Infant-directed speech in African-American mothers
… the presence of prosodic modifications in the infant-directed speech of African American mothers; (2) examine the differences in the acoustic properties of the infant- and adult-directed speech of European American and African American mothers; (3) examine the relationship between the acoustic …

The Ability of Speaking Rate to Influence Infants' Preferences for Infant-Directed Speech
… how rate affects visual preferences in human infants and auditory preferences in avian infants. In the visual domain, it seems that human infants prefer stimuli (e.g., flashing displays) presented at faster relative rates. Research using avian species has shown that ducklings, for example, …

Discrimination of Linguistic and Prosodic Information In Infant-Directed Speech by Six-Month-Olds
… paralinguistic from the linguistic aspects of infants' perception of infant-directed (ID) speech. Several studies have shown that infants beginning at a few days after birth discriminate native from nonnative speech and can discriminate specific contours (rising, falling, rising-falling) in ID …

Taking the 'Mother' out of 'Motherese': young infants' preference for mothers' use of infant-directed speech
Previous research on infant perception of speech has shown that infants prefer their mother's voice over the voice of an unfamiliar female. Additionally, infants show a preference for the type of speech that is normally directed towards infants, known as infant-directed (10) speech. The linguistic …

Social and Nonsocial Priming Effects on 12- to 15-Month-Olds’ Preferences for Infant-Directed Speech
… and thus shortens response time in adults. In infant research, various visual and auditory/visual events are used as attention getters to orient the infant to a screen and alert them to upcoming information for their detection, discrimination, and/or recognition. However, the influence of …

The Perceptual Draw of Prosody: Infant-Directed Speech within the Context of Declining Nonnative Speech Perception
Infant speech perception develops within the context of specific language experience. While there is a corpus of empirical evidence concerning infants' perception of linguistic and prosodic information in speech, few studies have explored the interaction of the two. The present investigation was …

Behavioral and Psychophysiological Responses of 4-month-old Infants to Differing Rates of Infant Directed Speech
Infants of various ages across the first postnatal year have shown behavioral preferences (i.e., more attention) to visual displays when looking resulted in the presentation of Infant-Directed Speech (IDS) compared to Adult-Directed Speech (ADS). Although IDS differs from ADS on a variety of …

Infant attention to rate of infant directed speech in the context of varying levels of visual stimulation
Past research has found that infants between 1- and 4-months of age prefer extremely slow infant-directed (ID) speech to normal ID speech. Given that previous studies have paired the speech with a visual display, it was thought that perhaps the characteristics of the visual display affected infant …

Changes in the Content and Prosody of Mothers' Speech to Infants Across the First Postnatal Year
… examine the linguistic and prosodic content of infant-directed speech to infants, and to explore the relationship that exists between the prosodic features and the content of this speech, and how this relationship changes over the first eight months after birth. Analyses were conducted on …

Do Infants Discriminate Hyper-from Non-Hyperarticulated Speech?
… that adult caretakers usually hyperarticulate to infants by modifying their voice in ways that promote and sustain infants' attention. This articulation when engaging in infant directed speech (IDS) can result in "clear speech" by the expansion of the vowel space area. The degree of speech clarity …

Effects of Facial and Vocal Emotion on Word Recognition in 11-to-13-month-old infants
The speech commonly addressed to infants (infant-directed speech or IDS) is believed to have multiple functions, including communication of emotion and highlighting linguistic aspects of speech. However, these two functions are most often studied separately so that the influence of emotional …

Effects of Voice Quality and Face Information on Infants' Speech Perception in Noise
… and Molnar (2008) found that 6- to 8-month-old infants do not discriminate a simple native consonant-vowel contrast when familiarized to it in the presence of distraction noise (i.e., recordings of crickets and birds chirping), even when testing was conducted in quiet. Because the distraction …

Brain plasticity in speech training in native English speakers learning mandarin tones
… program utilized the acoustic characteristics of Infant-Directed Speech (IDS) to train monolingual American English-speaking listeners to perceive Mandarin lexical tones. Behavioral identification and discrimination tasks were conducted using naturally recorded speech, carefully controlled …

Vocal-Affective Weaning and its role in musical enculturation: children’s interest in music beyond the Infant-Directed Register
Well-established theoretical approaches to the Infant-directed Register (IDReg) draw a more or less tacit causal relation between it and all future musical engagement: the former establishes a basis for the latter. However, a mechanistic, observable chain of events linking these two phenomena has …

The Effects Of Parental Behaviors And Prosody On The Language And Cognitive Development Of Infants

The way …

Four-Month-Olds Do Not Prefer But Can Discriminate Infant Directed and Adult Directed Pitch Contours
… the role of pitch contours in directing infant attention to adult speech. Several studies have shown that infants from a few days old to 9 months of age prefer infant-directed (ID) over adult-directed (AD) speech. Moreover, 4-month-olds have been shown to prefer pitch contours that …

The role of context in infant preference for father's voice

The Effect of Hearing Impairment on Word Processing of Infant- and Adult-Directed Speech
