Groups of 7 1/2-month-old infants heard 1 of 8 episodes consisting of no, slight, moderate, or large discrepancy between a habituated standard and a transformed auditory stimulus. Patterns of cardiac deceleration supported the hypothesis that attentiveness is an inverted-U function of the degree of discrepancy between stimulus event and schema.…

Infants who were in darkness were presented with objects that made sounds. Objects were within reach and out of reach. Infants reached into the target area more often when the object was in reach than when the object was beyond reach. Infants reached correctly in the dark for objects placed off midline. (BC)

Five studies examined the contributions of syllable-ordering and rhythmic properties of syllable strings to 6- and 9-month-old infants' speech segmentation. Results indicate that the capacity for integrating multiple sources of information in speech perception emerges between 6 and 9 months, in rough synchrony with the emergence of integration in…

Extends dynamic attending theory to developmental questions concerning tempo and time hierarchies. Compares performance of 4- to 10-year-olds, and adults on dynamic attending activities. Suggests that growth trends could be expressed in terms of listeners' engagement of slower attending oscillators with age and musical experience, accompanied by…

Elementary school students demonstrated a developmental trend in ability to judge speed solely on auditory cues. Second graders considered intensity cues relevant, and were most accurate on intensity shifts. Accuracy on frequency shifts increased across grades. Awareness of frequency and frequency-intensity relationships increased with age.…
