“…Within the context of early speech perception and language development, 2-month-olds are able to perceive the amodal property of temporal and spatial synchrony uniting Intersensory Perception 11 lip movements and the onset/offset of auditory speech (e.g., Dodd, 1979). By 4-months of age, infants match visual speech with the appropriate auditory information (i.e., different vowel sound with the appropriate facial expression; Kuhl & Meltzoff, 1982;Patterson & Werker, 1999;Werker, 2003). Related research further demonstrates that slightly younger infants (i.e., 3-montholds compared to 4-month-olds) not only match visible and auditory speech sounds, but also use multisensory auditory-visual speech in imitating the speech of a live actress (Legerstee, 1990).…”

“…Baby's van vier maanden oud, die tegelijkertijd twee video's te zien krijgen van een spreker die een klinker uitspreekt, zijn in staat om het goede gezicht aan een auditief aangeboden klinker te koppelen (Kuhl & Meltzoff, 1982;Patterson & Werker, 1999) en zelfs baby's van twee maanden oud kunnen de correspondentie tussen auditieve en visuele spraak detecteren (Patterson & Werker, 2003). Het is echter ook bekend dat de impact die liplees-informatie heeft op de auditieve spraak verwerking groter wordt naarmate baby's opgroeien (Massaro, 1984;McGurk & MacDonald, 1976).…”

“…Multimodal aspects of vocalizations that cooccur with mouthing may contribute to the development of consonant information. Infants demonstrate cross-modal sensitivity to adults' vowel vocalizations at 4.5 months, looking longer to films of talkers articulating vowels that matched auditorily presented stimuli than to films that did not (Kuhl & Meltzoff, 1982, 1984Patterson & Werker, 1999). At around the same age, infants also begin to imitate vowels they hear (Kuhl & Meltzoff, 1996).…”

Although vocalization and mouthing are behaviors frequently performed by infants, little is known about the characteristics of vocalizations that occur with objects, hands, or fingers in infants' mouths. The purpose of this research was to investigate characteristics of vocalizations associated with mouthing in 6-to 9-month-old infants during play with a primary caregiver. Results suggest that mouthing may influence the phonetic characteristics of vocalizations by introducing vocal tract closure and variation in consonant production.Mouthing, defined as contact of an object with the mouth, lips, or tongue (Rochat, 1989;Ruff, Saltarelli, Capozzoli, & Dubiner, 1992), is a common behavior during infancy (Belsky & Most, 1981;Fenson, Kagan, Kearsley, & Zelazo, 1976;Kopp, 1976). In a study of 7.5− to 21-month-old infants (Belsky & Most, 1981), all 40 infants displayed mouthing behavior during play with toys between 7.5 and 13.5 months. In addition to its prominence across infants, mouthing is a regularly occurring behavior both in terms of number of occurrences and duration of episodes (Kopp, 1976;Ruff, 1984;Whyte, McDonald, Baillargeon, & Newell, 1994).Studies of mouthing have not typically examined vocalizations associated with episodes of mouthing. Moreover, studies of mouthing often focus on the mouthing of objects, less frequently investigating contact of the hands and fingers with infants' mouths. Elbers (1982), however, noted that between ages 6 and 12 months her son vocalized with the back of one hand against his mouth and while holding his fingers in his mouth. She interpreted both activities as variants in bringing about vocal tract closure and constriction. In an additional study of 4 infants between 6 and 11 months, Ejiri and Masataka (2001) documented both the frequent occurrence of mouthing and co-occurrences of mouthing and vocalization; however, they did not describe the characteristics of co-occurring vocalizations. Descriptions of vocalizations that co-occur with mouthing may be important for three reasons: Mouthing is an exploratory behavior that may extend to encompass exploration of co-occurring vocalizations; the peak period of mouthing behavior in infancy coincides with and may contribute to advances in consonant production; and mouthing, which appears to contribute to the development of multimodal object perception, may also contribute to the development of multimodal speech perception. Mouthing and ExplorationStudies documenting the exploratory nature of object-related mouthing have consistently shown that infants use mouthing as a means to explore object characteristics and discover what they afford for action (Fenson et al., 1976;Rochat, 1989;Ruff et al., 1992). Moreover, infants vary their approach to exploration to maximize the information they obtain (e.g., scratching objects to obtain information about their affordance for noise; Rochat, 1989) and exploit affordances differentially (e.g., fingering textured objects and mouthing patterned objects). The exploratory nature of mouth...
