Snapshots of the feeding action; bringing food to the recipients hand/mouth.
(A). Snapshots of the recipient leaning forward to eat off the back of her hand (B) in the irrational and constrained condition (upper) and the rational and constrained condition (lower).
Figure 2.
Measured from baseline to test block, separate for the rational and irrational conditions of the unconstrained and constrained contexts. Error bars represent SE and the horizontal line represent conditions that significantly differ from each other.
