Plate, Samantha; Yankowitz, Lisa; Resorla, Leslie; Swanson, Meghan R.; Meera, Shoba Sreenath; Estes, Annette; Marrus, Natasha; Cola, Meredith; Petrulla, Victoria; Faggen, Aubrey; Pandey, Juhi; Paterson, Sarah; Pruett, John R., Jr.; Hazlett, Heather; Dager, Stephen; St. John, Tanya; Botteron, Kelly; Zwaigenbaum, Lonnie; Piven, Joseph; Schultz, Robert T.; Parish-Morris, Julia – Child Development, 2022
Infant vocalizations are early-emerging communicative markers shown to be atypical in autism spectrum disorder (ASD), but few longitudinal, prospective studies exist. In this study, 23,850 infant vocalizations from infants at low (LR)- and high (HR)-risk for ASD (HR-ASD = 23, female = 3; HR-Neg = 35, female = 13; LR = 32, female = 10; 80% White;…

Young Infants' Word Comprehension Given an Unfamiliar Talker or Altered Pronunciations
Peer reviewed Peer reviewed
Direct linkDirect link
Bergelson, Elika; Swingley, Daniel – Child Development, 2018
To understand spoken words, listeners must appropriately interpret co-occurring talker characteristics and speech sound content. This ability was tested in 6- to 14-months-olds by measuring their looking to named food and body part images. In the "new talker" condition (n = 90), pictures were named by an unfamiliar voice; in the…

Learning to Match Auditory and Visual Speech Cues: Social Influences on Acquisition of Phonological Categories
Peer reviewed Peer reviewed
Direct linkDirect link
Altvater-Mackensen, Nicole; Grossmann, Tobias – Child Development, 2015
Infants' language exposure largely involves face-to-face interactions providing acoustic and visual speech cues but also social cues that might foster language learning. Yet, both audiovisual speech information and social information have so far received little attention in research on infants' early language development. Using a preferential…

The Development of Language Constancy: Attention to Native versus Nonnative Accents
Peer reviewed Peer reviewed
Direct linkDirect link
Kitamura, Christine; Panneton, Robin; Best, Catherine T. – Child Development, 2013
The time frame for infants' acquisition of language constancy was probed, using the phonetic variation in a rarely heard accent (South African English) or a frequently heard accent (American English). A total of 156 Australian infants were tested. Six-month-olds looked longer to Australian English than less commonly heard South African accent, but…

Find Your Manners: How Do Infants Detect the Invariant Manner of Motion in Dynamic Events?
Peer reviewed Peer reviewed
Direct linkDirect link
Pruden, Shannon M.; Goksun, Tilbe; Roseberry, Sarah; Hirsh-Pasek, Kathy; Golinkoff, Roberta M. – Child Development, 2012
To learn motion verbs, infants must be sensitive to the specific event features lexicalized in their language. One event feature important for the acquisition of English motion verbs is the manner of motion. This article examines when and how infants detect manners of motion across variations in the figure's path. Experiment 1 shows that 13- to…

Perceptual Narrowing of Linguistic Sign Occurs in the 1st Year of Life
Peer reviewed Peer reviewed
Direct linkDirect link
Palmer, Stephanie Baker; Fais, Laurel; Golinkoff, Roberta Michnick; Werker, Janet F. – Child Development, 2012
Over their 1st year of life, infants' "universal" perception of the sounds of language narrows to encompass only those contrasts made in their native language (J. F. Werker & R. C. Tees, 1984). This research tested 40 infants in an eyetracking paradigm and showed that this pattern also holds for infants exposed to seen language--American Sign…

Expression of Affect and the Emergence of Language.
Peer reviewed Peer reviewed
Bloom, Lois; Capatides, Joanne Bitetti – Child Development, 1987
Results indicated that the more frequently the children studied expressed emotion, the older the age of language achievements; and the more time spent in neutral affect, the younger the age of language achievements. (PCB)

The Development of Categorization in the Second Year and Its Relation to Other Cognitive and Linguistic Developments.
Peer reviewed Peer reviewed
Gopnik, Alison; Meltzoff, Andrew – Child Development, 1987
Changes in children's categorization behavior between 15 and 21 months of age and the relation of these changes to developments in language, object permanence, and means-end understanding are reported. (PCB)

Is There a "Trochaic Bias" in Early Word Learning? Evidence from Infant Production in English and French.
Peer reviewed Peer reviewed
Vihman, Marilyn May; DePaolis, Rory A.; Davis, Barbara L. – Child Development, 1998
Analyzed vocalizations/verbalizations from children acquiring English or French in later single-word period to identify trochaic bias. Found that neither language's vocalizations were exclusively trochaic. French/English differences in iambic productions and acoustic realization of accent were traceable to adult input. Distribution of trochaic and…

Words and Gestures: Infants' Interpretations of Different Forms of Symbolic Reference.
Peer reviewed Peer reviewed
Namy, Laura L.; Waxman, Sandra R. – Child Development, 1998
Three experiments examined the relation between language acquisition and other symbolic abilities in 18- and 26-month-olds. Found that 18-month-olds spontaneously interpreted gestures, like words, as names for object categories. At 26 months, they spontaneously interpreted words as names and novel gestures as names only when given additional…

Semantic Comprehension in Infancy: A Signal Detection Analysis.
Peer reviewed Peer reviewed
Thomas, David G.; And Others – Child Development, 1981
Seeks to determine (1) whether 11- and 13-month-old infants directed their eye fixations to the referent of an object word said by the mother, and (2) whether there was a developmental shift in responding to object words at these two ages. Controls were set for response bias, stimulus preference, and maternal cuing. (Author/RH)

Infants' Learning about Words and Sounds in Relation to Objects.
Peer reviewed Peer reviewed
Woodward, Amanda L.; Hoyne, Karen L. – Child Development, 1999
Two studies examined whether 1-year olds' name learning during joint attention was guided by expectation that names will be in the form of spoken words. Results showed that 13-month olds, but not 20-month olds, learned a new sound/object correspondence, as evidenced by their choosing targets reliably in responses to hearing the word or sound on…

The Birth of Words: Ten-Month-Olds Learn Words through Perceptual Salience
Peer reviewed Peer reviewed
Direct linkDirect link
Pruden, Shannon M.; Hirsh-Pasek, Kathy; Golinkoff, Roberta Michnick; Hennon, Elizabeth A. – Child Development, 2006
A core task in language acquisition is mapping words onto objects, actions, and events. Two studies investigated how children learn to map novel labels onto novel objects. Study 1 investigated whether 10-month-olds use both perceptual and social cues to learn a word. Study 2, a control study, tested whether infants paired the label with a…

Nonverbal Communication Skills in Down Syndrome Children.
Peer reviewed Peer reviewed
Mundy, Peter; And Others – Child Development, 1988
Examines the nonverbal communication competence of 18- to 48-month-old Down Syndrome children. Results indicate that Downs children display strengths and weaknesses in nonverbal communication skills. Further, results suggest a deficit in expressive language is associated with a deficit in nonverbal requesting skill that had developed earlier among…

Infant Tests as Predictors of Cognitive and Language Development at Two Years.
Peer reviewed Peer reviewed
Siegel, Linda S. – Child Development, 1981
Assesses ability of infant tests to predict language and cognitive development and to detect infants at risk for developmental problems. The Bayley Mental Development Index was particularly capable of detecting infants at risk for developmental delay. The Caldwell Inventory of Home Stimulation identified home environment as a key factor in…
