Instructor: Mafuyu Kitahara
Material: Thelen, E. (1995) “Time-scale dynamics and the development of an embodied cognition” in R. Port and T. van Gelder (eds.) Mind as motion, Cambridge: MIT Press
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?
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)
Result(1)Trace of LR legs
baseline
acquisition
Result (2)
Coordination (r^2)higher for yoke
“on-line” learningBack to normal
Coupling function
