Appendix

For each experiment, a pre-test was conducted in order to i) control for the temporal homogeneity of the action sequences, and ii) to select three temporal windows relevant for the subsequent experiments (i.e. Inf1, Inf2, Inf3 or low, moderate, high amount). All movies were filmed using a digital camera (Sony®- HDR-SR7) and were acquired and tailored using the software Adobe Premiere®.
