Responsiveness of current breeders with dependent infants (DI) versus independent infants (II) during (a, c) own infant vocalization tests (OV) and versus noncurrent breeders (NI) during (b, d) unfamiliar infant vocalization tests (UV). (a, b) Frequency of investigatory behaviour. (c, d) Time spent near stimulus. Means are shown with SE (box) and SD (vertical lines). Lines spanning different histograms indicate categories of breeders between which differences were significant at P <0.05.
