Figure 7.

Performance on recognition of trained (blue) versus untrained shapes that either shared (red) or did not share (yellow) a component with the trained shape, for four-line shapes. For the purposes of this illustration, the shared components are highlighted in red. There was significant improvement in recognizing untrained shapes that shared a component with the trained shape but not for shapes without shared components. Here, training and transfer for four-line shapes followed the same pattern as for three-line shapes. Single subject, Error bars represent SEs across individual blocks. *p < 0.01; **p < 0.001, compared with the pretraining levels of performance.
