ICMPC14: Dyadic improvisation and mirroring of finger movements

As I unfortunately (or, as the reason is a newborn baby in the family, fortunately) were not able to attend the ICMPC14, I decided to summarise our study (co-authored with Maija Niinisalo and Riitta Hari, a poster was supposed to appear at the Music & Movement 3 session on Thursday, 4:00 pm, Seacliff A-C, Th23) on dyadic improvisation in this blog post. The blog post format allows me to use videos etc. to illustrate the tasks and the data better than a static poster would, and also lets me write a bit more about it than would fit in a poster. If you have any questions, drop me an email. We are currently writing this up as a journal article, so you’ll get the whole story soon, I hope.

Dyadic improvisation and mirroring of finger movements


We studied kinematics and coordination in a mirror game using fluent, improvised movements (circle drawing & free movement). 32 participants took part in dyads. In turn, one of the participants was appointed the leader, or the dyad was instructed to share leadership. Hand movements were recorded with optical motion capture.

Compared to the leader–follower condition, sharing leadership resulted in more synchronous circles, smoother free movements, and stronger mutual adaptation.
