Previous research reveals that novel words highlight object categories for preschoolers and infants as young as 12 months. Three experiments extend these findings to 9-month-olds. Infants were familiarized to slides of animals (e.g., rabbits). Infants in the Word condition heard infant-directed word phrases ("a rabbit") and infants in the Tone condition heard tones. During familiarization, infants' visual fixation was enhanced on trials with sounds (either words or tones), relative to silent… 

Figures and Tables from this paper

Categorization in 3- and 4-month-old infants: an advantage of words over tones.
Infants who heard labeling phrases provided evidence of categorization at test while infants who heard tone sequences did not, suggesting that infants as young as 3 months of age treat words and tones differently vis-à-vis object categorization.
Infants' learning about words and sounds in relation to objects.
The results indicate that infants initially accept a broad range of signals in communicative contexts and narrow the range with development.
Labeling Guides Object Individuation in 12-Month-Old Infants
This work provides the first evidence that infants as young as 12 months are able to use intentional and referential cues to guide their object representations, and suggests that a rudimentary version of the mutual-exclusivity constraint may be functional by the end of the first year.
Twelve-month-olds privilege words over other linguistic sounds in an associative learning task.
It is demonstrated that infants exhibit a preference for words over other linguistic stimuli in an associative word learning task, which suggests that by 12 months of age, infants have developed knowledge about the nature of an appropriate sound form for an object label and will privilege this form as an objectlabel.
Does Human Touch Facilitate Object Categorization in 6-to-9-Month-Old Infants?
The first evidence that touch may play a role in supporting infants’ object categorization is provided.
Specifying the scope of 13-month-olds' expectations for novel words
Labels constructively shape object categories in 10-month-old infants.
Do novel words facilitate 18-month-olds' spatial categorization?
The results indicate that 18-month-olds can use a novel particle (possibly assisted by a familiar verb) to facilitate their spatial categorization but that the specificity of this effect varies with infants' acquisition of spatial language.


Infants′ Detection of the Sound Patterns of Words in Fluent Speech
The results of these studies suggest that some ability to detect words in fluent speech contexts is present by 7 1/2 months of age.
Establishing word-object relations: a first step.
This work explores how infants in the early phases of acquiring language come to establish an initial mapping between objects and their labels, and whether the presence of labeling phrases increased infants' attention to objects over and above what pointing, a powerful nonlinguistic method for directing infants' Attention, could accomplish on its own.
Infants’ ability to learn and parse words
To what extent are infants able to detect words in the speech stream? Nine‐month‐olds attend to global information about words, such as the predominance of strong‐weak stress patterns in English
The nature and structure of infant form categories
Infant response to auditory familiarity and novelty
Form categorization in 10-month-olds.
Words as Invitations to Form Categories: Evidence from 12- to 13-Month-Old Infants
The data reveal that a linkage between words and object categories emerges early enough to serve as a guide in infants' efforts to map words to meanings.
The development of a linkage between count nouns and object categories: evidence from fifteen- to twenty-one-month-old infants.
In the experiments reported here, a match-to-sample task is employed to focus specifically on the development of an appreciation of the linkage between words and object categories in infants in the period just prior to and just subsequent to the naming explosion.
Understanding category members as "the same sort of thing": explicit categorization in ten-month infants.
Two habituation experiments were conducted in an attempt to determine whether 10-month-old infants are capable of explicit categorization, and suggest that infants do explicitly equate category members.
