Scores for conditional comparisons.

Mean scores with standard error (SE) and exact p-values for 2-tailed paired bootstrap tests (significant p-values in bold face type) are shown for phonological and sequence comparisons between conditions generated at 75d (n = 11, left columns) and 65d (n = 10, right columns). Results are first reported for motif-, clip-, and string-based analyses, followed by syllable scores. For the latter, the investigator selected 25 consecutive renditions of the same syllable, computed an average of ∼3 syllables per bird and obtained the mean from 10 birds at 65d and 11 birds at 75d.
