Thepeakcorrelationvs. segmentduration curve tended to approach an asymptotic value at long segment durations (see Figure 2d). For simplicity, we estimated this asymptotic value for each unit by measuring the peak cross-context correlation across lag for the longest segment duration tested (2.48 seconds) (i.e., the rightmost values in the curves shown in Figure 2d).

(b-c)Adaptation indices from different model layers, reflecting the degree to which the unit integration windows are yoked to structurevs. One of the two contexts being compared must be random so that the two contexts differ, but the other context can be random or natural. We repeated all of our analyses using segments centered on either frequent or infrequent words.
