Straight-Pulley Condition

(A) Locations of the hands (red circles) and four pulleys used in the straight-pulley condition.

(B) Each blue cross represents the median force vector generated by a given participant during catch trials after learning. The thick blue lines show mean force vectors, averaged across participants, and the blue ellipses represent the corresponding 50% confidence ellipses. Each green cross represents the median force vector during transfer trials after learning in the training position. The thick green line shows the mean force vector, averaged across participants, and the green ellipse represents the corresponding 50% confidence ellipse.

(C) Each red cross represents the median transfer angle for a single participant, and the thick red line shows mean angles averaged across participants. The shaded areas represent ± 1 SE. Object-centered and arm-centered predictions are represented by dashed and dotted lines, respectively.
