Figure 2. Integration and segmentation in complex cognition.

(A) Attention to one part of a complex task integrates multiple component fragments (right). As a series of steps is created, the problem is progressively segmented into simpler sub-problems (left). This example is the “travel to Japan” problem from Figure 1B. (B) To create each step, fragments must be selected from many potential candidates and assembled into precisely the correct computational structure.
