“…These results are consonant with previous findings that newborns did not show a preference for their own fathers' voices over other unfamiliar male voices in spite of their ability to discriminate them (DeCasper & Prescott, 1984). In contrast to these data with fathers' voices, infants prefer to listen to the maternal voice even when heard in a variety of different contexts (Cooper et al, 1997;DeCasper & Fifer, 1980;Fifer, 1987;Mehler, Bertoncini, Barriere, & JassikGerschenfeld, 1978;Mills & Melhuish, 1974;Moon & Fifer, 1990;Standley & Madsen, 1990). Therefore, it was surprising that 4-month-olds did not attend more to their fathers' voices over other male voices, especially when the fathers' voices were extracted from the context of normal father -infant interactions (i.e., ID speech).…”

“…Newborn infants may recognize their mothers' faces, even when extraneous cues (e.g., olfactory and/or movement) and contrast cues (e.g., hair and complexion) are controlled (Bushnell, Sai, & Mullin, 1989;Field, 1985;Sherrod, 1979;Walton, Bower, & Bower, 1992). Similarly, preference for the maternal voice appears early in development (DeCasper & Fifer, 1980;Fifer, 1987;Hepper, Scott, & Shahidullah, 1993;Mills & Melhuish, 1974;Moon & Fifer, 1990;Ockleford, Vince, Layton, & Reader, 1988;Standley & Madsen, 1990).…”

“…This is in contrast to the maternal voice studies where recognition is intact as early as 24 hr after birth . It has been suggested that the early developing maternal recognition system could be due to extended prenatal experience (DeCasper & Spence, 1986;Lecanuet, Granier-Deferre, & Busnel, 1991;Moon & Fifer, 1990;Panneton, 1985;Spence & DeCasper, 1987). For instance, we know that audition occurs prenatally by the 20th week of gestation Querleu, Renard, Versyp, Paris-Delrue, & Crepin, 1988;Querleu, Renard, Boutteville, & Crepin, 1989).…”

“…Although these skills are acquired at different times during development (Jusczyk, 1993), it appears that newborn infants already possess remarkable discriminatory capabilities: Two-day-old infants can discriminate between stop consonant contrasts (e.g., ba vs. da) and between following vowel contrasts (e.g., ba vs. bi; Bertoncini, Bijeljac-Babic, Blumstein, & Mehler, 1987), and by 4 days postnatal age, infants can encode sufficiently detailed information to detect the addition of a new syllable to a set of familiar ones (Jusczyk, Bertoncini, BijeljacBabic, Kennedy, & Mehler, 1990). In fact, there are data that suggest that prenatal auditory experience may have an important influence on early speech perception: Three- -Accepted by previous editor, Myron L.

The purpose of this study was to determine whether temporal pattern and/or spectral complexity were important stimulus parameters for eliciting a cardiac orienting reflex (OR) in low-risk human fetuses. Each of28 term fetuses was exposed to four sounds formed from the four different combinations of temporal pattern (pulsed, continuous) and spectral complexity (sine wave, /3/). The fetal cardiac electrical signal was captured transabdominally at a rate of 1024Hz, and fetal R-waves were extracted by using adaptive signal-processing techniques. We found that pulsed sounds elicited a significantly greater decrease in heart rate (HR) than did continuous sounds. However, the HR response was relatively unaffected by spectral complexity. For the pure tone and the phoneme used in this study, our results indicate that temporal characteristics were more effective at eliciting a cardiac OR in human fetuses than was spectral complexity.Successful word recognition involves the perception and discrimination of different sounds, recall of a cognitive representation of specific sounds, and segmentation of speech into the correct sequence of words (Jusczyk, 1993). Although these skills are acquired at different times during development (Jusczyk, 1993), it appears that newborn infants already possess remarkable discriminatory capabilities: Two-day-old infants can discriminate between stop consonant contrasts (e.g., ba vs. da) and between following vowel contrasts (e.g., ba vs. bi; Bertoncini, Bijeljac-Babic, Blumstein, & Mehler, 1987), and by 4 days postnatal age, infants can encode sufficiently detailed information to detect the addition of a new syllable to a set of familiar ones

“…Thus, sensitivity to rhythmic patterning is in place very early. So indeed is sensitivity to other aspects of prosodic structure [infants prefer pauses to be placed between rather than within prosodic phrases (54), for instance], as well as discriminatory preference of licit (e.g., tap) over illicit (tfp) sequences of consonants and vowels (55,56). It is thus not unreasonable to propose that the infant notes many systematic properties of speech input before being able to settle on candidate phonemic contrasts and other phonological structures.…”

Early phonology revealed by international adoptees' birth language retention

Until at least 6 mo of age, infants show good discrimination for familiar phonetic contrasts (i.e., those heard in the environmental language) and contrasts that are unfamiliar. Adult-like discrimination (significantly worse for nonnative than for native contrasts) appears only later, by 9-10 mo. This has been interpreted as indicating that infants have no knowledge of phonology until vocabulary development begins, after 6 mo of age. Recently, however, word recognition has been observed before age 6 mo, apparently decoupling the vocabulary and phonology acquisition processes. Here we show that phonological acquisition is also in progress before 6 mo of age. The evidence comes from retention of birth-language knowledge in international adoptees. In the largest ever such study, we recruited 29 adult Dutch speakers who had been adopted from Korea when young and had no conscious knowledge of Korean language at all. Half were adopted at age 3-5 mo (before nativespecific discrimination develops) and half at 17 mo or older (after word learning has begun). In a short intensive training program, we observe that adoptees (compared with 29 matched controls) more rapidly learn tripartite Korean consonant distinctions without counterparts in their later-acquired Dutch, suggesting that the adoptees retained phonological knowledge about the Korean distinction. The advantage is equivalent for the younger-adopted and the olderadopted groups, and both groups not only acquire the tripartite distinction for the trained consonants but also generalize it to untrained consonants. Although infants younger than 6 mo can still discriminate unfamiliar phonetic distinctions, this finding indicates that native-language phonological knowledge is nonetheless being acquired at that age.language acquisition | adoption | phonology | language memory T o talk to others, and to understand what others say, we need to know the phonological structure of the language we are using. Phonology embraces, for instance, the single-sound contrasts that distinguish one word from another, or the sequence constraints that apply to sounds; so if we are speaking English, we need to distinguish rye from lie, and if we hear [m] followed immediately by [b], we know that they belong to different syllables, as in somebody. Neither assumption holds for all languages. Phonological knowledge is highly language-specific.It is also abstract: not so much knowledge of the sounds and words in the language, but knowledge about those sounds and words, and the rules that govern them. Such knowledge is constantly called into play in adult talking and listening. When talkers must repeat others' utterances, they repeat the sounds that are said, but do so by using their own accent, not by imitating the accent in which the sounds are said (1). If talkers are exposed to novel phoneme sequence constraints in perception, they quickly apply them in production (2). In slips of the tongue, transposed elements accommodate to the new rather than to the originally intended phonetic context, su...
