of L; S5B: R Code for the calculation and significance testing of M; S6. Results of analyses of subsets of play gestures, ordered from low to high values of D, and from high to low values of D. Significant results are highlighted in grey. Values for L are indicated in seconds.; S7. Results of analyses of subsets of play gestures, ordered from low to high values of f, and from high to low values of f. Significant results are highlighted in grey. Values for L are indicated in seconds.; S8. Results of analyses of subsets of play gestures, ordered from low to high values of d, and from high to low values of d. Significant results are highlighted in grey. Values for L are indicated in seconds.
