Move on up: Fingertip forces and felt heaviness are modulated by the goal of the lift.

As the p value for this main effect approached significance, we followed this test up with the same post hoc analyses as for the forces (see Fig. 5a ), finding that a significantly higher rate of grip force was used to move the object to the higher level than to the same level ( p = .023, Cohen’s d = 0.51), but not to the lower level ( p > .99).
