“…For example, 4-month-old infants matched auditory and visual stimulation from complex, moving objects on the basis of tempo (Spelke, 1979). However, other studies of intersensory matching have yielded mixed results, with some failing to find evidence of intersensory perception of sounds matching the tempo of isochronous moving objects (Lewkowicz, 1992(Lewkowicz, , 1994 or isochronous flashing lights (Humphrey & Tees, 1980;Lewkowicz, 1985b), at least prior to 6 to 10 months of age (see Lewkowicz, 2000, for a review). Given the differences in stimulus modality, complexity, and procedures, it is difficult to compare and draw firm conclusions from results across studies.…”

L. Bahrick and R. Lickliter (2000) proposed an intersensory redundancy hypothesis that states that information presented redundantly and in temporal synchrony across two or more sensory modalities selectively recruits infant attention and facilitates perceptual learning more effectively than does the same information presented unimodally. In support of this view, they found that 5-month-old infants were able to differentiate between two complex rhythms when they were presented bimodally, but not unimodally. The present study extended our test of the intersensory redundancy hypothesis to younger infants and to a different amodal property. Three-month-olds' sensitivity to the amodal property of tempo was investigated. Results replicated and extended those of Bahrick and Lickliter, demonstrating that infants could discriminate a change in tempo following bimodal, but not unimodal, habituation. It appears that when infants are first learning to differentiate an amodal stimulus property, discrimination is facilitated by intersensory redundancy and attenuated under conditions of unimodal stimulation.

“…Four-month-olds looked longer at the films whose tempo matched the tempo of the sounds, suggesting that they discerned the different tempos. Other researchers have failed to observe this type of 'auditory-visual matching' on the basis of tempo before 6 months, although they generally observed that infants' visual explorations are affected by the tempo of stimulation (Humphrey & Tees, 1980;Lewkowicz, 19856, 1988u,b, 1992Moore & Gibbons, 1988). These studies utilized spatially static or computer-animated stimuli in contrast to Spelke's (1979) presentation of dynamic live-action films of actual objects striking a surface.…”

A habituation procedure was used to examine 7-month-old infants' discrimination of changes in the rhythm (Expt 1) or the tempo (Expt 2) of an auditory-visual event. Events consisted of videos of a hammer striking a surface displaying a characteristic rhythm and tempo along with the synchronized impact sounds. In Expt 1 , 3 2 infants were habituated to one rhythm presented at a constant tempo followed by test trials of a novel rhythm presented at the familiar tempo. Across subjects, four different stimulus rhythms were presented at each of four different constant tempos. Infants demonstrated significant visual recovery to a novel rhythm at all stimulus tempos. In Expt 2, 32 infants were habituated to events displaying one rhythm and tempo followed by test trials presenting a novel tempo and the familiar rhythm. Infants showed a significant visual recovery to a novel tempo, which was apparent across four different underlying rhythm contexts. More robust discrimination was observed for more extreme tempo contrasts. These data suggest that 7-month-old infants are sensitive to the invariant rhythm and tempo of bimodal events.

“…This study along with others have shown that there are developmental changes in detection of audiovisual synchrony (Bahrick, 1987;Humphrey & Tees 1980). Spelke, Born & Chu (1983) found that 4-month-old infants perceived correspondences between an object and a sound when there was a pause and change in trajectory of an object, regardless of whether the change coincided with an impact against a surface.…”

“…Furthermore, Humphrey and Tees (1980) provide some evidence for the detection of tempo in older infants. Menten and Cohen (1979) have replicated the findings of Spelke (1979) were presented out of phase by one half of a second and four were out of phase by one second.…”

“…They can detect common tempo and the synchrony of soundbursts with the visible impacts of objects. Humphrey and Tees (1980) also examined infants' perception of audio-visual tempo and synchrony using two visual displays of fast versus slow flashing lights side by side and with tones which were temporally synchronized to one of the displays. The visual display and corresponding tones differed in temporal rate by a factor of four.…”

Infants' detection of synchrony between sounds and pauses in the movement of an object

Alberga, Linda, "Infants' detection of synchrony between sounds and pauses in the movement of an object" (1994 The present study investigated the development of sensitivity to temporal synchrony between sounds of impact and pauses in the movement of an object by infants of 2 1/2, 4 and 6 months of age. Ninety infants were tested across four experiments with side-by-side videos of a red and white square and a blue and yellow triangle along with a centralized soundtrack which was synchronized with only one of the films. This preference phase was then followed by a search phase, where the two films were accompanied by intermittent bursts of the soundtrack from each object. Twomonth-olds showed no evidence of matching films and soundtracks on the basis of synchrony, however 4-month-olds looked more on the second block of trials to the object which paused when the sound occurred and directed more first looks during the preference phase to the matching object.Six-month-olds demonstrated significantly more first looks to the mismatched object during the search phase only. These iii results suggest that infants relate impact sounds with synchronous pauses in continuous motion by the age of four months.
