Behavioral states in response to auditory stimulation in infants prenatally exposed to (experimental group, EG) and unexposed to (control group, CG) auditory stimulation. Figures show the proportions of time spent in quiet sleep (QS), active sleep (AS), and wake (W) states during (4 × 3 min) baseline (silence) and during (4 × 3 min) auditory stimulation conditions in infants who were prenatally exposed to auditory stimulation (A; EG; n = 23) and who were not exposed (B; CG; n = 11). Note that infants familiar to prenatal stimulation (EG; A) fell asleep more likely (less W) as well as slept deeper (more QS) during auditory stimulation and generally exhibited less W states at baseline and stimulation. On the other hand, unexposed infants (CG, B) exhibit a pattern indicating no changes in behavioral states from baseline to stimulation. Curly brackets highlight the significant post-hoc t-test comparisons. * = statistical significance p < 0.05; Error bars refers to ±1 Standard Error of the Mean (SEM).
