“…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).…”

“…The focus in this approach is on the perception of the structural and dynamic characteristics of real objects taking part in various transformations over time (events); certain structural and dynamic qualities of sound-producing objects would be directly available in the sounds produced, according to the laws of acoustic physics (for discussions of speech and music acoustics, see Fant, 1960;Roederer, 1973). Although this third approach has not been formally applied to research on cerebral asymmetries, it has been used in research and thinking about speech perception (e.g., Summerfield, 1978) and nonspeech auditory perception(e.g., Jenkins, Note 1; Warren, Note 2), as well as visual perception (e.g., Cutting & Koslowski, 1977;Johansson, 1973;Lee, 1980) and even infants' perception of natural events (e.g., Bahrick, Walker, & Neisser, 1981;Dodd, 1979;Ruff, 1980;Spelke, 1979). It would thus seem applicable to further study of the speech vs. music perceptual dichotomy in adults and infants (perhaps to cerebral asymmetries as well-see Fowler,Note 3).…”

Groups of 2-, 3-, and 4-month olds were tested for dichotic ear differences in memory-based phonetic and music timbre discriminations. A right-ear advantage for speech and a left-ear advantage (LEA) for music were found in the 3-and 4-month-olds. However, the 2-month-olds showed only the music LEA, with no reliable evidence of memory-based speech discrimination by either hemisphere. Thus, the responses of all groups to speech contrasts were different from those to music contrasts, but the pattern of the response dichotomy in the youngest group deviated from that found in the older infants. It is suggested that the quality or use of lefthemisphere phonetic memory may change between 2 and 3 months, and that the engagement of right-hemisphere specialized memory for musical timbre may precede that for left-hemisphere phonetic memory. Several directions for future research are suggested to determine whether infant short-term memory asymmetries for speech and music are attributable to acoustic factors, to different modes or strategies in perception, or to structural and dynamic properties of natural sound sources.The existence of a neurobiological dichotomy in human auditory perception, which distinguishes at least some qualities of spoken language from most nonlinguistic auditory events, is strongly implied by the pattern and incidence of functional cerebral asymmetries in adults, particularly as revealed through dichotic ear advantages (e.g.,

“…Dixon and Spitz (1980) have shown that observers simply may not be able to detect onset asynchronies between auditory and visual speech information for temporal differences of less than 190 msec, and these are similar to the values used by Cohen (1984). 1 Moreover, other studies indicatethattemporal asynchronies of 80-400 msec can disrupt the integration of auditory and visual speech information under some circumstances in the McGurk situation (McGrath & Summerfield,1985) and other situations as well (Dodd, 1977(Dodd, , 1979. Thus, it remains unclear from these studies whether, or how much, the McGurk effect is affected by a reduction in the temporal congruence between the auditory and visual signals.…”

Studies of the McGurk effect have shown that when discrepant phonetic information is delivered to the auditory and visual modalities, the information is combined into a new percept not originally presented to either modality. In typical experiments, the auditory and visual speech signals are generated by the same talker. The present experiment examined whether a discrepancy in the gender of the talker between the auditory and visual signals would influence the magnitude of the McGurk effect. A male talker's voice was dubbed onto a videotape containing a female talker's face, and vice versa. The gender-incongruent videotapes were compared with gendercongruent videotapes, in which a male talker's voice was dubbed onto a male face and a female talker's voice was dubbed onto a female face. Even though there was a clear incompatibility in talker characteristics between the auditory and visual signals on the incongruent videotapes, the resulting magnitude of the McGurk effect was not significantly different for the incongruent as opposed to the congruent videotapes. The results indicate that the mechanism for integrating speech information from the auditory and the visual modalities is not disrupted by a gender incompatibility even when it is perceptually apparent. The findings are compatible with the theoretical notion that information about voice characteristics of the talker is extracted and used to normalize the speech signal at an early stage of phonetic processing, prior to the integration of the auditory and the visual information.Over the past four decades, extensive research has been done on the psychological processes underlying the perception and production of spoken language. Much of this research has focused on how the listener processes the acoustic structure of speech in order to arrive at the intended meaning of an utterance.Although speech perception has primarily been considered an auditory process, recent studies have shown that visual information provided by movements of a talker's mouth and face strongly influences what an observer perceives (Green
