  2. Novel Task • Microgenesis: shift evolved from new setup • Target: bilateral leg coordination • At 5months: alternating, single kick, simultaneous kick (less stable) • Can baby find it?

  3. Experiment • Conjugate reinforcement • attractive mobile • effective kick -> more move • Yoked or Free condition • Baseline (4min) • Acquisition (10min) • Extinction (2min) • YYF, FYF (yoke group) • FFF, YFF (free group)

  4. Result(1) • Trace of LR legs baseline acquisition

  5. Result (2) • Coordination (r^2) • higher for yoke • “on-line” learning • Back to normal • Coupling function
